So I'm not sure exactly how to describe what is happening. I built this computer myself. (Don't think listing the parts is necessary for this problem/solution)
Basically, I'll be browsing the net, or even just doing homework on word or excel, and the computer will start to act funky. First it will freeze, from 5 - 30 seconds, mouse doesn't move, can't ctrl alt dlt, can't alt f4, nothin. When things snap back out of freeze mode, sometimes the mouse icon gets all funky, like normally if a hyperlink is hovered over it turns into a hand right? well it'll be a I cursor or it might be an old school looking hand that's all 8 bit.
It will freeze again, and usually the 2nd time it wont come undone and I usually reset my computer at this point.
