Hey, so about 3 months ago, it was the first time it happened. while playing a game(dota) the computer suddenly froze, as if its a picture, i couldnt move my mouse, hear anything from teamspeak, or talk to people in teamspeak, and i left it there for a few minutes, untill i had no choice but to manually force restart the pc. It happened about twice since then. Anyone have any idea what it is?
