Got a 3000+xp, its running at 38-40c...so I'm sure its not a heat issue there. Vid card is a 9800Pro, it gets a little toasty after playing a game or something, but I can still touch it just fine...nothing too hot. Mobo is an Asus a7v8x-x... It doesn't really ever happen on the desktop, but when I load up something like Battlefield:vietnam, it reboots EVERY time within 10-20 minutes of playing. I can't really think of anything it could be aside from the vid card...I put in a nvidia 5600fx for a little while and it didnt reboot, I played for quite a while...so its gotta be the card. Any suggestions on how to fix it? Maybe its just a bad card? Thoughts?
