What s going on with the 9 beeps of the computer host 20

The problem of the power supply, if you don't change it, it will not be 3 times in a row, or it will ring continuously!

Prompt for boot self-test, under normal circumstances, everyone hears a "drop" sound when they turn on the computer, and the computer starts successfully, but if the host hardware fails, such as no beep, the computer does not respond, or there are multiple honey sounds of different lengths, then this is the host failure.

phoenix bios1 Short: The system starts up normally.

1 short, 1 short, 1 short: The system initialization failed.

1 Short 1 Short 2 Short: Motherboard error.

1 short 1 short 3 short: CMOS or battery failure.

1 Short, 1 Short, 4 Short: ROM BIOS verification error.

1 Short, 2 Short, 1 Short: The system clock is incorrect.

3 Short 2 Short 4 Short: Keyboard controller error.

3 Short 3 Short 4 Short: A memory error is displayed.

3 Short 4 Short 2 Short: Error is displayed.

4 Short, 3 Short, 1 Short: Memory error.

4 short, 4 short, 1 short: The serial port is wrong.

4 short, 4 short, 2 short: the parallel port is wrong.

ami bios1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3 Short: The basic memory check of the system fails. Change memory.

4 Short: The system clock is wrong.

5 Short: There is an error in the CPU.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: BIOS chip check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

award bios1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 1 short: There is an error in the memory or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. Reinsert the memory module, or replace the memory.

Memory ECC verification error. X0D X0A3 Short Beeps: The self-test of the basic memory (the first 64KB capacity) of the system fails.

CPU error. x0d x0a6 beep: Keyboard controller error.

Displays memory errors (such as showing memory corruption). X0D X0A9 Beeps: Motherboard FlashROM or EPROM verification error (e.g. BIOS corrupted by CIH virus).

x0d x0a1 long 3 short beeps: memory error (e.g. memory chip corruption). x0d x0a1 long 8 short beeps:

x0d x0a2 short beep: General error. You should go to CMOSTathe and reset the incorrect options.

Wrong monitor or display card. x0d x0a1 long beep 3 short beeps: The keyboard controller is wrong.

The memory is not plugged in properly or the chip is damaged. X0D X0A keeps ringing: The monitor is not connected to the graphics card.

You can refer to the above explanation, and then repair the mistakes according to the mistakes.
