Directx, video drivers have been cleaned with cc cleaner and are up to date, tried whitelisting crysis2.exe with AVG as well as uninstalling AVG. Graphics or sound configurations make no difference. Ram checks out with memtest. I tried DMZ mode, direct connect to PC without router, neither made any difference.
I'm skeptical its the PSU or the GPU as I've had no issues, crashing or otherwise in a dozen different FPS.
ATI 5830
4G RAM
Athlon X2 245
Is it the hardware or Crysis?
