Hi! I have two problems. The first is when I try to play games (for example Far Cry 3), the screen goes black, and when it come back, i get this error: But, sometimes randomly i get BSOD (stop:0xa0000001). It's so annoying, becase i got this problem when i have 8800GT GPU, and I changed this GPU two days ago to HD 7850 (2Gb), still have the problem. Then, yesterday i changed my trashy 500W 'deer' PSU to a Chieftec (450W), nothing has changed. the necessary files are attached. Thanks in advance for your help. P.S.: Sorry for my language, I Don't speak English perfectly.
