When does the POST sound occur

The boot POST sound is when reading the memory, and it is generally a very short tick, indicating that the system is normal. The sound after it has nothing to do with the system self-test, it is generally the communication sound, you have the sound when the XP progress bar, but it has not entered the system, and this sound is not the system audio, so because it should be the interference sound, you can see if there is any interference source, such as wireless routing, Bluetooth devices, etc., I hope it can help you.

Boot computer self-test Motherboard is all powered on》CPU(**00-D5)>Memory(C1-C5)Graphics card(2B-26) >After detecting the graphics card (internal**26)Motherboard, one sound"Drops"Synchronize on screen to show logi> in self-test other devices and initialize devices.

When the XP progress bar has a dripping sound in the headphones, it may have something to do with your sound card, and some sound cards will make a sound when they are initialized.

When you run the progress bar, it is the graphics card, sound card, network card, and perform the initialization process according to the system's drivers, as well as the hard disk partition scan, IDE device scan, and the device scan

The computer works with a data instruction process After the motherboard is powered on, it is to run the CPU first and then run the memory again, and then it is to run the graphics card The sound can preliminarily determine where the fault problem is.

Is it a "drop" when the machine is turned on?

It is sounded after the computer completes the self-test of the hardware (CPU, motherboard, memory, graphics card, etc.), which means that there is no problem with the hardware, and then it "drips", and then starts to boot the system on the hard disk.

And the XP progress bar is part of the boot system, so the dripping sound happens after the memory self-test and before the XP progress bar.

As for the sound of the progress bar, I don't know what it means, is that sound the same as the sound of the self-test? Is it long or short, how long and how short, only in the headphones? You have to know all of these things to draw conclusions.

There will be a self-test sound for about 1 second after turning on the machine.

The meaning of the POST tone.

1 Short: The system starts normally. Congratulations, there is nothing wrong with your 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 replace 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 changing the block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Repeated, short ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply.

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 piece of memory.

3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

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: ROM BIOS 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.

Powering up the motherboard starts when you press the power button or press the reset button.

Until the operating system is recorded, it is to enter the boot interface of the operating system.

When I press the power button, I see the optical drive flashing and flashing, and the hard disk inside is turning. It's self-built.

1 Short: The system starts normally.

2. For a general error, you can enter the CMOS to change the incorrect settings.

1 Long 2 Short RAM or motherboard errors, you can focus the check on the memory or motherboard1 Long 2 short monitor or graphics card errors.

1 long 3 short keyboard control error, check the motherboard.

1 Long 9 Short Flash RAM or EPROM error on motherboard, BIOS corruption, replace Flash RMA

Long sound The memory module is inserted or damaged, and the memory module can be reinserted or replaced.

If the power supply and monitor are not properly connected to the graphics card, check the connection plugs and repeat the short ringing power failure.

1 Short memory refresh failure, motherboard memory refresh circuit fault, you can try to replace the memory module.

2 Short parity error, the first 64K memory chip has a parity failure, you can set the ECC check of the memory to off in the CMOS settings.

3 Short Basic 64k memory failed, memory chip check failed, you can try to replace the memory module.

4 Short clock error, timer on motherboard does not work.

5 Short CPU failures, check your CPU

6 Short A20 door failure, keypad controller contains A20 door switch failure.

7 Short CPU Exception Interrupt Error, the CPU on the motherboard produces an exception interrupt and cannot switch the column protection mode.

8 Short Showing memory error, no memory on the graphics card or showing memory error, replacing the graphics card or video memory.

9. The ROM check failed, and the ROM checksum value is not the same as the value recorded in the BIOS.

10 Short CMOS register read and write errors, and the shutdowm register in CMOS RAM is faulty.

11. Short cache error, external cacahe corruption, external cache failure.

1 long 3 short memory error, memory corruption, just replace it.

1 Long 8 Short display test error, the monitor data cable is not plugged in properly or the graphics card is not plugged in properly.
