Expansion-Card Problems
If an error message indicates an expansion-card problem or if an expansion
card seems to perform incorrectly or not at all, the problem could be a faulty
connection, a conflict with software or other hardware, or a faulty expansion
card.
Fill out the Diagnostics Checklist as you perform the following steps.
CAUTION: Before you perform this procedure, see "Safety First—
For You and Your Computer."
1
Run the diagnostics provided by the manufacturers of all expansion
cards installed in your computer.
NOTE: The manufacturers of many expansion cards, such as video,
network interface, and sound cards, provide diagnostics programs. If you
do not have any diagnostics for your cards, go to step 2.
Did any of the diagnostics identify a problem?
Yes. Contact the manufacturer of the card(s).
No. Go to step 2.
2 Turn off the computer and peripherals, disconnect them from their
electrical outlets, wait at least 5 seconds, and then remove the
computer cover.
3 If you have a mini tower chassis, remove the AGP card brace.
4 Ensure that each expansion card is firmly seated in its connector. If any
expansion cards are loose, reseat them.
5 Ensure that all cables are firmly connected to their corresponding
connectors on the expansion cards. If any cables appear loose,
reconnect them.
For instructions on which cables should be attached to specific
connectors on an expansion card, see the expansion card's
documentation.
6 If you have a mini tower chassis, replace the AGP card brace.
7 Replace the computer cover, reconnect the computer and peripherals
to their electrical outlets, and turn them on.
Is the system working properly?
Yes. The problem is resolved.
