When computer crashes, main board beeps. This beep is not random, but a normal beep. Each beep indicates a problem with different hardware. This sound is an audio prompt. issued by BIOS when a malfunction is detected during self-test, so that we can better understand location of computer malfunction. So what does motherboard beep mean? Today Grasshopper will tell you about meaning of sound of a computer alarm clock. Hope this helps you!

The main board is equipped with a buzzer

1. Award BIOS Beep Meaning:

1 short: The system starts normally. Congratulations, your car is fine.

2 short: general error, please enter CMOS settings and reset invalid parameter.

1 long and 1 short: RAM or motherboard error. Try another memory, if it still doesn't work you will have to replace motherboard.

1 long and 2 short: monitor or graphics card error.

1 long and 3 short: keyboard controller error. Check motherboard.

1 long and 9 short: Wrong motherboard flash or EPROM, and corrupted BIOS. Try a different block of Flash RAM.

Continuous beep (long beep): The memory module is loose or damaged. Reinstall memory module, if it still doesn't work just replace one memory module.

Continuous beep: The power supply, monitor, and graphics card are not properly connected. Check all plugs.

Repetitive short beeps: There is a problem with power supply.

No sound or picture: power problem.

2. AMI BIOS self-test beep meaning:

1 short: Failed to refresh memory. Replace memory module.

2 short: ECC memory check error. This can be solved by setting ECC memory check option to "Disabled" in CMOS settings, but most fundamental solution is to replace some of memory.

3 short: System main memory check (first 64 KB) failed. Change memory.

4 short: system clock error.

5 short: Central processing unit (CPU) error.

6 short: keyboard controller error.

7 short: real mode system error, unable to switch to protected mode.

8 short: display memory error. If there is a problem with display memory, try replacing video card.

9 short: BIOS ROM checksum error.

1 long and 3 short: memory error. The memory is damaged, just replace it.

1 long and 8 short: display test errors. The display data cable is not inserted correctly or display card is not inserted firmly.
