Hello , I have a problem and I dont know what to do. I used to play games like far cry 2 at maximum graphic without problems and after a while i bought a flat screen monitor and installed a old game , star wars battlefront 2 . I started to play it at maximum graphic and after 1-2 mins pc shut down.I opened far cry 2 at maximum graphic and it worked just fine , for some reason the other game wich was older made the pc shut down. One day I wanted to try to play it at minimum , and after 30 mins or so pc shut down again. When i opened far cry or wow pc started to move slow after 5 mins in any game . But not on the internet or so , just in games . I scanned pc for viruses , malware, and i couldnt find anything any ideas what I could do?
