Media Center does not start normally, everthing else on my compter works fine. When I open it I can hear the audio and see my mouse. The menu is just a black screen though. The bottons (My Videos, My Music, ect.) are still there eventhough I can't see them. The only thing I can see is the Help screen when I hit F1, but in the help menu when a dialoge box appears in the bottom right corner its solid blue so I can't see that either. When I uninstall the ATI driver I can open Media Center and see the menu like normal (in low res). When I reinstall the drivers its back to the black screen. I've tried every driver from June until now and nothing works.
Now just to make sure that it wasn't a problem with Media Center I put an old NVidia card in and everything worked fine.
