On a more serious note: very strange graphical problem. First uninstall the drivers, reboot and then install the drivers again. This is to make sure that there is no strange setting in the graphics card and that the drivers are properly installed.

After that see if some program running in the background might be causing it. For example anti-virus, desktop enhancment, messenger. Turn them all off and run again.

Also, what graphics card do you have?
