Ok, so I've done some research on my problem and it seems quite a few people have had the same problem I am having. While playing certain games(SimCity, Natural Selection 2, MechWarrior Online, others) my PC will shut down or freeze(my monitor goes black and gets the message "Monitor Going to Sleep" then my PC freezes and I have to force shut down). I have monitored my GPU temps and CPU temps and they all seem to be in the norm leading up to the malfunction. Again this only happens with certain games, I play Far Cry 3, Skyrim, Witcher 2, and other high end graphics games on max settings and they run fine. I believe I have it narrowed down to faulty GPU, or my power supply isn't large enough. Is a 800W PS enough for my PC?
