Don't matter what I'm doing it always locks up, if I'm using the computer it will lockup about 2 hours later, but if it's just on and not in use it will lockup within a hour or so ..right before it locks up I hear a click from inside the case and boom a sec later it locks and I can't do anything..I have all Microsoft update , this even happens on a very fresh install like 1 hour after install it locks up. I have no idea on how to tell if it's a hardware issue so I can't do anything there.. Please HELP
