Right so here's the problem: Sometimes my entire computer starts to act up and begins to stutter and freeze. When it starts, once every 4 seconds everything freezes up for a second, and the sound will also do a robotic noise during that freeze (louder if there's music/video playing). Also my entire computer goes into super slow mode, and doing the simplest things will take a long time. Trying to shutdown normally also takes an eternity or two. The only way to fix this is to do a hard reset. This is completely random when it happens and I can't seem to reproduce it at will. But I have noticed that it happens more often if I do something like.. closing a program or something. Just a few minutes ago I had to restart my computer because of the stutter, and it happened after I stopped playing a game on Steam. I have also noticed that this never happens if I'm playing something. I've had my suspicions, but could it be a hard drive at fault here? I can hear my hard drive "think" right when it stutters once every 4 seconds. Or perhaps something to do with power? Maybe the system thinks its bed time after closing a game, but fiddling with the power settings doesn't change anything. Been like this for a few months now but don't feel like procrastinating about this problem this morning. Would appreciate with any help. Attached DxDiag for your reading pleasure.
