White square on my desktop

[keithh]

I have suddenly got a 2cm x 2cm white square on my blue W2000 desktop and can't get rid of it. Has anyone any idea what has caused it and how to get rid of it?

Check what's in settings of your dekstop -- Ctrl-click on dekstop, choose Properties -> choose Desktop tab and set picture to None if any other's selected

Just lower mac OS resolution, it is Video card problems, it cannot handle high resolution, or too hot
