There is no beep when turning on the computer. What to do if the computer starts beeping when turned on: signals when starting the computer

Hi all! 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 encounter this problem. But what could be the reason that the display remains dark when the system unit starts? What to do in such cases? We'll figure out.

If, when you turn on, your computer boots, 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, but you will not be able to see it, just as you will not be able to use it. There are actually quite a lot of possible reasons. Here are the main ones:

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

Let's look at how you can correct the situation or identify a breakdown in each case at home.

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

Monitor is faulty

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

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

Problem with contacts in connector

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

Unscrew the screws of the connector, remove the plug, insert it back and tighten it again. Turn on your computer. If it doesn't work, move on. Try inserting the cable into a different connector or use an adapter. Perhaps a simple cable replacement will help, i.e. If possible, be sure to try a different cord.

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

BIOS problem

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

Somewhere in the area of ​​the video card slot (sometimes higher, sometimes lower - depending on the characteristics of the motherboard) there is a flat battery, from which the BIOS is “powered”. If this battery has not been changed for a long time (4 or more years), you can completely replace it with a new one. If the computer was purchased relatively recently, simply release the contact and remove the coin cell 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 resolved. If there is still no signal to the monitor, then move on.

RAM problem

Slots (connectors, in Russian speaking) of RAM modules (boards) are located, as a rule, to the right of the processor (a massive square with a radiator and fan). In any case, they cannot be confused with any other boards. This could be one module for several gigabytes, or maybe several 1 or 2 gigabytes each.

Press the clasps on both sides of the board to pull it out of the connector. Clean the contacts thoroughly. A regular student eraser is suitable for this. Insert the module into place. Start the car. If the image appears, the problem has been resolved. If not, it would be good 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 one by one, do not put everything back in place at once. Identify the non-working board using the method of elimination. Insert three, and then, one by one, change the boards. We inserted three and turned on the computer. The display is not working. Turned off the computer. They took one out, replaced it with another, and turned it on again. If during these operations the display begins to show loading, the board that remains unconnected is the non-working one. It should be replaced with a new one.

In the end, try using a different slot if the characteristics allow, since this can often be the problem.

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

Video card malfunction

If the motherboard has a built-in video module, then you have a direct route to the service center. You won't be able to 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 over the contacts of the video card with a brush. There are times when the problem lies in settled dust.

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

Then connect the connector from the cable going to the monitor to the output of the built-in video card, which is usually located higher. It is the same color and the same shape. Start your computer. If the image appeared, the problem was with 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 the fault by replacing it with another one. Just 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 was there before. If the image goes, your more powerful card is “covered.” If the display continues to remain silent, then the problem is more global.

Conclusion

A faulty motherboard or power supply can only be identified by taking the equipment to a service center. Of course, it won’t be difficult for “specialists” to get a power supply from the outside and try it 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 wild thing. They will rip you off at exorbitant prices, and the repairs will be questionable.

Well, this is where I end my article. I hope that it was useful to you and the information presented in it helped you cope with the problem. Don't forget to subscribe to my blog as well as my social networks. Good luck to you. Bye bye!

1. What does the computer tell us when we turn it on? Is he saying something? Have you noticed that when you turn on your computer, you hear a beep? The computer wants to tell you that everything is fine, I’m booting, or if a sequence of many beeps and possibly non-stop signals indicates that the computer is not working properly. Based on these signals, you can understand and conduct, let’s say, a superficial diagnosis of the computer. Below are the tables of sound signals and the name of the manufacturer bios/ AWARD, AMI, IBM, AST, Phoenix, Compaq, DELL, Quadtel

What if there is no beep?

2. If there is no sound signal when you turn on the computer? There are several options why this could happen:
3. 1.) There may be no speaker through which your computer communicates post code beeps to you.
4. 2.) Bios is damaged.
5. 3.) In this case, you need to judge by other visual actions of your computer. Let's say, as an example, does it turn on at all? =)

If you don't get a beep when you turn on your computer, let's figure out why this happens? Write in the comment at the bottom of the page what actions does the computer perform when turned on? What errors occur when you turn it on? Describe in more detail in the comments and your message will be sent 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 computer equipment repair service in Podolsk

After you press the computer's power button, you hear a characteristic sound. It is supplied by the BIOS system upon successful completion of the self-test. This signal “says” that everything is fine with your PC, the system is ready to work. But what if there is no sound signal when you turn on the computer? Let's look together at the causes of the problem, consider expert advice on how to fix the problem, and also take a closer look at the BIOS signals - how they report a particular malfunction with their sounds. Shall we begin?

Characteristic signs of the problem

There is no beep when turning on the computer. Trouble, as they say, does not come alone. The problem itself rarely manifests itself. Most often it is accompanied by a black monitor - there are no images on the screen.

At the same time, you can hear how the computer coolers work properly. What could these signs mean?

What happened to the computer?

When you turn on the computer, there is no sound signal, and the device itself looks “dead” and does not react in any way to your manipulations?

Here is the consequence of the PC failing the self-test. If you haven’t opened the system unit before, then it can only mean one thing: your BIOS, the heart of the entire system, has been screwed up. Only a professional computer technician can deal with the problem and solve it.

But in any situation there are exceptions. Perhaps the problem is not that serious. Therefore, if there is no sound signal when you turn on the computer, you should not immediately rush to take the PC to a service center. First, you need to self-diagnose for more easily fixed problems.

Poor contact

Why is there no beep when I turn on my computer? It may be a bad connection in one of the connections. So check carefully:

• Are the computer mouse and keyboard connected well to the system unit?
• Is the monitor connector securely screwed in, etc.

Bad contact in itself is no joke. This problem can lead to quite sad consequences. It is a bad connection that can cause the following troubles: your processor, motherboard or monitor will burn out.

Video card malfunctions

Does your computer not beep when you turn it on? The system may not be able to pass the self-test due to some problem with the graphics card. Unfortunately, computers have not yet learned to respond properly to all possible scenarios of component failure. Therefore, such a sad answer may come out.

The BIOS self-test text was designed in such a way that a sequential check of all system components is carried out. And the video card is right at the very beginning of this list. It’s easy to check that the root of the problem lies precisely there: carefully remove the element from the system unit. Try turning on your computer after this.

If in response to these actions the BIOS deafens you with a squeak, then the problem is correctly identified - the video card is faulty. The issue can be resolved by replacing it with a similar working device.

It is much more difficult to deal with the problem if your computer has an integrated video card. After all, in this case you cannot do without a second device. If after installing the second video card the computer starts to turn on normally again, then the problem is clearly defined. Its root is in the integrated staffing system.

However, such a problem is not at all a reason to say goodbye to a computer that has a working motherboard and a perfectly functioning processor. As practice shows, with an external video card, a PC can last the user up to ten years!

Incorrect installation of equipment

When you turn on your computer, the BIOS sound does not turn on? Perhaps the source of the problem was your careless actions. This applies to those cases when you yourself replaced any components in the system unit.

How to understand that this is the problem? Turn off the computer, and then remove the newly installed equipment from the system unit. If the characteristic BIOS beep appears again when you turn it on, then the problem is your actions. Most likely, the new board is either faulty or incompatible with your computer.

BIOS update

No sound when you turn on your computer? Let's look at rarer, but still occurring cases. Sometimes the root of the problem is in the BIOS itself, namely in updating it. You may have equipped your PC with a new BIOS that is not compatible with your device.

How to avoid such trouble in the future? Pay attention to the test program, which is usually supplied with each BIOS equipment. Don't be lazy to run it on your PC.

Is the new BIOS fully compatible with your computer components? Don't rush to install it right away. First of all, protect your computer from sudden power outages. A UPS - uninterruptible power supply - will help you with this.

Why is this necessary? If the power supply stops while updating the BIOS on your computer, there is a 99.9% chance that the device will never turn on.

No internal speaker

How to make a BIOS sound when you turn on your computer? The user himself cannot configure this characteristic squeak and cannot activate it. The only thing that is possible is to turn on the melody when greeting Windows. But the OS interface settings have nothing to do with our problem.

So, you do not hear the characteristic BIOS signal when you turn on the computer. Moreover, the splash screen with the name of your motherboard did not appear, and there is no report message with the results of checking the system status. But at the same time you see the operating system greeting, the PC boots normally.

What it is? Your computer is functioning normally! We have a “false alarm” before us. The problem is that the PC does not have an internal speaker. This does not prevent it from functioning normally, but it can become a source of problems in the future. After all, it is through this speaker that the BIOS reports normal operation or certain system problems. With such an omission, you should contact the assembler of your system unit. Most likely, he simply forgot to install the beeper.

What is POST?

Let's now get acquainted with the test, the successful completion of which is indicated by this signal. Power-On-Self-Test is a diagnostic system self-test program that is stored in the BIOS ROM.

POST is designed to check all the most important components of the system:

• CPU;
• RAM;
• motherboard chips.

Information about the completion of the test is, accordingly, announced through the internal speaker of the system with a certain sound signal. If any of the components is inoperative, a specific series of long and short beeps will be issued. After this, most likely, the computer will turn off automatically.

What should be done in this case? Listen carefully to the signal and remember, write down the sequence of short and long beeps. If you did not have time to do this, then turn on the computer 30 seconds after its automatic deactivation. The signal will repeat.

What to do next? Refer to your motherboard manufacturer's instructions. Most likely, it will contain a table with a decoding of the BIOS signal. Such information is also available on the official websites of motherboard manufacturers. Decoding the signal will help you find out for yourself what is wrong with your computer, which of its components is faulty.

IBM BIOS Signals

Each motherboard model usually has its own decryption table. Unfortunately, there is no universal one. As an example, we will present the most common one - IBM BIOS. The sounds when turned on are as follows:

• One short signal - the test was completed successfully.
• There is no signal - the power supply is damaged.
• Continuous beeping - the power supply is damaged.
• Repeated short beeps indicate problems with the power supply.
• Long and short beep - motherboard malfunction.
• A short signal coupled with a black screen means the video card is damaged.
• A long signal and two short ones means problems with the video system.
• A long signal and three short ones means problems with the video system.
• Two short beeps - the monitor is not connected.
• Three long beeps - the motherboard is faulty, a keyboard controller error has been detected.

The usual beeping sound from the internal speaker when you turn on your computer is an important signal that tells you that your PC is working properly and is ready to work. If there is no such sound message, then this may indicate a problem with the BIOS, or other malfunctions that we also considered. We advise you to find a table with signals on the motherboard manufacturer’s website in order to identify the problem in time and solve it.

This situation is undoubtedly one of the most common computer malfunctions associated with computer hardware. Reinstalling programs and drivers will not fix it. Only reinstallation, repair or replacement of system unit components can help here.

In this article, we will tell you what you can try to do at home to fix the problem when there is no signal on the monitor when you turn on the computer.

Why might there be no signal?

The reason for this situation can be either a simple disconnection of the monitor cable or a breakdown of computer components such as the motherboard or video card.

And sometimes the problem appears due to a large amount of dust and the occurrence of “non-contact” and is solved by simply removing and replacing the part.

How to fix the problem?

You should start solving the problem with a missing signal on the monitor at home by checking the cable connection from the monitor to the system unit. Also check that the monitor's power cord is plugged into the outlet.

Checking Monitor Cables

If everything is fine with the wires, they are securely connected and have no visual damage, then you should try to remove the RAM, wipe the contacts with an eraser and put it back in place. Very often this helps and the computer turns on.

One possible reason is poor RAM contact

Also pay attention to whether the computer makes any beeps when you turn it on. If yes, then you can compare their sequence with to try to find the problem by the number of BIOS beeps.

Installing/removing a video card

The most common reason for no sound is turning it off or setting the volume to minimum. If there is no audio playing on your computer, hover over the speaker icon in the tray (right corner of the taskbar). The tooltip will indicate the current volume value. If the sound does not play in a separate application, check its settings. If it is enabled in the settings, audio playback in a specific program may be limited in the mixer. To check, right-click on the speaker icon and select “Open Volume Mixer.” There you can turn on the sound and adjust the volume level for each program running on the computer.

Check the volume on the playback devices themselves: headphones or speakers. When using speakers, also make sure they are connected to power and the power button is in the active position. Checking speakers or headphones is quite easy. To do this, just connect any other device to the audio output instead of a computer: a smartphone, a player.

Important! Also check your speaker settings. To do this, go to “Playback devices”, and in the context menu of speakers or headphones, click “Properties”.

Incorrect operation of audio drivers

Another common reason why there may be no sound on a computer is missing or damaged audio drivers. To identify this issue, hover over the audio icon in the tray. If the message “No audio output device is installed” appears, the problem is caused by the audio drivers.

To resolve these difficulties, right-click on the same icon and select “Detect sound problems” from the context menu.

This will open a troubleshooting window. Wait while the audio diagnostics run on your computer. Depending on the speed of the device, the process can take from a few seconds to a couple of minutes. If the determination of the cause of the malfunction stops at one place, click “Cancel”.

When the sound diagnostics are completed, the system will offer you a choice on which device you want to troubleshoot. In this case, you need to note the device used based not on its type, but on the location of the audio input. For example, if your speakers are connected through the audio input on the front of your computer, check the second box even though it says headphones.

If there is a hardware fault, the diagnostic result will be the following window. It may indicate damage to the speakers or headphones, but most often the cause of difficulties in the operation of audio devices is broken or damaged connecting cables.

At the last step of sound diagnostics, the result of its execution will be displayed. If the problems are resolved, close the troubleshooter. If the diagnostics did not help, click “View additional options.” You can also find help information about the causes of malfunctions by clicking on the “View additional information” link.

Incorrect connection or installation of the device

Sound may not work due to improper connection or installation of audio devices. To resolve this issue, check that the correct input is selected to connect your device to your computer. Speakers or headphones may be connected to the microphone input, causing them to not work.

Go to “Control Panel -> Device Manager” and check the status in the “Sound, Game and Video Devices” menu. If a yellow mark with an exclamation mark is displayed next to the name, the cause of the problem is incorrect installation or malfunction of the device

Note! If your audio hardware is not showing up in the manager at all, update the configuration in the Actions menu.

Right-click on your audio hardware and select Properties, then go to the Driver tab in the window that opens. To update the configuration, click the "Update" button. Here you can remove the driver to reinstall it later.

In the next step, select where you want to search for sound drivers. Two options are offered: automatic search, which includes a search on your computer and the Internet, as well as a simple search for drivers. It is recommended to select the first option to detect drivers.

Important! If the sound card is outdated and its driver is on a separate disk, first copy it to your computer.

The scanning will take about 20-30 seconds, after which a message will be displayed in the search window indicating the successful installation of new audio drivers. If the device already has the latest available driver installed, the configuration will not be updated.

If updating the drivers did not bring the desired result and the device still does not work, it is recommended to remove it from the system. To do this, right-click on the name and select “Delete”. Confirm the deletion in the dialog box by clicking "OK".

After this, you need to update the list of equipment in the “Action” menu. A search will be performed for devices connected to the computer. If the desired device does not appear after searching, restart the manager.

When the speakers are found, their installation will begin automatically. This process may take several minutes. When finished, a message will be displayed indicating that the speakers have been successfully connected and are ready to use.

Damage to connecting cables

Standard 3.5 mm connectors can fail as a result of mechanical damage. Typically, failure occurs at the base of the connector - at the junction with the audio cable. The break may also be in the cord itself. The cause of damage is most often pinched by furniture (table legs, chair wheels). The cable can also be chewed by pets. You can diagnose a breakdown visually or by connecting another cable to the speakers.

Physical breakdown of audio equipment

There may be no sound on your computer if the speakers or headphones you are using fail. This is not difficult to determine - just connect another audio device to the same audio input. If it works, the reason is the broken speakers, and not the computer settings.

Windows Audio Service Disabled

Another common reason for no sound is that the Windows Audio service is disabled. This background process is responsible for processing audio data and is always running by default on a running computer. But if you make changes to the system settings, the Windows Audio settings may be incorrect. The service can also be disabled by malware.
