It started yesterday, I was playing TF2 and my pc crashed into a black screen. I forced shutdown it. Now, every time I try to play a game, after a few minutes or even seconds, it will change sides, the right side becomes the left side and the left side is on the right side of the monitor with a big black bar somewhere in the middle of the monitor. It also happen when I am not playing a game but randomly.

GPU: Sapphire Radeon HD 6670
Mainboard: Asus P8h77m le
Monitor: BenQ G610HDAL
