The computer does not turn on, there is no squeak. When you turn on the computer, the system unit beeps and the monitor does not turn on. Diagnostics and Troubleshooting

Every technique will fail sooner or later. Regular PC users have already encountered such a situation when, when turned on. A number of questions immediately arise: What happened? How to fix it? Why is there a beep?

To answer these questions, you first need to understand which device is beeping. This is a speaker that is located in the system unit. The emitted squeak tells the user that the computer has experienced a hardware or software failure.

Usually, during a standard system boot, you can hear only one characteristic low squeak. In the event of a malfunction, there will be more of them. In the best case, when you turn on the computer, a black screen may appear on which you will see English letters and symbols. After reading them, you can understand the cause of the breakdown. There are times when the computer beeps, and the system cannot boot when turned on. Do not immediately despair, because in this way she herself gives us signals, warning us about the level at which the failure occurred.

What to do if the computer beeps and does not start:

Find out the BIOS version of your computer.
Calculate how many sounds the speaker produces.
According to the table, find your BIOS and see the number of squeaks, thereby you will determine the faulty device.
Ask friends for a similar part for a while and install it instead of the faulty one. In most cases, the computer should turn on without problems.

BIOS: concept and varieties

To determine the malfunction, you need to find out the BIOS version, which is a whole series of firmware for working with the computer hardware environment. There are several ways to find out the version. The most common, see the instruction manual. If it is not there, remove the cover of the system unit and look on the motherboard for a chip labeled Bios, where you will find its name. If a black screen lights up when turned on, then you can find out the BIOS version by the first entry, and you can also go to its settings by pressing the Delete key. There are several types: Award, AMI, Phoenix. These are just the most famous.

AWARD BIOS Signals

So, you have found out the type of BIOS for your system. Now it will not be difficult to find out the cause of the problem. Let's look at some signals:

Number of beeps	Description
1 short	Standard situation, no faults observed
2 short	Minor errors during loading, which are usually not serious. You can fix them through the CMOS Setup Utility. Loop fasteners should be checked.
3 long	Malfunctions in the keyboard controller
1 short, 1 long	Problem with RAM. Wipe the contacts of the RAM sticks
1 long, 2 short	Video card malfunctions. You should get it, first disconnect the power supply from the outlet, clean the contacts and return it back.
1 long, 3 short	Video memory failure
1 long, 9 short	Malfunctions when reading from ROM
Repetitive short	Power supply problem
recurring long	RAM problems
Repetitive high-low frequency	CPU issues
Continuous	Breakdown in the power supply. First you need to clean it from the accumulated dust. If this does not help, and the sounds are repeated, then it should be replaced.

AMI BIOS Signals

Missing and blank screen	Processor malfunction. Probably a contact is bent on the microcircuit. If the problem persists, the CPU needs to be replaced
Continuous beep	Power supply failure or computer overheating

Phoenix BIOS Signals

We will analyze the malfunctions of this system using signal codes. For example, the code 1 - 1 - 2 means: 1 signal, pause, 1 signal, pause, 2 signals.

Number of beeps	Description
1-1-3	CMOS memory not functioning properly
1-1-4	Invalid BIOS checksum. The chip may need to be re-flashed.

Troubleshooting without resorting to the BIOS

All of the above methods of troubleshooting the device are best done with the help of a competent specialist. However, in some cases, you can deal with it completely on your own. If your device beeps at startup, this does not always mean that a serious breakdown has occurred with it. You can check this by resorting to some simple methods:

check if all external devices are connected correctly: keyboard, mouse, printer, scanner;
turn off the power of the computer, check the connectors on the motherboard, remove the RAM modules, pull out the video card;
clean the motherboard from dust (using an air jet or a dry brush);
examine the motherboard for traces of burning (a characteristic smell is possible);
Replace all components removed from the computer and turn on the computer.

Perhaps the cause of the problem was excessive dustiness. As a rule, when you turn on the device, everything will be fine again.

conclusions

Many users have encountered a problem when the computer beeps and does not turn on. Why this happens, we discussed above. By checking the number and sequence of signals, you can independently determine the cause of the breakdown. But if you are still not sure about the correctness of your conclusions, then you should not resort to repairing the device yourself. You just need to contact a competent specialist.

Welcome to another article! The computer beeps and does not turn on. Probably, this question is common in various computer forums and social networks. Of course, this is not just a squeak, but alarms that warn you that a software or hardware failure has occurred.

Computer wizards will be able to understand by ear what exactly is bothering your PC or laptop. But professionals will ask for money even for a consultation. Why do you need this, if after reading this article, you yourself will be able to determine where the malfunction appeared on the computer. The most important task is to determine which BIOS you have. I will describe each BIOS, and also use an example to analyze the solution to the problem that the computer signals.

Computer beeps and won't turn on

The signals differ on different BIOS versions, if some have a common basis, then others, with the same sound, say completely different things. So, on computers that are not more than 10 years old, the following BIOS versions are used:

---->>> AWARD BIOS.

---->>> AMI (American Megatrends) BIOS.

---->>> Phoenix BIOS.

I have already talked about these BIOSes in more detail in one of my previous articles. Be sure to check out this article:

Here you will find a general concept, definition, about what BIOS is in general.

This is how the AWARD BIOS looks like - you can easily determine which version you have from the screenshots from this article.

Many users consider the AWARD BIOS to be a simple version - here I agree with them, since you can work with it quickly and, most importantly, conveniently. Before studying the signals, let's deal with entering the BIOS, because we need to determine the version. The activator button for almost all computers (stationary and laptops) is the "Del" key. We turn on the computer and immediately begin to click on it - usually several clicks are required, since the signal may not reach in one touch.

In rare cases, an alternative button is used to enter the BIOS. For example, on netbooks, this could be one of the "F" command keys. In any case, the system prompts us at the first seconds of loading.

In this case, "Del" is used to enter the BIOS. Take a close look at the bottom of the screen when booting to see which button is used to log in on your computer if the standard "Delete" does not fit.

Come in? Great, now compare your BIOS with screenshots to see which section of my article will be useful to you.

AWARD BIOS - meaning of signals

In addition to the characteristic design, the name at the top of the screen speaks of belonging.

So, the computer beeps and does not turn on. I propose to consider the meaning of signals when loading the operating system:

Two short beeps - errors in this case are not critical, their causes are misplaced date and time parameters in the motherboard itself, as well as problem cables. The time is lost due to a dead battery in the board - in this case, the signal can be ignored. If the download does not continue, check if the cables of hard drives and other units are tightly connected.

1 short- you hear this signal every time the computer boots up. If he is alone, then everything is working properly, you can be calm.

3 long- this signal indicates that the keyboard is either defective or incorrectly connected. Check if the contacts are securely connected.

Repeated repetition of one short signal - the power supply is partially faulty. First of all, try to clean it, it may just be clogged with dust. If that doesn't help, take it in for repair.

1 long, then 1 short- the signal indicates a malfunction in the RAM modules. Remove them from the motherboard, and then carefully clean their contacts, fit them tightly into the sockets.

1 long, then 2 short- the problem is related to the video card. Take it out, carefully examine it visually, if the contacts are not swollen, then clean it and put it back. If you have a laptop / netbook with a built-in graphics module, then you should take your computer for repair.

1 long, then 3 short- again a keyboard malfunction, or rather, a lack of initialization. Perhaps the problem is in the device itself, but just in case, it's worth checking if the keyboard is firmly connected to the computer.

1 long, then 9 short- When booting the computer, a failure occurred in the ROM. Rebooting the PC or laptop can sometimes correct the situation, in other cases it is necessary to change the firmware of the computer's permanent memory chip.

AMI BIOS - signal meaning

This is how the menu in ATI BIOS looks like, at the bottom there is a name: American Megatrends.

List of signals:

1 short - all units and software are working properly.

2 short ones - an error in the initialization of RAM modules. Open the cover and see if they are clogged with dust, clean the contacts. If the problem is not solved, then you should go to the workshop.

3 short - the fault also affects the RAM. Here, too, it is necessary to check the contacts and the correct installation of the “rulers” of RAM.

4 short - the signal indicates that the system timer has gone astray. Most users ignore this defect, as it does not interfere with work.

5 short - malfunctions in the processor. You won’t be able to solve the problem on your own, so I recommend that you immediately go to a computer workshop or service center.

6 short ones - a defect in the operation of the keyboard (in rare cases, problems are associated with the mouse).

7 short - the signal indicates that the motherboard is malfunctioning. Without additional equipment, it will be problematic to determine what the defect is, the conclusion is that we take the system unit or laptop for repair.

8 short ones - problems with graphics active adapters (in addition to the main video card, the motherboard has a built-in version).

9 short - a failure in the BIOS firmware. Sometimes the problem goes away after a reboot or after a Windows update.

10 short - the signal indicates an error in the CMOS memory.

11 short - if you counted exactly eleven signals, then the defect is in the cache. Need to clean it up.

1 long and 2, 3 or 8 short beeps inform the user that the video card is not connected to the computer correctly or is completely missing. I recommend that you check if the monitor plug is properly connected to the video card.

As you can see, in a more modern version of the BIOS, there are more signals, while they report a specific problem. AMI BIOS comes on modern computers, is currently considered the most stable version.

Phoenix BIOS - Meaning of Signals

"Phoenix" can be found on outdated machines, or rather, on motherboards. In any case, you can work with the Phoenix BIOS and, if you wish, even understand it, although it was difficult for me to perceive the signals of this version.

Here, the signals come in series, for example, “1 beep -1 beep - 3 beeps" means an error when recording or playing back CMOS information.

1 - 1 - 4: the data that is on the chip cannot be downloaded.

1 - 2 - 1: a fairly large range of errors in the operation of the motherboard. If the download does not continue, then you should immediately carry the computer to a service center.

1 - 2 - 2: The DMA controller is malfunctioning, sometimes cleaning the motherboard and reconnecting the plugs helps.

1 - 3 - 1: (3,4): error in RAM (random access memory).

1 - 4 - 1: This signal can indicate various problems related to the operation of the motherboard. The exact problem can only be determined at the service center.

4 - 2 - 3: incorrect or missing keyboard connection, check the contacts.

What to do if the computer beeps and does not turn on.

Usually, people only start noticing the beep when the computer stops booting. First of all, determine the signal, to help - the tables above for all BIOS versions.

There is a possibility that somewhere the socket has moved away from the hard drive or other aggregate part of the computer. Open the computer cover, then take a good look at all the "vital" elements on the motherboard. This is especially true of the hard drive, video card and RAM.

In general, for a better understanding of today's topic - The computer beeps and does not turn on, I recommend that you watch the following video:

If the problem is with the batteries, then you can try to replace it yourself. This is an ordinary battery, resembling a tablet in shape, which is located on the motherboard. It usually doesn't affect booting, it just tells you that the battery is low. If the download does not occur, while the signal indicates that the processor, RAM or other elements of the motherboard are not working properly, then you should immediately contact the professionals. Usually in such cases, the computer does not boot at all. Concluding today's article, I would like to recommend you to read the following article:

From this article you will learn what to do if the computer turns on, the fans are running, the lights are on on the system unit, but there is no image on the monitor, that is, in one word we can say that we see only a black screen on the monitor.

And that’s all for today, I hope the article was interesting for you. See you all in the next issue, dear friends!

Over time, any technique fails, and of course the computer is no exception. A user who has been working on a computer for more than a year knows that in the event of a hardware or software failure, the computer may refuse to work. For example, when the computer beeps and does not turn on, emitting incomprehensible signals for the user, before reaching Windows loading.

First, let's explain why the computer beeps when turned on. You must understand that the squeaks are emitted by the speaker, which is located in the system unit. And if you don’t know why the system unit beeps, then a little lower I will show a table by which you can see the reasons for this.

The computer can beep in different ways, emit one long beep, two short beeps, three short beeps, or even repeat short beeps 7 times in a row, etc. To determine what these signals mean, we will be helped by tables of sound signals for different types of Bios. Bios is located on the motherboard, which is located in the system unit.

When you turn on the computer, when a black screen appears, the equipment connected to the computer is checked. If all hardware is in working order and properly connected, Windows will boot. If your computer refuses to boot, then this article will help determine which computer hardware is out of order.

After you understand from the squeaks why the computer is beeping, you need to borrow this part from your friend and try to turn on your computer using the part from someone else's computer.

Let's repeat our steps if the computer does not start and beeps.

You need to turn on the computer and count how many squeaks the speaker emits.
See the version of your Bios when you boot your computer. Look for an inscription, Bios version or something like that. Usually the inscription is located at the very top.
Find the version of your BIOS and the number of signals in the table.
Next, find this part, connect it to the computer and turn it on. If the computer turns on, there are no squeaks, then you have solved the problem by almost 90 percent. It remains to find or buy a part in order to give the part to the person from whom you took it.

I think you understand, because it was stated as clearly as possible.

Note: signals are short, as well as long.

If you have a printer, it is better to print this article, suddenly at the wrong time your computer will not turn on and at the same time emit signals. In one article, I already touched on the BIOS topic: "".

When you turn on the computer, the system unit usually emits a squeak. This is a short single signal that indicates the performance of the equipment. But it happens that the computer makes an unusual sound, more prolonged or a few short ones. What does this say? The squeak is the result of hardware testing for the health of the system unit. But today we’ll talk about how to decipher this sound.

If the system unit beeps in the Award BIOS

So, if the system unit beeps when turned on, then this can indicate both that everything is in order, and that any of the parts is out of order. But in order to find out the meaning of the signal, first you need to determine the type of BIOS that is installed on the motherboard. This can be done by pressing the Del button on early boot. Also, if necessary, you can.

If the Award BIOS is on, then one signal, short in duration, as in other systems, indicates that everything is in order. The test passed successfully, the computer is ready to work. Some system units may not make any sounds at all. If, when you turn on the computer, one continuous long beep is emitted, then most likely the power supply is faulty. In this case, it will need to be replaced.

Two short beeps may indicate that minor errors have been detected. In order to fix them, try to check how well the cables are fixed in the hard drive and motherboard connectors. Three long beeps indicate that an error has occurred in the keyboard controller. You can try to fix it by restarting your computer. If this does not help, then you may need to replace the motherboard.

One long and two short beeps in the Award BIOS is the most common error. The signal indicates that there are problems with the video card. You can fix the situation by pulling out and reinstalling the motherboard. In addition, you should check the contacts of the video card, and how it is connected to the monitor. It is possible that this part will not need to be replaced.

Among the common problems that are easy to deal with on your own, you can note one short signal that repeats all the time. This indicates that there is a problem with the power supply. It is possible that you just need to remove the dust accumulated in it. This procedure should be done when disconnecting the computer from all power sources.

Signals for AMI BIOS

If it doesn’t squeak, and there is a black screen on the monitor in front of us, then most likely the breakdown is quite serious and you will have to turn to specialists. Most likely, in this situation, the malfunction is too serious. However, first check the connection to the monitor, as well as all other connection pins. If two short beeps sounded, then there may be a problem with the RAM. The modules will most likely need to be replaced. The same can be expected after three short beeps. First, try restarting your computer and see if the error is gone.

In the case when six short beeps sound, then the malfunction lies in the keyboard controller. First you need to check its connection with the motherboard. If nothing happened, then it is recommended to replace the keyboard. After that, you should check the performance of the system unit. In the case when the previous steps did not help, then most likely it is necessary to replace the motherboard.

Five short beeps are a sign that the problem is in the processor. It may need to be replaced. In this case, you will need to choose the right processor, you will learn how to do this. Seven short beeps indicate a malfunction of the motherboard. One long and two short beeps indicate problems with the video card. This is also indicated by one long and three short peeps, one long and eight short peeps. If a similar problem arose, first you need to check the connection of the video card to the motherboard. In the event that everything is in order, it is possible that this part will need to be replaced.

Signals for Phoenix BIOS

Many users are wondering why the system unit beeps periodically. As is clear from the above, the problem can be anything. The main thing is to correctly determine what exactly is the reason. So, for the Phoenix BIOS, one short, one long and three short beeps indicate that an error has occurred in the CMOS write. In this case, you will need to replace the memory chip. If this does not help, then a new motherboard will be needed.

Problems with the same component are indicated by signals produced according to the “1-2-1” scheme. Faults associated with RAM are also indicated by the squeak “1-3-1”. One long and eight short beeps indicate that the video adapter is not working. Another reason for such a signal may be that the monitor is not connected. Check the connection of all cables, then reboot the system unit.

Short beeps that are constantly repeated indicate that the power supply is not working properly. In order to fix this, you first need to check the performance of this part. In addition, see if the cords are broken, if the surge protector is working properly. If problems occur after that, you may still need to replace the power supply with a new one.

You can reset the BIOS by removing the battery. Another way is to use a special jumper, a jumper. You can find out where it is by carefully studying the instructions for the motherboard.

So, most of these problems can be solved on your own if you know exactly how to do it. For example, it is quite simple to check the connection of a monitor or keyboard to the system unit. It is also easy to replace the battery on the motherboard. However, if the problem is more serious, then it is better to initially turn to specialists if you are not confident in your abilities, so as not to aggravate it even more.

Many people already know that if the computer beeps when turned on, it means that it has malfunctions, determined by the type of sound. In this article, we will analyze how to properly analyze such audio signals.

Beep sounds when you turn on your computer are the primary indicator of computer operation. Each time you turn on the power of the PC, the BIOS performs a test of the main systems and components of the computer - the so-called Power On Self Test function is launched.

If the test is passed successfully, the system is OK, then one short beep is emitted, and the system boots up normally. If there are failures, problems in the PC components, then the computer emits a series of beeps of varying duration.

To understand what it means when the computer beeps when turned on, you need to find out which BIOS manufacturer's modification is installed on your PC.

Depending on the developer, sound signals can take on different meanings, which will indicate the culprit of the malfunction.

To find out the name of the BIOS manufacturer, immediately after starting the computer, press the “ DEL”, or “ F2". After completing these steps, you will enter the BIOS menu. At the top of the screen is the BIOS manufacturer's name.
