I have ABOUT the same card and upgraded the same as you (except x64 to x64) It gave me a BSOD ann I had to start in safe mode, and install the newest driver for Vista from there. It now works fine....it's only been 3 minutes though. I would try that I guess. Worked for me.

I have a 9500 GT and had the driver on a CD. Just to clarify. It's working great now....

I really hope this helps you. I just went through the same issue.
