Hey guys, I just bought this PC and after installing Windows 8 64bit and installing the latest drivers I've been trying to play any game from Assassin's Creed III to Metro: Last Light but after just one minute the system suddenly crashes and the monitor goes NO SIGNAL, I have to mention I've watched around 20 minutes of some of my full HD movies and there wasn't any problem, also the colors and images are fine whatsoever.
