Before installing a card, see the documentation that came with the card for information on configuring the card, making internal connections, or otherwise

customizing it for your computer. If you are replacing a card, uninstall the existing driver for the card.

Installing an Expansion Card



1. Follow the procedures in Before You Begin.



2. Remove the computer cover (see Removing the Computer Cover).



CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.

NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your

computer's electronic components. You can do so by touching an unpainted metal surface on the computer.

NOTE: To upgrade to or downgrade from a dual-graphics configuration (with the graphics riser card), you will need additional parts that can be ordered

from Dell. See Contacting Dell.

CAUTION: Your computer is heavy (it has an approximate minimum weight of 55 lbs) and can be difficult to maneuver. Seek assistance before

attempting to lift, move, or tilt it; this computer requires a two-man lift. Always lift correctly to avoid injury; avoid bending over while lifting. See

your Product Information Guide for other important safety information.

CAUTION: The computer stand should be installed at all times to ensure maximum system stability. Failure to install the stand could result in the

computer tipping over, potentially resulting in bodily injury or damage to the computer.
