so far I have gotten, among other BSOD errors, win32k.sys dxgmms1.sys several IRQL errors, system service exception and a few others I can't remember. There seems to be no related cause between what programs I am running and the crash. I was running in 64 bit, ran a registry sweep and the only issues were 64 bit related keys. I started running it in 32 bit and still had some issues. I ran the win 7 upgrade advisor, and that came back with everything passing. I even took it in to a PC repair shop and they couldn't find out what was wrong and the memory was fine, the hdd was fine, power supply was fine. Please help.
