Windows 10: Computer Suddenly Stopped Booting up...

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. *Smile

Problems with Windows 10

I can't boot Windows 10 after system suddenly stopped working

On August the 7th, I have installed Windows 10 and it worked properly till August the 21st when the computer suddenly stopped working and can no longer be boot. The screen is frozen, showing only the cursor on it.

I've never had problems with that computer before, and use it for 3 years with Windows 7 professional.

Can you help solve the problem?

 

Os recovery

My windows 10 os suddenly stopped working and asked me to restart. When i did that, it no longer boots but ends up in a blue screen. Please help.

 

Mentioning most of the event related to AVG, what about if we suspect that AVG as a root cause?

 

Hi there,

That would seem very logical as I have probably had AVG on all my other installations in the past.

Is there any way that I could uninstall AVG when the computer won't boot to the desktop (e.g. can I do it via the command line?). If not, what would you suggest I do next?

Many thanks for your prompt response!

 

Try booting into safe mode which will not start up AVG, then you should be able to uninstall it from control panel.

4 Ways To Boot Into Safe Mode In Windows 10

 

Do you have any version of Windows installation disk from 7 to 10? If you did, boot the disk, when the first prompt to choose language & keyboard layout press Shift + F10, it'll bring up a Command Prompt, just type in -> notepad <- hit Enter.

Browse to open file, navigate to C:\Program Files and/or C:\Program Files (x86), find a folder related to AVG, rename or move the folder(s), exit Notepad, exit CMD, quit the setup and boot normally.

There might be some error upon boot but hopefully you can get to the desktop. Then, use AVG Remover tool for thorough cleanup. Don't forget to delete the folder(s) that renamed earlier.

 

Hi there,

Thank you both for your quick responses.

However, I cannot boot into safe mode, as I stated in my original post:

I tried to uninstall AVG via the command line, but I could not work out how to do this after many attempts. So, I thought I could boot from a linux live cd and delete the AVG files from there.

However, after trying multiple distros and disks, all of them do not boot up, they simply hang on the start up screen.

Therefore, can I conclude that there is something up with my hardware?

Thanks again. *Wink

 

Hi again!

I was being very dense about getting rid of AVG... I have now managed to rename the folder in program files.

However, now when the computer boots, instead of the AVG message freezing, I now get the Windows startup screen continuously loading!

Sorry about the quick succession of posts!

Thanks. *Smile

 

Can you do a chkdsk c: /f somehow (replace c with relevant letter).

 

Hi there,

I will run check disk tomorrow in WinRE.

Thanks for everyone's help!

 

Just in case you are not aware, it is not always C drive in the recovery environment. You will need to see which drive letter the recovery gives it.

 

That's the progress, I think Windows tries to load something from what it couldn't be found (normally the drivers), so it'll continuously do that endlessly.

Boot again the way you renamed the folder, now browse to -> ... /Windows/System32/drivers <- inside the drivers folder, find and rename the file with the names started with avg e.g. avgxxxxx.sys etc. It would be a few files to rename.

Done with that, try to boot.

 

Hi everyone,

I have now tried running chkdsk and renaming drivers.

Chkdisk said that 'windows has made corrections to the filesystem, no further action is required' however, I still am getting the continuous boot loop.

Also, after renaming all AVG related drivers, the issue still persists.

I have tried booting from multiple linux disks and windows install disks now, and all of them are not booting: they simply come up with errors or freeze on startup.

Thanks to everyone for the help *Smile

 

Soopg, are you installed in UEFI mode? if you are, try to go into bios and disable Secure boot and adjust your CSM for UEFI and Legacy. Then try to boot into one of the Windows install disks.
