Aright so , until a week ago my asus g75vw was working just fine, then i installed saints row 4 and it was working good, until 2 hours into the game it crashed fully, it just shut off in an instance. I tried turning it on and it shut down emediately after turn on. then again and it worked. What's happening? I read there is a thing in some computers at will make them shut-down if they overheat but mine didn't overheat at all. Thanks for helping.
