So I dont know at which forum section I should ask this so I ask it here. So I was playing Just Cause 2 and I accidently hit my PC and it froze. This happens often when im on my PC, when I move around my chair and stuff I accidently hit it from time to time, when the PC is on but it never froze before, normally nothing happens and the PC keeps working like it should.. Can this be because something is loose in my PC? I vacumed it like a week ago and everything seemed normal inside the case, so can this be caused by something else??? I really wanna know the problem so I can prevent it from happening again.
