Hello, I have problem while palying game like World in conflict, Counter strike source. Sometime got error msg that video driver stop responding and recover (cont playing fine at this point), sometime got black screen of death and need switch of power It only happen when I play game and I'm not OCed. My system CPU: Intel E8400 Motherboard: ASus Maximus fomula Ram Speed, size and #sticks: 2x1 GB PC 6400, cas 4-4-4-15 (OCZ sli) GPU: Gigabyte GV-NX88T512HP (8800GT) PSU (do not leave this out): Cooler Master M620 (620W) OS: Window Vista Utima I run memtest w/o an error, run othos prime all day w/o any problem, like I said it never crash while I'm not playing game so I think it's not CPU, RAM problem. So I think it's my video card or PSU problem. Please check my minidumb, Thank in advance. PS: sorry about my english.
