Reset the memory, or replace with known good modules.

4-7, 9-11

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 due to a malfunctioning add-in card. Remove all expansion

cards, except the video adapter.

• If beep codes are generated 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 card.

If the system video adapter is an add-in card, replace or reset the video adapter. If the

video adapter is an integrated part of the system board, the board may be faulty.

Note: If Motherboard beeps fast for approximately two seconds (~20 beeps) and then turns off, then

Jumper (J37) is missing, meaning that “Load Default BIOS Settings” function is enabled until J37 is

back in place.
