May I ask what happened when the computer beeps every 2 seconds when the computer is turned on, and

Judge for yourself! Mainly memory and graphics cards.

1 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.

ami bios

1 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.

1 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, 2 Short, 1 Short: Clock error.

4 Short 2 Short 2 Short: Shutdown error.

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.

Comparison table of the meaning of the old Award BIOS alarm sound and fault.

A short system boots normally.

2. The short CMOS setting is incorrect, and it must be set again.

1 long and 1 short memory or main version error, change memory or master version.

1. The long and 2 short monitors or graphics card are wrong, and the display card may not be inserted properly.

1 long 3 short keyboard controller error, master issue.

1 long 9 short Flash RAM or EPROM error of master BIOS, serious master issue.

Repeating short rings Power issues.

The memory is not plugged in tightly or is corrupted.

There are two possibilities: the first is that the memory is not read, unplug the memory, wipe it and plug it back in, the second is that the graphics card is loose, check it, or two graphics cards, first choose an independent graphics card, do not insert the integrated one.

During the POST, if a fault occurs in the computer, it sometimes rings continuously, and different rings represent different error messages.

You can't answer this question.

There are many reasons for this.

The memory motherboard can cause regular errors.

Monitors or graphics cards can also cause and so on.

You'd better go to the pits.

Unplug the keyboard first and turn it on - if it still doesn't work, check whether the memory is loose under the single memory.

If there is a problem with the host, take it for maintenance.

It should be that the memory module is loose, unplug the memory and erase the gold finger with an eraser, and then install it to boot it up.

If the CPU fan or power supply fan is running abnormally、、、 detect it or replace it directly.

I didn't find the reason, it's not the memory, it's not easy to do.

If you don't have the testing equipment at hand, you can only check item by item in the following order:

1. First, restore the motherboard BIOS settings to the initial state, or directly short-circuit the terminal (clear) to eliminate the saved settings.

2. Insert only one memory module to see if it starts normally.

3. Remove the CPU, clean up the dust, and then install it and start the computer.

4. Remove the graphics card and clean up the slot dust.

5. None of the above is enough, only find a computer with compatible configurations and swap it in the order of 2-4 above, and you can find the component that has a problem.

The long beep is that the memory is not plugged in, and the short beep is that the CPU is not plugged in. This is a buzzer, which is installed on the motherboard to prevent people from operating the stuff by mistake.

Check for memory errors and reseat it

The memory module is loose, unplug and reinsert, if it's good, please collect me, thank you.
