Have you encountered issues with unable to boot the computer and it just gives a beep sound? The reason is your computer might have encountered an error at the time of POST (Power On Self Test). The BIOS (Basic Input Output System) uses beeps or combinations of beeps through an internal speaker to indicate the encountered specific problems.This language used by the BIOS depends on the model and manufacturer.
The main BIOS manufacturers are
- AMI (American Megatrends, Inc.)
- Phoenix Technologies
How to find the BIOS manufacturer
As soon as you turn on the computer, you will be able to see the BIOS screen and the manufacturer name on it.
American Megatrends Inc. (AMI BIOS)
* If BIOS beeps 1-3 times and fails to boot = problem most likely lies with memory modules
* If BIOS beeps 4-7 or 9-11 times and still fails to boot = problem with your motherboard or your expansion cards
* If BIOS beeps 5 times = most likely a processor error
* If BIOS beeps 8 times = direct your attention to the system video adapter
Phoenix Technologies (Phoenix BIOS)
* If BIOS beeps once, pauses, beeps twice, pauses, beeps twice, pauses, and beeps three more times = direct attention to BIOS itself
* If BIOS beeps once, pauses, beeps four times, pauses, beeps twice, pauses, and then beeps once more = alerting you to a problem with the CMOS (complementary metal-oxide semiconductor), which is the memory that stores the BIOS.
* If BIOS beeps once, pauses, beeps three times, pauses, beeps once, pauses, and beeps one more time = error with memory modules
Phoenix and AMI both have downloadable PDF documents that detail beep codes and what they refer to. Check their websites for more details.
