Memory modules are detected, but a
memory configuration or compatibility
error exists.
• Ensure that no special memory
module/memory connector placement

• Verify that the memory modules that
you are installing are compatible with
your computer (see page 52).
• If the problem persists, contact Dell
(see page 91).
A possible expansion card failure has
occurred.
1
Determine if a conflict exists by
removing a card (not a graphics card)
and restarting the computer (see
page 55).
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 42).
4
If the problem persists, contact Dell
(see page 91).
