I have a Toshiba Satellite with Windows 8 and recently, I've been having an issue with it want to freeze, where the mouse simply quits moving or moves very jerky and won't do anything when you click it (this is with both the external mouse and built-in mouse). I then have to shut it down and restart it, and sometimes I have to do this 2 or 3 times, before the problem goes away. I've ran Spybot, MalwareBytes, Hitman, and TDSS, and they find nothing out of the ordinary adware stuff. The only thing I haven't done is run them in safe mode, but that's because I'm not sure how to get there on Windows 8. Is this a virus? or hardware issue?
