Hi,Check for your Display card drivers and verify that there sholdnt be any yellow mark - Start -> Settings -> Control panel -> System -> hardware -> Device Manager. If you have yellow mark next to display adaptor, try re-install your display drivers else Check your computer resolution and color quality from Click Start -> Settings -> Control panel -> Display -> Settings.Hope this helps.

Hi, · Is this the issue on the desktop or when you using any particular application?· Were there any changes made to the computer before the issue occurred?· Who is the computer manufacturer?· Have you tried to change the screen resolution as suggested by Saurabh? You may update the drivers for the display card from the manufacturer’s website and check if that helps. You may check if the same issue persists when you boot to the desktop in safe mode. To boot in safe mode follow the link given below.http://windows.microsoft.com/en-US/windows-vista/Start-your-computer-in-safe-mode Hope this information is helpful.Amrita MMicrosoft Answers Support EngineerVisit our Microsoft Answers Feedback Forum and let us know what you think.
