My computer monitor turns off or turns off completely randomly whenever I play games. It never happened before until now. I believe that my pc did infected with a virus/malware but I did system restore, which supposedly erased the virus, but I am no sure if the virus is still on my comp. However, I did play some graphic intensive games such as Red Alert 3 and Starcraft 2 and I think this problem happened first when I was playing either of these games. I am not sure what is going on here, can someone help me please?
