HL2 Problem

Everytime I play Half Life 2, i will be playing for about 10-15 minutes then the game will crash and the computer will restart... its not an overheating issue and i know that for sure. Also, i can play other games endlessly. I also have the newest drivers. The game doesnt do this on my ATI 9800Pro, but now im using my new computer...
AMD 64 3500+
Soltek KT800-Pro 939
eVga Nvidia 6800Gt
1gb Crucial Ballistix Tracers
2 80gb HDD on RAID 0, additional 80gb for storage
520W PSU

I dont really know the problem... I have XP Pro and the game is running at 1280x1024. Thanks.
