What is the reason for three short beeps when the computer is turned on? How to solve?

The three short beeps when the computer is turned on is because the system's basic memory (the first 64KB capacity) failed to self-test.

Solution:

1. Remove the memory, use an eraser to carefully clean the gold fingers on both sides of the memory, and then insert it back into the memory slot.

2. Replace with new memory.

The following lists the meanings of two common BIOS power-on self-test beeps:

AMI BIOS:

1 short beep: Memory refresh failed.

2 short beeps: Memory ECC verification error.

3 short beeps: The system basic memory (the first 64KB capacity) failed to self-test.

4 short beeps: The system clock is wrong.

5 short beeps: CPU error.

6 short beeps: Keyboard controller error.

7 short beeps: The system real mode is wrong and cannot enter the protection mode.

8 short beeps: memory error is displayed (such as memory corruption).

9 short beeps: Motherboard FlashROM or EPROM verification error (for example, the BIOS is damaged by CIH virus).

1 long 3 short beeps: memory error (for example, the memory chip is damaged).

1 8 long beeps and short beeps: Display system test error (such as poor contact of the monitor data cable or graphics card).

If it is Award BIOS

1 short beep: the system starts normally.

2 short beeps: General error. You should enter CMOSSETUP and reset incorrect options.

1 long beep and 1 short beep: Memory or motherboard error.

1 long beep and 2 short beeps: Monitor or graphics card error.

1 long beep and 3 short beeps: Keyboard controller error.

1 long beep and 9 short beeps: Motherboard FlashRAM or EPROM error (for example, the BIOS is damaged by CIH).

Continuous long "beep" sound: The memory is not inserted properly or the chip is damaged.

Keeping sound: The monitor is not connected to the graphics card.
