Troubleshooting POST BIOS Beep Codes:
Troubleshooting Action
Reset the memory, or replace with known good modules.
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.
