video drivers causing cpu to spontaneously reboot (ati x1950)

[Pog0]

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
