Okay so while I play some specific older games my screen goes black the sound stops and there's a beep for the restart, the pc automaticlly restarts with a black screen, when I turn it off the turn it back on everything works fine, and it wont happen until I play those games again, it happens while I play Far cry 3, Prototype 2 and on a few more which I don't remember, I checked if it was to my gpu and my gpu is fine goes between 60-70 degrees, I have a Rx 470 and can run anything with no problem but still some games do that I've searched the net but couldn't find anything, any ides?
