It would help if you told us which version of Windows you are running.  See if any of the following applies to your situation:

Sounds like a bad monitor type set in windows or an incorrect video card. Try changing the driver to a standar super vga.

Thanks a lot guys, problem solved, instead of ringing software support for the amazing price of 29:95. I'd never think it was that easy.
