Hi, I'm trying to install a Nvidia GeForce4 MX 420 64mb AGP graphics card. The psu is quite new, (550w I think). Firstly I tried to install the driver but it would not let me do this until the card had been put in. When I installed the card and plugged monitor into it I could boot into bios ok but no display as windows xp was loading (only once could I see it faintly). Also it appears windows does not load properly when card is inserted. In bios the display is set to AGP. Can anyone help?

This may mean the card is faulty. Where's it come from?

It did come from a working machine following upgrade. However someone did tell me there are 2 different types of agp cards are not all are compatible. The card is older than the motherboard I'm putting it into. Is thia not good?

Depends.
If a board requires a certain AGP voltage to work properly, the AGP slot itself is keyed. You wouldn't be able to insert a non-compatible card in, but that won't stop you shoving a non-working card in that fits. All AGP slots are backwards compatible so they can run older cards if needs be.


Here's a webpage about AGP Voltages and you'll see what I mean about keying:
