Memory modules are detected, but a
memory configuration or compatibility
error exists.
• Ensure that no special memory
module/memory connector placement
requirements exist (see page57).
• Verify that the memory modules that
you are installing are compatible with
your computer (see page57).
• If the problem persists, contact Dell
(see page105).
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
page60).
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
page46).
4
If the problem persists, contact Dell
(see page105).
