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.

z If beep codes are generated when all other expansion

cards are absent, consult your system manufacturer’s

technical support.

z 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 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.
