Bios two long beeps. BIOS beep codes

Today we will talk about the situation when the computer, when turned on, emits 1 long, possibly repeating signal after some time, and does not display anything on the screen.

In this situation, there are clearly problems with the equipment. Depending on the motherboard model and BIOS manufacturer, 1 long signal can indicate various problems.

Phoenix BIOS thus notifies the user that the fan in the CPU cooler has failed. In Award BIOS, such a combination indicates problems with the power supply. And for Compaq BIOS this means a violation of the correct functioning of RAM.

The IBM BIOS notifies you of video system problems with one long beep. In some cases, the user can fix such a breakdown on his own. You just need to check how correctly the video card is positioned in the motherboard slot. Perhaps the device needs to be adjusted a little, and the annoying signal will disappear.

AST BIOS in this case indicates a breakdown of the microcontroller. More precisely, the signal indicates an error detected when checking the first DMA channel. Often, to correct this situation, the user has to change the entire motherboard.

Remedies

So, the first thing to do to solve this problem is to try to remove and install the RAM, after wiping its contacts with an eraser. Ideally, take another known working memory and insert it in place of your own.

One possible reason for this signal sequence is RAM

If after this the problem does not go away, check whether the processor fan is connected to the motherboard properly and whether it is jammed. To do this, try scrolling it with your finger. The computer must be de-energized.

Checking that the CPU cooler is connected correctly

The next step in eliminating one long BIOS signal is to install a known working power supply, which you can temporarily borrow from friends or acquaintances.

The power supply is one of the possible reasons for 1 long BIOS signal

The last step in trying to eliminate the long BIOS signal during boot is to try to remove/install the video card by wiping the contacts with an eraser.

Installing/removing a video card to solve the problem of one short and two long BIOS signals when turning on the computer

If after all the described steps you are unable to start your computer, then most likely you will have to replace the entire motherboard.

An attentive user may notice that the computer makes sounds when turned on. Usually this is one short squeak from the speaker (device on the motherboard). But during operation, other signals may be emitted. Read about what they mean and how to find out what to do with them in this article.

The first thing you need to do is find out which one you have. You can find out about this when you turn on the computer, when letters appear on a black background. Look at the top or bottom of the abbreviations AMI or AWARD BIOS.

Learned? Then let's go!

BIOS BEEP: AMI BIOS

Many people know that when you start a computer, the BIOS is first loaded, which immediately scans and checks all devices for serviceability and ability to function normally. BIOS when loading Windows are a consequence of the fact that some kind of error has been detected in the system.

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

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

For reference, I would like to say, how you can determine the BIOS brand so that you know, just in case something happens, and can correctly identify the initialization error. The name is visible when loading the PC, or using some programs, for example, Everest (Aida).

Let's start with the oldies. I don’t think it’s worth describing all possible signal options, but it’s worth mentioning only the most basic and frequently occurring ones.

1 short:

Blank screen and 1 signal: The video system is faulty and therefore no information is displayed on the screen.

2 short: monitor is not connected.

Problems have been detected with the motherboard.

If

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

If there is no signal at all, then this means that you have a motherboard or a power supply.

SignalsAMI BIOS:

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

1 long and then 1 short: Some problems were discovered with the power supply.

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

2 short: The printer or scanner is turned on.

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

4 short: The system timer has failed.

5 short: Some problems have been detected with the processor.

7 short: at mat. problems have been detected on the board.

8 short: The video card memory generated an error.

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

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

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

Blank screen and no signal: the processor has failed, or there is poor contact at its legs.

The signal is continuous: The power supply is faulty or the computer is overheating

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 fastenings of cables, hard drives, and the like.

3 long: an error caused by the controller for working with the keyboard.

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

1 long and then 2 short: Video card errors detected.

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

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

A short signal that repeats periodically: Some defects were detected in the power supply.

A long signal that repeats periodically: Problems with RAM.

Repeating sound signal, sometimes at high and sometimes low frequencies: Problems with the processor.

Continuous signal: Malfunctions in the power supply.

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

It often happens that even an experienced system administrator forgets BIOS codes and signals (especially since new motherboards are already equipped with UEFI), let alone a non-professional. And knowing the signals will help you quickly, and in everyday cases, often free of charge, solve the problem with a computer or laptop that won’t start.

This is what BIOS chips from AWARD AMI and Phoenix look like.

By the way, for reference: BIOS is Basic Input-Output system or in Russian speaking, a basic input-output system. In other words, this is a low-level program that is tightly built into the chip of your computer's motherboard. The BIOS loads when you turn on the computer and is responsible for initializing its hardware components, checking their functionality and startup correctly. Then, the bootloader program starts, launching the operating system Windows, Linux, or whatever you have installed there...

Here we need to make a small digression and tell you that the signals of this very BIOS may differ depending on the manufacturer. Let's look at the most popular options, there will be three of them - AMI BIOS, AWARD BIOS, Phoenix BIOS.

Below the cut is a table describing BIOS errors.

AMI BIOS beeps

In all versions of AMI BIOS, the successful completion of self-test is one short beep, after which the installed OS is loaded. I indicated other AMI BIOS sound signals in the table:

AWARD BIOS beeps

With the correct post-test signal, everything is the same as in the previous version - one short AWARD BIOS beep means that everything is OK.

The remaining signals are slightly different - look at the table:

Phoenix BIOS beeps

The third version of signals from Phoenix. BIOS from this manufacturer is becoming increasingly rare, but still.

Here it must be said that with him everything is not the same as with the previous two. Yes, yes, the guys decided to show off and do something different from everyone else; their signals are not double, but triple. In practice, this only means that, for example, a signal about problems with power supply to the video card will look like three short beeps, a pause, three short beeps, a pause, then 4 short beeps. In the table I will write them as 3-3-4. So, let's go...

Error codes from Phoenix:

I would just like to add that in case of self-repair of a PC or laptop always disconnect it from the power supply and only then you can calmly climb inside, armed with a screwdriver and other necessary tools.

In the next article I will talk about UEFI. What is it, why did she come to us and other interesting points.

P.S. In some cases with memory errors, it helps to remove the memory sticks from the slots, wipe the contacts of the RAM boards with a regular soft eraser, and the memory is back in service! If the memory is not burned out but simply malfunctions, then you can also try swapping the boards with RAM in places across banks, provided that the memory itself that you are swapping is the same.

P.P.S. At the end of this article I simply post tables of codes for three BIOSes in the form of pictures. They can be used as a cheat sheet and saved to your phone, tablet or computer.

Cheat sheets describing BIOS signals for printing

It seems that I wrote everything I wanted to write. I tried clearly and without water, as always. If you have any questions, I answer in the comments.

In contact with

Not everyone will think about what they mean BIOS beeps when we press the PC power button. It is the BIOS that causes such sounds, which can be short or long. Different types of BIOS have different sound signals, in this article I will try to talk about all of them, as well as solve some of the problems that accompany them.

Purpose of BIOS beeps

When you turn on your computer, you hear a squeaking sound. Usually it is short and comes out of the speaker located inside the system unit. Such a signal does not bode well and indicates that the program has successfully diagnosed the POST self-test, which is responsible for checking components for serviceability. If everything is fine, this will be the signal.

On some PC models, you may not hear anything at all, but this is only thanks to the manufacturer, who did not build a speaker into the computer. Unfortunately, the absence of a speaker is not a good solution, since it will not be possible to determine a malfunction, for example, of a video card.

If some kind of malfunction occurs, you will hear a sound when you turn on the computer. There may be several of them, and they may be long, depending on what is faulty. Usually the instructions already contain all the necessary information about BIOS signals, but if you don’t already have this manual, then read this article and perhaps you will find a definition of certain BIOS signals.

Recommendation! If you decide to look inside the system unit, for example, to check the presence of a speaker, then be sure to turn off the power to the PC, and do not look immediately, but a few minutes after turning it off.

How can I find out who made the BIOS?

In this section, I will show you how to find out who made your motherboard BIOS firmware. You need to know this, because in different models, sound signals indicate different violations.

First option

The simplest thing you can do is turn on the PC and for a couple of seconds you will notice a window in which the BIOS manufacturer and some other parameters are already indicated. The most popular manufacturers are AMI And AWARD. There are, of course, others.

Second option

To do this, you need to find an item that shows information about the computer and the BIOS firmware itself. Usually the tab is called System Information.

Third option

Boot into Windows andOpen the window "Run" using keys Win+R. Enter the command there msinfo32. On the left you should be in the section "System Information". On the right we look at the point "BIOS version».

Fourth option

You can also use various utilities, for example, AIDA64 or CPU-Z. The free program CPU-Z has a tab "Pay", where you go. There is a subsection "BIOS" and all the necessary information about it.

Using the AIDA64 program, go to the section "Motherboard" on the left and click on the item there "BIOS", all information about Bios will be listed there.

How to decipher BIOS beeps?

So, we figured out the BIOS manufacturer, now I will show the designation of beeps, but only for a few versions.

BIOS AMI beeps

One of the most famous companies American Megatrends Inc. Abbreviated as AMI BIOS. In 2002 it was already such. So, the normal beep is a short sound. It means that everything is fine, after which the OS will begin loading. Now let's look at other sounds.

Sometimes the sounds are false; if you turn off the PC again and then turn it on, there is a possibility that such a signal will no longer appear. If you hear more than one short sound, but ones like those shown in the table, then you need to solve the problem.

Sound signals AWARD

The next popular manufacturer is AWARD. Let's consider its sound signals. Then someday I’ll write about all the existing types of BIOS, and also recommend a book in which everything is described in great detail.

The normal sound signal, indicating the serviceability of all computer components, is still the same as in the first option - a short signal. The remaining sounds are listed in the table below.

Phoenix beeps

In this type of BIOS, sounds are accompanied by pauses, that is, if 1 sound is heard, then there is a pause, then another sound, and another pause, and then two sounds, then the signal is recorded in the form of these same sequences of pauses and sounds - 1-1-2 . Now I will show this in the table.

This is interesting:

The most common BIOS beeps

Of course, there are many more sound sequences for different types of BIOS, and there would be much more tables here. Therefore, I decided to consider the most popular signals that most users encounter.

• 1 long and 2 short sounds– usually this signal indicates problems with the video card. Check whether the video card is inserted well into its slot, also do not forget that due to dust and dirt there may be problems with connecting devices, so it is better to clean everything. Take out the video cards, wipe the contact tracks with an eraser, and do it very carefully. Then put it back in. If the difficulty persists, then you can try inserting the video card into another slot or switching to the built-in one, provided that it is on the motherboard. We are talking about integrated.

• 1 long sound- indicates a problem with the RAM.

• 3 short sounds– Again errors in the random access memory device. There is the following option - remove the RAM modules and clean the contacts, as well as the slots from dust and dirt, swap them, replace them with other RAM modules. Alternatively, you can reset the BIOS.

• 5 short sounds– this signal indicates a processor malfunction. It is possible that you purchased a new processor that is not compatible with your motherboard. Also check all contacts and clean any dust.

• 4 long sounds– the signal indicates problems with the cooling system, that is, with coolers. Perhaps they are completely faulty or work slowly. There are two options: clean them from dust, or change them.

• 1 long + 2 short sounds– a malfunction of the video card or from the RAM connectors.

• 1 long + 3 short sounds– may also indicate problems with the video card and RAM, or something with the keyboard. We'll have to check everything.

• 2 short sounds– I can’t say for sure, check your documentation. There may be a problem with the RAM.

• Several short sounds- just count how many sounds and see if such a combination is in the table.

• No PC boot or BIOS sound– if there is no sound, then most likely you do not have a speaker, or it is faulty. If the computer does not boot, check the power supply.

Tips for troubleshooting problems with your computer emitting BIOS beeps

I almost never had any components fail, and sound signals appeared only due to poor contact of some components. For example, the RAM modules or video card were inserted poorly. Sometimes something just went wrong and simply restarting the computer helps. Sometimes it can help in solving problems altogether.

I want to say that people who do not know should not take any action. If you have friends who can help, then contact them, or go to the service.

1. Sometimes you can correct the situation like this: remove some component and wipe its contact from dust, and also blow out the connector. Then put everything back in. You can clean the contacts with alcohol and a dry cloth or an eraser.
2. Look at all the components and elements located inside the system unit. Is there a smell of burnt components, swollen capacitors, oxide and other bad phenomena?
3. Before you climb inside the system unit, disconnect it from the power supply, and also remove static electricity from yourself. You can simply touch the power supply itself with your hands.
4. Do not touch the board pins.
5. Never use metal tools to clean modules.
6. Assess the situation before starting work. Your computer is under warranty, but you don’t even have work experience? Then give it back under warranty, or ask a knowledgeable friend to help.
