Some graphics cards require either one or two booster cables connecting the card to the auxillary power connectors on the logic board.

The graphics card NVIDIA GeForce 8800 GT requires one booster cable; the graphics card NVIDIA Quadro FX 5600 requires two booster cables.

Disconnect the booster cable(s) from the logic board.

Release the small locking clip at the front of the card’s logic board connector by pushing the clip up toward the media shelf.

Holding the card by the top corners, gently pull up the card and remove it from its expansion slot.

If you are replacing a booster cable with a new one, disconnect the cable from the card.
