Same thing happened to me last week it lasted for about 4 days all I did was kept closing the pop up windows which was about every 3 minutes. All the icons at the bottom of my computer were different. I didn't do anything to try and fix it because I didn't know what to do and the way it come it went. My computer is fine now. This is the 3rd thread on the board with the same computer problem. I wonder what is going on.
