Any help with this issue would be great. I have a evga gts250, core i7 920, 6gb OCZ ram, pc power and cooling power supply, and a creative sound card and am running vista x64. The issue is after about 20 minutes of game play I get "Display Driver nvlddmkm Stopped Responding and Has Recovered". I have tried multiple driver and the temps under load are about 65....Thanks in advance.
