But I have updated the drivers since then, and now it seems worse. I just opened up the performance tab, I didn't even get to see the settings load before it crashed. I get a quick BSOD flash and then a reboot. It reboots back up without any problems then within a few minutes it reboots again. I have started in safe mode with network enabled and it hasn't given me any problems. I am not sure what I did last time to fix the problem. I just remembered I shouldn't go anywhere near the performance settings. Just like this time, simply clicking on the tab to view the settings crashed the computer. But last time the crash only happened when I clicked that tab. Now it seems to crash within a few minutes after restarting the computer. I can get in and open a program but it crashes pretty quick. I have attached the DXDiag report that i just ran from safe mode. I can provide any other info you need to help me get this fixed! I would say I am an expert user. This is probably the 10th computer i have built from parts. It runs so well as long as this stupid thing isn't messing it up. Sometimes i get a few green artifacts when running games (L4D, HL2, Crysis, FarCry, COD4). It doesn't affect the game play but they are noticeable. This system runs all of those games on max settings at 1680x1050 (except Crysis) If you have any ideas please help me out! I need my computer back! *Update* add screen freezing to the list of problems. It will either freeze or restart. I have tried to uninstall all the nvidia stuff in safe mode, but I keep getting "1628: Failed to complete installation Install" I cant uninstall the nvidia stuff, so every time i restart it keeps rebooting. GAH!
