2. Unplug the computer's power cord, and then disconnect all cables from the back
of the computer.
Caution:
Wait approximately 20 seconds after unplugging the power cord before
disconnecting a peripheral cable or removing a component from the
motherboard to avoid possible damage to the motherboard.
3. Remove the cover to the computer's case.
Note: If necessary, consult the computer manual for help in removing the
cover.
Caution:
Static electricity can seriously damage computer components. Discharge
your body's static electricity by touching the power supply or the metal
surface of the computer chassis before you touch any components inside the
computer's case to avoid damaging them.
4. Unscrew or unfasten and remove any existing graphics card from the computer,
if necessary.
5. Locate the appropriate bus slot and, if necessary, remove the corresponding
metal backplate cover(s). Make sure all internal cables are clear of the slot.
Note: If you cannot find a bus slot to match the card, you need a graphics card
with the correct bus to match the motherboard.
6. Align the graphics card with the slot and press it in firmly until the card is fully
seated.
7. If your card requires supplementary power and must be connected directly to
the power supply, locate the appropriate power connector cable(s) from the
power supply and connect it (or them) to the graphics card's supplementary
power connector(s).
Note: If applicable, before installing a card that requires a supplementary
power connection, make sure your existing power supply has such a
connection available.
Tip: The location of power connections may vary between models. They can
be located on either the side or back of the card.
