A couple of months ago I had a Phenom II Quad Core 3.4Ghz, I was able to game, listen to music, check videos etc. I recently changed my Phenom II to a Eight Core 3.8ghz, at this moment, when I enter a game, for example, Crysis 2 (max video setting), at the beginning my hard-drive would make weird noises & my game would freeze. Sometimes, my pc would shut down, so I bought a SSD thinking that was the problem, reinstalled windows, my game, etc. The results.. no luck, still shutting down. Could my Powersupply be the problem? Or even my motherboard?
