As the title states, when I'm playing a more demanding title (most often MWII) my PC will essentially shut itself off. Both monitors go black, no sound, and the VGA EZ Debug light on my motherboard turns on. Turning the PC off and back on fixes it temporarily. The VGA debug light doesn't return until it happens again.
I've tried everything I can think of at this point, reapplying thermal paste to my CPU cooler, reseating my GPU, changing my PSU cables, uninstalling and reinstalling all AMD drivers, updating BIOS, resetting the CMOS battery. The problem still persists.
My specs are:
RMx 850 Gold
2x8 GB Ram
