Not sure if it's the video card or what, but my friend just built a new computer, runs fine in safe mode but when booted up in norm... it works for a little bit then crashes to a gray screen sometimes blue screen comes up. He's running windows 7 and this happens after a fresh install of windows 7? is this a problem with the video driver? I mean I tried the stock drivers and even the new updated ones.. and it's still causing problems... or is this a windows 7 problem?
