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:
