Troubleshooting POST BIOS Beep Codes
Number of Beeps Description
1,3 Reseat the memory, or replace with known good modules.
6,7 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.
q If beep codes are generated when all other expansion cards are absent,
consult your system manufacturer’s technical support.
q 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.
8 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.
