Sorry to hear this. I looked at your system info via Free-DC. System info notes ATI Driver version
1.4.1741. That number correlates to Catalyst 12.6 Beta. I would suggest uninstalling the Beta driver and install 12.6 certified (

If you prefer the latest driver, version 13.1 x64, it can be DL'd (

Or any of the older x64 versions can be had (

I would recommend running Driver Sweeper 3.2.0 (

after uninstalling old drivers. And for added insurance run CCleaner (
