So in the last hour my computer started shutting down for no reason. Like completely off no freezing or anything just one second its on and then its off. The first time it happened i was playing a game. Then the second time i was just browsing the internet to see if it would happen again. And the 3rd time i just turned the computer on and let it sit their to see if it happened. I have no virus's or anything like that and my computer is not overheating. Does anyone know why this could be happening now?
