Is there a tuning fork in your monitor settings? click it, this should solve the problem. Also check how long you have the screen saver configured for. I'd suspect too long, 10 minutes at most. It must refresh occasionally or it will cook your monitor

Im having problems with my pc running in vista. Whenever I move an open window across the desktop, the sides of my desktop apears to have waves that follows where I move the open window. i already tried to update my video card driver but nothing changes. Please help me because it's very annoying.
