that happened to me before too

you need to right click on your desktop and uncheck tile windows vertically / tile windows horizontally

Very strange. Trying pressing the Prnt Scrn button, open Paint and press Ctrl-V. This should paste a screen shot of your desktop. Upload that image to http://tinypic.com/ or a similar service and maybe that will give us more information as to the problem.

Did you try resetting the computer?

Did you try wiggling the monitor cable and connection to the computer?
