video drivers causing cpu to spontaneously reboot (ati x1950)
 

I've got 3 monitors running on 2 ATI x1950 pro cards.

On occasion, my screen will blink blue (with white text but it goes away too fast to read) and then the computer restarts. I'm almost positive it's videocard related.

It doesn't matter which videocard driver I use. I've updated my chipset drivers as per ATI's suggestion but the problem persists (i'm fairly sure that it only happens when my monitors are on (i'm away from the computer usually when it happens once every 2 - 20 hours)).

I will continue discussing this with ATI's support, but I wanted to see if anyone else has experienced something similar and has any ideas.

Cheers,
Pogo

How do you know it's video-card related? It could be RAM or Harddrive or MotherBoard. (If you're even sure it's hardware. It could be a driver issue with something funky.)

You could do some stress testing of your ram. (Not that I'm so convinced it's ram, but I don't know any other tests. [img]/images/graemlins/smile.gif[/img])

Sounds like a standard Blue Screen of Death.

Check the Windows System and Application Event Logs to see if it tells you anything about the STOP error that occurred.

It could literally be anything driver related or hardware related.

Your event log should have an entry for a blue screen. It will be a bunch of letters and numers like 0x000001244b

Write that error code down. You also need to set your PC to pause during a failure. This will keep the error screen up and not reboot the PC allowing you to see what error ocurred. To do this:

Right click My computer----properties---advanced tab---click settings button under startup and recovery---uncheck "automatically restart" under system failure

what kind of PSU do you have?
