If you are using the Catalyst Control Center, you might want to think about ditching it, and using just the driver...I had problems using it with my 9600XT and a few programs with lockups/slowdowns...I have never tried any of the "aftermarket" drivers, but have heard good things about them from Terrell and others. One thing you might want to try b4 uninstalling/reinstalling drivers is get this

utility from ATI to completely remove all drivers and apps.
***Edit***I tried to post the link for the actual utility, but it would not work...if you go to the above link and do a search for cat uninstaller, you will find what you're looking for.
