Preferred Solution: windows 7 booting stopped booting

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.)

I have two HDs on my desktop PC and Win 7 installed on both of them. Recently there have been issues when trying to load either copy of windows.

One tells me there is disk inconsistencies and the disk needs to be checked. The other loads up the startup repair and tells me it's been repaired and to reboot my PC. When I reboot my PC the same process repeats.

I tired reinstalling a fresh copy of Windows but all that did is give me three Windows 7 OS to choose from when it asks me which one to load.

At this point I don't care if I have to format both of my HDs, I'd just like to get a copy of Windows working. It's weird that both copies on separates HDs stopped booting, could it be a virus? Anyways, please advise.

Answer:Windows Stopped Booting

Try booting with only one HDD connected. If that one doesn't work, try the other one alone. Post back what you find.

An image of your Disk Management screen would help too.

But here's my question: What reason do you have to load W7 twice on the same machine?

The system has worked in the past, and now after entering the user password the computer crashes and starts.
This may have been caused because the drive was run on the command "attrib -R -A -S -H *.* /S /D /L".
I do not remember if the system worked properly since then.

This has happened on 2 of my devices; a home built PC & Acer Laptop previously running Windows 7 Pro x64 & Windows Home Premium x64 respectively. Both have previously experienced little to no problems running Windows 7.

The PC was upgraded from Windows 7 Pro, then a clean build was successfully installed & ran for a couple of days. On the subsequent boot the Windows logo appeared with the rotating dots but it then stopped. On the reboot it went through diagnostics & I tried all options but there was no way to recover things.

Fortunately, I made a Macrium Reflect backup which I duly made & the PC re-booted successfully & has done ever since.

The Laptop was also upgraded, but from Windows 7 Home Premium with exactly the same thing happening. As it was an upgrade, I even tried reverting back to Windows 7 Home Premium which couldn't be done. When I checked the contents of the HD (having removed it from the Laptop) the Old Windows directory was missing! I've just restored things with a Macrium Reflect backup & await to see what happens.

I find this somewhat disappointing as I've been using the Insider Builds for several months without experiencing any start-up issue but to have this occur on 2 different devices within as many days makes we wonder if the retail version has been rushed out & is flawed.

Two weeks ago I purchased an ASUS M32CD PC Desktop with Windows 10 Home 64bit pre-installed, and now all of a sudden it's not booting.

When I set up my pc for the first time after I bought it, I mistakenly agreed to participate in Windows Insider Program, and shortly after setting my pc up, Windows Update automatically downloaded and installed a newer Windows 10 build which took about 4 hours to complete.

Since everything was still working great after the new build, and I had the option of going back to my previous build through recovery settings within 30 days, I decided to test it for a bit. Last night I decided I wanted to go back to the build which came pre-installed on my pc, and when I clicked on it via the recovery section, it said the files needed to revert back had been deleted and that I could not go back to previous build. So I decided to just Reset my PC instead. It gave me the option of keeping my files and settings or deleting all files and settings and reinstalling Windows. I chose the latter. It went to a blue screen that said Resetting your PC, and once it got to 2% complete, it abruptly ended and said there was a problem resetting my PC. I tried it one more time, and at 2% it again ended and said there was a problem resetting my pc, and I was given the option of going into advanced recovery.
From there I chose to continue to Windows 10, but it would not load anything. Since then I have tried to use the Windows Repair function, but it doesn't re... Read more

I shut down my PC the other day, removed my hard drive and CDR, de-dusted my case, put the drives back in and started the computer back up to find that windows couldn't load because "C:\Windows\System32\config\system" was missing or corrupt ...

Well I booted into the repair console, and the file is indeed there ...

So ... how could it suddenly get corrupted while sitting in its anti-static bag? More importantly, how can I fix the problem as that's not a file on the XP cd!

I'm not totally adverse to reinstalling windows, but I'd rather try and repair things first.

In this form I hope to solve PC errors, thanks for the help everyone!

I've a lot of PCs, all of whom have Windows 7 Enterprise and XP dual boot.

Nowadays, suddenly in many PCs both the OSs stopped booting, but I'll query about Windows 7 in this forum.

When Windows 7 starts to boot, as soon as the 'glasses' of the Windows logo appears, Windows 7 reboots.

On booting from safe mode, the restart happens after classpnp.sys is loading/loaded. I tried renaming that file, but then the restart happens on disk.sys, on moving that file too, it happens with fvevol.sys.

I tried to enabling boot logging (from F8), but there's no ntbtlog file in the Windows installation directory.

Please help me solve this PC problem!

Answer:Windows 7 suddenly stopped booting.

Welcome to SevenForums!

You mentioned you have many PC's with the same problem. The first thing I would look for is any updates that were installed on the machines shortly before the problems started.

If the PC's have System Restore active you might want to boot using a Install or Repair disc and restore to an earlier date.

Also try running Startup Repair, Startup Repair You may have to run it three times, booting between each run.

I try to never touch any machines that are dual boot, sorry I don't really have a lot of suggestions.

I have a Dell Inspiron n5110 and, like the subject states, the fan stops working after booting up Windows 10.
I just noticed this lately, so I can't really pin point the cause, but, I believe that it's only recent since my laptop ran smoothly in the past (I was playing the Witcher with medium settings, I was rendering 3d models/scenes with thousands of polygons, etc.), but now, it overheats every time I play and then shuts down.
I already tried cleaning the fan, replacing the thermal paste on the CPU and the GPU.
The fan works when I ran Dell Diagnostics and when the system is POST-ing (upon start up), then when the Windows 10 logo appears, the fan stops. I already tried looking for a driver, but I think fans don't require drivers...?

Any help/suggestion is appreciated. Thank you! :)

Had to to a format :drive /p:2, that is format with zeroing out the secondary flash drive which still had some boot loader, that activated randomly screwing up the system boot. Turns out the Asus Flash Erase is worth sh*t.

I've got Windows 8.1 Pro x64 installed for a month now and up until today everything was running smoothly.
Today the Os will not boot though, the boot process hangs during the loading animation, similar thing happens, when I try make a new install or repair the system using the repair tools from the dvd - when I click "Repair Tools" or "Install" nothing shows except for the blue background.
The problem goes away, when all other drives, except for the one with the OS, are disconnected.
I use a following build:
MB: Asus Maximus VII Gene
- Plextor m6e m.2 pci-e ssd<- Windows 8.1 installed
- 4 x WD Green as archive
- Crucial m4 SSD for vm's
Removing all drives except for the helps, however that is not really a solution. Disabling the SATA Ports does not help either, they have to be physically unplugged.
Also! - after disabling the Plextor drive an keeping the other drives connected, right after POST there is a message about a missing windows bootmgr. It's in my native language (now I have 8.1 en_us, a month back I had another installation on the Crucial ssd), so it seems the second bootloader is somehow interfering (?) although like I said, everything was running with no problems for a month.

I searched the threads for an existing post and I couldn't find one that matched my problem. Sorry if a solution has already been posted somewhere.

I have a new Acer 1410 w/ 4GB of DDR2 memory and a 1.6 CULV processor. It came with Vista Home Premium installed, but I downloaded Windows 7 Ultimate from my technet subscription. Because I don't have an optical drive I had to install from a USB stick. I did this without any problems at all.

Windows 7 has been booting fine and running great for about a week now. I haven't recenly loaded any new software or drivers. Yesterday I shut down my laptop normally; when I tried to reboot an hour later I was shown the "loading files" screen and was then taken to the Windows Startup Repair option. Windows spent an hour trying to repair whatever was wrong with my startup and I was finally given an error message that it couldn't make any repairs.

I tried going to the DOS prompt and fixing the boot manager and boot file; interestingly all this did was suddenly give me the option to boot Windows 7 or Windows Vista (!!!). I still get the Windows Startup Repair when I try booting Windows 7. If I try to boot Vista (I was curious) it takes me all the way to the login screen but then tells me I have files missing if I try to login, which is fine - I wasn't trying to set up a dual boot anyways.

I partitioned hard drive and everything. Then I installed XP Pro and Vista. Then I updated both and whatnot. I was on Vista then I restarted and booted into XP. Now when I try to boot into Vista it gets to the loading screen then it just restarts. I can still boot into XP fine.

Also I have lost all access to my BIOS. Does anybody know how to get that back?

I got a new disk drive for my pc and as soon as I got it installed Windows 7 would no longer boot after the start up screen. The error I get says "Windows has failed to start. A new hardware or software change may be the cause."

I've looked up the error and I've tried starting it in safe mode which won't work, I don't have a backup to reset my computer to and the option it gives me to repair the computer works but it sits on the repair screen infinitely. The only option I have found left is to reinstall windows or use the repair disk, but the computer was unfortunately gifted to me and was gifted to someone else before me so there is no disk. I just wanted to know of any more options before I got but a new OS to save my baby.

If that hard drive containing Windows 7 came from another computer and was installed in your computer, it's not going to boot and work properly.

My PC has two SATA drives, for storage, and two 128GB SSDs. One of the SSDs has Microsoft Flight Simulator (FS9) installed on it. The second is divided into two partitions: the first has the O/S, the second Microsoft Flight Simulator X (FSX).

The first sign of trouble was when aircraft fuselage textures stopped loading in FS9. Eventually, when this didn't clear, I decided to reboot. After I did so, the FS9 SSD was completely missing from My Computer. Tried rebooting a couple more times. No joy, and the Asus BIOS splash screen was taking ages to move onto the Windows is starting up phase, so I assumed that the drive had failed. I unplugged the faulty SSD, and all was OK. For two or three reboots...

Then, rebooting once again a little later, all I got was, after the BIOS splash screen, a black screen with one line of strange characters. A few letters and numbers there, but mostly stuff like you might find in Wingdings font, musical notes, patterns and shapes. I took a photo of this. I can post it if really needed, but don't expect the exact string will help much. It's the same string of characters every time..

I booted using a BartPE DVD and went into the explorer utility. The O/S drive itself is clearly OK (it would be a bit much for both to fail in 30 minutes!) as both partitions on it, the one with the O/S and the one with FSX, are accessible in BartPE and I can browse through the various folders.

Also, the small System Reserved partition with a folder called 'Boot' an... Read more

I was trying to install a ubuntu distribution to my primary hard drive (along side Windows 7) and at 99% of copying files the setup reported there was not sufficient memory to install backtrack. I cannot boot back into windows 7 as the computer resets before getting past the boot screen (shows 'starting windows' as normal then the screen blacks and takes me back to BIOS).
this process loops unless I select windows repair option, which does not fix the problem.
The Backtrack live CD won't let me delete the new, half-installed partition, so therefore I cannot change the windows partition back to it's usual (small) size of 55GB.

All help would be appreciated as I need windows on my PC for work

Hey there,

I have a Dimension C521 Dell desktop PC. It is a glorious computer; have had it for 5+ years now, and have had very few problems with it, and when, nothing a virus scan or system reformat wont fix. Its all been great, until we got this. My sister went on a website (Roblox, I think), and my brother occasionally plays Runescape on it. The anti-virus software has always been iffy with Runescape, showing multiple viruses, but we could always fix it. Not until Roblox went up. Shortly after, the PC froze, so I had to do a hard reset. While rebooting, we got an annoying ticking noise from the computer, down where I think the HDD is. I'm unsure if this is the "click of death", but comparing to Wikipedia's media of it, it sounds different. The noise is somewhat a click, sometimes going 2-6 times in a row, stopping, then repeating. Father (who has been helped before on this site; thank you!) thinks its the PC trying to boot from the CD drive yet failing. Well, being the ignorant person I am, I ignore it and continue...

Everything is similar, except...

Boot from CD:

What we think is that something deleted our boot drive.

So we find the system disk, and insert it. It downloads the files, and then goes to:

Answer:Windows XP PC stopped booting, lost boot drive?

Try pressing F2 and entering the setup menu. Once there, find the boot disk priority (usually in the boot tab) and make sure the hard disk is at the top of the boot list. If the hard drive is not on the top of the list the computer will try to boot from other devices and could cause the error you're seeing.

Just tried to add Crucial ram to a used Precision M6500 Win7 Laptop - 2.8GHz core i7 *GB SP1 on EBay last week. After taking advice from Crucial tech this laptop will no longer boot.
Apologies for the long explanation: 
Working machine came with 8GB (2x4) of Hylinks Ram. I added 8GB (2X4) of Crucial memory under the keyboard of the machine. The machine would not boot. Pulled memory from all four slots. Put one stick of Hylink and one stick of Crucial in battery side slots to see if they work together there. The machine booted windows. So I put the other Hylink and Crucial sticks under the keyboard. The machine did not boot.
I called Crucial. Tech told me to pull the cmos battery. Wait 15 minutes and plug it back in. This is were the real fun begins!
Now the machine won't boot windows under any condition. 
I pulled the the additional memory out from under the keyboard. The machine runs the memory test and blue screen flashes on and off in a split second. It goes into startup repair mode. And ends with the following report every top I push the start button:

"Windows failed to start. A recent hardware or software change might be the cause.... 
Launch startup repair (Recommended)"
Start up repair does not work. The machine will not boot Win7 with either 8 or 16GB in place.
So it seems pulling the cmos battery is at the bottom of this. But for the life of me I can't figure out why?

HiMy current pc specswindows 7 ultimate,hdd:320 gb(now replaced),1gb RAm2 weeks ago my lenovo R61 started showing fan error,I force fully sometimes closed laptop by pressing power button for 5 sec around 10-15 times because it never gets shut down,after opening it by pressing Esc key.Then I opened it,saw dust,cleaned fan dust.And it worked smoothly but after one day,windows stopped booting at logo glowing screen.It hangs there for so long.Again forcefully shut down.Luckily i installed ubuntu too on separate partition.It was working normally but few days later,ubuntu also stopped booting.Then  I thought to replaced my current hard disk(320 gb)  with my older one(It is 160 gb,it has windows 7 installed, i took it from my brother lappy of SL500).And my pc boots normally,it worked but again with some times showing fan error and on pressing Esc,logging inwindows 7,sometimes mouse automatically right clicks (i have updated mouse drivers).No fan is available in india of its model,although i have now extra one cooling pad,which keeps laptop cool.Questions:Is my hard disk(320 gb) has failed?Is my fan error eventually going to destroy my motherboard,if i do not replace fan?Why sometimes fan error comes and some times not, and why mousepad sometimes gets disabled on some parts like taskbar,and then it works,sometimes automatic right clicks ,then later works.?What is problem  

Answer:Fan error,windows stopped booting,replaced hard drive,Windows boots mouse problem

Typically, a fan error means you have a bad fan and if not that, probably a motherboard problem.  I would first try ordering a new fan (I will locate a part number for you).
Hard shutdowns do damage because the OS could still be writing system information when the PC suddenly goes off, and on the next reboot, you may have a damaged file.

Recently I purchased a laptop with windows 8 64 bit pre-installed in it. For my job purpose, I needed windows 7 32 bit. After searching the web and also using the information I got from this site, I disabled secure boot, deleted the recovery partition and converted GPT partitions to MBR. Then I shrink the Big partition in which windows 8 was installed to make room for the windows 7 partition. Then I created a new partition and installed windows 7 on it. After this whenever I switch on the computer, a message come up, saying that a required device cannot be found and windows is to be repaired. The only way in which I can start windows is to go to bios, select the boot options and then select boot from notebook hard drive.

Can anybody please tell me how this problem can be solved

Answer:Booting problem with dual booting with windows 8 and 7

when you created the new partition did you make itin front or behind the existing partition?

If your boot manager is looking to boot Win 8 on Disk 0 Part 1, and you created the new partition in front of Win 8, your Win 7 will now be located on Disk 0 Part 1 which is where the boot manager is expecting Win 8

Hi all,

I've just spent the afternoon trying to install a couple of SATA drives with the intention of removing the old ATA drives and putting a fresh XP build on.....but things have got interesting.

Established earlier that i needed to get the Samsung SP1312C SATA drivers, which i've been looking for (and still looking for)...however thats not the problem now.

The PC would only boot if i cleared the BIOS (jumper switch), and then it would only boot once. If i re-start after re-setting the BIOS to boot from CD the PC wouldn't boot (you could hear the thing mem check but no display)....reset the BIOS again and it would boot (viscous circle).

Situation i have now is that on startup i now get 3 short high pitched beeps followed by 2 low beeps. I've removed everything bar the graphics card from the PCI slots and all external peripherals so i'm running a CDRW drive, 1 60GB hard drive and RAM. I've re-seated the RAM and tried to boot with each indicidual stick in, tried a different Graphics joy. Beginning to think that the CPU has had it but the funny thing is after the beeps on startup you can still hear the thing POST and detect the Keyboard.

The last thing i have tried is removing the CMOS battery again, symptoms remain.

Any idea's?

I have an advent verona netbook which had win7 installed from new.

recently it was becoming very sluggish, this was followed by it not responding at all and all i could do was boot into safe mode.

Now it will only boot to the recovery options (startup repair) and regardless of what i click (attempt to fix error / reinstall windows / etc ) the computer just hangs, freezes or does not respond at all to key / mouse presses.

So what are my options ?

The computer has no disk drive and came with no install disks etc - so thats not an option.

I can enter command prompt from the start up repair so my inital thought was f disk and try to install my copy of vista on it which ive put on a memory stick - but even when i boot from the memory stick i get the options to install vista but then its just the same freezing / hanging and doing nothing .

Is there a way i can completely wipe the computer ?

Any help much appreciated as im at a complete loss now


Answer:win 7 has stopped booting .. what are my options ?

Burn a Win7 Repair CD to run Startup Repair which doesn't depend on OS files: System Repair Disc - Create. You can write ISO to flash stick using Win2Flash.

Make sure Win7's 100mb System Reserved is still marked Active so it will repair: Partition - Mark as Active.

If it won't start after running 3 separate Startup Repairs with reboots, mark Win7 partition itself Active to run Startup Repair x3 again to write the System Boot files directly to it as the 100mb boot partition may have become corrupt.

System Restore should be automated in Startup Repair, but run it next anyway.

You referred to a choice on your System Recovery Options list to Reinstall Win7, which means you have a Recovery Partition from which you should have made Recovery Disks. You can order these disks from manufacturer's Tech Support for a nominal fee if you didn't make them earlier.

You can also clean reinstall with the Product Key on your COA sticker following these steps: Reinstalling Windows 7

Copy out your files with Repair CD or DVD using this method: Copy & Paste - in Windows Recovery Console. If you can find the install.wim file in the Recovery partition which won't run, you can also mount it to run Factory Recovery.

Hello Forum,
I am new to Major Geeks and fairly new to Vista. Last Sunday the Vista OS in my computer quite booting up. It begins to boot, and then the screen goes blank and the monitor says 'No Signal' Do you know of a program i can run to find out what is keeping Vista from running?

Thank you, Dean

Answer:Vista stopped booting up

Are you sure the machine is not booting? The No Signal message means the monitor is not working. Have you checked the connections? Have you tried a different monitor?

Hello All,

I have a HP Pavilion zv5000 running XP and i can't get it to boot anymore.

It did boot and work for a few times after i got it but now it doesn't. It would do the initial surge where the fans come on but then it would silence and turn off after a few seconds and the screen stayed black.

I removed one of the memory sticks and booted, after the initial surge it stayed on unlike before, but it didn't kick on further and still nothing came on screen.

I did try a different screen from one of my other pavilions as i know they are prone to inverter problems but still it just stayed black.

Does anyone have ideas please, i really don't want to have to take it to a shop.

Answer:Laptop has stopped booting up.

If it was a faulty hard drive you would still get something up on the screen, with an error message relating to the hard drive, so that's not the problem.

Similarly, with faulty RAM. you would get a series of fault beeps from the BIOS which I assume you are not getting?

I assume you've tried turning it on while it's connected to the A/C adapter (in case the battery is flat)?
If yes, then it's my guess the motherboard is faulty. Only an inspection by someone who knows about the insides of a laptop can confirm that I'm afraid.

I've had this computer for several years and just recently it's been having various problems and now it's not even booting up anymore.

Some previous problems that led up to the boot up problem.

Most recently when using the computer, suddenly it seems to freeze up and after several minutes the display/resolution goes from my regular setting (I believe it was set at 1024x768 32 bit, to 256 color 640x480.

It was happening almost on a daily basis. It got so bad that instead of using the computer locally, I would log in from my laptop using Remote Desktop and using the computer this way instead. I was not sure if this was caused by a faulty video card or maybe the motherboard was having a problem.

I have an ATI All In Wonder 9800 AGP video card. It's been working fine for about 2 years but recently I was having problems using the TV tuner. When trying to use the TV Tuner I get driver errors. I've tried several different drivers from ATI but to no avail.

I'm running Windows XP SP2. 500mb DDR memory.

I'm running CA's Etrust Security Suite (Antivirus, AntiSpyware and firewall)
My last scans showed no viruses.

The last time my machine froze up and video went to 256 color, I rebooted my machine which will usually temporarily fixes the problem, but this last time the screen stayed black, no POST, no beeps, keyboard has just the numlock light on and nothing else lights up.
Fans go on, I can hear both hard drives spin... Read more

After my T40 started failing, I decided to get a T43p (off my boss). This machine worked perfectly for a while until earlier today. It wouldn't resume from suspend, and no amount of messing with it has succeeded in getting it to boot. Specifically; When I power it on, I can hear the fan spin up then slow down, it makes the normal beeps but it never actually starts. That is, the screen never gets a signal. It's not the backlight, because if it was I'd be able to see something dimly (I've had back lights go on me before). I just doesn't get a signal. I've tried stripping the system down; removed all but one DIMM (I've got four hear and I tried different ones), I pulled the HDD, DVD, NIC and battery and still I could get nothing. I did get it to boot once, long enough to run a final backup, but when I tried to restart it I got nothing again.  I just got this thing... Please tell me I didn't just throw away $650.

A couple weeks ago following a Windows update (may or may not be related), my Toshiba Satellite L675 failed to boot up. After trying a few dozen times to reboot (and a lot of simple/ineffective internet troubleshooting), I let it sit for a number of hours, after which it booted up and I could find nothing wrong. But after powering down, it failed to boot again until the next day, again after trying to boot it a few dozen times. Before powering down, I did a restore to before the Windows update initiated, so the update doesn't seem to have been the problem.
What happens: When I push power, the machine powers up, the disk drive powers up and the wi-fi light comes on, but it won't boot. Nothing else happens. I have to hold down the power button to power down again.
The next time it finally booted up, following the advice of a Bleeping Computer mod, I moved a lot of my files to an external storage drive to increase the free space to over 25% (currently its over 50%). This got it to start booting again. He also checked out my system and said there are reasons to believe I may have an infected machine, and to bring my problem here.
After about a week of booting up properly, my computer has gone back to not booting up again. It takes so many tries and only boots up about once a day.
Thanks in advance for any help you can offer!

Hi there,

Recently, my computer has been very strange... I have been having unwitnessed BSODs (showing up in the reliability monitor), lots of hardware errors in the reliability monitor and multiple programs stopping working. The troubleshooting steps I took to try to solve these issues were: updating all drivers, testing ram with memtest86+ (8 passes OK), testing the hard drive with Sea Tools (all ok) and refreshing windows 10.

A couple of days ago, I experienced my start menu, Cortana all ?apps? etc. not working. So, I logged off, only to find a black screen with a curser! The only way to turn off was to do a hard shut down. After turning back on again, I got the usual windows start up screen and normal ?AVG watchdog starting up? text (see attachment). However, my computer freezes at this stage. AVG stops at ??finished? and the computer freezes!

After trying to boot into safe mode, I simply get the black screen and curser again.

Luckily, I have all files backed up and other computers to use, but I am really concerned about the root cause of my problems as I have had similar errors in previous installs of windows.

Would these problems be caused by hardware? I am happy to clean install if necessary? but I would like to find out the causes of my problems first.

Thank you very much for your help.

Hey guys,
I own a Toshiba U500, bought it some months ago. Lately, it's been randomly crashing, and now, whenever I try to boot it up, Windows stops at the flag loading scene. Safe mode works perfectly, and I have tried startup repairing without success. I have also tried repeating the process from the installation DVD and it has failed as well. The last thing I tried was restoring the system to an earlier state (four days before), but it didn't work either. Any ideas?
Thank you all in advance.
These are the computer specs:
Windows 7 Home Premium 64bit

Intel HD Graphics (not useful here, but whatever)
I have NOD32 v4 installed, but I don't think it's a virus issue, since I haven't installed or downloaded anything new lately.

wht should i do???? could it be a power supply issue?? and shud i try removing the small coin like battery and if i shud,then wht happens when i remove that battery and how long is it to be removed for?

Answer:PC stopped booting up, no display output

What power supply is it? (company, model, wattage,)

Most low quality power supplies will have little or no transient filter, which filter the incoming AC power and suppresses any voltage spikes. Most of the time when the power is cut the voltage spikes a bit.

Try removing your CMOS battery and you suggested and leave it out for about 10 minutes, and make sure you psu is unplugged and discharged.

You can discharge it by pushing the power button immediately after you unplug it, the lights and fans should flash for a second, then go off.

I've run up an oddball problem that is stretching my sanity awfully thin.  I recently bought a 300gb Seagate HD.  I decided to make this into a boot drive.  My comp is a Dell Dimension 8200.  I'm not sure exactly what sort of MB it's packing, but someone over on the Dell forums said that with the latest bios it shouldn't matter what size the drive is.  Sure enough, after installing the drive and going into the bios, it detected a 300gb Hard Drive with no apparent problems.That said...I booted to my Windows XP Professional SP2 disc, and let it format the disc and install windows.  Every time it went to boot to the newly installed Windows XP, it would load the bios and then just stop.  (yes, the boot order was Floppy--->Hard Disk--->CD Rom, so that's not the issue).  My comp HAD been trying to load the Intel Boot Agent about the time it would stop, so I uninstalled that using the Boot Agent command prompt software that I downloaded from Intel.  After disabling that stupid thing, I rebooted, checked the bios, sure enough, it detected the drive just fine, 300gb, no problems.  And this time when it went to boot up it said "DISK READ ERROR, CTRL-ALT-DEL to restart"That got me thinking about whether the XP Pro SP2 disc was having trouble formatting the drive.  So I booted to a Symantec Parition Magic disk instead.  When it examined the partition, it found all sorts of errors, which I instructed it to fix by ...

Answer:Boot drive stopped booting...

OK... a couple things I didn't see in your story... But you probably left out because it was obvious, but I thought I'd ask if when you're swapping disks, are you going into the bios and refreshing it with the latest update?  Also, I was thinking... when you first installed windows on your 300 Gig, you said you installed it from within windows of the other disk... That could possibly cause a problem there.. depending on whether you had made XP the root drive.  Best thing to do is leave both disks attached, refresh and save the bios so it knows which disk is where... then just modify your boot.ini to give you a choice when you boot the system... then you wouldn't have to swap anything.  On the other hand, you said you had it in an enclosure... Was this because you wanted to keep it mobile?  Enclosures are sooo much slower than IDE, it really isn't worth it.

If you have Vista DVD, try to boot from DVD and performed system restore or if it fails you can do manual system restore by renaming the 5 files ( system, software, config, sam and security ) to e.g, sam.old in c:\windows\system32\config. Once you renamed those file try to copy those files from c:\windows\system32\config\regback to c:\windows\system32\config. You have to do a mual system restore by booting from Vista DVD -> Repair your computer -> Command prompt.

I have Win 7 on drive C: and windows xp on drive E: which in windows XP environment it is shown as drive C: again(I have two HDDs, 500GB each).

So as you can predict I tried using the dual booting and followed the tutorial for that on the website, I wasn't able to get it to work exactly and each time I had to change the bios settings to boot either win 7 or win XP,

I downloaded easyBCD and was trying to get it to work but my silly mistake was I Reset BCD configuration under BCD backup/repair tab and ever since I haven't been able to load windows 7 and the laptop directly loads windows xp.

I ran easyBCD in windows xp and tried to fix the problem by adding the bootloader for windows 7 there but nothing seems to work.

I am really stuck and I can not reinstall windows 7 because it is set up with all the softwares for my work

Answer:Issue booting Win 7, booting directly into XP & no boot manager

It sounds like you have the OS's installed on two separate HD's, and were booting them correctly via the BIOS - setting preferred one first to boot in BIOS setup, then booting the other one using the one-time BIOS Boot menu key.

To restart Win7 unplug all other HD's, Mark the 100mb System Reserved (preferred) or Win7 Partition Active then run Startup Repair - Run 3 Separate Times.

Once Win7 starts, plug back in the XP HD and boot it using the Asus F8 one-time BIOS Boot Menu key, or install EasyBCD to Win7 to add XP on its Add OS entry tab.

Hi all, hope someone can help or advise me on what to do.
My Pro M10 has suddenly stopped booting or reaching POST.
When power switch is pressed green light comes on and stays on and thats about it, no display and not even the fan spins up. :(

Funny thing is the battery still charges and is fine.
As you know this model is well out of warranty now and i am technically minded and taken laptops apart before so i don't mind opening up my machine.

Just thought i would ask here first before i do.
Hope someone can point me in the right direction of whats wrong, have heard a rumour that the M10's have a video fault but surely this wouldnt stop the machine POST'ing still would it.

Many thanks

Answer:Satellite Pro M10 has suddenly stopped booting or reaching POST

Hi Jay,

Difficult to pin-point your problem remotely as you will appreciate, however, I would expect the notebook to either issue a series of beeps (in a long-short type of pattern) or else flash the AC led to give some clue as to the reason for the POST failure.

As a first step I would try removing/reseating the RAM modules, the Hdd and also the optical drive to see if this improves the situation. Failing this I would tend to suspect a mainboard failure.

I'm sorry, I know this is a poor thread title, but I can not be more specific.

Quick background:
I built this system a few years back. After dealing with a bad memory stick and swapping it out for new ones this has been the most stable system I have ever built - until recently.

About a month ago my computer suddenly would not start. Most of the time it would not even get to the bios - it would simply keep restarting (as I could tell by the CD-rom doing it's boot sequence spin over and over). Sometimes it would get to the windows loading screen before freezing though.

It was really random, and I worked desperately trying to figure out what was causing it but I could not seem to find the specific culprit. After a while of re-seating hardware it just randomly started working again! However, now it seems to BSOD a lot.

I wound up buying a new larger power supply (since mine was a little lower than I would have liked), but it did not seem to solve anything.

The last week or so it has been extra worse crashing multiple times per day. Some of the crashes will cause a string of crashes over and over for a bit before it'll let me get back to windows. It's very random where it happens. Tonight while playing a game a few times, a few days back a few times while just in firefox, sometimes just in different programs, or even just sitting at the desktop while I'm doing something at my desk.

I consider myself fairly knowledgeable on fixing my computers, but this has really frustrated ... Read more

Answer:Computer stopped booting, working again but now randomly crashes

Things that I have done in attempt to solve this:
Updated any drivers that were old.
Installed latest Windows updates
Defragged HD multiple times and ran check disk multiple times - nothing was ever found wrong.
Returned my memory (was manually timed with higher voltage for years and was stable) back to base safe settings.
Uninstalled all USB devices (had a weird suspicion it was an issue) and had windows re-install the drivers.
^Same with Audio Drivers^.
Removed some programs that ran in the background (one was listed in a crash dumps) - Did not help.
Ran stress tests on Video card, CPU and Memory, finding no issues.
My CPU is running quite cool (Low/Mid 60s when playing games *typoed "50"*), the case is a phenomenal cooling system.
Replaced some cables (such as IDE) in case they were faulty
Tried running the system with as few things attached to the PS (when the system would not even boot) but it did not help.

I'm just very confused since this all happened after that one day when the computer would suddenly not start. I suspect it must be a hardware issue at this point but I don't know how to decipher the crash dumps very well and I'm hoping someone here will be able to tell what item is causing this instability.

Hi Everyone,

My Satellilte U200 has stopped booting, and can not even get to the BIOS. Nothing comes on screen.

The drive LED lights up only for a moment, and then no other action. I have re-seated the drive, the memory modules, and the battery but no change. Also
tried to boot with no battery and AC power with same result.

I tested to drive on another system and its fine.

I'm starting to think the main board has malfunctioned, because if any of the above components were the issue I should still see the BIOS splash screen.

Any thoughts?


Answer:Satellite U200 has stopped booting - not possible to access BIOS

Yes it sounds like the Mainboard (or maybe CPU or another device) has failed.

You'll need to send it to an ASP for repair.

A few weeks ago I began to get an error message after waking up my Dell XPS L702X laptop. After start-up repair runs and finds no issues I was able to re-boot for a few weeks. Just after New Year’s, my laptop would not boot and I'm unable to launch in safe mode. I know there is a system image dated 12/24 and have attempted to restore the image. The process says it completes but the same issue of not being able to boot persists. I've replaced the HDD1 in my two HDD laptop (assumed it is the boot drive) and believe I've restored the system image to the new drive, but with no success, still cannot boot or launch safe mode. Is there any hope other than reinstalling from the recovery discs burned when I first got my system?

Updated the BIOS from the Toshiba Australia website yesterday which has now stopped me booting to Win 7.

There was no apparent problems with the update or flash. I can no longer get into the BIOS settings using F12 and the boot operation stops at the Win logo then the screen goes blank. Tried booting from a Win 7 disc to no avail. Even tried taking out the hard drive.

I suspect Win 7 loads because I can see num lock light come on the keyboard but I just cannot see anything on the screen. On occasions it performs a check disk operation which is visible but finds no errors. I believe a problem occurred during the flash process and I have no idea how to correct it.

Any advice would be much appreciated

Hey there.

I'm trying to sort out my mates latop. It simply stopped booting one day, when the power button was pushed the power light would illuminate, the DVD-RW would scan for a disk, and the HDD LED breifly illuminated. The screen never showed any output, remaining black.

After a call to Toshiba, I decided to take a look at the RAM. It seems that the lower slot is faulty. Both sticks of RAM work fine in the firtst slot, alowing the machine to POST and boot, as did three other sticks I tried.
None of these tested working sticks worked in the lower slot, either by them selves or with the upper slot filled.

Furthermore, unlike most RAM slot failures I've seen, instead of the slot just being 'dead' (ie memory not recognised and booting with only the working slot), it seems that the POST sequence is interrupted right after the HDD is interrogated (the working sequence is the HDD light flashes, then the monitor activates), which would lead me to believe that the post is freezing as it tries to interrogate the faulty RAM bank.

So, is there any option, other than a new mobo, that may help get this slot working again? I have already carefully cleaned it, t no effect, and does anyone have any idea why this would have happened? The laptop has a very easy life, rarely used, always stowed in it's bag, and pretty dust-free, no hard drops or shocks either. Today was the first time the RAM access panel had even been opened, this was factory fitted memory.

Hello there, occassional lurker, first time poster, hopefully someone here will be able to help

I've been setting my laptop to dual boot xp pro, and Ubuntu on a seperate partition. All was going well, until xp decided to die altogther. I don't have that error to hand, but it's gone a little further now.

Was going to install xp pro on a 3rd partition, and it started up fine. Now I can boot fine to Ubuntu, and the 2nd version of xp. However, the original xp is still having issues.

Now, when booting up, gets BSOD - bad_pool_caller. Code at the end is: 0x000000c2 (0x00000007,0x00000CD4,0x00000060,0x86F7E1FC)

Everything I've read suggests this is talking about a hardware or software conflict. However, I've not installed any new hardware. I suspect there is a software conflict between the two versions of xp, but I can't see how that can happen.

I can boot into the 1st copy of xp in safe mode, however, explorer.exe fails to start up. Tried running it in task manager to no avail.

I forgot to add - I am using GNU GBRUB to boot between the 3 operating systems.

EDIT 2: Tried it again to boot 1st xp in safe mode - new error for windows product activation - a problem is preventing windows from accurately checking the licence for this computer error code 0x800004005

I have a SONY PC (RX-580) and it is not booting on an erratic basis. The first problem was after pushing the start button, the fan starts on high speed, but no activity light and no HD light came on at all. AFter 1.5 minutes or so, I rebooted after removing the power cord for 30 seconds. This happened 8 times today. I should mention that during this time, nothing comes on screen at all. There is no opportunity to get to the CMOS settings or even to boot with a floopy. (yes this still has a floppy drive in it.) Normally, for the past several months, this problem has simply been an inconvenience and after 2 or 3 tries, the unit boots up fine and works fine all day. Today, when it failed to do this so many times, I shut it down, opened the case and proceeded to reset all cables and connections. I didn't notice any loose connections. I didn't remove ram sticks. I then rebooted and this time, I got the HD light activity for a few seconds, then the fan slowed to a normal level as like everything was going to be okay. After a few minutes, the activity light was still lit, but no flickering like something was happening.

I turned the machine off again. I should mention that each time I turned the machine off, I didn't have to hold the button in for the normal 5 seconds. It turned of immediately.

Hello. I have an issue that I need some advice on.
For the last few mornings when I turn on my computer after 6-8 plus hours of not using it, I get this message while the BIOS is booting but before Windows starts:

Overclocking Failed! Please enter setup to re-configured your system.
Press F1 to Run Setup.
Press F2 to load default values and continue.

Now I know how to simply fix this issue by resetting the BIOS and/or if necessary, temporary removing and replacing the jumper pin on the motherboard and/or if *really* necessary, temporary removal and replacement of the CMOS battery. For me, it works by simply resetting the BIOS.

To let you know since this has been happening, I have increased my RAM to 8GB. I had to make some changes to my BIOS like slight voltages increases in DRAM and the motherboard's northbridge and the memory module timings modified. I saved these BIOS changes (as a BIOS profile) to stabilize my 8GB of RAM which seems to work great -- stability issues solved. However, now I have this issue here...

What actually happens is that one the *very first* BIOS booting when powering up my computer, the BIOS does not boot and without the beep from the motherboard's POST BIOS test. My monitor is black while, yet the tower LED shows it is running. I can hear the fan in the tower running fine. I have to manually restart the computer from the reset button and then on the second BIOS boot, the BIOS loads fine, followed by this "Overclock... Read more

My inspiron one 2305 has just quit working.   On power up, the power switch glows a steady amber.  The fans come on and you can hear the HD start to spin up and run.  No video, splash screen, or anything else.  No POST beeps, either.   A possible cause was the LCD inverter, but I've just installed a new one and that did not fix the problem.  External power supply appears to be functioning normally.   I suspect the motherboard is gone.    And the warranty is long expired, of course.
Apparently this issue is a common one for the 2305 and a result of defective design on Dell's part.    Quite a few other people are experiencing the same problem.   Anyone else run across this and fixed it?

How do I fix this?

First thing to check is that thw file is actually working. So when it boots to DOS is the prompt showing C:\WINDOWS> or just C:\> :confused

If it is just the C:\> prompt then type CD\WINDOWS then hit Enter
When the prompt shows C:\WINDOWS> then type WIN and hit Enter.

Okay, I have a problem with my computer to where my OS won't boot.

This is how it starts: I have one hard drive with two partitions (C: and D I originally put an older OS on partition C:. Soon later, I put windows XP SP3 on partition D:. I left partition C: OS alone and continued to use the XP SP3 on my partition D:.

Every time I turned on my computer, it would ask me which OS would i like to use and i would always choose the XP SP3 OS. But one day, I decided to format the partition C: so I could have some more space to work with, and I knew that it would delete the OS of that partition. But once I did that, I restarted my computer and now, it says BOOTMSG (something like that) is missing. Press Ctrl+Alt+Delete to restart.

I press the corresponding buttons but it just shows that same message. I was absolutely positive that i did not touch the partition D: and now, the OS that was on it wont boot.

I do not know if its possible to switch around the partitions or not, but thats why i came here.
