The BIOS signaling system is a very good thing from the point of view of computer diagnostics. And almost always, when nothing is displayed on the screen by the number and type of signals from the system speaker (provided, of course, that it is connected), you can determine what the problem is and in which direction to start digging.

What do 1 long 2 short beeps mean when starting the computer?

So, if your computer, when turned on, does not display an image on the monitor, and the system unit beeps one long and two short signals, then in most cases the problem lies in the video card or its connector on the motherboard.

Less commonly, depending on the manufacturer BIOS problem maybe in random access memory.

There are also known cases when the motherboard did not support the processor installed in it at the BIOS level and was signaling a well-known sequence of signals.

Solution

The first thing to start deciding this problem This is the removal and re-installation of the video card from its slot with wiping of the contacts on it.

Installation of removing a video card to solve the problem of one short and two long BIOS beeps when turning on the computer

If you do not have an external video card installed, but use a built-in one, then try to install an external one, having previously taken it from someone. It is possible that the built-in video card is out of order.

Remember to do a visual inspection motherboard for swollen capacitors. If they are, then most likely they will be the culprit.

Reason 1 long 2 short BIOS beeps - swollen motherboard capacitors

Next, what needs to be done to solve the problem of 1 long and 2 short signals when starting the computer is to pull out and insert back the RAM. Moreover, if there are several memory sticks, then it is advisable to try each of them in different slots separately. At the same time, on each memory strip, we also wipe the contacts with an ordinary stationery eraser.

From possible reasons this sequence of signals - random access memory

If you hear this combination after all the above actions and this happened immediately after installing a new processor or assembling a new computer, then it is very likely that the problem is the incompatibility of the processor, video card or memory with motherboard... To check this, you need to go to the official website of your motherboard manufacturer and look at the processor and RAM in the compatibility list.

If none of the above helped, write your problem in the comments.

Sooner or later, most users personal computers Problems may arise when, when the computer is turned on, it emits any sequence of signals other than one short one, which signals the successful testing of all components of the computer. And this time we will consider a situation when the computer emits 1 short and 1 long beeps when turned on, while nothing is displayed on the monitor.

Causes of occurrence

As already mentioned many times, for each BIOS manufacturer, the same sequence of signals can mean different things.

AWARD BIOS

If you have an AWARD BIOS, then this sequence indicates that you have problems with RAM.

AMI BIOS

In the AMI BIOS, one long and one short beep when turned on indicates a problem with the power supply.

How to eliminate 1 short 1 long BIOS beep when turned on?

In order not to bother with determining the BIOS manufacturer, the first thing to start solving this problem is to try to get the RAM and install it back, preferably in another slot, after wiping the contacts with a stationery eraser.

One of the possible reasons for this sequence of signals is RAM.

If the problem persists, then try changing the power supply to a known working one by borrowing it from friends or neighbors.

Power supply one of the possible reasons 1 short 1 long BIOS signal

If, after all the actions done, the computer still emits 1 short and 1 long signals, then it is very likely that there are problems with the RAM board itself, the RAM connector on the motherboard or the motherboard itself.

It starts with diagnostics. You can often use the diagnostic tools of the PC itself, or rather the BIOS. If everything is in order, 1 signal is sent to the speaker. If earlier, during normal operation, you also did not hear any signals from the speaker, then you need to check whether it is in the system unit at all. In most cases, it looks like this:

If you hear multiple beeps, there is most likely a hardware error. A specific error is indicated by a combination of speaker signals. Depending on the manufacturer of the BIOS "and they may differ from each other. Before decrypting the signals, you need to find out which BIOS on your motherboard. This can be done in several ways:

1. View the documentation for the computer, namely the instructions for the motherboard.
2. View the name at boot or by going into the BIOS setup.
3. Open the lid system unit and read the name of the BIOS chip.

When the manufacturer finds you can check the combination of the speaker published with the data in the tables below:

Very often they ask me what they mean BIOS beeps when turning on the PC... In this article, we will take a closer look at the BIOS sounds depending on the manufacturer, the most likely errors and how to fix them. As a separate item, I will tell you 4 easy ways how to find out the manufacturer of BIOS, and also remind basic principles work with "hardware".

Let's get started!

1. What are BIOS beeps for?

Every time you turn it on, you hear the computer beeping. Often it is, which is heard from the speaker of the system unit. It means that the POST self-test diagnostic program has completed the test successfully and did not find any malfunctions. Then the download of the installed operating system.

If your computer does not have a system speaker, then you will not hear any sounds. This is not an indicator of an error, it is just that your device manufacturer decided to save some money.

Most often, I observed this situation with laptops and DNS stations (now they release their products under the DEXP brand). "What is the threat of the lack of dynamics?" - you ask. It seems like this is such a trifle, and the computer works fine without it. But if it is impossible to initialize the video card, it will not be possible to identify and fix the problem.

If a problem is found, the computer will issue an appropriate sound signal- a certain sequence of long or short squeaks. Using the instructions for the motherboard, you can decrypt it, but which of us stores such instructions? Therefore, in this article, I have prepared tables with decoding of BIOS beeps for you to help you identify the problem and fix it.

In modern motherboards, the system speaker is built-in

Attention! All manipulations with the hardware configuration of the computer should be carried out if it is completely disconnected from the mains. Before opening the case, be sure to disconnect the power plug from the socket.

2. How to find out the BIOS manufacturer

Before looking for a decryption of computer sounds, you need to find out the BIOS manufacturer, since their sound signals differ significantly.

2.1. Method 1

You can make "identification" different ways, simplest - look at the screen at the time of loading... The manufacturer and version of the BIOS are usually indicated at the top. To have time to fix this moment, press the Pause key on your keyboard... If instead of the necessary information you only see the splash screen of the motherboard manufacturer, press Tab.

The two most popular BIOS manufacturers are AWARD and AMI

2.2. Method 2

Go to BIOS... I wrote in detail about how to do this. Browse the sections and find the item - System Information. The current BIOS version should be indicated there. And at the bottom (or top) of the screen, the manufacturer will be indicated - American Megatrends Inc. (AMI), AWARD, DELL, etc.

2.3. Method 3

One of the most quick ways find out the manufacturer of the BIOS - use the hotkeys Windows + R and in the "Run" line that opens, enter the command MSINFO32. Thus will be launched System Information utility, with which you can get all the information about the hardware configuration of the computer.

Launching the System Information Utility

It can also be launched from the menu: Start -> All Programs -> Accessories -> System Tools -> System Information

You can find out the BIOS manufacturer through the "System Information"

2.4. Method 4

Use third party programs, they were described in detail in. Most often used CPU-Z, it is absolutely free and very simple (you can download it on the official website). After starting the program, go to the "Board" tab and in the BIOS section you will see all the information about the manufacturer:

How to find out the BIOS manufacturer using CPU-Z

3. Decoding of BIOS signals

After we have figured out the type of BIOS, you can start decoding the audio signals depending on the manufacturer. Let's consider the main ones in the tables.

3.1. AMI BIOS - beeps

AMI BIOS (American Megatrends Inc.) since 2002 is the most popular manufacturer in the world. In all versions, the successful completion of the self-test is one short beep , after which the installed operating system is loaded. Other AMI BIOS beeps are listed in the table:

No matter how trite it may sound, but I advise my friends and clients in most cases turn off and turn on the computer... Yes, this is a typical phrase of the guys from your provider's technical support, but it helps! However, if, after the next reboot, squeaks are heard from the speaker, which are different from the usual one short beep, then you need to eliminate the malfunction. I will talk about this at the end of the article.

3.2. AWARD BIOS - signals

Like AMI, one short beep AWARD BIOS signals a successful self-test and the start of the operating system. What do the other sounds mean? We look at the table:

3.3. Phoenix BIOS

PHOENIX has very characteristic "beeps", in the table they are written differently from AMI or AWARD. In the table, they are indicated as combinations of sounds and pauses. For example, 1-1-2 will sound like one beep, a pause, another beep, another pause, and two beeps.

4. The most popular BIOS sounds and their meaning

I could make for you a dozen more different tables with decoding of beeps, but I decided that it would be much more useful to pay attention to the most popular BIOS sound signals. So, what users are most often looking for:

• one long two short BIOS signal - almost certainly this sound does not bode well, namely, problems with the video card. The first step is to check if the video card is fully inserted into the motherboard. Oh, by the way, how long have you been? After all, one of the reasons for problems with loading may be commonplace dust that clogs into the cooler. But back to the problems with the video card. Try pulling it out and cleaning the contacts with an eraser. Make sure there are no debris or foreign objects in the connectors. Still getting an error? Then the situation is more complicated, you will have to try to boot the computer with an integrated "vidyuha" (provided that it is on the motherboard). If it boots, then the problem is in the removed video card and you cannot do without replacing it.
• one long BIOS beep on power up- possibly problems with RAM.
• 3 short BIOS beeps- RAM error. What can be done? Remove the RAM modules and clean the contacts with an eraser, wipe with a cotton swab moistened with alcohol, try to swap the modules. You can also. If the RAM modules are working, the computer will boot.
• 5 short BIOS beeps- the processor is faulty. A very unpleasant sound, isn't it? If the processor was installed for the first time, check its compatibility with the motherboard. If everything worked before, but now the computer beeps like a cut, then you need to check if the contacts are clean and whether they are even.
• 4 long signal BIOS- low speed or stopping the CPU fan. It is necessary to either clean it or replace it.
• 1 long 2 short BIOS beeps- problems with the video card or malfunction of the RAM connectors.
• 1 long 3 short BIOS beeps- either problems with the video card, or RAM problems, or keyboard errors.
• two short BIOS beeps - see manufacturer for error.
• three long BIOS beeps- problems with RAM (the solution to the problem is described above), or problems with the keyboard.
• BIOS signals are many short- you need to count how many short signals.
• the computer does not boot and there is no BIOS signal- the power supply is faulty, the processor is working, or the system speaker is missing (see above).

From my own experience, I can say that quite often all problems with loading a computer consist in poor contact of various modules, for example, RAM or a video card. And, as I wrote above, in some cases a regular reboot helps. Sometimes you can fix the problem, or reset the settings on the motherboard.

Attention! If you doubt your abilities, it is better to entrust diagnostics and repairs to professionals. You should not risk it, and then blame the author of the article for what he is not to blame :)

1. To solve the problem, you need pull out the module from the connector, remove the dust and insert it back. The contacts can be gently cleaned and rubbed with alcohol. It is convenient to use a dry toothbrush to clean the connector from dirt.
2. Don't forget to spend visual inspection... If some elements are deformed, have a black coating or streaks, the cause of problems with loading the computer will be at a glance.
3. Let me also remind you that any manipulations with the system unit should be performed only when the power is off... Remember to discharge static electricity. To do this, it will be enough to take hold of the computer system unit with both hands.
4. Dont touch to the conclusions of the microcircuits.
5. Do not use metal and abrasive materials to clean the contacts of the RAM or video card. For this purpose, you can use a soft eraser.
6. Soberly evaluate your capabilities... If your computer is under warranty, it is better to use the services of specialists. service center than to independently delve into the "brains" of the machine.

If you have any questions, ask them in the comments to this article, we will figure it out!

Let's consider what the speaker signals are, and what they notify about.
Speaker - a small speaker located on the base of the motherboard or less often displayed on the case of the system unit (connecting to the motherboard with two contacts of the plus - minus type. The speaker signals the operability (One short signal when turned on) - malfunctions (depending on which node is damaged. )

Consider signals and meaning - for example, the 3 most common systemsBIOS: Award; AMI; Phoenix.

Award BIOS version

AMI BIOS version

Phoenix version BIOS

Beep codes are represented by a sequence of beeps. For example, 1-1-2 means 1 beep, pause, 1 beep, pause, and 2 beeps.

Note! If there is no signal: there is no speaker; the built-in speaker is not defective; motherboard defect; BIOS failure (try and restart).

Instead of an afterword

If you observe one of the above malfunctions in the form of signals (except for a single short signal), contact the specialists of the service center for the repair and maintenance of computer equipment for help! Try to catch, any attempts self repair, tampering with faulty equipment can exacerbate the problem.
