Preferred Solution: Toshipa L550-00P Laptop will not boot suddenly

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Toshipa L550-00P Laptop will not boot suddenly

It's working OK now. I unplugged it from surge protect bar and plugged in another one and voila, it booted up. I also deleted the free defrag program, just in case.

About two weeks ago I placed my laptop down on the ground. When I picked it up two minutes later, there was an error on the screen which read something like "There is a problem with the cooling system, please contact your nearest Toshiba centre." Since then, the cooling fan has not worked.

I replaced the fan with a different one which also didn't work, so perhaps the problem is the system not the fan? Is there some setting within the system that allows me to manually turn the fan on and off?

Answer:Re: Satellite L550 - Cooling fan suddenly stopped working

> I replaced the fan with a different one
So that means you replaced it with another model?
Well, I think another fan model will never work because notebooks are specific products designed for certain series/models only. So you can?t change everything as on desktop computers.

In my opinion you should contact nearest authorized service provider. The guys can replace the fan and order a new one. If your notebook is under warranty, the repair will be for free. :)

I have attempted to install the Win 10 upgrade, only to find that it has crashed my PC and will not now respond to any commands. Only advise from MS was to create a Bootable USB with relevant ISO files to address this. Unfortunately in the Boot section, option for Boot command from USB is not one of the choices. Any suggestions or will I simply need to find a way to burn a DVD with the files and try to boot from this? Thanks John

I use a Dell Vostro laptop with Windows XP/SP3.

This morning, shortly after an automatic update, I had a system crash while away from the laptop; when I attempted to reboot, I received the following BSOD message:

c0000021a Fatal System Error
The Session Manager Initialization system process terminated unexpectedly with a status of 0xc000026c

I found a suggested repair process involving batch-running a file called "spuninst.txt", but that didn't resolve the problem.

Can anyone point me in the right direction? This seems to be a common problem, but the standard solution hasn't worked for me.

Thanks very much.

I have a Dell Inspiron 15-3521 running Windows 8.1
All of a sudden (after using it after ca. 1 year) it won't boot the Windows anymore. It says: "Media test failure, check cable" and "No boot device found. Press any key etc"
I actually had a software for checking my hard disk and it once said there was a problem with cables, but I really didn't pay attention to it.
Then I googled the problem and found out there can be something done with Legacy/UEFI booting. So I changed it to the UEFI. First of all "Windows boot manager" doesn't appear in the list and when I turn on the laptop it says twice "checking media [failed]" and tells me to restart the computer.
Can you help me to solve this problem? I have some important data on this hard disk.
P.S I had an unactivated version of Windows. Can this be the reason?

Answer:Laptop suddenly won't boot Windows anymor

Please run the diagnostic test to check the hard drive on the system by following steps below:
1. Power off system
2. Power on system, quickly tap the F12 key continuously until you see Preparing one time boot menu in the top right corner of the screen. In the boot menu, stroll down to Diagnostic and then click it. After quick tests, click on hard drive and then Thorough Test Mode. Report back any error code.

Two or three things have happened recently that make me believe that i am infected and hence am requesting help in this forum

Last night my laptop shut off all of a sudden - and i mean all of a sudden (did not boot down or warn me) like somebody flicks off a switch and the lights go out. At first I though it was the power but i was well plugged into the electricty socket and i also had battery back up.
This has happened twice before say a month back and three months back respectively but i did not give it a too much thought attributing it to freaky power fluctuation. Further, the time gaps between occurences were far and random
When i rebooted win 7 (64 bit with SP1 and completed up to date) asked me do a startup and system repair whcih i did and after a long wait i got a report saying

Answer:laptop suddenly shuts off without warning or boot down

There are only about five things that will cause a spontaneous shutdown. Overheating, bad power supply/adapter/powrer source interuption, flaky NIC, motherboard, or very rarely the processor. I'd check to see if it's overheating first and move on from there. Does it feel especially hot? Have you blown out the heatsink and fan area? Is your adapter making a good connection? Will it run on battery alone, is it holding a charge? Does it tend to happen when you are on the internet or accessing a network? The start up repair is normal, since the laptop did not get a chance to shut down properly, so I wouldn't worry about that, although it isn't good for it, of course.

So the laptop just suddenly shut down, no warning no nothing and when I try to start it again it doesn't want to boot up. I press the start button, the fan starts to spin for a couple a seconds and then goes silent for a few seconds after that it goes on full speed and I am unable to shutdown the laptop using the button on it, I must remove the power cable to stop it.Got any ideas what the problem might be?

Answer:Laptop shut down suddenly and doesn't boot up

It will just run with the fan at full speed forever I guess but the screen will stay black.

Wasn't sure where to ask this so it's here in the General category.

I'm looking for a replacement laptop with a few specific requirements. I can get most of them but the last one is proving difficult. So the requirements are:

17" screen with at least 1600 horizontal resolution.
Minimum of 4Gb RAM (8 would be nice)
Run 64-bit Windows 7

and finally, the cruncher:

Supports Intel VT (Virtualization Technology)

I thought the Satellite Pro L550-17U would be OK, but looking at the Intel site, it doesn't seem that the T6570 processor supports VT. And it would have to be supported in the BIOS anyway, and nothing in the spec says it will.

Anybody able to provide any help please? I'd like to stick with Toshiba, as I've had such great reliability from them, but would consider other makes (sorry Toshiba) if that's the only option.


Answer:Suggestions for new laptop - Maybe Satellite Pro L550-17U

Hello Roger

In my opinion most important question is: how much you are ready to pay for new notebook?
Satellite L is OK but don't forget that L Series is, generally speaking, not the best Satellite model.

For which purposes do you need new notebook?

I have a Toshiba Satelite L550-1cw that will not start, when i press the power button all the lights on the front edge light up, the fan starts and it looks for a HDD for about 2 seconds and then stops.

I have tried a new HDD but the same happens.
I have been told that the whole thing should be skipped and to buy a new one which is not an option.
I love this laptop and want to get it running again as its the best one that i have ever owned.

Please help


Answer:Satellite L550-1CW does not boot up pressing power button

Can you provide more information about this fault?
Can you see something on the display after pressing the power button?
Can you access the BIOS pressing F2 button immediately after powering up the unit?

Despite all this questions, I think that if nothing is visible on the screen there could be a serious issue with one of the following parts: RAM modules, motherboard, CPU/GPU.

From my experience the RAM memory modules are not very expensive (2nd hand could be good enough) and the replacement isn?t very tricky? in case the faulty memory cause this issue, the notebook could be fixed for a little money.

But in case of motherboard problems, the notebook repair procedure could be very expensive.

I have a 3 year old Toshiba Sattelite Pro L550-17U (Sept 2010). And it has worked perfectly ok since I bought it.

2 weeks ago, I turned it on, on my coffee table, where it lives 90% of the time, and nothing!!

Black screen, no keyboard lights (Caps/Screen/Num lock). Encouraging disk noise, On light was green, and charge light works when plugged in.

Tried external monitor, still nothing.

Continued by:

Reseating ram
Removing Hard Drive
Pressing F8 fairly rapidly after cold starting
Pressing F2 fairly rapidly after cold starting
Removed power and battery, replaced battery,

When it has been switched on (and looking rather black!). None of the keyboard lights respond (Num/Scroll/Caps Lock)

All to no avail.

Suspected blown motherboard.

I'm a little disappointed. I have only had one other laptop fail on me like this, and it was a 10+ year old travelmate!

Any other ideas?

Answer:Satellite Pro L550-17U fails to boot up, disk noise only


All you have done is right and these are typical steps that one notebook owner can try to check if this will help. Unfortunately there are no much options to test.
On this virtual way it is not possible to offer exact diagnostic but I also think that there is some serous mainboard problem. BIOS maybe? Who knows?

It is not easy to make decision what to do now. You can contact service and ask for help. They can check it and tell you what is wrong there but if the mainboard must be exchanged it can be pretty expensive.
It is really not easy to give you some good advice.

My name's Joe; tonight my laptop stopped working. Attempts to boot-up could be described as largely unsuccessful. Currently attempting a Start-Up repair; it's been running for about 1.5 hours now. In this post I describe the situation and hope that some altruistic person out there can/will help.

Personal Intro
Just a random 22 year old Canadian Grad student. I'm not particularly adept with computers. When I was growing up, my older brother was always the computer wiz in the house.

Anyways, this is my first post here so I hope I'm posting this in the right subforum.

Introduction to the Problem

I bought this laptop (ASUS U45J) about 1.5 years ago.

Everything has always been fine.

Earlier this evening, however, I dozed off for a few hours on what was supposed to be a 1-hour nap. When I woke up, I found my laptop screen was black; nothing was responsive.

I figured, "okay, no big deal. I guess it just crashed. Doesn't happen often, but whatever. Maybe it has something to do with the massive heat wave lately; and maybe it has something to do with me installing new software and drivers (Logitech Webcam) lately."

First noticing something was amiss...

I attempted to restart my laptop.

It said something about Windows not shutting down properly.

Being impatient, I told the computer to boot up as per usual (i.e., not in safe mode).

No such luck. After a loading screen (not the colourful blue one, but rather a simple monochromatic black and white load... Read more

Please help! I'm at the end of the rope for my laptop. Here are the specs:

Dell Inspiron 1545
Windows 7 64-bit
Intel Core Duo @ 2.20GHz
4.00 GB

Bought this laptop a year ago, worked perfectly up until around July 2012 when it suddenly failed to boot. Eventually in August it reached the point where I had reformat it using the recovery disks I made a year ago, bringing it back to factory settings.

The disks are NOT the installation disks!

After that it worked fine, until I booted it again on 9/6/12 only to find it completely slow and unresponsive, a window even appeared telling me Windows Explorer was unresponsive, etc., etc. Now it can only boot up to the login screen, but if I try to log on it'll get stuck at the "Welcome" screen. Which brings me to safe mode only. Here's the situation now:

- Virus scan with Microsoft Security Essentials came up with nothing
- Event Viewer gave me hundreds of Service Control Manager errors with Error ID 7001
- I did a disk check, it repaired the bad clusters but the problem still remains

What is going on??? Is it a hard drive failure? It hasn't made any strange noises, in fact it's sounded the same ever since I bought it. The loudest sound it makes is when it turns the fan on.

Even if I can't fix it, can somebody please help tell me what exactly went wrong so I can hopefully avoid it next time?

Answer:Laptop suddenly slow & unresponsive, able to boot only in Safe Mode

Hello Aitalas and welcome to Seven Forums.

Couple of things you could try. Microsoft Security Essentials is good, but no anti-malware product is 100% effective 100% of the time. (If there was such a thing we'd all be using it.) I'd suggest running two additional free on-demand scanners. Malwarebytes can be run in Safe Mode. Windows Defender Offline will be a bootable disc or flash drive that will begin scanning your computer before Windows 7 boots.


Windows Defender Offline

Once the scans are completed I'd try running a system file checker scan from an elevated command prompt (option two, first tutorial.) If any problems are found, run the scan 3 times rebooting in between each scan. The scan can be run from Safe Mode or in a command prompt at boot.

System File Checker

SFC /SCANNOW : Run in Command Prompt at Boot

If boot issue is still unresolved, one of the Forum experts prepared two troubleshooting tutorials that may help.

Back for more and, as always, a hearty thanks to anyone willing to give of their time. For the last several months I've been running a dual boot configuration--XP Professional and Windows 7 Home Premium managed by GAG Boot Manager--on my HP Pavilion dv4 2040us with no problems. I mostly use Win 7, but roughly twice a week I'll boot into XP Pro to utilize a legacy app or just to update my anti-virus. Yesterday, 4 days since my last visit, I booted into XP Pro and was, for no reason that I can figure, confronted with the classic "We apologize for the inconvenience . . ." screen that asks if I want to start Windows normally or use the last known good configuration or start in Safe Mode or a few other options. Given that 4 days ago I booted into the XP partition with no problems I chose "Start Windows normally." However, after entering the splash screen, the dots moved across the bar below the logo for 3 complete cycles then, half-way through the forth cycle, the screen went black then reset to the Power-On password request (I have the "Power-On" password set to yes in the BIOS, so I receive this request every time I power-up). Also, it's exactly the same if I choose any of the other options, Safe Mode, last known good configuration, etc.: 3 cycles of dots then half-way through the forth cycle it resets to the Power-On password request.

Answer:Suddenly Can't Boot XP Partition Of Dual-Boot Configuration

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:? Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Demystifying the Windows Registry.? Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to ...

Hello ...
I have had a Toshiba C850-A965 laptop for 4 years
and it's been working perfectly
untill one day recently, a message poped up saying that there's something wrong with the battery and should be replaced, but it was still the same, works for an hour and a half approximately
But, I went ahead and bought a new battery, the message disappeared
and i fully charged and then started the laptop
it worked for about 15 mins and then it shut down ( like u took the plug off from a desktop computer) without any warning
when i turned it back on, it was still fully charged !!! and the shutting down happend again and again :(
the old battery is still working fine
so that must mean that there's nth wrong with my laptop right? and the battery is bad?
please give me your opinions
thank you for your precious time

Answer:laptop battery problem, laptop shut down suddenly

Could still be a faulty battery. It can read the correct voltage off load, but as soon as you put a load on it, it takes a dive. The battery status symbol is just that, a symbol. The only foolproof method of proving it is to replace it with a known good battery. Do you have any good friends with a similar laptop ?

Hello, thanks in advance for your help.

I've had Win 7 installed and running for over 6 months now on a PC. This morning I awoke to find it at a System Restore page I've never seen before. It give me 2 options of trying to find the problem automatically (which gets nowhere) or manually. Then it allows me to try and perform a System Recovery through a backup, but that gives another error message. I've tried all the options that the screen gives me, to no avail. With one exception - it let's me choose the OS I am trying to boot, but there is nothing in the list to choose from. There is an option to "Load Drivers" which takes me to the System32 folder to select a driver(s). I don't know what to choose here?

I have no idea what caused this, I've installed no new hardware componets nor software that I can think of... It worked last night before going to sleep, and this morning nothing. I have had no problems in 6 months whatsoever, and the machine runs 24/7.

Hey-yo all. I got a little dilemma--last Thursday my system's working fine, nothing wrong, and I shutdown. I come back last night and turn on my system, and Windows doesn't boot anymore. It gets to the splash screen where the green loading bar moves (to show it's loading), but now this screen stays on for nearly three or four times as long as it normally would, and when it finally does finish and move to the next screen, it stays black, and after a few seconds a brief BSOD flashes and the system reboots (this isn't up long enough to read anything other than to see a BSOD).

I've tried booting in all the safemode modes but it does the same thing no matter what. I can't find my installation CD anywhere (I think I put it somewhere specific so I'd always know where it is... and forgot that specific place), which is probably what would help the most. One of the safemode options was to check the integrity of the hard drive using something like a "Windows kernel" and that said there were no errors.

I'm not sure what could've happened considering the system went from perfectly fine to a dud without anything more than a shutdown. Any tips for figuring out a solution? It's nice this had to happen when all my term papers were coming up for being due

Answer:XP sp3 suddenly does not boot


It might help knowing what the BSOD message says.
To stop the PC from restarting after throwing the BSOD restart the PC then press F8 to go into the Windows diagnostic startup menu and select Disable automatic restart on system failure. Boot the PC normally and it should stop when the BSOD is thrown.

Let us know what it says.
(Usually the message is something like IRQL_NOT_LESS_OR_EQUAL or it gives a file name that is causing the BSOD.)

I was just using my PC and suddenly got a BSOD coded 'BAD_POOL_CALLER'. The PC restarted itself and wouldn't boot up anymore.
It goes through the Windows loading screen, shows a black screen then a blue screen :

Then :

Then stuck in this for a while :

Then another black screen and restart.

The PC starts normally in Safe Mode. I tried Startup Repair(obviously) and even System Restored to a working state. Then I uninstalled my GPU driver with DDU as an attempt to see if the GPU was the problem(cuz nothing else could be).

Now the only thing left is to clean install the Windows which I want to avoid totally if possible. Cuz II've tons of software & customization installed and it'd take a long, boring time to do them again.

In May I built a new computer- Specs as follows:
QX6700 Quad Core cpu, EVGA 650i mobo, 8800 GT videocard
2GB 6400 DDR2 RAM, Seagate 250 GB SATA hdd
(2) DVD RW decks
Scanned with AdAware, Sbybot S&D, Windows Defender, AVG
XP pro

It ran beautifully until a couple weeks ago. It powered up ok but stopped at the black screen that lists some specs, "hit Delete to enter BIOS, ESC to enter boot menu" etc. I thought it may be the harddrive so I bought a new one, installed XP again and it was fine for a few days then did the same thing. I tried plugging it in a different SATA port on the mobo and it was fine for awhile then repeated the same behaviour. I replaced the mobo battery too because I noticed if it was unplugged/moved it reverted to the original BIOS date/time. It seems fine for awhile then repeats the behaviour. I formatted the original hdd and it's just blank but installed.

Answer:XP suddenly won't boot

If you can, boot the computer in safe mode. Click start>run>type eventvwr.msc Click ok or press enter. Look at the event viewer for any errors. Goto start>run>cmd press enter or click ok. Type chkdsk c: /f /r /x It will ask you run the scan on reboot. Select yes and report the findings.

Computer was running fine, I left it and when I came back the screensaver was running as normal. When I started to use the pc, it was frozen. The cursor would move, but when I clicked nothing would happen. Tried CAD to bring up task manager, but nothing happened.

I ended up having to turn computer off manually with on/off switch. Upon reboot I immediately noticed strange lines displayed onscreen as pc booted. When it gets to a certain point, the boot up process freezes, then shuts down.

I am able to boot in safe mode.

As the pc tries to boot, I notice that the graphics are distorted.

I have run virus/spyware scans and nothing shows up. (I'm always scanning for this stuff: Norton 360, Spyware Detector, Webroot, Spybot, System Cleaner)

Up until this happened, I noticed nothing in the use of the computer indicating any problems.

I recently bought a new computer, part by part. This is the first time i've done this, so I was expecting some problems, but now i'm thoroughly confused.

After installing 64bit XP and all of my drivers onto my computer, i started updating my windows installation. After multiple reboots, eventually i was given a not so friendly message: DISK BOOT FAILURE. this was after having had windows running for less than 24 hours. I was told to put my windows CD into the drive and click enter.. this booted my windows the first time i tried, and failed to help me on subsequent tries, as it tried to have me reinstall windows. So, i reinstalled windows, and after installing some more drivers and a few reboots, i got a disk boot failure again.

Refusing to give up so easily, i figured maybe there was something with my brand new hardisk. I mean, the two ram sticks i had bought originally had been defect, so i had had to replace them, so why not my harddisk too? Luckily, i had another older harddisk that i installed windows onto. Eventually it ran into the DISK BOOT FAILURE too. Also while I had XP running, i was unable to drag and drop (doubt this matters, but who knows)
My computer setup is as follows:

mobo: GIGABYTE GA-Q35M-S2 (built in lan- and sound-card)
cpu: INTEL Core 2 Duo E6850 3.0GHz
ram: CORSAIR TWIN2X 6400C5DHX DDR2 (2x2gig ramsticks)

Answer:Suddenly unable to boot

This could be because:

1: Your HDD has had it and needs replacing
2: It is trying to boot from another source, i.e. printer with memory card slots
3: A Memory card / usb stick which is in your PC.

It can be a number of things

Try these things first:

1: Check in BIOS and make sure the HDD IS detected
2: Make sure the boot order seems OK, make sure the HDD is set to first boot device as a simple check.
3: Make sure no peripherals are pluggged in, i.e. printer (to rule out any 3rd booting options)

Also can you try a normal winxp disk and not 64bit?

The Ideapad Y530 I bought in September 2008 just suddenly stopped working. I think it's a corrupt hard drive, but how can I be sure? I woke up and found my laptop to be just a black screen. The one key recovery button did not work, and i tried just installing vista again from a DVD, but it would not work. I just get a BSOD when it goes to load for the first time. I found that all of my program files were deleted, and then in anger/fatigue I accidentally formatted everything. Anyway, I think it's either the hard drive or the video card. How can I find out for sure? Also, I need someone to send me my Windows Vista serial key, because I don't have it anymore (it faded from the sticker), so I guess that one Lenovo representative that is on these forums would have to contact me to verify my identity? Thanks in advance.

Answer:Y530 will suddenly not boot, what now?

for serial number you need to call lenovo support line.for the blank screen, one of your ram sticks, maybe both may be dead, to make sure, remove one of them and try to start-up your computer. if it doesn't work, remove another one and reseat the first one you removed. it's probably ram issue.

hey guys

I've got a new cpu that I just built in january. initially it gave me some problems but I managed to sort that out, and it worked fine for about 3 months. however last weekand recently I've started to get new problems.

when I switch o the cpu, sometimes it works fine. more often than not, it will freeze up on me. there are 3 scenarios when this happens:

first, it will go to the loading screen ( the one with your motherboard manufacturer and model with alll the pretty pictures and such) next, one of 3 things will happen:

1) it freezes there and I wait really long and nothing happens.
2) it will go next to a black screen which says: select proper boot device and re-bbot the computer.
3) it will go to a black screen and say: a disk read error occured. press ctrl-alt-delete to restart.

if 1) occurs, after about 5 minutesit will go to a black screen which tells me all my comp specs etc etc etc such as processor, RAM frequency, etc etc. at the end part something catches my attention : it says 3rd slave harddisk S.M.A.R.T failed. I have no idea what that means.

If however, the computer boots fine, one of 2 things cna happen- it works alright and is perfectly fine OR it hangs halfway through whatever thing I'm doing. so far I have even seen one blue screen .

I think that this is a hard-disk related problem, and has probrably nothing to do with the operating system. what is puzzling is that if it's a hard disk problem it should fail to boot all t... Read more

I would like to ask computer expert here, look at what‘s the problem? how to solve it? I have asked someone else, Nobody knows
So I've been running Windows Server Techincal Preview 2 and had it installed on a 240 GB Crucial SSD. A couple of days ago I ran Windows UPdate from the Sconfig option 6 and downloaded and installed the updates that it found. It said a reboot was required and I clicked OK to reboot. So it rebooted and then upon it trying to boot up again I started getting winload.efi not found errors and BSOD. Further investigation using 3rd party partitioning programs show that my previously formatted GPT disk is now listed as basic MBR disk. What would have done that? All the data is the same and the partitions themselves are the same. I used one of the guides here on Technet to initially setup and format the disk to the 4 partition (1 including hidden MSR partition). Format style was as such:
EFI partition-fat32 (Hidden)
MSR partition -"other"(Hidden
Windows partition- ntfs
Recovery -ntfs
diskpart and 3rd party programs don't show the MSR so it looks like only 3 partitions.
But with everything still the same, how the heck did it just convert to MBR disk?
A similar issue is noticed as well. I use the EASEUS partition master server edition program which includes ability to make a bootable PE disk. When I boot to that disk I am also seeing a 1MB unallocated partition showing on my disks. It is also affecting a couple of Basic MBR disks as well ... Read more

Recently I bought myself a new PC. Intel Core i7 920 processor, Asus P6T WS Professional m/b, Intel X25-M SSD as system drive, Win XP32, etc. It started out lovely, and it is still lovely once it has started up, but a couple of days ago it suddenly booted a lot slower than before. All I have done is to install MS Office 2007 and I have let MS update my system with numerous patches lately.

My boot process looks like this:
1. First I see the BIOS "screen splash", and it hangs around the same period of time as before.

2. A long period (5-10 seconds) of black screen

3. The XP logo on a black background for several seconds

4. Another period of black screen

5. The blue screen saying "Welcome"

6. Finally, the desktop appears

I guess there is not much to do about step 1 and that has not changed since I first started the machine

Step 2 and 4 is weird. What happens here? Why black screen for so long? This was not there from the start but has begun after MS Office and major MS patch update.

The time for step 3 has also lengthened since MS Office/major patch update enterred the scene. Why?!

Step 5 used to be visible for about 0.5-1 sec (remember I use Intel SSD as system disk), now it is visible a lot longer, 5-10 seconds.

Once the desktop appears everything seems to be back to normal, real fast , behaviour. I can't see or feel any differences once I start working, so I doubt it could be some sort of degradation of SSD performance, ... Read more

I turned on my comp this evening and was greeted with a non working state. The power light on the motherboard is on. When I hit the power button, the hard drive light and front power light comes on, all fans including power supply fan and video card fan come on. Both cd rom drive lights come on like normal, and then the cd drives act like they are trying to read a disk( can faintly hear them spinning). When I hit eject, one drive pops out a bit then goes right back in. The other one won't do anything. Their lights just blink on and off. I tried unplugging each one , but it did not help. This is all the comp does, nothing else, no beeps, no bios, nothing. No signal to the monitor either. I did try to use a boot floppy, but the comp does not get far enough to even atempt to access the floppy. I left it like this for some time, but no change. If I hold in the power button, the comp will shut off normally. Anyone have any thoughts on this ? I'm lucky to have an old spare that I was able to get back on the net.

I've got two computers in my room, sharing a wireless router. One is a desktop and is connected via ethernet cable to the router. The other is a laptop and connected wirelessly. I had a little trouble with the settings on both computers, but I got them up and running and they've been fine since.

Now, on to the problem. Today, for reasons as yet unexplained, the router lost connection. This happens occasionally and is usually solved with a restart of the router (turn off and on again). This seemed to work; it worked for the laptop but the desktop still couldn't open any webpages or RSS feeds.

I decided to restart the computer and see if that solved anything. Restarted it, and now the computer doesn't boot. I get the motherboard logo appearing and the POST screen - showing the RAM checks and the other scrolling information. After that, the computer restarts.

I haven't got a clue what would cause this; I haven't added any new software or installed/downloaded anything that could have potentially harmed the computer either.

I haven't got any recovery discs for this computer either; it's a few years old and I've upgraded some parts.

Question: Suddenly Slow boot


Out of nowhere my Laptop has started loading bios to finishing startup in about 15 - 20 minutes - excruciatingly slow! Up until this point it only took 3 minutes.

It literally came out of nowhere - I had encountered no problems that I could tell, especially concerning running speed, and have not installed any new programs.

There is no error message - the process is literally the same as a normal startup except unbearably slower!!

Once the system has finished loading, all programs seem to start/work as normal but sometimes with a delay in first starting up.

I'm running XP Service Pack 2, Intel Celeron M 1.7GHz processor, 1.37GB RAM.


(Sorry this isn't a bump - just wanted to say I have a feeling that it might be my hard drive that's dying... could anyone give their opinion as to if I might be right?)

Answer:Suddenly Slow boot

Hi .You can run a diagnostic on the hard drive. These tools are available at the respective websites of hard drive manufacturers. You should download and use the proper diagnostic for your drive.Hard Drive Installation and Diagnostic Tools - Since the system boots, I suggest that you consider running a series of scans for malware, once it boots. The fact that SP3 isn't installed indicates the possibility of your system being vulnerable to malware items which have been counteracted (at least, in part) by critical updates issued since SP2.Those persons that devise malware...don't stop just because users have SP2 installed. SP2 debuted over 6 years ago and there have new methods of attacking a system devised since then...which won't necessarily be overcome by having SP2 installed.I suggest that you try a couple of these free online scanners to see if anything has slipped by your protection:(Be advised that some of these scanners will pickup things in "quarantine" from other anti-virus programs - so review the results carefully) Read more

This started a couple of days ago. I have a Packard Bell, 2.80 GHz, 512 MB RAM, running Windows XP. I bought it around 18 months ago.

Here's the problem. A couple of days ago the printer reported a communications failure with the computer. All the cables were seated OK so I shut down Windows and restarted to see if that would help. The computer wouldn't boot. Puzzled, I switched off and then I noticed that the side of the laptop was very warm. Checking underneath I found that the area above the battery cover was very, very hot, and this heat was radiating to other areas.

I unplugged everything and left the laptop to cool down. After 30 minutes or so I tried again and this time it booted fine and ran smoothly. However, after around 40 minutes the same area as before had become very, very hot again. Worried, I shut the thing down again.

I have a couple of questions. Firstly, would a cooling device (I'm thinking of one of those pads on which a laptop sits to keep it cold), would such a device help?

Secondly, as the heat is centered on the battery area would removing the batteries be a solution? (The laptop is used on a tabletop at home almost exclusively and I operate it on mains power almost all the time.)

Thirdly, could it be a fan problem? I can hear the fans whirring occasionally, and looking through the vent I can't see any obvious signs of dirt, fluff, etc.

Any help would be greatly appreciated.

I have a Lenovo y50 and it used to boot in 12 seconds, but recently started to take over 30 seconds to boot. I've had this laptop for around a week now. It happened ever since I reinstalled my nvidia driver. Im not sure if its just a coincidence that it happened at the time I reinstalled it. I made sure all traces of the driver were gone before reinstalling it. The loading circle in the beginning of the boot used to move smoothly but now it visibly lags and moves slowly. I've tried the "Clean up my PC" option and it still has the problem. Here is the event log:Link

Alright seems like i fixed the problem. I disabled fast boot and shut off the computer and then turned it on again(not restart). Then I enabled fast boot and now it boots at the time it did before. Very strange lol. Now it boots even faster, in around 10 seconds as opposed to 12, but its probably because of all the tips I was using to lower boot time that wasn't really solving the main issue lol.

Alright the fix from before only worked the first couple of boots and it just went to taking a long time to boot again. I recently revisited the problem and found out it was the hiberfil.sys that was somehow causing the problem. By turning it off and back on again in cmd, it would boot fast again, but only for the first or first couple boots. So i wrote a batch script to automatically reset the hiberfil and used task scheduler to run it when I log in. Works like a charm

Okay, so I was programming on my PC, then I decided to shut it off and go take a shower. After I got out of the shower, I remembered that I needed to sync my iPhone, so I pressed to power button. The front led and fans lit up for under a second and the computer failed to power on. I do not know what happened, so I tried it a couple of more times... Bad mistake? So I read online that it could have been the PSU, but it has worked fine for the past 1 1/2 years, and the new parts I just bought and put together worked fine for the 30 days that I had them.

Sometime during this frustration, I read that the PSU has a 115 and a 230 red switch on the back of it. Not knowing what that really did, I switched it up to 230... The PC then turned on, but the power had always been on 115, so how could this have happened...

Now the worst part, the POST failed at the CPU. I have an ASUS motherboard which has leds all over it to tell you what component is being tested. I thought the CPU was getting overloaded with power, so I just turned it off and then tried another technique. Plug 8-pin connector into the CPU spot on the motherboard... Did not work. So I reverted back to everything (230 to 115, 4-pin connector) and just turned left the computer off for about 5 hours.

Sorry but no way anyone on the planet could possibly explain it. The best we can say is that the machine was hot and needed cool down time. Maybe the PSU reset itself. We don't know and can't possibly know.

This problem started after I changed out the cpu hsf. I really don't know if it's related to me changing out the hsf or not. After the evga splash screen and the other screen that shows the irq assignments, my system "hangs" for atleast a few minutes, shows a blank screen, before the windows splash screen will show. This lasts for atleast 3-4 minutes. Before, the windows splash screen will show right after the screen showing irg assignments.

So far I've tried defragging, scan disk, and fixmbr. Nothing seems to work. I've tried to clear the cmos and restoring the system to an earlier checkpoint and that doesn't seem to work either. I've tried reseating the memory modules and the cpu, but my cpu seems to be stuck to my board.

Answer:Suddenly slow boot times

I don't know if this helps but I just had a very similar problem.
Windows would "hang" for about 20 seconds right after ' Verifying dmi pool data' and before the windows splash screen. It just showed a blank screen for a while.

I noticed that if I hit the Delete key a couple of times during that Pool Data message, the system would continue to boot right away. Try it.

I'm pretty sure it has to do with incorrect drive assignments.

This solved it for me: Disconnect all your drives (including any usb drives or card readers) and reboot, go into your bios and save changes then shut down. Now just connect the drive containing your windows installation and go to your bios again save changes and startup windows. The problem should be gone now, on the next reboot connect another drive and so on

Good luck!

I've been experiencing crazy long boot times recently. I've always had this problem to a certain extent, but it's getting way worse now. When I first got this and until a couple weeks ago, it had been rising from about 60-70 seconds to a minute and a half and up to two. Suddenly, today it skyrocketed to 270 seconds - almost 5 minutes. I rebooted 3 times and all of them took upwards of 200 seconds. I have no idea what is going on, as the only event log I have without code 100 is for a program that took 4 extra seconds to start. I'm leaving the details below, and I can see that prefetch, explorer, and the postboot times seem to be the culprits, but I'm not sure how to deal with that, especially since my previous 2 reboots yielded results different to both this one and each-other. I have a quad-core AMD FX-4100 running at 4.1 GHz and 8 gigs of ram, so I don't think it's a hardware issue. I do have an HDD so I expect slower boot times than brand-new SSDs, but this is ridiculous. I do have quite a bit of files in it, but it's relatively defragmented and I have trouble believing that's the reason for it taking almost 5 minutes to boot. Any help would be greatly appreciated, and I'd like to avoid formatting as much as possible, as it would take forever to back up all my files.

I have a Gateway GT5028 desktop computer with 2GB ram and a GeForce 8600 GT graphics card with Windows XP.

For some reason, my computer suddenly started booting up with no display whatsoever. The computer would start normally (fans, beeps ect...) but there would be no display on my monitor. It would say something like "check signal cable" as if there's no connection whatsoever. I've had my current graphics card for approximately 2 months with no previous issues.

I removed the graphics card and it booted fine while the monitor was connected to the onboard graphics card. However, I shut down the computer and found that it wouldn't boot second time. There's a blue light on the power button on the computer. When I pressed the power button, the little blue light came on and nothing else. No fans, no beeps, complete silence.

I've actually had this EXACT SAME problem once in the past and it was suggested to me (by a member of this forum) to remove the RAM sticks one by one to see if the computer would boot. Last time, the removal of a rogue RAM stick seemed to fix the problem.

My computer has 512 MB x4 RAM. I tried removing the RAM again one by one. I found that once two of four pieces were removed, the computer booted (without the graphics card in). I shut down the computer and tried booting again. It hasn't booted since.

Everytime I hit the power button, the little light comes on but no fans, no display or anything. It seems t... Read more

Hi Guys, Recently my pc has taken forever to boot up. A black screen hangs there for about 5-9 minutes before opening up in Windows 8.

I thought a virus was there so did a full scan using Kaspersky Internet Security 2013, nothing found.

I haven't d/l'd any new software recently.

I have tried to upload music to my micro SD card from my iphone, but the icon in My Computer is not showing, not in Device manager either.

Don't know if they are related but the problem started just after the above incident.

Hope I'm explaining this ok, I'm a silver surfer and not too 'with it' concerning technical data.

Look forward to any replies.

Answer:PC suddenly takes forever to boot up.

Welcome to the Gen help forum!

have you added any USB devices lately, any new printers, any USB drives?

If you have, try either powering them down before booting and trying it again.
If that is not the problem, we should scan your hard drive for errors, but not with SCANDISK. But before we get into that, just check for any USB devices. Sometimes a Printer will hang up a boot process, because it may have Card Readers in it.

Also, you may want to check out that SD card, pull it out and try to boot again. - If it's a bad card, it WILL hold up booting, and now you say you can't see it anymore, I think it may have gone bad. Actually you should check the SD card in a different reader, because sometimes the SD Card Readers will go bad.

hey guys

I've got a new cpu that I just built in january. initially it gave me some problems but I managed to sort that out, and it worked fine for about 3 months. however last weekand recently I've started to get new problems.

when I switch o the cpu, sometimes it works fine. more often than not, it will freeze up on me. there are 3 scenarios when this happens:

first, it will go to the loading screen ( the one with your motherboard manufacturer and model with alll the pretty pictures and such) next, one of 3 things will happen:

1) it freezes there and I wait really long and nothing happens.
2) it will go next to a black screen which says: select proper boot device and re-bbot the computer.
3) it will go to a black screen and say: a disk read error occured. press ctrl-alt-delete to restart.

if 1) occurs, after about 5 minutesit will go to a black screen which tells me all my comp specs etc etc etc such as processor, RAM frequency, etc etc. at the end part something catches my attention : it says 3rd slave harddisk S.M.A.R.T failed. I have no idea what that means.

If however, the computer boots fine, one of 2 things cna happen- it works alright and is perfectly fine OR it hangs halfway through whatever thing I'm doing. so far I have even seen one blue screen .

I think that this is a hard-disk related problem, and has probrably nothing to do with the operating system. what is puzzling is that if it's a hard disk problem it should fail to boot all t... Read more

Ok, story time. I was dual-booting Vista and Ubuntu. It worked fine, everything was great. Then I decided that I was sick of Sim City 4 crashing all the time. I remembered that it didn't ever do that in XP, so I popped in my XP disc, deleted my Linux partition and recreated it as NTFS and installed XP. Something obviously screwed up during installation, because it wouldn't boot afterwards. No big deal. I just booted from the Ubuntu disc and deleted and installed on my extra partition again. Through all of this, the Vista partition remained untouched and still appeared as normal in the partition editor. Only now, if I select Vista from the GRUB bootloader, it shows the "Starting up..." screen forever and never loads.

At this point, I don't even need to recover Vista, I just need to know if there's any way to get into that part of my hard drive from Linux (which still works just fine) to get out some important files that I really don't want to lose. Apparently something did screw up my Vista partition at some point, even though I never told anything to access it, because now if I look at my "Computer" menu in Ubuntu I only see the "Filesystem" partition which shows as 230 GB in size (the size that should be both of my partitions together).

Apparently the partitions got merged, so all I need to do now is figure out how get at the files from my other partition. It shows as mostly full, so they are there, but I can't easily find the... Read more

Today I was working on my Dell XPS Gen 3 (new in January 2005) and suddenly there was a "pop" noise and the monitor displayed its "off mode in 5 seconds" message which normally appears when the system goes into power saving mode.When I try to reboot here's what happens. First the Dell logo screen appears with the Dell logo and Pentium 4 box looking normal, but all text on the screen is garbage. Then the raid screen should appear but it is just all xxoovv garbage. Then the black Windows XP loading screen appears and it looks fine, but after a short time of watching the blue boxes moving across the banner the screen goes blank and the monitor goes into power saving mode ("off mode in 5 seconds").When rebooting I have tried F2 for the bios, F8 for safe mode, and F12 for Dell diagnostics but in each case I just get a complete screen of garbage.The four diagnostic lights on the back of the pc are all green so there's no indication there of what is wrong. The power light on the front of the pc shows green while the pc is attempting to boot but then goes out when the process stops.I have not recently changed any hardware or software, the surge protector seems fine, and the pc was working perfectly until the "pop".I would be very grateful for any suggestions of what might be wrong - cpu??? motherboard??? or ???

This weekend, I bought and installed a new SSD into my computer. I re-installed my Windows 7 (Home Premium x64 OEM) onto it, (fresh install, no migrate) and immediately formatted my mechanical HDD.

I went into my BIOS and changed boot priority. I also changed BIOS Drive positions, with my SSD as #1 and HDD as #2.

As soon as I got Windows installed, I started re-installing programs, setting up my admin account, and generally resetting my system, theme, Rainmeter, etc.

During boot, I get a message that asks me to choose OS - Windows 7, or Windows 7. It starts a 30s timer, then chooses the highlighted option and boots normally.

Then I started getting messages that I wasn?t running Genuine Windows. I clicked the ?Resolve Online? button, and downloaded the authenticator software, which told me I needed to buy a copy of Windows.
This irritated me, because I am running a key I bought legitimately, and I have the packaging and CoA.
I called MS Tech Support. I spoke with a very helpful gentleman. He checked out my product key. He had me activate my product, which I hadn?t done on my new install yet, and I got a ?Genuine? tag to appear under the Windows Experience Rating in ?My Computer>Properties?. He said I was good to go.

Please note that you have newest notebook model with newest hardware designed for Win7 standards.
Yes you can install Win7 anytime you want.

Win7 is fully supported and you will not have problems with it.
To go back on WXP has no much sense for me except you want to use some ?old? software designed for WXP only.

Anyway, which notebook model do you have exactly (L550-xxx)?

However last night it would not switch on at all.

.Please help as I am so upset as I have many many pictures of my grandchildren on my laptop and have been so upset that this has happened. I am in my 50's and not very techy!!

I paid a lot of money for this laptop and expected it to last me years....

I do not download music or films. Thanks in advance. Trish

Answer:Satellite L550-1CC does not switch on


I?m quite sure that in your case the hardware malfunction is responsible for your notebook problem.
What hardware part might be faulty?

This is not easy to say? I guess some essential components like motherboard as well as parts connected to motherboard like RAM modules could cause such issue.

The RAM replacement is not very tricky.
So in case you want to test if the new RAM modules would solve the problem, I would recommend you to visit some computer service points in your town just to check if such part might be the troublemaker.

In my opinion its not worth to purchase some notebook parts just to check if they are really faulty? the part should be checked before you would make a purchase

Since approximately 1 year im the owner of a Toshiba Sattelite L550-117. It has always worked quite fine. Lately though, my pc just shuts down.

It's not like a normal shut down, where every program is exited and then windows is shut down, but its more like a crash. It just shuts down, without any notice, and bam, i can restart it.

This has never happened before, and it started approximately 10-14 days ago. Has happened 6 times now. Just before it happens, my laptop starts getting really hot, it's actually a bit painful to keep your hand in front of the ventilator. I think this problem is caused due to severe overheating of a piece of hardware.

This problem is only occuring when i am in the middle of a gaming session. I Play Call Of Duty Modern Warfare 2 and World Of Warcraft. Both games should be easily handled by my computer. They have never been a problem for my notebook, and ive played them since i got this notebook.

This is typical behaviour by overhearing. That means that hardware reach critical temperature and when the sensors placed on mainboard register it notebook will be simply switched off. This is so called ?protecting mechanism?. This will avoid serious hardware damage.

What can you do?

Today it suddenly stopped, while I was working in windows. I restarted and again it went off after 15 minutes or so after booting. The booting was perfect. I tried some more times in windows it boots perfectly and then died.

I ran Linux, it was all working fine and I worked for more than an hour before it died again.

The way it dies is similar to what happens if I suddenly remove the power source, it produces a similar kind of sound that way.

Is that a power issue?

Thanks in advance


Answer:Laptop shuts off suddenly

Are you running it from mains? Or from battery?

If you are running from battery, then your battery could be on it's way out. You might need to buy a new battery

Otherwise it could be the motherboard. Especially considering it's 3 years old. If that is the case, start thinking about getting a new laptop.

Couldn't do ANYTHING, nothing responded...Walked about a bit, then a msg in LARGE type(like safe mode)appeared >>Windows has recovered from a serious error - a device may be to blame - save all work and exit I did a reboot but that didn't work either..had to hold in the I/O button. When I powered up again, I got a msg...>>Computer restarted after an unexpected shutdown. Windows detectd a possible device failure. The display driver for S3 GraphicsPro SavageDDR seems to be responsible for the system instability After restarting (2nd time) all *seems* to be responding OK. I went to the S3 site for driver update but was not encouraged to look for it 'cos of the warnings on the page... My Laptop is an Evesham XP2000+ 1.66GHz 512RAM, 2 months old.I looked in the Help & Support area on my Laptop at the error logs but nothing appeared for todays date! Should I be unduly worried about all this, or just see whether it happens again then panic?Ta in advance,AngeTheHippyx

Answer:Laptop suddenly froze...

As it all seems ok now, I would suggest a defrag, scandisk and after that wait and see.

I'm from India. I bought a HP 15-ay106ne laptop through my uncle in Abu Dubai on 01-01-2017.After a week I noticed that it didn't charge to 100% it reaches 99% only. After 15 days I noticed that it suddenly shuts down when the charging reaches 15% without any notification about plug-in. After few days it shuts down in between 15% and 20%.Now it's shutting down in between 36%-40% of charging. I found that the battery backup is also not good. Original backup is 10 hours but my laptop gives 5 hours of battery backup.I gave my laptop in to a HP service centre and they said it has a hardware problem. In India the spare parts are not available so please go to Dubai with your laptop.I preferred to buy it in Dubai because of its international warranty. But now they are not going to help me out of this problem.Please help me to get my laptop in good condition. And suggest me how to decrease the cycle count.

Hello All, My T500 shuts down suddenly at about 2 hour intervals. I am not sure if it has to do with overheating, as when the laptop is turned back on, the temperatures are very low. I figure a hot laptop can't suddenly jump 50 plus degrees. I imagine a temperature drop would be gradual.Also, when I have experienced overheating in the past, the laptop shut down wholly. Despite being plugged in, the light will go off and I need to do a battery reset. (take out battery, plug it and hold down power button while inserting the battery)But this was as if I had shut it down. It still charges and turns back on without issue.I checked the Event Viewer and have attached direct logs.I am hoping it is a graphic's situation and I need to reinstall the driver. any more information is needed, please let me know. Also, it is not warm to the touch when it shuts off.

Answer:Laptop shuts down suddenly

Hi Razorboi,
Welcome to Lenovo Community!
As per the query we understood that you are facing issues with Auto shutdown on your ThinkPad T500.

There is fix for the error file which you have provided, please click here to visit the page and follow the instruction from that.
Is the system fan running?
Boot the system into ?Safe mode? option and work for a while to confirm if the issue persists in that also?
Run ThinkVantage system update utility to check for the entire latest driver for your system.
Run Lenovo solution center and run system diagnose to check if there is any hardware errors showing in that.

Hope this helps.
Best regards,
Hemanth Kumar

Hi My Hp dv6 1315sa laptop working fine till a few days ago when it froze when playing frontlines fuel of war game, happened again with RA3 uprising and eroupean escalation. It doesnt reboot - just shuts down , then won't restart untill I remove that battery and power lead for a min or two. I tried checking the event viewer to lock down the problem - that wont snap in the mmc. Drivers are up to date, fans working, getting no error message but this is getting annoying, got me totaly stumped any help on this would be appreciated. Also sometimes the laptop shuts down for no reason with usual removing power supllies before it starts again. Hopefully someone can tell me how to make this thing at least half usefull for a few months more - then I'm definatly getting a desktop!!.

Hi guys,

Until a few days ago, my IBM laptop was running perfectly fine - but now it seems to have been infected by a virus (which i can't seem to locate)!

I've tried running AVG but all that really came up were tracking cookies, which i deleted to no avail.

I've used HJT before, however i'm in no way knowledgeable enough to know what to delete etc

The symptoms are basically- pop ups when i'm trying to use the internet (in both IE and Firefox - IE seems much worse though) - almost every time i try and click on a google result in Firefox it opens a new tab e.g., (adversiting sites basically)
Also, my laptop has just started to run much slower since i've been infected. For example, it takes ages to get past the Welcome screen when i turn it on.

I'd really appriciate any help that anyone could offer as its making my laptop unusable!

Thank you in advance!


Answer:Help! My Laptop has suddenly been infected!

Please follow the instructions in the below link and attach the requested logs when you finish these instructions.

READ & RUN ME FIRST. Malware Removal Guide

If something does not run, write down the info to explain to us later but keep on going.

Do not assume that because one step does not work that they all will not.
If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode. You can run steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:

Starting your computer in Safe mode

If you have problems downloading on the problem PC, download the tools on another PC and burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.

My Laptop is shutting down suddenly without any error message or without showing any shutdown screen it is just like working on a desktop having no UPS supply and all of sudden light goes off.....

I have check my battery,ram,motherboard,and also uninstall all drivers,install new windows but the problem still there....

and this is not because of overheating

so please help me out..

Answer:Laptop is shutting down suddenly!

"and this is not because of overheating"...

This IS an over-heating symptom. The cooling fan could be failing or giving the CPU/motherboard a false over-heating symptom. Also, check the bios settings , for fan control if any

Ok, so this is what has happened.....Was using my laptop, an Advent 7102 which had for about 4 years. It was running on battery and all of a sudden the screen went blank, and after just assuming the battery had died, plugged in to mains, but still nothing.All I am getting is the power light comes on, but nothing on the screen, no HD light flashes, neither do any of the other lights come on after pressing capslock etc etc....There is also no normal windows start up sound, which leads me to believe its more than just the screen that's gone.I have tried running the laptop off a seperate monitor, but does not work.I have checked the HD connections and ram connections, and all fine.Cant boot up in to BIOS or anything else as simply have zero screen, and pretty much zero everytrhing else.The only life the lappy has, is a green power light, and a running fan every now and then.Anyone got any ideas?Cheers,Chris

Answer:Laptop Died Suddenly

Remove battery and try on mains only.

I have a ASUS X550C laptop which I bought new around a year ago. It has a Intel IVY BRIDGE DUAL - CORE ULV 1.5GHz processor with integrated HD graphics, 6GB RAM and is running Windows 8.1.
I have regularly been using this laptop for gaming and it runs The Sims 3,The Sims 4, Simcity 2013, Euro Truck Simulator 2 and a few others quite well considering the specs it has. A couple days ago I downloaded and installed Farming Simulator 2015 and it has been running just as good as every other game.
I have just been playing Farming Simulator and after an hour or two of gameplay the laptop suddenly cut out. The screen just went blank and all the power lights went out, it didn't shut down it just cut out as if the battery had been removed. I immediately felt the laptop as I thought it may have overheated due to gaming, but no, the laptop was nice and cool.
I switched it back on, logged in and a little Norton 360 message on the bottom right mentioned something about a Trojan. I am currently running a full system scan on Norton 360 which is taking forever.
What could have caused this?
How likely is it to happen again?
Could cutting out like that have caused any damage?

Answer:ASUS laptop suddenly cut out.

Cut outs are usually due to overheat as you suggested but also a failing power unit can cause the problem with a momentary drop in voltage.
Probably need to stress the machine by running intensive programs to see if it does it again.

My laptop has been acting up for the past one and a half days. It started with being extremely laggy and now my desktop won't load OR freezes as soon as I click on something and I generally can't do anything.
I use Norton Anti Virus which has worked fine for detecting malware, but two days ago I downloaded 'Inkscape' and that program might have been infected. At least that's the only thing I can think of that could have caused that.
Do you have any advice for me?

Answer:Laptop is suddenly very laggy

Depends where you d'loaded the free Inkscape from. You might have installed several extra programs and toolbars etc 'freebies' if you didn't do a custom install. These PUPs (Potentially Unwanted Programs) would not be detected by Norton as you will have given permission (you didn't UNtick the boxes) during the install of Inkscape
Have a look in Programs and see what got installed on the same date/time as Inkscape

mine is a new laptop, i bought it only a few months back. it worked very smoothly initially. but suddenly it has gone very unresponsive. it lags a lot.

it has Intel B940 2nd gen dual core processor, 2gb RAM, win7 32bit OS.

it has gradually been getting slow.. first i thought its because of ram..
but recently its become very laggy. anywhere i click or anything i open, its now taking ages to respond.

i use ESET Smart Security 5, MalwareBytes, Advanced System care 5, and CCleaner too.
The antivirus and antimalware show no issues.
i clean my files and registry everyday with Ccleaner and ASC..

i think the hardware is decent enough.. n i also have so many security softwares... i still dont understand what is causing this sudden lag.

what do u think is the issue here.
can someone please help me out here.
