Computer won't boot (blank screen after BIOS)

Question: Computer won't boot (blank screen after BIOS)

I'm horrible with computers so I don't really know anything about my computer except that it's a Dell Dimension E521 and has Vista Home Premium..

My problem is that when I start my computer, after the BIOS loads and where it would normally go to a log in screen it just stays a blank screen (no cursor or anything.) I tried loading it in safe mode and it just freezes at "crcdisk.sys" and I also tried using system restore which says "the disc OS (c:) has errors) and tries to repair it (to no avail.) I also tried the "Repair Your Computer" thing and left that running for about 12 hours and that didn't do anything and so I finally tried to reinstall Vista but I couldn't even do that (the disc loads and lets me click install but it freezes after that.)

I guess I should say when my problem started.. I clicked a youtube link and then some error came up saying (I don't remember but it did say something about C (not the disk but the code)) well after that error Firefox froze so I tried closing it (through the task manager) but it just said access denied so I tried to restart my computer but explorer was frozen so I had no choice but to use the power button after which my problem started..

Also in the system settings error log it says there's a POST error Keyboard error every time I try to restart my computer..

the problem is when i boot up the computer, the busy light is constantly on and it will not show anything on the screen. i changed monitors and the same thing occurred, something is not allowing my computer to boot, maybe a virus, but how do i do a virus scan when the computer wont boot? i changed hard drives and the same thing occurred. i am sure that the problem is not monitor related but something else. all the wires and cords are connected and nothing seems obviously wrong. i put in a boot disk but it wont recognize it. any help would be great, if you guys need more information just ask, thanks

A friend of mine gave me a computer to try and fix and this one has me stumped. At first we were thinking his monitor was bad. Once I got the computer to my house and plugged my monitor into it, I realized its much more complicated. The computer turns on, green lights, fans running...but there is no picture on the monitor and the bios never beeps. I also figured this may have been a video card error but I put my card in and still, nothing. Any suggestions would be extremely appreciated. Oh, I dont know if this matters but this is a DFI Lanparty motherboard...not sure about the rest of the specs.

Answer:blank screen on boot and no bios beep

My computer has been running normally for quite a while now. Just the other day though, it started having a weird problem. I will turn it on, it will load the BIOS screen, then it will dislpay a blank screen for about 10 seconds before loading Windows XP. Windows loads normally and works fine after that. I think that this problem may have started after I installed and then uninstalled Dameon Tools, but I am not sure; that's just an idea.

It failed after attempt to install xp on this machine. I think it failed with the chipset driver installation.

Ever since then, it just won't boot up - won't boot with xp dvd, Spotmau, Linux dvd, ... etc.

Won't repond to F1, ESC tab to get into BIOS....

Felt so helpless & didn't feel customer support Toshiba was popular with.

Visited 1 ASP - maybe that guy was having a bad day. Just tried to turn on the laptop a couple of times and gave up and said "well looks like the motherboard won't respond... might as well buy a new one".

Any suggestions before I could get a day off to visit another ASP? Any ASP near Peel region that is competent and genuinely enthusiastic about helping Toshiba Laptop customers?

Any info would be greatly appreciated!!!

Do you don?t agree with the notebook technician that the mainboard is faulty? Ok I?m not a technician but the notebook can?t boot from any media anymore the mainboard could be faulty.

I had a similar issue that I couldn?t start my notebook anymore and the ASP told me that the mainboard is faulty and must be replaced. I agreed with the technician to exchange the mainboard and after this it was possible to start the notebook again. :)

So you should contact the ASP and speak with them again.

With the recent release of the W510 BIOS I decided to go ahead and update.  The previous BIOS updated fine within Windows 7 64-bit so I figured why not do it again.  I had no other programs open and the update seemed to have completed successfully with no messages other than to restart the computer.  Doing so the computer booted past the usual screen and got to the part where you see the ALT-S(?) message to boot from the NIC.  It stayed on that screen for a while so I turned the computer off, waited a little and booted it back up.  Now the system lights up the LEDs on the keyboard when you turn it on, however after that I'm left with a blank display and none of the LEDs light up for the keyboard (caps, num, etc).  I've tried unplugging the system, removing the battery and even disconnected the yellow battery under the keyboard for about 10 minutes.  I still get a blank screen on boot... am I screwed?  Who can I contact??

Hi,  I have an HP Envy 23-d010ea, which doesn't boot - at all. It switches on when pushing the power button, and doesn't react to any input, then restarts after about 60 seconds or so. I've read many posts addressing this issue, and tried all the proposed solutions. In particular I've tried- different keyboards, it's own, and others connected through USB - all USB slots. (btw not one LED switches nor flashes on the keyboard!)- hard reset (15 seconds power button while having disconnected everything).- switching it on with Windows button+B pushed down, in order to restore a previous BIOS, in case it's corrupted. Everything has failed. Can I mention that Windows 10 was recently installed (upgrade) on this machine, and I was merely doing a restart, aiming at reinstalling Windows 7 on it from scratch.  Please Help!Appreciate all the input.Many Thanks!

Hi everyone,
I have a Dell XPS 17 L702x that I was prepping to sell.  The basic specs are:
Intel i7-2760QM
16GB of RAM (4GB x4)
NVIDIA GeForce GT 555M with 1080p 3D screen
500GB 7200 RPM HDD x2
Windows 10 Pro
Like I said, I was prepping to sell the laptop.  The laptop was functioning properly.  I had wiped the HDDs clean and was in the middle of performing a clean install of Windows 10 pro from a USB drive.  I have done this before and never had a problem.  The install started correctly. I selected the drive that I wanted, and the installer wrote the files to the drive.  The laptop then restarted.  The power came back on, the fan started up, and I could hear the optical drive and HDDs spin up.  However, the screen stayed blank/black, and the Dell splash screen never appeared.  The activity light on the USB drive never comes on.  The normal functions keys do nothing.
Here are some troubleshooting things that I have tried:
I removed the RAM and HDDs.  I get the typical 2 beeps from not having any RAM.  Motherboard seem ok.
I have tested the RAM in my work Latitude E6430.  The E6430 will boot with the RAM from the L702x.  The RAM seems ok.
I have tested each stick of RAM one at a time in various slots in the L702x.  Same problem, blank screen, and no beeps.
I have connected the HDDs to the E6430 with a SATA to USB cable.  I can format and read/write from/to the HDDs.  The HDDs seem ok.

First of all, my computer is a computer that I built myself.

It is running on a Shuttle motherboard with an Athlon 3000+ processor

1024 mb of ram (512, and two 256 dual channeled sticks)

128 mb 9200 video card

20 gig hard drive win xp pro

floppy/dvd-rw cd-rw drive

I changed some BIOS settings, such as the FSB because I wanted it higher, it was only at 130 i believe? My motherboard can support up to 400. I set it to 200 if i remember, i also changed the setting from optimal to expert so it can allow me to make the FSB higher.

i then saved the changes and it tried to reset itself but failed and i got a blank screen.... and yes i am sure that my video card is in the apg slot and connected properly to my monitor.

now whenever i turn it on, i jusst get the blank screen

i need to know how to past this... it seems that my hard drive only makes a little noise within the first couple seconds that i turn it on

now when i turn it off and turn it on, the power supply works, led lights come on, fans work, etc...hmmm

please let me know how i can fix my computer, any ideas at all would be great

edit: i made sure everything was attached (eg. hard drive to motherboard)...still doesnt work

Hi guys,

Need your input on this.

Yesterday, while I was using my PC, the screen suddenly went black, and tried to 'restart' itself - ie it would go black, and turn on again, but there's no image, so it would go black again. After a while it would freeze and I would have to do a hard reboot.

It rebooted normally and I could use it again - for a few hours. This time, the same thing happened, except that at the BIOS screen, there were graphical anomalies (Checkered boxes with vertical lines) on the screen. This went on to the Windows XP boot up screen (the one with the progress bar), and then the blue login screen. The blue login screen was in fact blank without the Windows XP font in the middle.

However as soon as it got to my desktop, it would freeze and the same screen-blank-and-restart (forgive me for lack of a better term) thing would start looping again. Basically I cannot boot up Windows.

At first I thought it was an overheat issue so I let it to cool down for a few hours before turning it back on - but to no avail.

I did some searching on the net then and tried the following:
- switch out RAM sticks
- disconnect power supply to other less essential parts like CD rom and secondary hard drives (In case there wasn't enough power) for the GPU
- uninstalled graphics drivers (to which it allowed me to boot normally without artifacting and freezing. However artifacts were still present at BIOS and XP progress bar screen). However once I reinstalled th... Read more

I hope someone can help. I have a DELL XPS 2710 AIO PC. It is now 3 years old (unfortunately the warranty expired 2 months ago). It now doesn't boot at all into Windows. I get a blank screen. This started suddenly on a restart.
I've tried many things. Removing the HDD and RAM. If I take the RAM out I get the double Beep RAM not found sound, so I know it detects that. I've taken the Motherboard batter out to try and reset the CMOS including switching the jumper. I've swapped the RAM around, plus tried with different HDDs. The Screen still works fine as when powered up with HDMI in it shows other sources, but the HDMI out doesn't display anything on other screens.
For the life of me I can't get the BIOS to even display so I can't check the settings or reset it!
I think things are loading in the background but I see nothing. If anyone has a similar machine can you tell me the button presses to reset the bios as I'll try them blind to see if it works>
Anyone else with similar problems or ideas would be greatly appreciated.

I recently decided to order parts and build my first computer (here are the parts):
(I bought two of the memory packages for a total of 4GB, I also thought that the parts were compatable)

I assembled the parts and I thought the only error I might have made was in connecting the power supply to the components. However, when I pressed the power button all the lights and fans went on and I know the disk drive was working. Using a HDMI connection (and I tried VGA), the monitor remained blank. No bios came up and there was no beeping or shutting off or over heating.

Does anyone have any advice? I would really appreciate it.

I was playing Tiger Woods 2007 yesterday and my computer was running a bit jerky which i thought was strange but what I thought was even more weird was when it just turned off; no power, screen black all of a sudden, dead.

My machine is:

AMD 64 3700+ Clawhammer CPU
Asus K8N-e Deluxe Mobo
1gb Kingston RAM
250gb SATA drive
X1600 256mb Radeon Graphics Card

So, my spec isn't THAT bad, quite good i thought but it did just die! Now every time I turn the thing on I get life inside the case but nothing on screen (not even a bleep from the hard drive to say it's alive - though I can hear it spinning).

I've spent a while now taking out parts, blasting them with compressed air to remove dust, putting them back in, testing, retesting, re-retesting and so on. I've tried a friends graphics card ( i burned my last one out video editing and playing games! so checked this first!) and have tried different memory in it too in all the available DIMM slots so I know it's neither of these. I've looked at the processor and no pins are bent, no signs of overheating, the motherboard looks ok, i've tried booting from an old hard drive that was installed in the same system a while back (even though when I was doing this I though "well even if it was the hard drive I should still get life from the BIOS atleast!").

A little more than a year ago I built a decent computer (with your help. thanks!).
A couple of months later the computer mysteriously stopped working and the only sign of life was a lamp glowing on the motherboard. The fans also spun for less then a split second when trying to power the computer for the first time after plugging in the power cable. I figured it was either the motherboard or the CPU, but I didn't have the time or the money to look into it back then.

Now, more than 6 months later I've found the time and some money to try and take care of it. Yesterday I tested some parts and bought a new motherboard. After installing the motherboard, the computer will turn on, but it will turn off after a few seconds then turn back on and remain that way until i turn it off manually. During that time my screen remains black. I've tested all components except the CPU now so I'll probably have to buy a new one. But I have a few questions before I do that.

First off here is my Specs:
1x MSI Twin Frozr II GTX 580
1x Corsair TX750
1x Intel i5 2500k with stock fan
2x Gskill Ripjaws X 4gb
1x Samsung SpinPoint F3 HD103SJ 32MB 1TB
1x NZXT Hades case

and the old one was: Asus P8P67 Pro B3

Answer:Computer won't Boot, Blank screen

Have you tried to setup the system out of the tower. You could be getting a ground out. Just find a box to set the motherboard on and put on your video card ram CPU and power it up.
You will need to cross the two power pins to fire it up.Try with just one ram stick if you have two then try the other. after you try that and if you still have no luck. take off your CPU fan and put your finger against the CPU chip and fire it up for just a few seconds to see if the CPU starts to heat yo. If it does you still have voltage going to the CPU and it no doubt is still good.

Hi all,

I have an Acer laptop that will not boot. The Acer insignia comes up as it starts then there is nothing after that but a blank screen. I cannot even run a Windows XP recovery or reformat the HD. When I set the bios to boot to CD first. The same blank screen shows up.

I installed the HD into another known working Toshiba laptop and the same problem occured, the Toshiba insignia comes up then...nothing. So I don't think it's a hardware issue. I then took the drive out and put it into a 2.5'' USB HD enclosure and I was still able to see and transfer all my info from the drive so the data is still there, it just won't boot. Shamefully I must admit I haven't updated my virus protection in some time. Could this be some kind of boot virus?

Thanks in advance for all help offered.

If you can put the drive into an external enclosure and see it, can you format it from another computer? This may be the only option as Windows setup isn't working.

My Lenovo Z410 came with v37 BIOS dated 2013.I went to Lenovo website and downloaded and ran 8DCN40WW.exeInstead of taking normal time to flash, Windows started rebooting after only a couple sec. No bootup. No beep. No Lenovo logo. Power light comes on. Blank screen (no backlight). After 50+ bootup attempts I sometimes get the blue error message at bootup:InsydeH20 invalid firmware image. After changing RAM positions, and trying the Lenovo "rescue" bootup button, I got a bootup.CPU-Z still shows the BIOS is V37 (ie it didn't flash). I know I have Secure Boot enabled. So, to fix this I believe I need to force flash the old v37 BIOS image. SUGGESTIONS?HELP?

Forgot to mention.I already tried "draining power". IE disassembling my laptop, and disconnecting the battery and AC adapter, and holding power button for 60sec+ many times.It doesn't fix the issue.Also, the RAM position etc, obviously has nothing to do with anything. I was able to bootup with exact same 2x DIMM config as originally.

I have Windows XP Home installed on a Mesh computer. Everything was fine until recently but now the computer will not boot and there is absolutely no indication on the monitor. I plugged the computer into a friend's monitor and still there was no indication that the monitor was picking up a video signal (the amber light did not turn green and the screen remained blank). I then installed a known good video card but that gave the same result. I installed another HDD, changed the motherboard battery and got the same result. The computer will not autoboot from a bootable CD (and I can't get access to the system configuration menu). The fans are running and so there is power to the computer.

Any ideas what is wrong and how I can overcome the problem?

I'm going to assume my processor went out on me here, or motherboard.

I usually leave my computer on overnight and woke up to find it off the other morning. I turned it on, fans ran, power light and HD light was on but my screen was blank and in screensaver mode. I shut down and tried again a couple times and after the second or third time I had no power at all.

Thinking my PS was bad I replaced that but had the same outcome as above. I then tried a new video card and had the same outcome again.

Gigabyte 945P-S3 MB
Processor, can't find the paperwork but it is a core 2 duo processor, possibly 2.93GHz but it's 3 years old so maybe slower.

My processor heat sink was pretty loaded with dust so assume I burned it out. I seem to be pretty limited on inexpensive replacements but may try a Pentium Dual Core E6500, not too expensive but I'd hate to be limited in MB's if that is gone.

I put in a cheap 400w power supply to check that, then a Gigabyte HD 6450 video card.

I did pull the processor, all ram, reset everything but also took out the MB to look it over, no signs of burning.

I did try booting up without the floppy and CD drive, same result, as well as swapping ram to different locations, no change.

What should I look at next?

Answer:Computer won't boot, fans run, blank screen, screensaver on

If you do decide to get a new processor, make sure they have a decent return policy if it ends up not being the cpu but the mobo. The E6500 is sort of dated but they have a good price right now. I was looking at them just the other day for a cheap backup unit to replace my 1.8 northwood P4 system.

Welcome to the forum! Sorry to hear about your mishap. Try removing the BIOS (CMOS) battery for five minutes and then re-booting. If the hardware hasn't been damaged in the process of a BIOS update, and no BIOS corruption has occured, you should be able to boot with the machine now being reverted to the original BIOS... Good luck.

Yesterday my PC was working perfectly. No new drivers, updates, components or software have been installed. Recent virus scan was clean. Seemed to shutdown fine. However, I turned it on today and now it takes 41 minutes to boot up!! Heres the sequence of events:
23.35PM - Turn on PC. The monitor comes on, motherboard makes a beep, and displays the POST (Power On Self Test) as normal, then a dash _ blinks a few times in the top left corner, after that the monitor just goes completely blank (not even a cursor).

00.14AM - Finally the Windows loading bar appears. Longer than usual delay before the Windows circle icon appears, but from here everything appears to load fine.

00.16AM - Into Windows.
Ive reset several times and it always takes this long (even in safe mode). Though once in Windows everything runs like normal, no errors, no corrupt files etc.

Heres what Ive done so far to try and fix it: reset bios to default, took cmos battery out, removed all peripherals apart from keyboard and mouse, tried different keyboard and mouse, using different monitors, removed soundcard, checked connections, checked fans, tried different graphics card, run virus and spyware scans (clean), defragment, scandisk, registry scan, hard drive health checker, checked boot order.

I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.

the boot menu, Windows 8 starts to boot without difficulties.

I had to replace my HDD in my other laptop, well I put in blank HDD, well I try to start it up and I dont get bios or post. needing to install OS and software for the laptop. I tried the Ram trick, the hard system power reset and everything I could find that people suggested for the blank screen and bios problem.

Answer:Blank HDD, Blank screen, and no access to Bios

I don't know that much about laptops but when you replaced the hard drive, how did you know it failed and how do you know something else hasn't failed?

I have a Dell Optiplex GX280 and I have had some freezing issues and it has wanted to reboot on it's own for no reason frequently. I thought it was some malware that I couldn't detect so I was in the process of backing up my system when the really bad problem came up.

Now when I try to reboot the computer, the cpu fan runs faster than I have ever heard it. It sounds like it will literally fly apart it is running so fast. I can get no screen whatsoever and it will not boot; not even in bios.

I have read several posts about boot problems but I haven't seen anything about the cpu fan running so fast. When I try to boot the computer the light comes on it the front and of course the cpu fan comes on but no monitor signal and no boot at all. I have no control to try and help it.

It has the fan shroud like the Dell's are popular about having but I have removed it with no luck and put it back on. Once the fan came on normally and it booted up but I ran Tune Up Utilities to check the system and it crashed while running the scan. I haven't been able to boot it in any way again. When I push the button to start it all I get is the cpu fan running full force and I mean like nothing I have heard before. I can let it set for a while and it makes no difference. I am running a sata 120gig hard drive and 3 sticks of 1gig each ddr2 ram.

Ive got this old computer thats been working ok for years. i went out for a hour, and when i come back, its got the windows 2000 version of a bsod. its not the first time ive seen this screen, so i rebooted the computer. but when the motherboard's boot screen came up, i heard a click-whirr-beep sound eminate from the box. it sounds like it comes from the hard drive, im not sure though.
it then shows "f1 to retry boot f2 to setup" or something like that. f1 doesnt work, just reprints the same thing; f2 takes me to the bios.
any help would be appreciated.

The only thing that changed was I connected to a different monitor, installed a 2nd SSD and connected the motherboard speaker.I tried disconnecting the speaker, 2nd SSD, and any USB ports. I also tried taking the CMOS battery out for 30 seconds. It gets stuck at the ASUS splash screen where it has the press Del or F2 at the bottom. It is the only thing I see.

Hi. I have a dell inspiron laptop. My problem starts when i tried to update my bios from a07 to a15. While the update is running my laptop screen suddenly turned blank but my laptop is still on. What should i do?

Answer:Bios update fail. Blank screen while updating bios

Please check and see if you can get into BIOS. By the way list Dell model number and version of window. Ex: Dell Inspiron 3543, windows 10
1. Power off computer
2. Power on computer, quickly start tapping F2 key continuously. Hopefully, you'll be able to see BIOS screen.

So, been handed a laptop to take a look at, now the problem she has is that she was playing Sims one night and left the laptop on for 10 mins whilst she went downstairs, now when she returned the laptop screen was blank. She turned it off and back on again and the screen just wouldnt light up.

I had a look myself and can confirm that something is wrong, i asked if she had accidentally pressed any keys on the keyboard i.e FN+screen off and she said she hadnt.

I plugged it upto my tv using the VGA port both at boot and after leaving the laptop 10 mins and nothing, the laptop is booting, you can hear the fans and harddrive and the lights on the front are all giving a positive response but as above the screen wont turn on.

Anyone able to help?

Try to start notebook with AC adapter only or with battery only.
Disconnect both and leave it for a while and check if the same will happen again.
You can try to remove HDD and see if notebook will starts properly (BIOS and Toshiba welcome screen).

Do these small tests and post the result.

Ok. Trying to fix a friend's computer, and seem to have run into a rather strange snag.  Problem:  The computer will not boot past the bios screen. Details:  When you power on the computer, the compaq logo with intel inside shows up and has the <F1 Setup> and <F10 System Recovery> options listed as well.  And this is about as far as the computer gets.  After this the whole computer is just locked up, no buttons work on the keyboard no lights come on the keyboard ect ect.  I've tried mashing on the F1 key as soon as I power on the computer and I can manage to get it to say *entering setup* but it still freezes after this point.  I've already tried eliminating possible sources of problem, all expansion cards removed, HDD and Dvd Rom disconnected, single memory module (256mb ddr 2700), only power, vga, and keyboard connected.  Ive also used the jumper on the motherboard to clear the cmos hoping that would solve the problem, to no avail.  I've tried using a different stick of memory and different memory slot as well...  Tried using both a ps2 and a usb keyboard... Ive even tried pulling out the jumper for the bios password protection (even though it didn't have a password on it, just trying anything I can think of).  The installed bios version is 3.1, and that is about all I know about the computer at this point, other than what the website tells me of it.

I was using the laptop as usual when i think there may have been some virus activity - reason i say this is that my virus scanner closed down unexpectedly. I could not restart it from program files.

I restarted the laptop.

After the bios menu goes i get a blank screen with a flashing cursor - windows will not start.

I have done the following:
1)Create a bootable USB drive with Window XP recovery Console - on booting with this i can see three drives C:, D: as SDA? I can see the content of these drives so it appears as though my HD is working. I ran a fixmbr and fixboot but this did not resolve the issue.
2)Create a bootable USB Kaspersky virus scan - ran this without issue - it found a few issue (non on the disk boot sector) which i fixed.

One option was to copy off files from the laptop and then start it in recovery mode - So Itried to run the the laptop into recovery mode by hold down the 0 key on startup - the bottom of the screen then displays ***HDD Recovery mode *** and nothing happens.

Any help - further options would be greatly appreciated.

My 1 year Warranty expired a few month back so cannot send it in for repair.


Answer:NB200 Won't start post bios screen - blank screen with flashing cursor

I would try to scan for virus & malware with more than one virus canner, not just Kaspersky but also perhaps 2-3 more. Try Malwarebytes' antivirus and "superantispyware ". Sometimes even the best scanners miss trojans and stuff, but when you combine them you can get better results.

You can also try booting with Knoppix USB and copy files that way.

Laptop is approx. 3yrs old - W7 Ultimate.

Problem: laptop doesn't boot up at all, screen remains dead, only powerlight and fan indicates it is working. No BIOS screen options, no Toshiba Welcome screen, nothing...

Laptop MOBO gets power. Power light is on when on AC power, on/off light works, middle light (icon unreadable) is orange, no other active lights.

Bottom fan start and continues to spin.

Actions taken so far:
1) remove all power and press power button for 30sec then reboot
2) reseated memory
3) replaced HDD
4) blew out fans (user is a smoker - machine now stinks like HELL)
5) tried booting a Fedora & Fuduntu liveDVD, starts to spin, but then stops spinning. No OS seems to be loaded into memory.

No change

Sounds like motherboard problem? if the Toshiba splash screen does not appears, then this means thet POST (power on self-test) cannot proceeds and this means that this is an motherboard related issue?

I think that you will need to replace the mobo ;(

This problem started just last night and I've gone through a series of possibilities, and I'm pretty sure I've ruled out it being the Video Card, at this point I'm assuming it is the Hard Drive, but I wanted to get an opinion that has actual value rather than my own >.<

Last night I shut down my computer via start menu and went to turn it back on and when I did the screen went blank/black after the "boot menu" (not 100% sure what that menu is called, its where its kind of blue (i have an hp) and you can hit Esc, F9, F10, F11). After that happened I figured oh well maybe it just loaded wrong, so I shut it off, now when I hit the power button, rather than having to hold it down, I just press it once even lightly and it just shuts down completely. Normally when you hit it you have to hold it down to shut it down completely (or so I think).

Now I'm currently using an 'Nvidia GeForce GTX 260' video card, I swapped that out with a working one which was an 'Nvidia GeForce GT 520', not 100% sure if the 2 were compatible or not, but it fit and everything ok. Computer still did the same thing with the other video card. I didn't try the current one (in the broken computer) in the working computer, to rule it out completely. I just assuming that was the cast, besides it wouldn't fit in the other computer, or didn't have some of the cords.

Which is why I came to the assumption it is the Hard Drive, A; (as... Read more

Answer:Problem with computer going to black/blank screen after "Boot Menu"

See if you can boot off something like Hiren's Boot CD and then run a hard drive diagnostic tool.

That will rule in or out a hard drive problem. It could be that your Windows system files got corrupted and maybe you could fix by doing a repair of Windows from a Windows 7 dvd.

Hello everyone. I'm new the the forums here (as in just registered), but I need some help please. Basically after attempting to open firefox today (as I have probably over 20 times a day for the last year at least), I received a blue screen of death, and now my computer seems to be shot. I know how difficult it is to diagnose something without being able to see it, so I made a short little 4 min video of me trying to turn it on and what it does. Hopefully this has happened to at least someone before.

Blue Screen of Death - YouTube

Answer:[SOLVED] BSOD help. Blank screen after BIOS pop up and blue screen while trying to re


From the video you provided (which is great, by the way)... your system is failing to POST. Essentially if the system detects that a device or component is failing to provide the accurate information, which ensures that it would then be safe to run, the system will not POST.

From the looks of it, your hard drive or memory appears to be the issue which is the issue in most of the cases like this as you're BSOD'ing right after loading the Windows disc and after it loads the files necessary for the install.

My current advice:

1. Clear / reset the CMOS and try booting up and or loading the disc again.

2. If possible using another system, possibly a laptop... etc, download and run Memtest86+ -



Download Memtest86+ here:


Which should I download?

You can either download the pre-compiled ISO that you would burn to a CD and then boot from the CD, or you can download the auto-installer for the USB key. What this will do is format your USB drive, make it a bootable device, and then install the necessary files. Both do the same job, it's just up to you which you choose, or which you have available (whether it's CD or USB).

How Memtest works:

Memtest86 writes a series of test patterns to most memory addresses, reads back the data written, and compares it for errors.

The default pass does 9 different tests, varying in access patterns ... Read more

So I've had this computer for almost a year:
HP Pavillion a1250n
250G Maxtor HDD
2x 512mb DDR 3200 ram 400Hz (1Gig)

Brought to it's knees this weekend enexpectedly, I am attempting to install Windows XP Pro. I have used the maxtor diagnostic util to wipe the HDD to all zeroes, leaving one big unpartitioned space.

When I boot from the Windows XP CD it goes though the install just fine, formats the space, and copies the files, seemingly alright. When it reboots, it goes through the whole BIOS screen fine, it again asks to press any key to boot from CD, and if nothing is pressed goes directly to a blank screen, no cursor, no loading, nothing. Leaving it for up to an hour does nothing. Monitor is on, and signal seems active, but nothing is coming though.

I can access recovery console, but I'm getting in over my head at that point. Can anything in there help me?

Any advice is good advice, I messed with this all weekend long and it is getting old.

Answer:Windows half installs, blank screen after BIOS screen


When the PC reboots after copying files it should then read from the boot device, it may be possible that the BIOS is set incorrectly with the boot device not being set as the bootable drive.

Go into BIOS and ensure that the first bootable device is the HD you are loading windows onto, also remove any devices attached to the bootable drive such as any slave drives and that the jumper is set to master, not slave or cable select, if the CD rom that you are loading windows from is slaved to the master drive then place it on its own IDE channel and rerun the setup from scratch.

The only other time I have seen this happen is when the drive itself is flaky, that was only once though and I had to replace the drive.

Hi.The last time I started my desktop computer (Win XP), I got a blank screen, not even the initial bios screen.  The mouse and keyboard don't work either (i.e., the lights on the keyboard and the optical mouse don't come on) Please note the following:-I confirmed the monitor, keyboard and mouse work by attaching to another computer.-I opened the chassis and ensured that there aren't any loose cards (memory, graphics), or cables (power cables, drive cables, etc.).-I tried booting from the Win XP installation disk, but that did not work either (did not get the initial bios screen).- I had not installed any new software, made any configuration changes or made any BIOS changes prior to this problem.I'm inclined to believe it is a BIOS issue (b/c no initial bios screen) and not solely a hard drive issue (b/c did not boot from install disk) or solely a graphics card issue (b/c keyboard lights (e.g., caps lock) and optical mouse light do not turn on)Any help will be appreciated!!

In safe mode, the last line before boot-up freezes:


I have tried the option of "last configuration of functional settings" and nothing.

My battery seems to have been fried (only ever gets to max 70%) and I thought it might be due to a power surge. To check, I let it run down last night, to recharge it this morning and see if it would charge fully. I was watching a tv series on vlc, and everything was functioning as "normal" apart from the usual issues the trojan would dole out...I was completely surprised and utterly disappointed to find that this morning I have NO computer at all, while I have been patiently waiting for the team to help me axe this damned virus.

Answer:blank screen no bios

Frist - your warranty should be good, if I remember Toshiba policies. Go to Toshiba's Tech Support and they may help directly or find a local service place.

Second - You didn't say, but I'll assume your Notebook is plugged into AC. Have you checked the battery? It must be installed and have some charge on it to work even when using AC. Also, batteries have been known to go bad even if new. You may have heard of the big battery recall awhile back, although that dealt with batteries burning up (causing fires in some cases).

Recently my computer began to go to a blank screen right after the bios post screen. Nothing can be done, it just stays at this screen and never loads up windows. I haven't installed or changed anything in my system or bios before it happened so I'm wondering as to what would cause this problem and how to fix it.

I am however able to load up windows and use it just as normal if I were to change boot priority to cd/dvd first then hard drive. However if I were to change it back to hard drive first then simply a blank screen.

The reason that I believe it a hardware problem is that once windows is loaded using above method, I am able do anything that you could normally do.

Hey all,

I recently just got back from a trip out of the country and turned my computer on, and realized it was broken, my girlfriend just decided not to tell me she broke it hoping I would think I did it myself (thanks a bundle).

Anyway, I had 2 XP versions and a linux distro on my hd0, but was using a windows boot loader so just had the 2 xp versions on a list, if I picked any it would reboot the computer. Eventually I got into one of the versions after resorting to the "last known good config" option. I shut it down, and the next day I turned it on and before bios I just got a message on the screen saying something like "AVP569 something something 400e/500m" and then a flashing cursor. After some googling it looked like it might have been a problem with my video card. So I swapped the ATI x1650 out and replaced it with the card the computer came with, some low-end nVidia card. Now when I turn on the computer it doesnt load the bios either, but there is no error message, just a blank screen with a flashing cursor in the upper left corner.

I tried taking the mobo battery out to reset the bios config or whatever, and that didn't seem to work either. I've never encountered anything like this before and was just wondering if anyone knows what the problem might be, or how to go about solving it. At the very least it would be nice to be able to get into bios so I can at least take a look at things.

Answer:Blank screen w/ cursor before bios

Check all connections, inside (with power off), if no start after that, check for beep, or , beeps as it goes to start.
As you have removed, and replaced battery, it should go to default setup, and if that old original card is in there, it should beep, unless something is loose- next point of check, remove and replace ram stick/sticks, (try one at a time,if more than one)to see if that gets it beeping.
Once you have a beep. or, beeps we can see more to help - just tell us if/what they are.

Pull the HDD from the computer. When you power on the computer, do you get the Acer Logo screen? If so, at the Acer screen you should he message a quick message to press (key) to enter Setup, this is usually F2. If that works, shut down, remove the battery, and replace the HDD,replace the battery and restart and do the same thing.

I've got a Dell Inspiron One 2205 All-in-One computer that shows no signs of life except that it is receiving power.

When the power switch is pressed, it turns orange but that's all that happens and the monitor is completely blank. The CD tray is operable but no other signs of life appear. I removed the hard drive and connected it to a USB adapter - I couldn't see the drive in File Explorer on my other computer so I'm assuming it is dead. Would that alone cause the computer not to show anything on the monitor when started? I've ordered a replacement hard drive but I'm wondering if there could be other problems as well. It's about 10 years old and was running perfectly fine; I wondered whether the CMOS battery could be dead (but would that cause a blank screen?).

Prior to this problem
my PC case did seem hot but Musketeer device said 50 degrees C. Windows XP was experiencing more frequent problems on bootup recommending scandisk much of the time, TV card seemed troublesome.

I have opened up and had a quick look and all seems to be secure (except 1 of 4 very thin wires to the speaker ports.)
I haven't found or smelt signs of burning.

I also have a 3 year old PC P3 800mhz, 64MB graphics, think the memory is SD Ram, if any of this can help.

Answer:Power but No BIOS & blank screen

Sounds to me like your power supply, or possibly the mains (though I doubt it) had a power surge and blew your motherboard. Happened to me a couple of weeks back, my housemate a month ago and a family friend not long ago either! There was no smoke or burning smell either.

This would also explain no BIOS, and Windows becoming unstable before the event, because irregular power levels were being fed to your system.
If the psu has started surging, it would explain why the fans, drives etc are still working - power is still reaching them.

If it had been the RAM going, you would still get a POST / BIOS.
I doubt that the TV card has anything to do with it.
The only thing that confuses me is that you get beeping at all....

Not sure what you mean by "musketeer device", but 50 degrees is fine for cpu temp, and probably for case temp too.

If it was a psu surge, you will probably need to replace the motherboard, and I would strongly recommend buying a high quality psu (remember, high wattage rating doesn't always equal quality!) from reputable brands such as Antec or Enermax. Your psu has probably started becoming unreliable, and you don't want a replacement motherboard to go the same way! Additionally, you might invest in a mains surge protector.

Someone else might know different, or have a solution that doesn't involve buying a new mobo/psu....

Answer:blank screen after clearing BIOS

It should be easy to recover your files by connecting the drive to another machine and copying them to another drive or optical media. I would do that before proceeding.
Have you tried booting to a bootable CD/DVD?
This sounds like a serious issue with the motherboard or video card.

Hello, I just got everything in my case. New parts. I got the Asus M4A78LT-M motherboard and AMD Phenom II x4 3.2 955 am3 cpu. I got everything together and booted it one time, it started just fine. I went into bios to change device to usb thumb drive, bc it has my OS on it. I read that the mboard comes only working with 3 cores. I saw the setting under advanced-cpu and changed to all cores, while i was in the process of changing boot priority. Rebooted to a blank screen and unable to get in bios.
I tried clearing the CMOS data by turning off, unplugging, and moving the clrtc jumper. Also did the same and removing the battery. And then the ram. Then I tried unplugging all components(cd and br rom) & hd. To no avail. I also tried (with cdrom only as master) putting in the motherboard dvd to see if it would auto fix. Didn't work. I even d/l'ed the initial bios file from Asus and put on USB drive put in and turned on still didnt work.

I started my computer (Compaq Presario desktop 2gb ram, 140gb hd, 2.2ghz cpu, win 7 ultimate) a few days ago and it would show the HP splash screen and then go black with a flashing cursor in the upper left corner. I shut it down and restarted and went to setup and reset the defaults and it started. Now every time I start the computer I have to reset the defaults for it to boot.
I couldn't find anything similar to my problem, I looked.
I hope I put this in the right spot.

Answer:Bios splash screen then blank

Sounds like your systems CMOS battery may need replacing, is it showing the correct time and date?

In your Bios you should be able to find a list of voltages, see what it shows for the battery (vbat).

Hello everyone,
I've got a problem with my graphics card Nvidia 6800XT. It worked normally before but now I cannot start PC, it displays blank screen when I turn it on and I hear few beeps after that, but there's still nothing on screen. Everything works fine if I try with MX440 card or Graphics controller. I'm uncertain if it's really happening because of card and if I should test it on another PC. It may be because of power too, but I can't tell because everything was working fine before.

Here's some info about my PC:

ASRock P4i65G
Intel(R) Pentium(R) 4 CPU, 3.00 GHz x86
2.00 GB of RAM
Samsung SyncMaster 753DFX
Nvidia 6800XT (256MB) / Nvidia MX440 8x AGP (64MB) / Intel(R) 82865G Graphics Controller (96MB)
160 GB and 20 GB Hard Disks
230W Power Supply
Windows XP SP 3, 32 bit

Thanks in advance.

Answer:BIOS not starting, blank screen

Test the card in another PC. It will likely work fine.

Based on your specs, I'd say you need a new power supply.

I used the ASUS program to download and fix the BIOS that I had and BIOS 1.14 for my Motherboard (ASUS A7V8X-X) after installation I rebooted and my monitor wouldn't show anything a feeling went through my stomach that I had just screwed up big. I tried placing my 2 older video cards (ATI All-In-Wonder 9600, and an Nvidia card from 2000) the Nvidia card showed the screen and it said something about my disk crashing.

Now I'm sure you guys have seen this enough, or so I think. I have read around here and other sites relating to my problem, to an extent. Some problems others have mentioned relating to this blank screen are close to my problems, but the solutions to fix it is where I am having trouble.

My problem.
As of now I am typing this from a newly installed XP version on my hardrive (2nd partition).
I have Windows XP Profesional version 2002 sp2. When I turn on my computer everything is fine, Bios loads but after that the screen goes completely blank. I have tried running in safe mode but it freezes in the process.

I have had this problem before and managed to repair with the installation CD. All my files were ok. This time, after the repair (deleting and then copying files) it restarts to resume the rest of the installation, but the screen goes blank after bios. This time it did not work. I kept trying to repair but it says "there was already an attempt on upgrading Windows". It allows me to do the repair process again but I cannot continue with the installation because of the blank screen. I would really want to get to my files again. Any help would be very much appreciated. I hope theres a simple solution.

Hi nikar15 , 
Welcome to the Community Forums. 
Would you have the machine number? Check on the machine number from the sticker or check it from here ,just keep your serial number confidential.
Was it previously on Win8.1 ? Did you manage to create a recovery media ?
It would have to power drain the machine by removing the charger , battery and harddrive and to press and hold down the power for 12 seconds. 
Without the harddrive and battery , try going to the BIOS by FN + F2 or use the Novo button to start. If you manage to get the BIOS set up screen , go to the Exit Tab and load optimal defaults and save and exit. Turn off and put back the battery and harddrive and check.

Answer:updated bios with blank screen after update

It is doubtful that a cmos reset would fix the problem.

The first step is to check the video card and processor seating on the mainboard. If you have added a new processor, your video card may have moved during the install. Take the video card out and reinstall it.

Secondly, if the problem is in the BIOS then you will have to take it to an experienced technician to be reflashed. One of the reasons I bought a Gigabyte m/b was the 'dual bios' to save you from this sort of problem. I don't think ASUS have that feature (at least it not listed on the A7V8X web page).

Don't forget that the Sempron 3000+ runs at 1.8ghz or 2.0ghz depending on the model. So don't expect the bios to show it running at 3.0ghz.

I'm trying to fix a computer for a friend. When the computer loads, the monitor doesn't even detect the computer except when it goes into BIOS automatically. The light stays orange on the monitor, and it displays the "No Connection" message. I've plugged the computer into 3 different monitors with the same results.

I've tried putting other hard drives into the computer, as well as formatting the hard drive thats in there and loading windows on another computer, then hooking it back in, but nothing has changed with the display issues.

Does this sound like a video card problem? I thought that was the issue, but that BIOS screen thing showing has me a little confused.

It doesn't happen every time the computer goes idle but fairly often. They laptop keyboard still will toggle the LED lights on caps lock, FnLk, and backlit keyboard, but nothing will show up on the screen. Only way to get by it is to hold down the power button and hard reset the machine. I've checked Event Viewer for any oddities and can't find anything.

One morning the power went out, and I wasn't around. The computer just shut off. This computer has had hard shut downs before with no probs. Most of the computers I build usually do well.

Regardless, I turned my computer back on when I noticed it was off. It sounds like everything is booting up. I hear the HDD spinning the lights on the DVD drives light up, the fans go, and the monitor turns on.

The problem is, the monitor is blank. NOTHING comes up. I don't see the bios, nothing.. it turns on to a blank screen. When I shut down the power, the monitor displays the usual "no signal." The computer does one beep and sounds like it normally does when it starts to boot.

It was there for several minutes and nothing happened. So I decided to try it again...and Im still trying.

The support told me it's a problem with the bios, but since I cant access anything, I cant update the bios.
I tried it with a external monitor, with and without the battery, with and without the HDD (bios should be accessable without).
Always with the same result.
And as always such things happen after the guarantee has expired.

The hardware seems working (ok one time from many) and since a strange behaviour I wonder if somebody made a similiar experience or has a hint for me.

SO my sons laptop started to boot to a black screen with a mouse cursor. I can see the screen to select to boot from safe mode etc. but once the little animated windows logo stops it goes to a complete black screen with a working mouse cursor.

The laptop in question is... Acer Aspire-5560-sb256, AMD quad core A6-3400m, AMD radeon HD6520G.

I went to the Acer website and spent hours there looking on how to flash a bios but all of it required me to be in windows to do it. i get the impression the video works because i see the Windows animated logo and the mouse cursor works. Maybe i am wrong ?

I purchased a external hard drive enclosure and then scanned the laptops hdd on my computer with MSSE and Super anti spyware, were a few bad items but nothing alarming, i was able to transfer a few large game files to and from the drive with zero issues. So i am reasonably sure its not a drive problem.

I removed and re-seated the ram from the laptop, and it still seems to be fine.

I tried booting from all the safe mode selections and without safe-mode, neither of them resolve this issue.

Hey, first time posting here, so sorry if this is the wrong section or anything.

Lately my laptop has been experiencing a problem when I boot it up. After the Starting Windows screen with the glowing Windows logo, a blank black screen pops up that lasts for ages (I'd say at least 5 minutes). Afterwards the login screen will appear as normal.

When I log in, the desktop appears quickly, but when I try to start any programs, like my browser, they are slow and freeze often (usually I can run programs with no problem when the desktop appears). Sometimes the laptop will hang every three seconds. It takes a bit of time before the programs and the laptop run like normal.

I've tried several things without success:
-Uninstalling and reinstalling graphics drivers (I've never updated my drivers because no updates are ever available for my driver; is that normal? My laptop is about two years old)
-Defragging hard drive
-System Restore (I don't seem to have any restore points)
-Clean bootup
-Startup repair (or whatever that first F8 option is called)

Nothing appears on the screen when booting the computer from a powered off state. Not even the Thinkpad spash screen appears on the display when I press power. The backlight appears to come on but the display is still mostly black. So the LCD cables are at least partially connected. I doubt it was related since it was a driver, but the last thing I did in Windows was update the Wacom drivers since the pen was not tracking correctly in slate mode. This is what I triedPressed Fn+Home a few times then Fn+End a few times. The backlight increased in brightness but the display was still mostly black. Pull the AC power and the battery. Press the power button a couple times to discharge lingering charges in the capacitors. Installed the AC power only, then pressed power. Still nothing. Powered up the system then pressed the blue ThinkVantage button immediately. A single beep was heard but nothing on screen. Plugged system into a monitor with a VGA (D-Sub) connector and set the monitor to VGA input. Nothing appeared on the screen. Pressed Fn+F7 a couple times on the tablet to see if it was set to a different output for some reason. Repeated with another monitor with displayport. Again nothing on the tablet display. Pulled the RAM, booted with no RAM. No beeps. Reseated RAM and powered up, nothing on screen. I don't have any 1333 MHz DDR3 laying around.

Answer:X220 blank screen at boot, not even POST spash screen

You should've gotten beep codes when you booted without ram.  That's not a good sign.,
There isn't any key code that I know of to reset the bios without actually being in the bios.
The old procedure for ThinkPads was to take out everything that is in a slot, hard drive, RAM, wireless card and modem, battery and unplug the ac adapter and hold the power button down for 30 seconds and then put just the ac adapter back in and push the power button and see what happens.  If you get beep codes, put 1 stick of ram in and hit the power button again.  If nothing, take out that ram stick and put another one in and try it again.  Try it in different slots.  See if the bios splash screen comes up.  If it comes up, start putting components back in one at a time and rebooting each time until it doesn't.  Save the hard drive for last.
Are any of your indicators lit and does the fan come on when you hit the power button?
It sounds like you already tried most of that, but that's the only thing left to try that I can think of.

Hi Everybody!

My problem is the following:

When I start my formentioned notebook, the screen remains blank until the graphic screen of the OS doesn't load. So I get no toshiba screen, can't log into the bios nor can I install a new operating system. My laptop was in service twice. They replace the video card once, and the motherboard once. Please tell me if you had experienced something like this, and if there is a solution, then please share it with me. Thank you!

Answer:Satellite M100-222 Blank boot screen, but OS loads with screen


I?ve got two different Toshiba notebooks at home and never had any similar problems with my units.
In my opinion your notebook?s hardware seems to malfunction.
It?s hard to say what could be wrong because nobody here could test your notebooks hardware parts.
First of all the RAM modules should be checked. If the modules are ok then an motherboard itself or an part on the motherboard could be affected.

Bonjour mes amis.

I recently have started getting the infamous black screen of death at my computer's startup, very similar to this fellow user's problem. Basically, Blank screen on boot up, before login screen; slow startup. The black screen lasts at least two minutes on average, before the windows login screen comes up. Everything else runs fine!

I think it might be my antivirus, Bitdefender Total Security 2013, and I've posted on their forums about it, and I've gotten responses from other users saying:

The Black screen issue is known by BD Support till now they have not able resolved that issue.
hope BD 2014 resolves the issue.

And the booting time issue is been solved.

However, I uninstalled Bitdefender and the problem still persisted. I proceeded to uninstall every program i could remember installing before the problem started, so before the start of June. This was painful because I updated all my software, so everything was listed as installed recently.
My startup time after removing all these software is attached below; 156 seconds, compared to before with the speed ranging from 200-500 seconds, with the worst at 472 seconds.

Although this sped about my startup, I still got the annoying black screen issue. I am sure it is a software issue because the black screen is present, but lasts no longer than about 5 seconds when starting in Safe Mode with Networking, and is present even int he low graphics.
