Suddenly cannot play games on Radeon HD 6850
Alright, this is a somewhat long story, but I feel that all of this information may be relevant to the problem. The events are listed in chronological order.
1. Everything is fine. I have no problems with anything.
2. I buy Magicka, a game on Steam, at the behest of a friend.
3. We play for 6 hours straight, no problems.
4. I turn off my computer.
5. The next day, I update AMD Vision Control Center to version 11.8.
6. I don't play anything that day but I experience strange graphical errors. My memory is a little foggy, but I'm 75% sure that this as after I had updated.
7. Errors included a strange screen flickering that I can only describe as a constant screen tearing effect on my desktop. Then there was this odd mirroring effect. It was like my screen was split down the middle and then swapped. My screen also went black randomly twice, at which point I had to hard shutdown do to unresponsiveness. Upon restarting my computer both times, Windows detected nothing wrong. No error messages, nothing.
8. The Problems seemed to stop abruptly.
9. Tried to play Magicka the next day.
10. Played for 2 minutes before the screen went all black or white and my entire system locked up.
11. Tried to play several times and each time I met with the same results.
12. Reinstalled Magicka. Problem Persists.
13. Reinstalled Graphics Card. Problem persists.
14. Reinstalled Steam. Problem Persists.
15. Attempted to play another game to check the scope of the problem. I loaded up Portal 2 and at the end of the camera tutorial where the player is prompted to sleep, my screen went black and the sound started skipping. Mind you, I've played the game to completion with absolutely no problems before.
Now I'm completely stumped. Please, any and all help is very much appreciated, I can provide a dxdiag if it would be beneficial in any way.
