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 beep codes are generated even when all other
expansion cards are absent, consult your
system manufacturer's technical support.
- If 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.
