Removing the AGP Card
To replace the AGP card, reverse the above procedure.

expansion card, install an expansion slot cover to close the open
slot. Insert the metal slot cover in the open slot and slide the slot
cover retention latch down to secure the slot cover in place.
CAUTION: After removing an expansion card, you must replace it with a
new card or cover the open slot (for example, with a metal slot cover or
a piece of duct tape) for proper cooling of internal components during
operation.)
