What graphics card is installed in your Dell Dimension? I checked on the Dell support site but there are quite a few...

The only thing I can recommend is that the computer is kept in a well ventilated area to keep cool, and that the latest drivers have been installed.

One more thing to check is to see when this started happening, and if there had been any hardware/software updates (including windowsupdate) that may have caused this
