Troubleshooting

79

A possible expansion card
failure has occurred.

1

Determine if a conflict exists
by removing an expansion card
(not a graphics card) and
restarting the computer (see
"Removing a PCI Card" on
page 114 and "Removing a PCI
Express Card" on page 121).

2

If the problem persists, reinstall
the card you removed, then
remove a different card and
restart the computer.

3

Repeat this process for each
expansion card installed. If the
computer starts normally,
troubleshoot the last card
removed from the computer
for resource conflicts (see
"Troubleshooting Software and
Hardware Problems in the
Microsoft Windows Vista™
Operating System" on
page 93).

4

If the problem persists, contact
Dell (see "Contacting Dell" on
page 200).
