Advanced Troubleshooting
Problem Description
Memory modules are detected, but a
memory failure has occurred.
A possible expansion card failure has
occurred.
Suggested Resolution
• If you have one memory module
installed, reinstall it (see page 64)
and restart the computer.
• If you have two or more memory
modules installed, remove the
modules, reinstall one module (see
page 64), 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 64).
• If the problem persists, contact Dell
(see page 78).
Determine if a conflict exists by
1
removing a card (not the video card)
(see page 51) and then restarting
the computer.
If the problem persists, reinstall the
2
card that you removed, remove a
different card, and then restart the
computer.
Repeat this process for each card. If
3
the computer starts normally,
troubleshoot the last card removed
from the computer for resource
conflicts (see "Resolving Software
and Hardware Incompatibilities" on
page 44).
If the problem persists, contact Dell
4
(see page 78).
