Just had a doozy of wacko computer issues - really have to get new one soon. First, the screen just went black and shut off the computer - not the usual thing it does every couple of weeks. It restarted by itself, which it's never done. Fine. Everything comes back but the mouse and keypad aren't working, so I hard-wired them into the computer. Blue Tooth would not recognize them or my speakers. I finally shut down the computer properly and restarted and now it's back to normal - this stuff is wayyyyy to scary.
