I would say that you haven't got the correct device driver for your video card. It sounds as though you have a generic driver since the standard VGA driver would only give you 16 or 256 colours. Whilst the Windows 2000 has a large driver library it isn't exhastive. Find out what video card you have (take the lid off and examine it closely is the best bet) then get the latest driver from its manufacturers website. This will also give the card's extra functionality. The other vital thing with Windows 2000 is to install the latest DirectX (9a I think) from Microsoft as this has a large bearing on how well games play on this corporate operating system.
