One long bios beep when turning on the computer. AMI BIOS beeps

Compared to AMI signals, audio signals Award BIOS are not so diverse, but in the vast majority of cases their set is quite enough to encode all possible errors motherboard. Distinctive Features Award BIOS makes extensive use of long beeps, as well as the use of types of signals such as continuous and constantly repeating beeps.

Below is a list of Award beeps and their corresponding problem situations, as well as possible ways their decisions.

• No signals

This may indicate a malfunction of both the power supply and the motherboard itself. In some cases, the system speaker of the motherboard may be faulty. To correct the situation, you can try checking the contact of the power cable coming from the power supply to the motherboard.

• One short

The user hears this signal most often. It means that the BIOS POST hardware check procedure was successful and the computer can continue booting.

• Two short

This message in Award BIOS is reserved for cases where the error is not serious and allows the computer to operate normally. normal mode. Detailed text message the essence of the error is displayed on the monitor screen. Further actions The user's steps to resolve the error usually depend on the type of situation. For example, the error may be caused by a dead CMOS memory battery. In such a case, it must be replaced.

• Short repeating

The signal indicates a faulty power supply or damage to the power circuits. To correct the situation, you can try checking the contacts of the wires coming from the power supply to the motherboard.

• One long and one short

Message indicating a malfunction random access memory or its absence altogether. If the latter option occurs, then the RAM modules must be installed, and if the memory is already present in the slots, then you can try to reinstall the RAM chips. If this does not help, then most likely the problem is a faulty memory module. Sometimes these signals can be generated when the video memory is faulty.

• Long repeating

An error similar to the previous one and indicating problems with RAM. This error most often occurs when incorrect installation memory modules. To correct the situation, you should check whether the modules are installed correctly, and if not, then reinstall them.

• One long and two short

Similar beeps indicate a video card error. Often in such a situation, the problem is simply a poorly installed graphics accelerator card in the expansion slot, although the cause may also be a faulty video card chip.

• Three long

This message means that the BIOS has detected a keyboard controller error. As in other cases, here you can try to check the connection between the keyboard and the system unit. In some cases, the signal disappears after reboot again computer. If the keyboard works, but the signals still remain, then they can usually be turned off using a special BIOS option.

• One long and three short

A sound message, like the previous one, indicating a keyboard error. But, unlike the previous error, in in this case the signals indicate that the error manifests itself in a slightly different situation - the BIOS detected the keyboard, but was unable to access it.

• One long and nine short

Signals indicate an error permanent memory CMOS. This failure It can be either random, disappearing after rebooting the PC, or be a consequence of a malfunction of the CMOS memory chip, as well as incorrect flashing of the BIOS.

• Repeating signal with high and low frequencies

Error indicating a malfunction or incorrect installation central processor. To correct the situation, you should try to check the reliability or correct installation of the processor and its fastening in the socket.

When you turn on the computer, the BIOS performs a process of diagnosing the hardware of the motherboard and all connected devices: processor, RAM, power supply, graphics subsystem and other devices. If, POST request performed incorrectly, a beep device plays a signal or group of signals in a certain sequence of tones. To test your computer at startup, you only need to know the following table of BIOS beeps.

The list is updated regularly.

Compared to other BIOS manufacturers' beep sounds, BIOS AMI beep sounds are more varied. In most cases, these beeps allow you to identify a malfunction during the computer boot stage and the POST hardware test procedure. Typically, all you need to do to determine which component is causing the problem is to count the number of beeps emitted by the system speaker.

Below are the beeps produced by the BIOS AMI. In all cases, the number of signals and their type (long/short) are indicated.

• No signals

This situation is perhaps the most unpleasant that a user can encounter. As a rule, it means that power is not supplied to the motherboard or the BIOS is generally faulty. No power to the motherboard usually means either a faulty/broken power cable or a faulty computer power supply.

• One short

The only one short signal- this is the same signal that all users are accustomed to hearing every time they start their PC. It means that no errors or problems were detected during the hardware check, and the computer can continue to boot.

• Long continuous

This signal means that the PC power supply is faulty. However, unlike the situation with complete absence signals, in this case power is supplied to the motherboard, but its parameters do not correspond to the nominal.

• Two short

This signal indicates an error in the RAM. This error may indicate either a malfunction of the memory modules themselves, or simply that one of the modules is poorly inserted into the slot.

• Three short

This type of signal also indicates an error in the RAM. But this error is quite specific and rarely encountered - it is an error in the first 64 KB of RAM.

• Four short

This signal indicates a system timer malfunction. Fortunately, this type of malfunction occurs infrequently, but it is not uncommon the only way The solution is to replace the entire motherboard.

• Five short

Similar BIOS image informs the user about heart failure personal computer– central processor. However, it is not always this malfunction may be due to a defect in the processor chip itself. Often, to fix the problem, it is enough to check that the processor is securely installed in the socket.

• Six short

This message indicates that the keyboard controller is faulty or that the keyboard itself is missing. Very often, to correct this situation, it is enough to check the contact in the keyboard connector on the system unit.

• Seven short

Such a set of sounds indicates a rather serious malfunction - namely, a failure of the system board. However, sometimes the error may disappear after checking the power cable contacts on system board.

• Eight short

BIOS message indicating video memory failure. But here, as with many other errors, sometimes the problem may simply be poor contact - in this case, between the motherboard slot and the video card.

• Nine short

In this case, the BIOS signals a checksum error. BIOS memory. The reasons for this phenomenon may be different - the error is in the new BIOS version or random CMOS memory failure. Often the problem can be fixed by flashing the BIOS.

• Ten short

With this set of signals, the BIOS reports a write error in CMOS memory. As a rule, this error is more serious than the previous one and often requires the intervention of a specialist from a service workshop.

• Eleven short

• One long, then two, three or eight short

This type information message tells the user that there are video card errors. Typically, such sound signals are only generated when using old video cards (Mono/CGA/EGA), so the chance of encountering them is currently extremely small. In most cases, this malfunction can be eliminated by carefully installing the video card in the connector.

Not everyone will think about what they mean BIOS beeps when we press the PC power button. It is the BIOS that causes such sounds, which can be short or long. Different types of BIOS have different sound signals, in this article I will try to talk about all of them, as well as solve some of the problems that accompany them.

Purpose of BIOS beeps

When you turn on your computer, you hear a squeaking sound. Usually it is short and comes out of the speaker located inside the system unit. Such a signal does not bode well and indicates that the program has successfully diagnosed the POST self-test, which is responsible for checking components for serviceability. If everything is fine, this will be the signal.

On some PC models, you may not hear anything at all, but this is only thanks to the manufacturer, who did not build a speaker into the computer. Unfortunately, the lack of a speaker is not good decision, since it will not be possible to determine a malfunction, for example, of a video card.

If some kind of malfunction occurs, you will hear a sound when you turn on the computer. There may be several of them, and they may be long, depending on what is faulty. Usually the instructions already have everything necessary information about BIOS signals, but if you don’t already have this guide, then read this article and perhaps you will find a definition of certain BIOS signals.

Recommendation! If you decide to look inside system unit, for example, to check the presence of a speaker, be sure to turn off the power to the PC, and do not try it immediately, but a few minutes after turning it off.

How can I find out who made the BIOS?

In this section, I will show you how to find out who made your motherboard BIOS firmware. You need to know this because different models Sound signals indicate various violations.

First option

The simplest thing you can do is turn on the PC and for a couple of seconds you will notice a window in which the BIOS manufacturer and some other parameters are already indicated. The most popular manufacturers are AMI And AWARD. There are, of course, others.

Second option

To do this, you need to find an item that shows information about the computer and the BIOS firmware itself. Usually the tab is called System Information.

Third option

Boot into Windows andOpen the window "Run" using keys Win+R. Enter the command there msinfo32. On the left you should be in the section "System Information". On the right we look at the point "BIOS version».

Fourth option

You can also use various utilities, for example, AIDA64 or CPU-Z. Free program CPU-Z has a tab "Pay", where you go. There is a subsection "BIOS" and all necessary information about him.

Using the AIDA64 program, go to the section "Motherboard" on the left and click on the item there "BIOS", all information about Bios will be listed there.

How to decipher BIOS beeps?

So, we figured out the BIOS manufacturer, now I will show the designation of beeps, but only for a few versions.

BIOS AMI beeps

One of the most famous companies American Megatrends Inc. Abbreviated as AMI BIOS. In 2002 it was already such. So, the normal beep is a short sound. It means that everything is fine, after which the OS will begin loading. Now let's look at other sounds.

Signal	Designation
Long continuous	The power supply is faulty, the computer is overheating.
Two short	RAM parity error.
Three short	Error in the first 64 KB of RAM.
Four short
Five short
Six short	Error in the keyboard controller.
Seven short	Problems with system board.
Eight short	Problems with video card memory.
Nine short	BIOS checksum error.
Ten short	CMOS recording is not possible.
Eleven short	RAM error.
1 long and 1 short	There's something wrong with the power supply.
1 long and 2 short	Problems with RAM or video card.
1 long and 3 short	Problems with the video card or RAM.
1 long and 4 short	There is no video card in the slot.
1 long and 8 short	Lack of monitor connection, something with the video card.
Three long	The test completed with an error, problems with RAM.
5 short and 1 long	There is no RAM module.

Sometimes the sounds are false; if you turn off the PC again and then turn it on, there is a possibility that such a signal will no longer appear. If you hear more than one short sound, but ones like those shown in the table, then you need to solve the problem.

Sound signals AWARD

The next popular manufacturer is AWARD. Let's consider its sound signals. Then someday I’ll write about everyone existing types BIOS, and I also recommend a book in which everything is described in great detail.

The normal sound signal, indicating the serviceability of all computer components, is still the same as in the first option - a short signal. The remaining sounds are listed in the table below.

Signal	Designation
Continuous signal	Power supply failure.
One short, repeats	There's something wrong with the power supply.
One long, repeating	Problems with RAM.
One long and one short	RAM malfunction.
One long and two short	Problems with the video card.
One long and three short	There's something wrong with the keyboard.
One long and nine short	Error reading data from ROM.
Two long	There are non-critical faults.
Three long

Phoenix beeps

In this type of BIOS, sounds are accompanied by pauses, that is, if 1 sound is heard, then there is a pause, then another sound, and another pause, and then two sounds, then the signal is recorded in the form of these very sequences of pauses and sounds - 1-1-2 . Now I will show this in the table.

Signal	Designation
1-1-2	Problems with the central processor.
1-1-3	CMOS recording is not possible. The CMOS battery is dead, which means it needs to be replaced. Problems with the system fee.
1-1-4	Unfaithful check sum BIOS ROM.
1-2-1	The programmable interrupt timer is faulty.
1-2-2	There is an error in the DMA controller.
1-2-3	There is an error in reading/writing the DMA controller.
1-3-1	Problems with memory regeneration.
1-3-2	The RAM test does not run.
1-3-3
1-3-4	The RAM controller is damaged.
1-4-1	IN address bar RAM problems.
1-4-2	RAM parity error.
3-2-4	There were problems initializing the keyboard.
3-3-1	The CMOS battery is dead.
3-3-4	Problems with the video card.
3-4-1	Problems with the video adapter.
4-2-1	Problems with the system timer.
4-2-2	Problems with CMOS completion.
4-2-3	Problems with the keyboard controller.
4-2-4	Error in the operation of the central processor.
4-3-1	RAM testing failed.
4-3-3	Errors in the timer.
4-3-4	Problems with RTC operation.
4-4-1	Problems with the serial port.
4-4-2	Parallel port problems.
4-4-3	Problems with the coprocessor.

The most common BIOS beeps

Of course, there are many more sound sequences for different BIOS types, and there would be much more tables here. Therefore, I decided to consider the most popular signals that most users encounter.

• 1 long and 2 short sounds– usually this signal indicates problems with the video card. Check whether the video card is inserted well into its slot, also do not forget that due to dust and dirt there may be problems with connecting devices, so it is better to clean everything. Take out the video cards, wipe the contact tracks with an eraser, and do it very carefully. Then put it back in. If the difficulty persists, then you can try inserting the video card into another slot or switching to the built-in one, provided that it is on the motherboard. It's about about integrated.

• 1 long sound- indicates a problem with the RAM.

• 3 short sounds– Again errors in the random access memory device. There is the following option - remove the RAM modules and clean the contacts, as well as the slots from dust and dirt, swap them, replace them with other RAM modules. Alternatively, you can reset the BIOS.

• 5 short sounds– this signal indicates a processor malfunction. It is possible that you purchased new processor, which is not compatible with your motherboard. Also check all contacts and clean any dust.

• 4 long sounds– the signal indicates problems with the cooling system, that is, with coolers. Perhaps they are completely faulty or work slowly. There are two options: clean them from dust, or change them.

• 1 long + 2 short sounds– a malfunction of the video card or from the RAM connectors.

• 1 long + 3 short sounds– may also indicate problems with the video card and RAM, or something with the keyboard. We'll have to check everything.

• 2 short sounds– I can’t say for sure, check your documentation. There may be a problem with the RAM.

• Several short sounds– just count how many sounds and see if such a combination is in the table.

• No PC boot and BIOS sound – if there is no sound, then most likely you do not have a speaker, or it is faulty. If the computer does not boot, check the power supply.

Tips for troubleshooting problems with your computer emitting BIOS beeps

I almost never had any components fail, and sound signals only appeared due to bad contact some components. For example, the RAM modules or video card were inserted poorly. Sometimes something just went wrong and simply restarting the computer helps. Sometimes it can help in solving problems altogether.

I want to say that I don't knowledgeable people you should not take any action. If you have friends who can help, then contact them, or go to the service.

1. Sometimes you can correct the situation like this: remove some component and wipe its contact from dust, and also blow out the connector. Then put everything back in. You can clean the contacts with alcohol and a dry cloth or an eraser.
2. Look at all the components and elements located inside the system unit. Is there a smell of burnt components? swollen capacitors, oxide and other bad phenomena.
3. Before you climb inside the system unit, disconnect it from the power supply, and also remove static electricity from yourself. You can simply touch the power supply itself with your hands.
4. Do not touch the board pins.
5. Never use metal tools to clean modules.
6. Assess the situation before starting work. Your computer is under warranty, but you don’t even have work experience? Then give it back under warranty, or ask a knowledgeable friend to help.
