It's a really strange problem I'm experiencing.
Occasionally (after about an hour of use), my laptop will start hanging for 10 seconds at a time, un-hanging for 1 second and updates the display with whatever happened while it was hung, then it will hang for 20 seconds and eventually it will just completely lock up and I have to shut down by power button.
The problem is that I can't reproduce this easily, because like I said, it only happens randomly after an hour of use.
I thought it might've been overheating at first, but my fan is working fine and my laptop isn't all that hot. Plus, if it was overheating, shouldn't it have a protection mechanism to automatically shut down?
I haven't installed anything as of late that would cause this, either, that I know of. Does this sound like a hardware or software problem? What could be causing this?
