Suddenly getting low FPS

A week ago I was messing around with my AMD Catalyst control center trying to get a good preset to make a game look better. After I did this, every game I tried to run (no matter how demanding it is) seemed to run at low FPS/lagged. I've tried to restore the factory settings in the Catalyst but that doesn't seem to help. I've tried reinstalling my graphics drivers but that doesn't help either.

Specs:
Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz
AMD Radeon HD 6800 Series
8.2 GB RAM
Microsoft Windows 7 Home Premium Edition Service Pack 1 (build 7601), 64-bit

Any help is appreciated :)
