Well for those having problems with anything, this is how I happened to get rid of it..
When shutting down, normally you would click on the arrow in the start menu, select shutdown.
This time, try the big "power button" which only puts it to sleep. When it's in that mode, move your mouse or whatever to get the thing back to life.
Try shutting down again.
This sounds stupid, I know, but sometimes lucky is better than good.
