BIOS beeps

Many people know that when you start the computer, the BIOS is loaded first, which immediately scans and checks all devices for serviceability and the ability to function normally. The BIOS beeps when Windows is booted are due to an error in the system.

Of course, all of them remember almost unrealistic, so you should always have instructions before your eyes. Or, for example, print this article and use it in the future.

It is worth noting that BIOSes from different manufacturers differ, and, accordingly, sound signals too.

For reference, I would like to say how you can define a BIOS company so that you know, just in case, if something happens, and could correctly identify the initialization error. The name is visible when the PC is booted, or with the help of some programs, for example, Everest (Aida).

Let's start with the old men. I do not think it's worth describing all kinds of signals, but it's worth mentioning only the most basic and often occurring ones.

BIOS signals from IBM:

1 short: POST completed successfully. That is, no errors were found.

Empty screen and 1 signal: the video system is faulty, which means that the information is not displayed on the screen.

2 short: the monitor is not connected.

1 long and then 1 short: problems with the motherboard are detected.

1 long and then 2 short: the video card has some kind of malfunction (Mono / CGA)

If 1 long and then 3 short: the video card has some kind of problem (EGA / VGA)

A short signal that either repeats periodically or is simply continuous: some malfunctions or defects in the motherboard or power supply.

If the signal is not at all , it means that you do not have a speaker, a motherboard or a power supply.

AMI BIOS signals :

1 short: POST completed successfully. That is, no errors were found.

1 long and then 1 short: some problems were found with the BP.

1 long and then 4 short: the video card is not detected.

2 short: the printer or the scanner is on.

3 long signals: RAM problems. Try reinstalling it or replacing the rulers.

4 short: the system timer failed.

5 short: some problems with the processor are detected.

7 short: mat. The board has a problem.

8 short: the memory of the video card produced an error.

1 long and then 2 short: the video card has some kind of malfunction (Mono / CGA)

If 1 long and then 3 short: the video card has some kind of problem (EGA / VGA)

1 long and then 8 short: no monitor or video card is faulty.

An empty screen and the absence of any signal: the processor has failed, or the bad contact at its feet.

The signal is continuous: The power supply is defective or the computer has overheated

BIOS signals from Award:

1 short: POST completed successfully. No flaws found.

2 short sounds: only minor interference was detected. It will be necessary to check the contacts and various attachments of loops, hard drives, optical drives and the like.

3 long: error caused by the controller to work with the keyboard.

1 short and then 1 long: an error reading or writing information from RAM.

1 long and then 2 short ones: the video card errors were detected.

1 long and then 3 short ones: reading error or writing information from the video memory.

1 long and then 3 short ones: reading error or writing data from ROM.

A short signal that periodically repeats: some defects in the power supply are detected.

A long signal that periodically repeats: Problems with RAM.

A repeated sound signal, then at high or low frequencies: Problems with the processor.

Continuous signal: Faults in the power supply.

And lastly ... If you have any other version of BIOS, or you want to know all the BIOS sound signals, then go to the manufacturer's website and look at the instructions. If you do not find detailed instructions on such sites, then try to search for more information on the links that are provided in the program Everest.
