The last time i got such a message was when the driver wasn't installed correctly. Especialy the catalyst are a pain in the ass updating (imho). So I would try to delete the drivers completely and reinstall them. A bit annoying but the savest way to fix the problem. And if this doesn't help it is probably a hardware problem...
