I know people had to post something like this before, but I am having shut down problems when I play games. The other day I just bought graw2, it would just shut down after a couple mins playing. I downloaded crysis to see if it was a heating issue. I played through crysis with no problem. Only when I played graw2 did it shut down. I played crysis in 32bit mode it shut down. Now today for some reason crysis 64bit version shuts down on me. I don't think its my power supply I just bout a pc power and cooling psu 850watt one. I haven't had it longer than a week I think. I flashed my bios to a recent revision and I still have the problem. My rig consists: evga 680i sli, 8800gtx bfg, 2 gigs of cosair dominator ram, 850watt pc power and cooling, plextor dvd-rw(px-755sa) 6600 core 2 duo. It might be a software issue cause it played crysis fine the other day but didnt play graw2 longer than a couple of mins. If anyone can help I would appreciate it. I know others had shut down problems but I haven't heard a problem like this.
