You need to be a little more specific here, that M/B came with onboard video which has to be disabled in the CMOS setup, to be able to use the AGP slot, but it sounds like you're saying, you've got an existing AGP card in the machine you can't get out, I looked at the picture of the M/B and didn't see a holdown clip at the far end of the AGP slot, that would have to be disengaged to remove the card, but if its the same color as the slot material, you may have one, but I doubt it. Have you removed the lock in screw, or is there a case rivet in the way of the AGP cards bracket coming out, check these things out.
