Every time the computer boots up, system unit emits a beep. Not everyone knows that this is a signal indicating the health of the system unit. And only a few know the decoding of these signals from the "system unit".

That's what we'll talk about. If you are reading this material, I recommend printing it now. When decryption is needed, it will not work to get out on the Internet. :)

So what is the "sistemnik" beeping about. These signals are test results hardware computer (cooler there, RAM, vidyuha, etc.). Every time you boot your computer, it tests the hardware, and reports the results with this very squeak. Deciphering the squeaks of the system unit below.

* One short beep.
Decryption:
Everything is fine. Test passed successfully. You can continue to work. It happens that some system units do not squeak at all at this moment.
* No squeak, no image on the computer screen.
Decryption:
Malfunctions in the power supply, or processor.
Correction:
First, check to see if the power cord is plugged into an outlet. If everything is in order, try connecting a known working device to the power filter (such a cord with a box in which there are many sockets, there is also a switch button, usually red). A phone charger is suitable, of course, with a phone connected to it. Check all sockets network filter. If the outlet is working, the phone will charge. Next, we check if the power supply starts up when the computer start button is pressed. In this case, the cooler (fan) of the power supply should at least twitch. If there is movement, look for new processor, otherwise - new block nutrition. You also need to check the motherboard power cable. It may happen that he moved away.
* One long continuous beep.
Decryption:
Power supply defective.
Correction:
Purchasing a new power supply.
* Two short beeps.
Decryption:
Minor bugs in BIOS settings.
Correction:
Go into the BIOS and set the optimal parameters. Exit to the BIOS is usually done with the key. If you don't know what to change, then set the default values. To do this, press the button. To exit and save - , . Some versions of the BIOS themselves prompt conflicting settings items with backlighting. Also, you can reset the BIOS settings by removing the motherboard battery for a few seconds.
* Three long beeps.
Decryption:
The keyboard is missing.
Correction:
Plug the keyboard into the PS/2 socket. If this does not help, you will have to change the keyboard.
* Three short beeps.
Decryption:
RAM error.
Correction:
To do this, you need to check if there are memory bars on motherboard. Don't laugh, it happens. Then you need to take out all the memory sticks, carefully sweep away the accumulated dust, and stick the memory stick in turn, and start the system unit. If on some bar the "system unit" squeaks, then this may mean that the bar is faulty.
* One long and one short beep.
Decryption:
Doesn't work properly RAM.
Correction:
It is possible that one or more memory sticks are conflicting with each other. You need to alternately stick one stick of memory and try to start the computer.
* One long and two short beeps.
Decryption:
The video adapter is not working properly.
Correction:
Fix settings in BIOS.
* One long and three short beeps.
Decryption:
The video adapter does not work.
Correction:
Check the performance of the video card. To do this, you need another, obviously working video card. You can also try to remove the card, remove dust from the slot, and stick the card in place. And do not forget to check if the card has additional power plugs. Power to such video cards must be given by a separate cord to which no device is connected. I also suggest checking if the monitor is connected and working. Try blowing out the plug connecting the monitor to the computer.
* One long and eight short beeps.
Decryption:
The video adapter is not working or the monitor is not connected.
Correction:
Same as written above.
* One long and nine short beeps.
Decryption:
Error reading BIOS data.
Correction:
Try resetting the BIOS settings by removing the battery. If that doesn't help, then flashing the BIOS. But that's another story, requiring a separate article. I will try to write it as soon as possible.
* Four short beeps.
Decryption:
The system timer does not work.
Correction:
You can try resetting the BIOS. But, unfortunately, it rarely helps. There is only one way out - to change or repair the motherboard.
* Five short beeps.
Decryption:
The processor is not working properly.
Correction:
Try to clean the dust from the processor slot, make sure the heatsink is clean and the processor temperature is low.
* Six short beeps.
Decryption:
Keyboard defective.
* Seven short beeps.
Decryption:
Motherboard malfunctions.
Correction:
Send the motherboard in for repair, or purchase a new one.
* Eight short beeps.
Decryption:
Faults in the video memory.
Correction:
Take the video adapter in for repair, or purchase a new one.
* Nine short beeps.
Decryption:
Incorrect BIOS checksum.
Correction:
Usually it is proposed to reset the BIOS settings and allows you to work further. In which case, you can reset the BIOS by removing the battery.
* Ten short beeps.
Decryption:
Error writing data to the CMOS chip.
Correction:
This error can occur when flashing the BIOS. Therefore, we will describe this part in another article.
* Eleven short beeps.
Decryption:
The cache is not working properly.
Correction:
Reset BIOS. If this does not help, we carry the computer for repair, or install a new processor.
* Repetitive long beeps.
Decryption:
Faulty or incorrectly connected RAM.
Correction:
Reconnection of memory sticks. Calculation of the faulty, by connecting in turn and starting the computer. Dust cleaning.
* Repetitive short beeps.
Decryption:
The power supply is not working properly.
Correction:
Checking the performance of the power supply, checking the cords for breakage, checking the surge protector, and, last but not least, replacing the power supply.

That's all. There will be questions - ask.

PS: To reset the BIOS, instead of removing the battery, you can use a special jumper - a jumper. Its location can be found in the motherboard documentation.

Addition: BIOS signal encodingsif the computer died.

Greetings to all readers of the site Country IT. In this article, I want to tell you about BIOS beeps. If your computer has a built-in speaker, you will hear a single beep when you restart or turn on your computer. It tells us that the computer components are working and the POST system did not reveal any problems. But it often happens that, if with, then it starts to make BIOS sounds.

Many users do not know what they stand for and carry the computer to the workshop. We will try to figure out on our own what the BIOS is beeping about and identify the cause of the malfunction. Since different motherboards have different basic input/output systems, first you need to determine which motherboard is on the computer. But everything is in order.

As I said above, we need BIOS beeps in order to find out which component of the computer is malfunctioning. As a rule, if it works properly, then when you turn it on, we hear one short signal. Such signals are emitted by a special speaker connected to the computer motherboard.

Note! Your computer may not emit any beeps unless a speaker is physically connected to the motherboard. The absence of a speaker on many boards is most likely the fact that the manufacturer is trying to make the production of its goods as cheap as possible.

Many of you have probably already wondered: “What threatens me with using a computer without a speaker?” It would seem that such a trifle that is not needed at all with a working computer, but many people begin to think about it when the computer breaks down. In this case, if a speaker is connected, the computer will emit a special beep or a series of beeps in a specific sequence. To decipher such signals, you can refer to the motherboard manual. But as a rule, this book either does not exist, or nothing in it is clear to many of us. Therefore, below we will consider how to decode BIOS sound signals. But first you need to determine its manufacturer.

To decipher the BIOS beeps, you need to know the manufacturer. Since different motherboards installed a different basic input/output system. You can find this information different ways. For example, when you turn on your computer, you see a black screen with information about hard drives. Here on this screen, as a rule, the version and manufacturer of the BIOS are indicated at the top.

If a necessary information quickly replaced by another, and you do not have time to see everything, then you need to press the "Pause" key. If, when you turn on the computer, you get a splash screen from the manufacturer of the motherboard, then you need to press the "Tab" key to remove it.

The next way to find out the version of the basic I / O system is to enter it. To do this, when you turn on the computer, press the key "Del", "F1", "F2" or another. Depending on the . After that, find the System Information section and look at the BIOS version and manufacturer.

Another way, while simple enough to find out the version and manufacturer of the BIOS, is to look using the System Information utility. To do this, press the hot key combinations “Windows + R”, and in the “Run” command window that opens, type “MSINFO32”. A window with system information will open, in which we look at the line "BIOS version"

Finally, we will find out the version of the basic input-output system through the "CPU-Z" program.

We have already used it more than once in previous articles. Therefore, we launch the program, go to the board tab and look at the BIOS information.

Decoding BIOS signals.

After we were able to determine the manufacturer of the BIOS. You and I need to move on to decoding the signals.

AMI BIOS (American Megatrends Inc.) is probably the most famous BIOS manufacturer for motherboards. If during the self-test, POST did not find any problems, then you will hear a single short beep. After it, the operating system will immediately start loading. If you hear other signals, then you should be alert, listen and decipher them.

Below is a table with the decoding of AMI BIOS audio signals.

As a rule, if the computer starts to squeak, then sometimes a banal reboot or de-energizing the system unit for a while helps. If this does not solve the problem, then at the end of the article I will tell you how to deal with the main malfunctions.

If you have a motherboard with this BIOS version, then special sounds are characteristic of it. that look like this. For example, code 1-1-4 would sound like one pip, pause, another pip, pause again, and then four pip. Such a sound will indicate an incorrect BIOS ROM checksum. In order to decipher the BIOS beeps on the motherboard with Phoenix BIOS see table below.

Another popular BIOS manufacturer for motherboards. It is installed on many motherboards. Its display interface is classic and has not undergone any global changes for 10 years.

Sound signals something similar to AMI BIOS. Therefore, it will not be difficult for you to decipher them. The table is shown below.

The most common BIOS sounds and what they mean.

I propose to consider the most common beeps that we can hear when there is a problem with a computer.

• A long single BIOS sound when you turn on the computer - most often indicates problems with RAM;
• One long and two short - if you hear such a signal, then there is a high probability that there are problems with the video adapter. To get started, just pull it out and clean the contacts. For example, an eraser will do. Also clean the computer from dust if you haven’t done it for a long time;
• One long and three short beeps - this signal configuration indicates problems with the video card, RAM or keyboard;
• Three short beeps - more often they talk about problems in the operation of the RAM. To solve the problem yourself, remove the memory module from the slot, clean it. If there are several memory modules, try starting the computer first with one, then with two, and so on;
• Five short BIOS signals tell us that the central processor is faulty. If you hear these beeps after installing a new CPU, it may not be aligned with the motherboard or you did something wrong. If the processor has not changed, then it may have failed or there is no contact in some place;
• Four long beeps - often tell us about the low speed of the cooler that cools the processor;
• No signals, the computer does not turn on - most likely you have a problem with the power supply. Replace it with a correct one.

Let's summarize.

Today we have discussed about BIOS beeps. As a rule, if when you turn on the computer you hear a whole serenade from your computer instead of the usual single peep, now you know that you need to decipher the signals. In most cases, you can solve the problem yourself. Very often, the problem is solved after cleaning the contacts of the computer components or by simply rebooting and de-energizing the system.

When connected to the network, the computer emits a beep. This is how the hardware informs the user that it is ready to work. But sometimes the computer emits a series of beeps at various intervals, and flatly refuses to boot. This indicates that there are problems, and the problem may lie in software or mechanical damage.
You can find out the cause of the malfunction by the frequency and frequency of sound signals

However ordinary user it is difficult to understand this alphabet, so we decided to make an article where the decoding of Bios signals will be given.

What are the beeps talking about

If the computer beeps when turned on, then everything is not so bad. At least the motherboard is fine. Much worse if . This indicates system problems that can only be fixed in the workshop. If the hardware is buzzing, you need to try to find out the cause. Some breakdowns can be repaired on their own. It is worth noting that the malfunction may be software or technical in nature. In the latter case, having heard a squeak, you need to check that the computer is connected correctly. The power cord may have come loose or there may be no power. In the latter case, the computer does not turn on.

If the connection is normal, the system unit is buzzing, but the image does not appear, you are dealing with a software failure. But you can try to clean the computer from dust. They do it like this:

• We remove the front cover of the system unit (the computer is disconnected from the mains), take out the RAM and video card.

fig.1. Slots of seized devices should be cleaned with a soft brush

fig.2. We remove pollution from the memory card and video card

• We insert the parts into place, and try to turn on the computer.

If the download was successful, then the reason was dust that clogged the contacts of the motherboard. If after cleaning, the computer continues to beep, then the problem is more serious than it seemed at first glance. Perhaps the power supply is faulty or the software has crashed. In any case, it is recommended to give the computer for diagnostics to a service center.

Important! The computer beeps with any system malfunctions. If you know what the series of beeps means, you can fix and possibly fix the problem.

Table of sound signals

The signals at the start of the computer are a kind of Morse code, with the help of which the hardware communicates with its owner. There is a Bios signal table with which you can decipher beeps. You just need to find out which BIOS version is installed on your PC, check the table below, and determine the cause of the beeps

If the computer freezes when turned on, then this is a software malfunction. In this case, one short beep is heard when the computer is turned on, indicating that the system is booting normally. But operating system hangs at the loading stage. It is possible that the computer does not see the bootloader. Faced with such a situation, you need to check the priority BIOS boot. It is possible that the download from digital media was set by mistake. To fix the problem, just reset the boot options.

Hello, friends! In this article I want to consider another sore subject - what is the computer beeping or bios beeps. The emitted signals are rare, but even in these cases you must know what to do. Usually, the computer emits a single beep - one short one, and the operating system starts to load. And only when something is wrong with the computer, instead of this pleasant sound, annoying combinations of long and short beeps appear. So the computer is trying to tell us what it needs to load the operating system correctly.

If non-standard bios beeps appear in 50% of cases, you can restore the computer to working capacity without using the services of service centers.

In this article, we present the decoding of bios sound signals from popular manufacturers. And, consider the measures that can and should be taken to revive your computer.

Methods for restoring the health of a computer with various BIOS signals

Faulty RAM

Turn off the computer, remove and re-insert the memory modules. You can read how to do this.

If it didn't help. We turn off the computer, take out the memory modules, clean the contacts with a grater, blow off the remnants of the grater from the memory strips, blow through the memory slots and insert the modules back. If everything worked, you can run a RAM test.

If you have more than 1 memory module, then you need to insert one module at a time first into the first slot, then into the second, and so on. Perhaps one of the modules is out of order or the memory connector is faulty.

If all else fails and the bios beeps are repeated, you need to replace the RAM.

Faulty power supply

Turn off your computer. Disconnect and reconnect all connectors including the cable from the outlet to the power supply. Hard drives may not be connected. If we hear 1 short bios beep, turn off the computer, connect all components and turn it on again.

If that doesn't work, you need to replace the power supply. How to choose - and. Before buying a new one, it is advisable to take a working one from a friend and try it.

Faulty keyboard (keyboard error)

You need to turn off the computer, disconnect the keyboard connector and reconnect it. In 70-80% of cases, this restores the system's performance.

The computer can not be turned off if you have a USB keyboard

If it does not help and the bios sound signal remains, you need to replace the keyboard. It is also advisable to take a known working one and check it out.

Faulty graphics adapter

We apply methods as in the case of RAM. We turn off the computer. Remove and reinsert the video card.

If it doesn't help and the BIOS beeps are repeated, you need to wipe the contacts with a grater and blow out the graphics adapter connector. Insert into place and turn on the computer.

Once you have taken out the video card, blow out the heatsink from dust and check that the fan rotates freely and easily. Inspect the graphics adapter for visible defects: swollen caps, discoloration of the PCB or other elements.

If the system has built-in video, (in the processor or on the motherboard) try using it to make sure that the rest of the components are working. A sign that there is built-in video is the presence of video outputs on the motherboard. (Note: There are processors with a P at the end - such as the Core i5-3350P. They do not have a built-in GPU. That is, even if there are outputs on the motherboard, nothing will be shown)

If all else fails and the BIOS beeps persist, you need to replace the graphics adapter. As usual, borrow from a friend and try.

Faulty processor (CPU) or motherboard

Turn off your computer. Remove the cooler from the processor. Remove the processor. The instructions for the system (motherboard) board say how to do this.

Inspect the socket and processor for damaged pins. In case of detection of damage, you are unlikely to be able to hand it over to the service under warranty. Therefore, with improvised tools we try to align the contact. We assemble the system. Don't forget to replace the thermal paste and try.

If nothing happened and the bios beeps are repeated, we try to connect the processor to another system. (Maybe a friend or acquaintance has a computer with the same connector). If it does not work there, then the processor is faulty. If everything works there, then your motherboard is most likely faulty.

How to choose a processor - motherboard power supply (20 or 24-pin connector), disconnect the power from the processor (4 or 2x4-re or 8-pin connector). We take out the battery and if there is a jumper, we close the 2nd and 3rd contacts for 30 seconds. Put the jumper back in place, connect all the connectors and try to turn on the computer. If it helped, the computer should issue one short beep and it will load correctly.

In this case, it is necessary to monitor the mode in which the drives operate (usually it is ACHI, but it goes astray to IDE). If the computer beeps well, go into the BIOS and set the desired operating mode. You can see how to do this. Restart your computer. Otherwise, you will get a blue screen.

Conclusion

In this article, we have considered BIOS beeps popular manufacturers: AMI, Award and IBM. Now you need to listen carefully and identify the beep sound of the computer.

What BIOS is on the motherboard can be found in this article.

And most importantly. We have considered ways to resuscitate a computer, using which, in most cases, you will avoid going to service centers.

If you know more effective methods, please write about them in the comments. Wish you stable operation your computer!

Greetings, friends! Today I will tell you about BIOS beeps. You may have noticed that when you turn on your computer, it beeps or, in other words, beeps. In fact, this is beeping your computer's BIOS, thereby telling you if everything is fine with your computer or if there are any problems. Let's try to understand this topic in as much detail as possible.

What do BIOS beeps mean when you turn on your computer?

Whatever BIOS is installed on your motherboard, when you turn on the PC, you should hear one short beep. This means that everything is working fine and after it will start Windows boot. However, sometimes the opposite is true. The BIOS squeaks like crazy, and the computer either does not turn on at all, or else the inclusion ends on the very first black screen - the BIOS bootloader.

This is where today's knowledge will come in handy. Because by this beeping you can determine what exactly is out of order in your PC.

Well, have you already looked at what BIOS you have? Now you can look at the decoding of BIOS audio signals.

AMI BIOS beeps. Full transcript

1 short	Everything is working properly. Pay no attention to him.
2 short	The RAM is not working properly or is defective. Try to disassemble the system unit, remove the RAM from the slots and insert it back. Perhaps this will solve the problem. Otherwise, you will have to contact a service center or buy a new RAM.
3 short	Almost the same as 2 short beeps. Do the same as in the previous paragraph.
4 short	You have something wrong with the system timer on the motherboard. Try resetting BIOS to factory settings. If that doesn't help, then try replacing the battery, it's cheap.
5 short	One of the worst mistakes ever. Your CPU is faulty. A simple restart of the computer may or may not help.
6 short	Check if the keyboard is connected properly. If yes, but the BIOS still beeps, then you will either have to replace the keyboard or repair the connector on the motherboard.
7 short	It's also scary. The motherboard is faulty. And it would seem that 7 is a lucky number. Such a surprise.
8 short	Transcendent to your video card. Although, try to pull it out and insert it back into the slot, maybe that will help. In the same case, if the video card is integrated, you will have to replace the entire motherboard or take it to a service center. Although I would not advise, if they fix it, then not for long.
9 short	You need to update or flash the BIOS of your computer.
10 short	CMOS memory error. Take it to the service center, they will help you.
11 short	This error is also related to RAM.
1 long and 1 short	The power supply is not working properly (or not working at all, you know better).
1 long and 4 short	The video card is not connected. Have you forgotten anything?
1 long and 8 short	You have not connected a monitor or the video card has a problem with displaying images on the monitor.
3 long	RAM is not working properly.
5 short and 1 long	There is no RAM. Insert it please.
Infinitely long	This is either overheating of the computer, or problems in the operation of the computer's power supply. So the BIOS beeps, which has stress, shock and severe panic.

Decoding of BIOS AWARD audio signals

1 short	All in in perfect order, do not worry.
2 short	Minor error in BIOS settings. Enter BIOS settings and reset it to optimal settings or cancel your last setting if you remember what exactly you changed.
3 long	This is a keyboard. Try restarting your computer.
1 short and 1 long	RAM is not working properly. Disassemble the system unit, remove the RAM from the slots and insert it back. If the problem persists, then you will have to contact the service center or buy new RAM.
1 long and 2 short	Problems with the video adapter, or rather video memory. Perhaps everything will be fixed if you remove the video card from the slot and insert it back. If the video card is integrated, you will either have to switch to a discrete one or replace the motherboard.
1 long and 3 short	Keyboard connection error. Try another keyboard if you have one. If the BIOS keeps beeping, then most likely the problem lies in the motherboard.
1 long and 9 short	BIOS needs to be flashed. It's better to do it in service center if you're not sure you can handle it yourself. And then you can lose the motherboard forever.
Infinitely repeating short signal	Problems with the power supply. It is buggy and can burn other components of your computer.
Infinitely repeating long beep	BIOS AWARD beeps in this way if your RAM is damaged. Possibly just one of the bars. Try it one by one

Here's how Phoenix BIOS beeps in a special way

BIOS Phoenix squeaks a little differently than its counterparts. It is more melodic, if I may say so in this context. Phoenix BIOS dot beeps alternate with pauses between them. And absolutely all the signals of that BIOS are always short.

1-1-2,	BIOS detected errors in the operation of the central processor.
1-1-3	Error reading information from the CMOS memory of the motherboard.
1-3-2	Unable to run RAM test.
1-3-3, 1-3-4	One of the RAM controllers is damaged.
1-4-1,	These BIOS beeps indicate errors in RAM.
3-3-1	The battery on the motherboard is dead or low.
3-3-4,	BIOS errors indicating the incorrect operation of the video adapter.
4-2-3	Check keyboard connection.

BIOS does not beep when you turn on the PC

Quite often it happens that when you turn on the PC, the BIOS does not beep at all. Why? Depends on the specific situation. To be in the subject, first you need to know what a speaker is and why you need it.

What is a motherboard speaker?

Motherboard speaker is a miniature tweeter that warns the user of malfunctions in the operation of your computer even before it is turned on. In other words, the speaker is a means of displaying information about the state of the computer. Also, the speaker is a device that emits BIOS beeps!

Here is what the speaker looks like on the motherboard. It is he who helps to emit BIOS signals!

Some reasons why the PC may not beep at startup

It often happens that manufacturers budget computers(and not only budget ones) they either forget to install the speaker on the motherboard, or deliberately save on this spare part. Accordingly, the BIOS does not beep, because there is simply nothing to beep. If you urgently need to diagnose a problem with your computer, you can simply borrow a speaker from your friend for a day. Fortunately, pulling it out and inserting it will not be difficult for you.

Another reason why you may not hear BIOS beeps when you turn on the computer is that you accidentally touched it or pulled it, and it just detached a little. In this case, insert it more tightly and everything will squeak with you. By the way, there are also such motherboards in which the speaker does not disconnect at all.

BIOS does not beep on laptops, because the speaker is not installed on them for aesthetic reasons. Imagine if every time you turn on your laptop, it gave you a characteristic, high-frequency signal. It's annoying.

Especially if the wife is already asleep, and you decide to play tanks in secret, turn on your laptop, and here you are BEEEEEEE!!! The wife immediately woke up and filled you with a star. In general, the speaker is not so relevant on a laptop.

Although some laptops can output similar beeps through external speakers and even through headphones. Everyone who encounters this is trying to get rid of this squeak (peep) as soon as possible by any means.

Where and how to connect the speaker on the motherboard?

You will need to know this if you still decide to borrow the missing speaker from a friend or buy it. When you took the speaker out of a friend's motherboard, you should have noticed that the place of its connection is marked with characteristic inscriptions, most often it appears there speaker or spk or spkr. Polarity for the speaker does not matter, so you can connect the speaker accurately.

A few examples of motherboards with marked places for connecting a speaker.

Summarizing

The article turned out to be quite voluminous, but I hope it helped you understand today's topic. At a minimum, you can now connect the speaker to the motherboard and know why you need it. We also examined the decoding of sound signals for the main and most popular BIOS versions. If your BIOS version differs from those considered, then just specify your request in the search engine, for example " decoding sound signals BIOS IBM / DELL».
