Suggested Resolution
• If you have one memory module
installed, reinstall it and restart the
computer. For information on
reinstalling memory modules, see your
online User's Guide.
• If you have two or more memory
modules installed, remove the modules,
reinstall one module, 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 modules of the same type into
your computer.
• If the problem persists, contact Dell. For
information on contacting Dell, see
your online User's Guide.
• Determine if a conflict exists by
removing a card (not the graphics card)
and then restarting the computer.
• If the problem persists, reinstall the card
that you removed, remove a different
card, and then restart the computer.
• 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 27).
• Move each card one at a time to a
different PCI connector and restart the
computer after each move.
• If the problem persists, contact Dell. For
information on contacting Dell, see
your online User's Guide.
