1. What does the computer tell us when turned on? Does he say something? Have you noticed that when you turn on the computer there is a beep? The computer wants to tell you that everything is fine, I'm booting up, or if a sequence of many beeps and possibly not stopping, indicates that the computer is not working. These signals can be used to understand and carry out, let's say, superficial computer diagnostics. Beep tables and manufacturer name delivered below bios/ AWARD, AMI, IBM, AST, Phoenix, Compaq, DELL, Quadtel

    2. If there is no beep?

  2. If there is no beep when you turn on the computer? There are several possibilities why this might happen:
  3. 1.) There may not be a speaker through which your computer tells you post code beeps.
  4. 2.) Bios is damaged.
  5. 3.) In this case, you should judge by other visual actions of your computer. Say, as an example, does it turn on at all? =)
    6. If you do not have a sound signal when you turn on the computer, let's see why this happens? Write in the comment at the bottom of the page, what actions does the computer perform when it is turned on? What errors occur when you turn it on? Describe in more detail in the comments and your message will come to my phone, I will answer your questions.

    Help on how to understand the information in the tables below:

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

    I repeat, each BIOS manufacturer has its own sound signals
  7. At the end of the article I would like to offer you a repair service computer technology in Podolsk

Hello everyone! Probably many of you have encountered a situation where there is no signal on the monitor when you turn on the computer. Any PC user can face such a problem. But what could be the reason that the display, when starting the system unit, remains dark? What to do in such cases? We'll figure out.

If, when turned on, your computer boots up, makes normal sounds, a flashing red light on the front panel indicates ongoing processes, but there is no image, the operating system will boot and the computer will work normally, only you won’t be able to see it, as you won’t be able to use it. There are actually quite a few reasons that could be. Here are the main ones:

  • malfunction of the monitor itself;
  • there is no contact in the connector of the video card with the monitor cable;
  • "flew" BIOS;
  • problems with the RAM board;
  • faulty video card;
  • the motherboard is faulty;
  • The computer's power supply is faulty.

Consider how you can correct the situation or identify a breakdown in each of the cases at home.

Attention! All of the following actions should be performed only if system unit disconnected from power!

Faulty monitor

Unscrew the screws of the monitor plug from the connector that supplies a signal from the video card of the system unit, remove it. If the inscription “No signal” lights up on the screen (it may also be in English), then everything is in order with the monitor. If it burned down, then even this inscription would not show.

If you have the opportunity, try it. The easiest way to do this is with an HDMI cable.

Connector contact problem

The steps are the same as in the first case. The connector that goes from the video card to the monitor can be (in most cases) three types: VGA (blue), DVI (white-gray or black) and HDMI (black). You can read more about connectors and other monitor characteristics.

Loosen the connector screws, remove the plug, plug it back in and screw it back in. Turn on your computer. If it doesn't work, move on. Try plugging the cable into a different jack or use an adapter. Perhaps a banal cable replacement will help, ie. if possible, be sure to try another cord.

Perhaps we just met a loose connector, so press on the plug and see if there is a result.

BIOS problem

Otherwise software for the motherboard is called BIOS. If you have problems with it, you can easily reset it to factory settings.

Somewhere in the area of ​​\u200b\u200bthe video card slot (sometimes higher, sometimes lower - depending on the characteristics of the motherboard) there is a flat battery, from which the BIOS “feeds”. If this battery is already for a long time has not changed (4 or more years), you can completely replace it with a new one. If the computer was purchased relatively recently, simply wring out the contact, remove the "tablet" of the battery from the connector.

To reset the settings, you can short-circuit the contacts with a screwdriver (+ to -) or wait ten minutes. Then put the battery back in and start the computer. If the image appears, the problem is fixed. If there is still no signal to the monitor, then move on.

RAM problem

Slots (connectors, in Russian) of RAM modules (boards) are usually located to the right of the processor (a massive square with a heatsink and a fan). In any case, you can't confuse them with any other boards. It can be one module for several gigabytes, or maybe several of 1 or 2 gigabytes.

Release the locks on both sides of the board, pulling it out of the slot. Clean the contacts well. For this, a regular student eraser (eraser) is suitable. Insert the module into place. Start the car. If the image appears, then the problem is fixed. If not, it would be a good idea to try replacing the RAM board with a new one. You can borrow it from friends for a while. Otherwise, you will never be sure that your RAM is “normal”.

It's easier when there are several boards. After removing and cleaning everything in turn, do not insert everything at once into place. Detect the non-working board by exclusion. Insert three, and then, in turn, change the boards. Inserted three, turned on the computer. The display is not working. Turned off the computer. They took one out, replaced it with another, turned it on again. If during these operations the display starts to show the load, the board that was not connected is the non-working board. It should be replaced with a new one.

In the end, try using a different slot if the specifications allow, as often the problem can be in it.

If everything remains unchanged and when you turn on the computer, the display remains dark, go ahead.

Video card failure

If the motherboard has a built-in video module, then you have a direct road to the service center. You cannot check it. If it is separate, you can replace it with another one. It happens that the built-in video module is low-power, and people purchase a separate, more powerful one. Although sometimes it will be enough to go through the contacts of the video card with a brush. There are times when the problem lies in the settled dust.

Disconnect the monitor cable from the video card connector. Remove the video card from its slot. To do this, you need to unscrew the fixing screw at the rear wall housing and squeeze the clip (plastic lock) on the right side (sometimes it may not be there).

Then connect the connector from the cable that goes to the monitor to the output of the integrated video card, located, as a rule, above. It is the same color and the same shape. Start your computer. If the image appeared, the problem was in the removed video card.

Attention! If you do not remove the additional video card from the slot, but simply switch the monitor cable to the built-in one, it will not work. The system will only launch the built-in module when it does not recognize another video card in the slot!

On motherboards without a built-in video module, you can identify a malfunction by replacing it with another one. Also, as in the case of an integrated video card, if people are not satisfied with the power of the video module and they buy a more powerful one. Replace it with the one that stood before. If the image went, your more powerful card "covered". If the display is “silent” further, then the problem is more global.

Conclusion

A malfunction of the motherboard or power supply can only be detected by handing over the equipment to a service center. Of course, it will not be difficult for “specialists” to get a power supply on the side and try it out by reconnecting all the connectors. But it is better to entrust these procedures to real masters. But just never contact the ad masters! This is such a game. They will rip you off at exorbitant prices, and the repair will be dubious.

Well, this concludes my article. I hope that it was useful for you and the information presented in it helped you deal with the problem. Don't forget to subscribe to my blog and also to my social networks. Good luck to you. Bye Bye!

Sincerely, Dmitry Kostin.

The harsh sounds of a speaker found on a computer motherboard always scare us. And even more so they make the average PC user think if they accompany a stopped download. To do this, I wrote an article about this, since it is important to know the meaning of all these sounds when the computer boots up, as they will help you determine the reason for the boot to stop.

It is worth noting that minor problems may arise with determining the cause, since there is no single standard for all manufacturers. There are at least three standards: Award BIOS, AMI BIOS and Phoenix BIOS - and that's not counting the ability of some manufacturers to set their own standards.

The official website of the manufacturer will help you determine the type of BIOS on your motherboard. We will analyze the standard Award BIOS, since they are more popular than labor:

  • 1 short beep - everything is in order with your computer and it is ready to start;
  • 2 short beeps means minor errors. The system will prompt you to enter the settings menu to correct the situation. With such a signal, you should check the fastening of the cables to the motherboard and hard drive;
  • 3 long beeps - keyboard controller malfunction. If the problem persists after a reboot, then the motherboard may need to be replaced;
  • 1 long and 1 short signals - problems with RAM. Check the fastening of the boards to the motherboard, as well as the operation of each module individually. You can also check the operation of the system with other modules;
  • 1 long and 2 short - problems with the video card. Remove the board and re-insert, and also check the monitor connection;
  • 1 long and 3 short beeps - problems with keyboard initialization. Check the connection between the keyboard and the motherboard. It is possible that your keyboard is out of order;
  • 1 long and 9 short signals - an error in reading data from CMOS - the memory in which BIOS settings. Reboot the computer, if the problem persists, then if your board supports flashing, you can update it;
  • 1 long repeated beep - an error when installing memory modules. In most cases, it is solved by installing modules again;
  • 1 short repetitive signal - a problem with the power supply. Often occurs due to accumulated dust.

This article will also be useful for those who:

  • sounds when turning on the computer
  • beeps when turning on the computer
  • sound when turning on the computer
  • three beeps when turned on
  • beeps when turning on the computer
  • beeps when booting the computer
  • computer beeps
  • beep when you turn on the computer
  • when you turn on the computer signal
  • long beep when turning on the computer

I am often asked what it means BIOS beeps when PC is turned on. In this article, we will take a closer look at BIOS sounds depending on the manufacturer, the most likely errors and how to fix them. In a separate paragraph, I will tell 4 simple ways how to find out the manufacturer of the BIOS, and also let me remind you of the basic principles of working with hardware.

Let's get started!

1. What BIOS beeps are for

Every time you turn it on, you hear the computer beeping. Often this is the one that is heard from the speaker of the system unit. It means that the POST diagnostic program completed successfully and did not find any problems. After that, 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 a bug, it's just that the manufacturer of your device decided to save money.

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

If problems are detected, the computer will emit an appropriate beep - a certain sequence of long or short beeps. You can decipher it using the instructions for the motherboard, but who among us keeps such instructions? Therefore, in this article, I have prepared tables for you with the decoding of BIOS sound signals that will 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 remove the power plug from the socket.

2. How to find out the BIOS manufacturer

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

2.1. Method 1

You can make identification different ways, simplest - look at the screen while loading. At the top, the manufacturer and BIOS version are usually indicated. To capture this moment press the Pause key on your keyboard. If instead of the necessary information you see only 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 BIOS manufacturer - use the Windows + R hotkeys and enter the MSINFO32 command in the Run line that opens. Thus it 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 "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 BIOS manufacturer using CPU-Z

3. Decoding BIOS signals

After we have figured out the type of BIOS, you can begin to decipher the sound signals, depending on the manufacturer. Consider the main ones in the tables.

3.1. AMI BIOS - beeps

AMI BIOS (American Megatrends Inc.) since 2002 is 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:

Signal type Decryption
2 shortRAM parity error.
3 shortError of the first 64 KB of RAM.
4 short
5 shortCPU failure.
6 shortKeyboard controller error.
7 shortMotherboard failure.
8 shortVideo card memory failure.
9 shortBIOS checksum error.
10 shortUnable to write to CMOS.
11 shortRAM error.
1 dl + 1 boxComputer power supply failure.
1 dl + 2 kor
1 dl + 3 korVideo card error, RAM malfunction.
1 dl + 4 korThe video card is missing.
1 dl + 8 korThe monitor is not connected, or problems with the video card.
3 longRAM problems, test ended with an error.
5 cor + 1 dlThere is no RAM.
ContinuousProblems with the power supply or overheating of the PC.

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 from the guys from your provider's technical support, but it really helps! However, if after the next reboot, squeaks are heard 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 startup. What do other sounds mean? Let's look at the table:

Signal type Decryption
1 recurring shortProblems with the power supply.
1 repetitive longRAM problems.
1 long + 1 shortRAM failure.
1 long + 2 shortVideo card error.
1 long + 3 shortKeyboard problems.
1 long + 9 shortError reading data from ROM.
2 shortMinor malfunctions
3 longKeyboard controller error
continuous soundPower supply defective.

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, pause, another beep, another pause, and two beeps.

Signal type Decryption
1-1-2 CPU error.
1-1-3 Unable to write to CMOS. Probably the battery on the motherboard is dead. Motherboard failure.
1-1-4 Invalid BIOS ROM checksum.
1-2-1 Faulty programmable interrupt timer.
1-2-2 DMA controller error.
1-2-3 Error reading or writing DMA controller.
1-3-1 Memory refresh error.
1-3-2 RAM test does not start.
1-3-3 Faulty RAM controller.
1-3-4 Faulty RAM controller.
1-4-1 RAM address bar error.
1-4-2 RAM parity error.
3-2-4 Keyboard initialization error.
3-3-1 The battery on the motherboard is dead.
3-3-4 Video card failure.
3-4-1 Video adapter failure.
4-2-1 System timer malfunction.
4-2-2 CMOS termination error.
4-2-3 Keyboard controller failure.
4-2-4 CPU error.
4-3-1 Error in RAM test.
4-3-3 Timer error
4-3-4 RTC error.
4-4-1 Serial port failure.
4-4-2 Parallel port failure.
4-4-3 Coprocessor malfunction.

4. The most popular BIOS sounds and their meaning

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

  • one long two short BIOS beeps- 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 can be banal dust that has clogged into the cooler. But back to the problems with the video card. Try pulling it out and cleaning the contacts with an eraser. It will not be superfluous to make sure that there are no debris or foreign objects in the connectors. Does the error still occur? Then the situation is more complicated, you will have to try to boot a computer with an integrated "vidyuha" (provided that it is on the motherboard). If it boots up, it means that the problem is in the removed video card and you can’t do without replacing it.
  • one long BIOS beep on power up- Possibly memory problems.
  • 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. It is also possible. If the RAM modules are working, the computer will boot.
  • 5 short BIOS beeps- Faulty processor. 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 squeaks like a cut, then you need to check whether the contacts are clean and even.
  • 4 long BIOS beeps- low speed or stop of the CPU fan. You need 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 problems with RAM, 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 too short- you need to count exactly how many short signals.
  • Computer won't boot and no BIOS signal- the power supply is faulty, the processor is not working properly, or the system speaker is missing (see above).

From my own experience, I can say that quite often all problems with loading a computer are due to poor contact between various modules, such as RAM or a video card. And, as I wrote above, in some cases a regular reboot helps. Sometimes you can solve the problem, or by resetting the system board settings.

Attention! If you doubt your abilities, it is better to entrust the diagnosis and repair to professionals. You should not take risks, and then blame the author of the article for what he is not guilty of :)

  1. To solve the problem, it is necessary pull out the module from the connector, remove dust and reinsert. Contacts can be carefully cleaned and wiped 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 in full view.
  3. Let me also remind you that any manipulations with the system unit should be performed only when power off. Don't forget to remove 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 pins of the microcircuit.
  5. Do not use metal and abrasive materials to clean the contacts of the RAM or video card modules. For this purpose, you can use a soft eraser.
  6. sober evaluate your possibilities. If your computer is under warranty, it is better to use the services of specialists service center than to delve into the “brains” of the machine on your own.

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

It happens that our "iron comrade" stops working. To preliminarily determine the cause of a computer's inoperability, motherboards are equipped with a speaker, a small speaker that tells us about errors.

It looks like this:

Or on the motherboard there is a connector for connecting a speaker (speaker). Many consider it superfluous, so they just take it off. I would not recommend you do this.

During the initial boot of the computer with the help of programs recorded in the BIOS, a self-test occurs. If the POST fails, the BIOS can provide information that helps identify the cause of the failure. In addition to displaying a message on the monitor, an audio signal is used, which is reproduced using the built-in speaker (speaker). Beep pitch, duration, and combinations may vary depending on manufacturer and BIOS version.

First you need to determine which BIOS your Vaas has. This is necessary because PCs with different BIOSes have different signal encodings.

How to determine which BIOS you have?

When the computer boots, the first thing that appears on the screen is the name of the BIOS. If you do not have time to look, go to CMOS SETUP using the DEL (Delete) key. Usually the BIOS brand is written at the top. If your monitor refuses to display an image on the screen, you will have to climb inside the PC and look for the BIOS chip on the motherboard.

What do beeps mean when you turn on your computer?
