Hello,

 

This is really urgent for me...

I ran into a new problem on an old computer.

And I'm having trouble fixing it because my XP PC keeps throwing me a BSOD with error codes:

 

STOP: 0x00000050 and randomly (0xEE70F000; 0x8058AF5D; 0xEE92F000; 0xEE9B2000; 0x00000001; 0x00000000).

 

It happened after this sequence of actions:

 

I had Comodo Internet Security and it was slowing down my PC a bit so I had decided to install Avast antivirus and ZoneAlarm Firewall combo instead. I updated Comodo and scanned my PC for any malware, none was detected. Then I uninstalled it but didn't restart my PC; installed ZoneAlarm and Avast, and only then I rebooted.

 

Windows loaded but right away I got an error and a blue screen with above mentioned error codes.

 

I've tried F8 and it only shows me options for boot-up, like from which disc to boot, there is NO SAFE MODE option.

 

And now I'm stuck. I cannot start the PC... As soon as the programs start loading, the BSOD comes.

 

 

WHAT CAN I DO ?

This will only work if you have system restore turned on and it only does a partial system restore but it may get you back to before you installed avast and Zonealarm. Follow the steps in this link.

Thank you for a quick reply and the link, I'll try whatever I can.

 

***Yeah, I don't think I had the restore option turned on...***

 

 

I managed to win some time - when it booted I killed explorer.exe thru Task Manager and the BSOD didn't appear but how is it possible to uninstall any program without Explorer running?

What happens when you restart explorer in Task Manager?

If you do not have system restore on the only thing I can think of is to download Kaspersky Rescue Disk and use the offline registry editor to delete any avast or zone alarm reference in the following keys. That may let you boot.

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Edit: fixed Kaspersky Download link

Thanks SO MUCH.

 

It seems to have worked.

 

Deleted Avast registry entries with Kaspersky RD but 3 Avast processes somehow still loaded.

Uninstall leftovers with Advanced Uninstaller Pro, yet can't get rid of AvastSvc.exe and AvastUI.exe.

Anyway, phew, Windows started without any errors. Not sure if will be downloading an earlier version of Avast that supposingly doesn't cause BSODs...

 

BTW, ZA firewall was OK, left it in place.

(Damn, I'm so sick of fixing my PCs over the years I'm already considering a Mac that could simply let do my job without making me involuntarily become a PC fixing expert... These forums constantly save from inevitable PC-doomsday.)

Thanks for the feedback. You might be able to delete AvastSvc.exe and AvastUI.exe in safe mode or offline using a linux distro. Unlocker may also work. You can delete any avast services by Running AutoRuns.

 

I have read that avast and ZA do not play together very well.

 

Edit: another option is to download the avast uninstall utility. It may remove some of the pieces left behind. Run in safe mode.

Thanks once again for much useful information.

No option for accessing Safe mode, however. Will try other suggested methods.

I've tried F8 and it only shows me options for boot-up, like from which disc to boot, there is NO SAFE MODE option.

 

When the disk boot options appear when you press F8 hit Esc and immediately start tapping F8. Does this work?
