Reseat the memory, or replace with known good
modules.
Fatal error indicating a serious problem with the
system. Consult your system manufacturer. Before
declaring the motherboard beyond all hope,
eliminate the possibility of interference by a
malfunctioning add-in card. Remove all expansion
cards except the video adapter.
• If the beep codes are generated even when all
other expansion cards are absent, the
motherboard has a serious problem. Consult your
system manufacturer.
• If the beep codes are not generated when all
other expansion cards are absent, one of the addin cards is causing the malfunction. Insert the
cards back into the system one at a time until the
problem happens again. This will reveal the
malfunctioning add-in card.
If the system video adapter is an add-in card,
replace or reseat the video adapter. If the video
adapter is an integrated part of the system board,
the board may be faulty.
