Very often people ask me what they mean sound signals BIOS when turning on the PC. In this article we will take a detailed look at BIOS sounds depending on the manufacturer, the most likely errors and how to eliminate them. In a separate paragraph I will tell you 4 simple ways, how to find out the BIOS manufacturer, and also remind you of the basic principles of working with hardware.
Let's get started!
1. What are BIOS beeps for?
Every time you turn it on, you hear the computer beeping. Often this is heard from the speaker of the system unit. It indicates that the POST diagnostic self-test has successfully completed the test and has not detected any faults. After which 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 indication of an error, just that the manufacturer of your device decided to save money.
Most often, I observed this situation with laptops and DNS stationary systems (now they produce their products under the DEXP brand). “What is the danger of not having a speaker?” - you ask. It seems like such a small thing, 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 detected, the computer will emit a corresponding sound signal - a certain sequence of long or short squeaks. Using the instructions for the motherboard, you can decipher it, but which of us keeps such instructions? Therefore, in this article I have prepared for you tables with decoding of BIOS sound signals that will help you identify the problem and fix it.
Modern motherboards have a built-in system speaker.
Attention! All manipulations with the computer’s hardware configuration should be carried out if it is completely disconnected from the power supply. Before opening the case, be sure to remove the power plug from the outlet.
2. How to find out the BIOS manufacturer
Before looking for a decoding of computer sounds, you need to find out the BIOS manufacturer, since their sound signals are significantly different.
2.1. Method 1
You can make “identification” different ways, simplest - look at the screen while loading. The manufacturer and BIOS version are usually indicated at the top. To capture this moment, press the Pause key on your keyboard. If instead necessary information you see only the manufacturer's splash screen motherboard, 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 BIOS manufacturer - use the Windows + R hotkeys and enter the MSINFO32 command in the “Run” line that opens. This way it will be launched System Information utility, with which you can get all the information about the hardware configuration of your computer.
Launching the System Information utility
You can also launch it from the menu: Start -> All Programs -> Accessories -> System Tools -> System Information
You can find out the BIOS manufacturer through “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 BIOS section you will see all the information about the manufacturer:
How to find out the BIOS manufacturer using CPU-Z
3. Decoding BIOS signals
After we have found out the BIOS type, we can begin to decipher the sound signals depending on the manufacturer. Let's look at the main ones in tables.
3.1. AMI BIOS - beeps
AMI BIOS (American Megatrends Inc.) since 2002 is the most popular manufacturer in the world. In all versions, 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:
| Signal type | Decoding |
| 2 short | Parity error random access memory. |
| 3 short | Error in the first 64 KB of RAM. |
| 4 short | |
| 5 short | CPU failure. |
| 6 short | Keyboard controller error. |
| 7 short | Motherboard failure. |
| 8 short | Video card memory failure. |
| 9 short | Error checksum BIOS. |
| 10 short | Cannot write to CMOS. |
| 11 short | RAM error. |
| 1 dl + 1 cor | The computer's power supply is faulty. |
| 1 dl + 2 cor | |
| 1 dl + 3 cor | Video card operation error, RAM malfunction. |
| 1 dl + 4 cor | No video card. |
| 1 dl + 8 cor | The monitor is not connected, or there is a problem with the video card. |
| 3 long | Problems with RAM, test completed with error. |
| 5 cor + 1 dl | There is no RAM. |
| Continuous | Problems with the power supply or PC overheating. |
No matter how trivial it may sound, I advise my friends and clients in most cases turn off and turn on the computer. Yes, this is a typical phrase from the guys from your provider’s technical support, but it helps! However, if after the next reboot you hear squeaks from the speaker that are different from the usual one short beep, then you need to fix the problem. 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? Let's look at the table:
| Signal type | Decoding |
| 1 repeating short | Problems with the power supply. |
| 1 repeating long | Problems with RAM. |
| 1 long + 1 short | RAM fault. |
| 1 long + 2 short | Video card error. |
| 1 long + 3 short | Problems with the keyboard. |
| 1 long + 9 short | Error reading data from ROM. |
| 2 short | Minor faults |
| 3 long | Keyboard controller error |
| Continuous sound | The power supply is faulty. |
3.3. Phoenix BIOS
PHOENIX has very characteristic “beeps”; they are written in the table differently from AMI or AWARD. In the table they are indicated as combinations of sounds and pauses. For example, 1-1-2 would sound like one beep, a pause, another beep, another pause and two beeps.
| Signal type | Decoding |
| 1-1-2 | CPU error. |
| 1-1-3 | Cannot write to CMOS. The battery on the motherboard is probably dead. Motherboard failure. |
| 1-1-4 | Invalid BIOS ROM checksum. |
| 1-2-1 | The programmable interrupt timer is faulty. |
| 1-2-2 | DMA controller error. |
| 1-2-3 | DMA controller read or write error. |
| 1-3-1 | Memory regeneration error. |
| 1-3-2 | RAM test does not run. |
| 1-3-3 | The RAM controller is faulty. |
| 1-3-4 | The RAM controller is faulty. |
| 1-4-1 | Error address bar RAM. |
| 1-4-2 | RAM parity error. |
| 3-2-4 | Keyboard initialization error. |
| 3-3-1 | The battery on the motherboard is dead. |

| 4-4-2 | Parallel port problem. |
| 4-4-3 | Problems with the coprocessor. |
4. The most popular BIOS sounds and their meaning
I could make for you a dozen more different tables with beep decoding, but I decided that it would be much more useful to pay attention to the most popular BIOS sound signals. So, what do users most often search for:
- one long two short BIOS beeps– this sound almost certainly does not bode well for anything good, namely problems with the video card. The first thing you need to check is whether the video card is fully inserted into the motherboard. Oh, by the way, how long have you been here? After all, one of the reasons for problems with loading may be banal dust that has clogged up in the cooler. But let's return to the problems with the video card. Try pulling it out and cleaning the contacts with an eraser. It would be a good idea to make sure there is 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 a computer with an integrated video camera (provided that it is on the motherboard). If it boots, it means that the problem is in the removed video card and you cannot do without replacing it.
- one long BIOS beep at startup– 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, and try swapping the modules. Also possible. 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 this is the first time you installed the processor, check its compatibility with motherboard. If everything worked before, but now the computer beeps like crazy, then you need to check whether the contacts are clean and even.
- 4 long BIOS beeps– low speed or CPU fan stops. It needs to be either cleaned or replaced.
- 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 the manufacturer to clarify the 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 exactly how many short signals.
- The computer does not boot and there is no BIOS signal– the power supply is faulty, there is a processor performance problem, or there is no system speaker (see above).
From my own experience, I can say that quite often all problems with booting a computer are due to poor contact between various modules, for example RAM or a video card. And, as I wrote above, in some cases a regular reboot helps. Sometimes you can solve the problem by resetting the system board settings.
Attention! If you doubt your abilities, it is better to entrust diagnostics and repairs to professionals. There is no point in taking risks and then blaming the author of the article for something that is not his fault :)
- To solve the problem it is necessary pull out the module from the connector, remove dust and insert back. The contacts can be carefully cleaned and wiped with alcohol. To clean the connector from dirt, it is convenient to use a dry toothbrush.
- 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 in plain sight.
- Let me also remind you that any manipulations with the system unit should be performed only when power is off. Don't forget to remove static electricity. To do this, it will be enough to grasp the computer system unit with both hands.
- Dont touch to the pins of the microcircuits.
- Do not use metal and abrasive materials to clean the contacts of RAM modules or video cards. For this purpose, you can use a soft eraser.
- Soberly evaluate your capabilities. If your computer is under warranty, it is better to use the services of specialists service center than delving into the “brains” of the machine yourself.
If you have any questions, ask them in the comments to this article, we’ll sort it out!

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.

Separately, it should be noted that the BIOS continuous sound signals vary in tone. This could be caused by either a faulty power supply or an overheated PC.
Now you know about BIOS sounds and how to decipher them.
Have you noticed that when you turn on your computer, it makes a sound (squeak)? A special device is responsible for it, which connects to. It looks like this:
This “little thing” is called Speaker and its main purpose is to produce exactly this sound. To be more precise, when you turn on the computer (supply power), all equipment connected to the motherboard is checked. If everything is fine with it, then the speaker beeps once, and if not... then read the article and find out why it can beep more than once
Now, knowing this information, ask yourself the question “Is it worth turning off the sound when turning it on, if its purpose is to notify about a system test at startup?” But that’s exactly why you came here - to turn off this annoying beeper
But still, the essence of the article will be revealed, and it’s up to you to turn it off or continue to “tolerate” one sound signal when you turn it on.
The easiest way to turn it off is to unplug the sensor from the motherboard. It looks something like this:
This is if on a desktop computer. Laptops usually have these:
The method is effective, but not everyone will be able to do it for a number of reasons. Therefore, there are other ways to turn off the sound in Windows itself.
1) Launch and enter
sc stop beep
The sound will turn off, but only for the duration of the current session. And why is this necessary...
Therefore, it is better to immediately enter
sc config beep start= disabled
And nothing will beep when turned on.
Accordingly, in order to enable it again, you need to enter the same command, only instead of disabled it should be enabled
2) Launch the device manager
For Windows 7: Start - My Computer - RMB on an empty space and "Properties" - on the left "Device Manager"
For Windows 8 and 10: RMB on Start - Device Manager or similar with 7
Select from above View - Show hidden devices
Expanding the list " System devices", look for "Built-in speaker" there
and either hit it twice with LMB, or RMB and Properties To disable or remove it on the "Driver" tab:
If you do not have Built-in Speaker in the list, then most likely it is already disabled. And in general, the first method of muting the speaker is better. But the question is again - is it necessary?...
