Advanced Troubleshooting 55
No memory modules
are detected.
• Reinstall all memory modules (see page 83)
and restart the computer.
• To eliminate the possibility of a faulty
memory connector, remove all memory
modules, reinstall one memory module (if
the computer supports a single module) (see
page 83), and then restart the computer. If
the computer starts normally, move the
memory module to a different connector and
restart the computer. Continue until you
have identified a faulty connector or
reinstalled all modules without error.
• If the problem persists, contact Dell (see
page 100).
A PCI bus failure has
occurred.
1 Determine if a conflict exists by removing a
card (see page 75) and then restarting the
computer.
2 If the problem persists, reinstall the card that
you removed (see page 75), 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 63).
4 If the problem persists, contact Dell (see
page 100).
A video controller
failure has occurred.
Contact Dell (see page 100).
Other failure has
occurred.
• Ensure that the cables are properly
connected from the hard drive, CD drive,
and DVD drive to the system board (see
page 74).
• If the problem persists, contact Dell (see
page 100).
