Solved: Fatal system error

Windows xp home. Custom built. Had it for 3 yrs. Just recently I went to shut dowm my pc. It locked up and wouldn't shut down. I had to hit the reset which I hate to do and on start up it got to the screen where it says windows is starting up then the screen goes blank and an error pops up : STOP : COOOO21A Fatal system error. Windows login process system process terminated unexpectedly with a status of 0xC0000005 sytem has been shut down. (0x00000000) Then after this error it keeps repeating by Windows trying to load. Please help. Thanks, B-72

 

Well first thing I can think of is, try to reboot, but when you get to the System screen press f8 and boot to safe mode.

 

This site may help you troubleshoot it.

ok I got in using safe mode. Anything I can do or check? Thanks.

 

Your best bet would be to read and follow the instructions of the link I posted. If that doesn't work just let me know.

 

A lot of it is "Greek to me" and kinda over my head in detail. Should I try that Dr. Watson First ? Thanks for your patience.

 

I just tried to restore to an earlier time {1 week} which was sucessful but "fatal system error still happens. On start up, I noticed, that gigabyte has an F9 option : Express recovery if that would be of any help to us.

 

I tried booting to last known good config. Same results.

No new software or hardware.

 

Also just before this problem happened, I had no sound, and still don't.

 

What about running eventvwr.msc ?
