Do a system file check SFC /SCANNOW Command - System File Checker
Update your Nvidia driver
Drivers - Download NVIDIA Drivers

I already had the latest nvidia driver but I downloaded it again and did a clean install. Didn't work.

Did SFC with no problems.

Decided that I was coming up on close to 2 years without a crash and decided that I couldn't complain. So I wiped my HD and did a clean install of 7ult. I had gathered a lot of useless crap over that time, so I was due a clean install anyway.

thanks for the tips though!
