Add on to-Grpahics Card

I've just tried the card on a tv(as the card supports TV out)and it works, it only doesnt work when I hook a monitor on to it. Rich

Well, don't start to get involved with drivers etc just yet. when the PC boots before windows actually starts you should get the bios display which any graphics card should display without any drivers loaded.
You don't say what the original graphics card is but if it is an onboard graphic card you probably have to go in the bios and set the onboard graphics to be off or disabled or whatever and also set the graphics to use PCI or AGP depending on which version of the MX 4000 you have installed.
