Problem Description
Memory modules are
detected, but a
memory power failure
has occurred.
A possible CPU or
motherboard failure
has occurred.
BIOS may be corrupt
or missing.
Suggested Resolution
• If two or more memory modules are
installed, remove the modules, then
reinstall one module and restart the
computer.
If the computer starts normally,
continue to install additional memory
modules (one at a time) until you
have identified a faulty module or
reinstalled all modules without error.
If only one memory module is
installed, try moving it to a different
DIMM connector and restart the
computer.
• If available, install verified working
memory of the same type into your
computer.
• If the problem persists, contact Dell
(see "Contacting Dell" on page 159).
• Replace the processor with a known
good processor. If the computer still
fails to boot, inspect the processor
socket for damage.
• If the problem persists, contact Dell
(see "Contacting Dell" on page 159).
• The computer hardware is operating
normally but the BIOS may be corrupt
or missing. Contact Dell (see
"Contacting Dell" on page 159).
