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.
