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 add-in 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.
