Crashing randomly with Windows 7

[MrMaggot]

I just recently updated my computer from Vista 32 bit to the 90 day trial for windows 7 64 bit (since the computer came factory installed with a 32 bit OS). My wife and I enjoyed playing Mario Party 6 while i was running vista but were having problems with framerate which is why I wanted to upgrade. Since the upgrade, the framerate did increase but now I am experiencing random crashes within about 5 min. I never had this problem before with vista. I tried a few other games and same issue. I have tried everything I can think of and am completely out of ideas. Any ideas from anyone else?

hmm, which version of Catalyst driver do you have installed?

[MrMaggot]

Forgot to mention the builds. I am using build 3661 but I have tried several other builds and have had the same problem. I'm using version 9.9 of the catalyst suite.

There is your problem
Downgrade to 9.3, i believe
There is a memory leak
