Troubleshooting POST BIOS Beep Codes
Number of Beeps Troubleshooting Action
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.
