Hey, so lately I have been having some issues with all my games. You see a few months ago my computer crashed while playing crysis 2 and the screen never showed any picture while the computer was on, so I went to my local computer shop to get it looked at and upgraded(I thought it was time for an upgrade anyway)I took it home thinking it was all good until I tried playing crysis 2 again. It crashed, well not the computer but the screen goes into power saving mode and I cant turn it back on until I restart the computer. The computer shop ran all the tests and everythings fine, its not overheating or anything they dont think, although the first time I took it back(yes I have had to take it back about 3 or 4 times, I even tried a different shop) there was a cord jammed in one of the fans, but they replaced that. I really need help here, its been like this for 5 months now. I really dont know. Its usually when I play some of my more “hardcore games” like crysis1&2, section 8, brink etc, it doesnt have a specific time when it crashes(screen goes into power saving mode) its just random. I can play a game for days without anything happening and then BOOM!, CRASH!. I dont know if I have a faulty GPU, CPU, motherboard or whatever, what are the symptoms for that? Anyway really need help here, I am desperate so if any of you compiter gurus have any ideas of siggestion on what I can do please tell me!
Thanks
