Well my system specs are in my profile but I'll put them here for simplicity sake as well. Asus P5N-T Deluxe Q6600 @ 3.0 Vcore 1.20v 2 x 2GB Corsair Dominator RAM @ 1066 2 x 8800GT stock Razer Barracuda AC-1 750watt Corsair PSU 3 HDDs and DVD drive Okay before you go and say its my overclocked CPU its been oced for months now and the problem has only recently just started. It usually happens when I'm playing a game of some sort but at random times, I played CSS for a good 3 hours then it reboot, other time less than an hour. It has happened most recently when I booted up FEAR 2 and I was was tweaking the games settings, after I had it setup just right and clicked New Game, system reboots. Any thoughts?
