Long beep speaker when you turn on the computer. Computer motherboard sound signals

Hello everyone, noticed that the computer, when turned on, makes a squeak, and then loaded ... This is all good, and if it starts to squeak anything and nothing happens on the screen - then this reason to think about and try to figure it out, why does the system unit be silent every time , including a computer, heard as a system unit makes a squeak. This signal shows performance. hardware, the decoding of which has few. So we will try to figure out why the system unit is sicked?

Deciphering system block signals

As you know, the system unit accommodates many special-purpose devices. When turned on, the computer makes a test signal this provision (fan, processor, I / O devices, memory, video cards, etc.).

Deciphering the compartment published by the system unit is given in Table:

Correction of hardware breakdown

If errors occur in separate hardware parts that the squeak is evidenced by system BlockIt is necessary, first of all, check the connections of these devices with the power supply.

When there is no signal and with it any signs of computer life (buttons display does not highlight, the fan does not make noise, no image on the monitor), You can state the power supply malfunction, then it will be necessary to replace it. If when you click on the power button, at least a fan reacts, it is possible to buy a new processor. Although it will not be superfluous to check the power cord motherboard: Perhaps he moved away.

If there are errors in the BIOS operation, you need to go to the settings menu using the DEL key and set the optimal parameters. However, not everyone knows the correct settings values, in which case it is better to install them by default (key F5), the F10 and ENTER key are pressed to save the changes. Also reset bIOS settings You can, removing the battery on the motherboard for a second and putting it back. If it does not help, you will have to reflash the menu at the hardware level.

The absence of the keyboard is checked for the presence of a plug from it in the PS / 2 socket. It was found that it is connected, it means that the device is not proper, most likely, it will be necessary to replace.

Errors in the operation of the RAM are first checked for the presence of plank data in the motherboard connector. Then the memory cards are removed, they are cleaned with dust and in turn plug into slots. At the same time, each time the system unit is turned on. If a squeak was heard, it means that this fee is completely.

Video Card Settings Maps are held in BIOS. Checking the physical serviceability of the device is made using another obviously operating video adapter. If it was found that the device does not work, then it is necessary to clean it from dust and see whether the plug is connected to the board for power, as it is served as a separate cable to which you do not connect anything else. You can also check the display of the display, and whether it works. These manipulations do not help, it means that the video card is needed.

You can try to fix the system timer breakdown if you need to reset the BIOS, otherwise you will need to repair or replace the motherboard.

Checking the operation of the processor is to clean it from dust, as well as to exclude the overheating of the radiator through non-functioning of the fan.

Record errors in CMOS occur when flashing BIOS. Cash memory is corrected when resetting the BIOS or when repairing a computer and replacing the processor. In order to reset the BIOS, it is not necessary to remove the battery, you can apply a special jumper called jumper. Where it is located, you can learn from the manual on the use of the motherboard.

If it fails to repair yourself, it is better to contact the specialists who will give a guarantee that the squeak of the system unit will not happen again, but you already know why the system unit is frightened and what it threatens you.

In contact with

Good day. Today we will talk about why floating computer And what the signals Bios. (But he does it precisely) gives you.

Although it would begin to start this article differently.

The malicious energy turned off the light, and when turned on, the computer became incomprehensible to squeak and refused to work? Brother kicked the system unit, after which the latter makes one exile and does not turn on? Computer sickens so that everything is scary in the district?

You can of course drop the brick on the energy sector and hang your brother for the legs to the ceiling, but how to determine what happened to the computer and what does this most hazing mean?

This material is just devoted to sound signals (or their absence) of the computer, namely their decoding.

Let's start.

BIOS signals - input

Let's understand why the computer beeps and what's what

Signals vary depending on the type of BIOS, which lives in your mat. You can find it in, actually, the BIOS itself (DEL button at the earliest stage of the computer).

How about what other bios you can see on the BIOS. Generally speaking, all modern motherboards have long switched to UEFI, but the essence of this has changed not much.

However, let's be essential.

Award BIOS - Floating Computer - Decryption

The minimum list is approximately like that:

• Continuous signal - faulty. Replacement required.
• 1 short signal - Errors are not detected. Typical behavior of a working computer - the computer is loaded normally.
• 2 short signals - Multile errors were found. A proposal appears on the monitor screen to enter the CMOS Setup Utility program to correct the situation. Check the reliability of the fastening of the loops in the connectors and.
• 3 long signals - Keyboard controller error. Restart the computer. You may need to replace the motherboard.
• 1 long + 1 short signals - problems found with. Check the installation of memory modules. Either replace other memory modules.

• 7 short signals - faulty motherboard.
• 8 short signals - Problems with video card.
• 9 short signals - error checksum of the contents of the BIOS chip. A corresponding message may appear on the monitor screen. It requires either the replacement of the chip, or overwrite its contents (if it is flash memory).
• 10 short - it is impossible to record in CMOS memory. CMOS or motherboard chip replacement is required.
• 11 short signals - Faulty external cache memory. Cash memory modules are required.
• 1 long + 2 short signals
• 1 long + 3 short signals - Faulty video card. Check the monitor connection with a video card connector. You may need to replace the video card.
• 1 long + 8 short signals - Problems with video card, or monitor is not connected. Check again the installation of the video message in the expansion slot.

Let us turn to the Phoenix and its signals.

Here is such a big list turned out. View BIOS type "Ah can be in the BIOS itself.

Starts with diagnostics. You can often use the diagnostics tools of the PC itself, or rather BIOS. If everything is in order, 1 signal is fed to the speaker. If earlier, during normal operation, you also did not hear any signals from the speaker, then you need to check if it is in general in the system unit. He looks like in most cases like this:

If you hear a few sounds, the hardware error is most likely. The combination of speaker signaling indicates a specific error. Depending on the BIOS manufacturer "and they may differ from each other. Before deciphering signals, you need to find out which BIOS on your motherboard. Make it in several ways:

1. View documentation for the computer, namely, the instructions for the motherboard.
2. View the name when downloading or going to install BIOS.
3. Open the lid of the system unit and read the name of the chip with the BIOS.

When the manufacturer finds you can verify the combination of the speaker-published with the data of the tables below:

Have you noticed that when loading the system, the computer makes a short sound? Let's figure it out what is the sound, what other sound signals are and what do they mean?

What do bios sound signals when the computer is turned on?

Contemporary computer system Consists of the following components:

• motherboard;

  

• cPU;

  

• rAM (RAM);

  

• video card;

  

• hard disk (Winchester);

  

• power Supply;

  

• sound card;

  

• monitor / display (on laptops);

  

• lAN card;

  

• peripherals (keyboard, mouse).

  

Main PC board - maternal or systemic. It is it that combines all computer elements - built-in and peripherals, and also controls them.

On the board there are several control microcircuits, of which we are interested in the BIOS chip. His distinctive trait - availability of own permanent memory (flash memory), which, like a hard disk, stores important information. This microcircuit receives electricity from the battery, which is located on the motherboard.

BIOS - basic I / O system - program, the main purpose of which is the initial testing of the PC and the control of control in boot sector Winchester to download the installed operating system. If a operating system Not installed, Bios will try to find another boot device - CD or DVD drive, Flash device.

The operation of the OS will occur if the critical errors have been detected during the testing of PC devices. Otherwise, the error code will be shown on the display and one or more signals will sound through the system speaker, according to the error code.

This is necessary if for some reason it is not possible to observe information on the screen. For example, the video card or the display itself is faulty.

When you click on the PC, the POS program is launched by the POST program that produces self-testing.

It conducts a survey of all the main components of the system and compares the current configuration with the one that was recorded in memory during the previous download. If any changes in the system have been made, POST will make corrections in own memory CMOS.

Tip! The BIOS SETUP subroutine allows you to change some boot and hardware settings. For example, you can disable some embedded devices if they are not needed, adjust the operation of the processor thermal control, etc.

If one or more devices are recognized as defective or not supported by the system, the user will hear a combination sound signals And it will see the corresponding message on the monitor.

The sound of these signals depends on the model of the motherboard, or rather, the BIOS microcircuit manufacturer.

Major manufacturers of BIOS chips

If from the point of view of the main settings the name of the manufacturer does not matter much value, since they are standard for all, then when identifying troubles for sound signals, you need to know the manufacturer of the factory firmware program.

Basic types Bios:

1. Award BIOS is Award Software.
2. AMI BIOS - Manufacturer American Megatrends.
3. Phoenix BIOS - Phoenix Technologies company.

It is less likely to have chips of manufacturers of computer electronics Intel, IBM, COMPAQ, TOSHIBA, Dell.

Sound alert system is a combination of long and short signals.

AWARD BIOS SIGNAL TABLE

One of the most common manufacturers.

AMI BIOS Signal Table

Phoenix Bios Signals Table

This manufacturer uses BEEP format codes: signal-paus signal.

On a note! For example, 1-1-2: signal-pause signal-pause-two signal.

Addition! DMA - Direct access mechanism to RAM from peripheral devices Systems. It is required to speed up the work of the CPU and the system as a whole. DMA channel errors can appear if there are appropriate difficulties with peripheral devices.

If after testing the BIOS PC does not load, the video system does not work and there is a suspected fault specific device, you should not hurry to buy a new spare part. It is important to make sure that the problem is in this detail. For example, a video card or RAM modules can be removed and check on another PC. Could be faulty or contaminated (oxidized) connectors on the motherboard or any chips.

Some components will not work correctly on unsupported motherboards, in which case they should be replaced.

Video - Computer fries when turned on. What is it?

AMI BIOS All versions inform the user about the successful end of the self-test procedure with a characteristic "pisk" - one long sound signal, after which the control is transmitted to the loader of the operating system.

In order for you to hear this beep, the computer block or laptop must be equipped with a system speaker - a built-in "Cook". Alas, this condition is not always performed. Sometimes the manufacturer saves a penny accessory, and loading occurs in complete silence.

If something went wrong, in the process of passing the POST procedure, certain problems were identified, the BIOS of the computer will report this with a combination of several audible signals indicating the failed component. In most cases, when problems do not affect the video card, you will see an error message on the computer screen. But if you cannot initialize the video card (for example, it itself is a source of problems), sound signals remain the only way to localize the problem.

The old versions of Ami BIOS used a sufficient number of all sorts of combinations. All of them are reduced in one table.

Do not forget all manipulations with computer hardware components, somehow replacing memory modules, extracting and adding extension cards, etc. It can only be done if the computer is fully de-energized - it must be physically disconnected from the mains. Before opening the system block case, it is recommended to remove the power block of the system unit from the outlet. By this, you will provide the lack of motherboard duty, plus, secure yourself from possible electric shock.

Modern versions of AMI BIOS are much more modest, the number of signals has significantly reduced: only simple combinations of short signals are used.

Moreover, in the last AMI BIOS revisions, sequences of the 1st long, 1st, 3, and 6-, and 7 or 8 or short beeps remain, the remaining combinations are no longer used.

Separately, it is worth noting a continuous beep-changing sound, resembling siren. It can be caused by two reasons: power supply fault, or overheated by computer. If you have access to the intenshes of the system unit, check all power connectors on the motherboard, check the normal adjacent of radiators, the operation of all fans on the coolers.
