Memory modules are detected, but a
memory failure has occurred.
• If you have one memory module
installed, reinstall it (see page 75)
and restart the computer.
• If you have two or more memory
modules installed, remove the
modules, reinstall one module
see page 75), and then restart the
computer. If the computer starts
normally, reinstall an additional
module. Continue until you have
identified a faulty module or
reinstalled all modules without
error.
• If available, install properly
working memory of the same
type into your computer (see
page 75).
• If the problem persists, contact
Dell (see page 90).
A possible expansion card failure has
occurred.
1
Determine if a conflict exists by
removing a card (not the video
card) (see page 62) and then
restarting the computer.
2
If the problem persists, reinstall
the card that you removed,
remove a different card, and then
restart the computer.
3
Repeat this process for each card.
If the computer starts normally,
troubleshoot the last card
removed from the computer for
resource conflicts (see "Resolving
Software and Hardware
Incompatibilities" on page 49).
4
If the problem persists, contact
Dell (see page 90).
