Whenever my laptop goes idle or I close the lid, when I boot it up again, it shows this. When I hard reset the laptop it goes away, but it's still really annoying and I'd rather not have to hard reset it that often. The little box on the screen is my mouse, btw.
My laptop is pretty new, less than a year old. It's an Inspiron.
Any ideas how to fix?
