I'm constantly getting blue screens and all my games are crashing after a fresh format to windows 7. I was getting the same thing on vista 64-bit too before I formatted. This didn't happen when I first built my machine last summer so I'm assuming it is a driver issue.(?) The most recent blue screens have been from dxgmms1.sys. Would going to older video card drivers help? I'm using the absolute latest and flashed my bios to the latest.
