Problem Description
A possible expansion
card failure has
occurred.
Suggested Resolution
Determine if a conflict exists by
1
removing an expansion card (not a
graphics card) and restarting the
computer (see "Cards" in your User's
Guide).
If the problem persists, reinstall the
2
card you removed, then remove a
different card and restart the
computer.
Repeat this process for each expansion
3
card installed. If the computer starts
normally, troubleshoot the last card
removed from the computer for
resource conflicts (see "Restoring Your
Operating System" in your User's
Guide).
If the problem persists, contact Dell
4
(see "Contacting Dell" in your User's
Guide).
