It is now time to put the AGP card into the slot. To do this, align the AGP card directly over the slot in the motherboard. Gently press down on both the front and back of the card simultaneously to push the card down into the slot. Once the card is seated in the slot, screw or fasten down the card to the case at the PC card slot.
Some AGP cards required additional power from the computer's power supply. This is provided through a 4-pin Molex power connector. If your card requires this, find a free power connector and plug it into the card.
