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.
• 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.
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.
