This should solve the problem and you can back up your data before formatting. That is what I did.|||run a virus/spyware check. spyware probably deleted your option in your display properties. i had a problem like this where my wallpaper stayed %26quot;run a virus scan%26quot; and when i went to change, i noticed the wallpaper tab and screensaver were removed. id wait till someone answers with a more educated answer, so this is a bump! because my resolution was just recovering the system.
