Frozen computer when you turn on one long signal. Computer fries and does not turn on what to do? Decoding sound signals. Computer when turning on beeps and does not turn on

Good day. Today we will talk about why floating computer And what the signals Bios. (But he does it precisely) gives you.

Although it would begin to start this article differently.

The malicious energy turned off the light, and when turned on, the computer became incomprehensible to squeak and refused to work? Brother kicked the system unit, after which the latter makes one exile and does not turn on? Computer sickens so that everything is scary in the district?

You can of course drop the brick on the energy sector and hang your brother for the legs to the ceiling, but how to determine what happened to the computer and what does this most hazing mean?

This material is just devoted to sound signals (or their absence) of the computer, namely their decoding.

Let's start.

BIOS signals - input

Let's understand why the computer beeps and what's what

Signals vary depending on the type of BIOS, which lives in your mat. You can find it in, actually, the BIOS itself (DEL button at the earliest stage of the computer).

How about what other bios you can see on the BIOS. Generally speaking, all modern motherboards have long switched to UEFI, but the essence of this has changed not much.

However, let's be essential.

Award BIOS - Floating Computer - Decryption

The minimum list is approximately like that:

Continuous signal - faulty. Replacement required.
1 short signal - Errors are not detected. Typical behavior of a working computer - the computer is loaded normally.
2 short signals - Multile errors were found. A proposal appears on the monitor screen to enter the CMOS Setup Utility program to correct the situation. Check the reliability of the fastening of the loops in the connectors and.
3 long signals - Keyboard controller error. Restart the computer. You may need to replace the motherboard.
1 long + 1 short signals - problems found with. Check the installation of memory modules. Either replace other memory modules.
- The problem C is the most common malfunction. It is recommended to pull out the board and insert. Also check the connection to the video card.
- Keyboard initialization error. Check the keyboard connection with the connector on the motherboard.
1 long + 9 short signals - Error reading data from permanent memory chip. Overload a computer or reflash the contents of the chip (if this mode is supported).
1 Long Repeating Signal - Incorrect installation of memory modules. Try to pull out and paste them again.
1 short repeating signal - Problems with power supply. Try to remove the dust accumulated in it.

AMI BIOS - Compound Computer - Decryption

What's wrong with what:

1 short signal - errors have not been detected. The computer is ready for work.
2 short signals - Error parity of RAM. Restart the computer. Check the installation of memory modules. It is possible to replace the memory modules.
3 short signals - Error when working in the main memory (first 64 KB). Restart the computer. Check the installation of memory modules in slots. It is possible to replace the memory modules.
4 short signals - defective system timer. It is possible to replace the motherboard.
5 short signals - faulty. It is possible to replace the processor.
6 short signals - The keyboard controller is defective. Check the quality of the connection to the latter with the connector on the motherboard. Try replacing the keyboard. If it does not help, it is possible to replace the motherboard.
7 short signals - faulty motherboard.
8 short signals - Problems with video card.
9 short signals - error checksum of the contents of the BIOS chip. A corresponding message may appear on the monitor screen. It requires either the replacement of the chip, or overwrite its contents (if it is flash memory).
10 short - it is impossible to record in CMOS memory. CMOS or motherboard chip replacement is required.
11 short signals - Faulty external cache memory. Cash memory modules are required.
1 long + 2 short signals
1 long + 3 short signals - Faulty video card. Check the monitor connection with a video card connector. You may need to replace the video card.
1 long + 8 short signals - Problems with video card, or monitor is not connected. Check again the installation of the video message in the expansion slot.

Let us turn to the Phoenix and its signals.

PHOENIX BIOS and AMI BIOS - Frozen Computer - Decryption

Manufacturers of Phonenix BIOS have developed their own system of alternating signals.

1-1-3 Signal - Error writing / reading CMOS data. Replacing the CMOS CMOS or motherboard chip. Also, it may be discharged a battery that feeds the CMOS CMOS chip.
1-1-4 signal - error checksum of the contents of the BIOS microcircuit. Replacing the BIOS chip or flashing (when using Flash -Pamyti).
1-2-1 signal - faulty motherboard. Turn off a computer for a while. If it does not help, replace the motherboard.
1-2-2 Signals - DMA controller initialization error. It is possible to replace the motherboard.
1-2-3 Signals - Error trying to read / write to one of the DMA channels. It is possible to replace the motherboard.

4-4-2 signals - error testing a parallel port. It may be caused by the device using a parallel port for its work.
4-4-3 signals - error when testing the mathematical coprocessor. It is possible to replace the motherboard.

Here is such a big list turned out. View BIOS type "Ah can be in the BIOS itself.

Hello everyone, the problems with the computer often occur. And each user at least once in his life met with problems as a program plan and with problems of computer hardware - some nodes begin to work not correctly or even cease to work. And it would seem that a working computer would not be started at the most necessary moment. I previously wrote in when the computer does not start and beeps - you can define at peaks, which breakdown occurred. But what should I do if the computer does not start and do not be sick? This suggests more serious reasons - when the self-diagnosis system in the BIOS cannot test the main components of the system. In other words, the computer cannot even start and start working. This problem should be divided into three possible causes (errors). First of all, to determine what kind of problem with the computer, you need to open the system block cover to make sure whether there is a system speaker (SPEAKER) and whether it is connected to the motherboard, then carefully examine all the nodes - for an extraneous garbage that can cause failure (closed Runs on the board). If everything is fine then follow the items:

1. The computer does not start and do not cook - inspect the system unit carefully. If we did not find anything, you need to position the system unit so that you can click on the POWER button and at the same time look inside the system unit on the fans installed in it - they will help us determine a possible error. When you press the POWER button, the fans in the system unit are started to rotate, on the motherboard (if there are - LEDs, indicators light up) - such a computer works about the possible oxidation of contacts on a video card or RAM. You can remove them with caution and necessarily when the power cord is disconnected. After extracting, start the computer again - the peaks of the system speaker appeared - already well - clean the contacts and the video card and set them again.

2. If the memory and video card are extracted, and the peaks of the system speaker are not observed - we have only three blocks - the processor, motherboard and power supply. We go along the path of the smallest resistance - we start the computer about 5 minutes. In this case, the fan on the power supply and on the processor rotate, turn off the 220V from the power supply. Then carefully check the temperature of the processor radiator and the southern bridge on the motherboard - see the approximate photo of the motherboard with the designations that is located.

Checked - if the radiator on the cold processor - this suggests that the processor does not work (during operation it heats up), it may have caused a breakdown in order to definitely check the processor will need a suitable motherboard processor - a processor for replacement. We check the southern bridge on the motherboard - if in five minutes the radiator is warm or cold - it can be assumed that the motherboard is workable, and if in 5 minutes of work the south bridge is hot for so much that the touch of the finger can be kept no more than 2-3 seconds because of the high Temperature is talking about the failure of the southern bridge chip. It will be necessary either replacement - a rope to a similar working or replacement of the motherboard.

3. When you press the POWER button, the fans are turned into a trap floor and stop - nothing happens. Indicators, LEDs on the motherboard are glowing. When the power is turned off, it is necessary to check if the fan rotates on the processor cooler - it is necessary to jamble, it lacks proper cooling and the system goes into a safe mode or does not start at all. If it rotates easily, and after the start of the computer ceases to rotate - it may say that the voltage supplied to the main nodes of the motherboard compliance with the requirements of the fee. Accordingly, we conclude - that the power supply unit has started to work incorrectly for the supply of the correct voltage - to make sure that our assumptions must find the power supply unit and connectors, connect and start the computer - with a successful start - the reason is clear - the power supply is either for repair Or replace new. There are such cases when, when you press the POWER button, nothing happens, the fans are not spinning, the LEDs on the motherboard are not lit. This may also indicate the failure of the power supply or the absence of a reliable contact between the power supply and the motherboard or other computer nodes. It is enough to forget to connect a separate power supply of a 12/24 volt processor, or do not apply an additional voltage on the video card - and Malevich on the computer screen after the assembly is provided. I want to notice when disassembly, as well as when assembling a computer, you need to be extremely careful and attentive - because All works are associated with electricity and expensive computer nodes.

Good luck, good luck and good !!!

Each computer user may encounter such a problem when the system unit is encouraged when the computer is turned on and the monitor does not turn on, that is, just a black screen and not any errors.

In this article, we will tell you how to independently try to solve this problem or at least understand what the problem is.

Why the system unit be sicked when the computer is turned on

Many are wondering. Why the system block beeps when the computer is turned on, the signals make up. When you press the power button on the system unit, started, at this point the motherboard holds all connected components. In the event that the check of the components was successful, then you will hear one short signal and the system load will continue. If any component has not been checking, that is, the motherboard did not wait for an answer from this component, then you will hear a combination of sound signals, thanks to which you can understand what the problem is.

If there are some sound signals, it is already good, compared when when the computer is turned on, just the black screen of the monitor, and the coolers are spinning and without signals are not clear because of which the computer does not turn on. Sound signals make up a speaker that is practically on each motherboard. This is a rather small, but very useful device in some cases.

By combinations of sound signals, you can determine the reason for which the system block is fried, for this you need this BIOS signal to decrypt. How to do it we wrote in the article. For example, 1 short and 1 long signal in Award BIOS says that problems are associated with the RAM. And one more example, 1 short and 2 long signals talk about the problem with the video card.

This is how easily you can understand what the system unit signals. Deciphering signals for all BIOS manufacturers we have in this article.

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

First of all, what to do if the computer refuses to turn on and squeaks when you turn on, you need to start with RAM. What you need to do is just carefully pull the bar of the RAM and wipe the contacts with an eraser. If you have several of them, then do it with each bar, as well as change them in places or try to turn on the computer with one bar and at the same time changing it every time. Perhaps what a plank failed or a slot.

If it did not bother, then try to find and put a deliberately working unit to yourself or give your power supply to someone to check.

You can still try to reset the BIOS, for this you need to pull the battery from the motherboard for a few minutes, then install it again.

If any of this did not help you, then most likely the problem with the motherboard, which most often have to replace it with a new one, as the repair will come out tantamount to buying a new one.

Any technique breaks, however, it happens more often with a computer. Many users have come across the situation in which the computer is fried and does not turn on. Immediately questions arise: what happened and how to fix it? Take about it and talk.

What can squeak inside?

The peak of the computer comes from the speaker, and its main purpose is to squeeze. It informs the user about any hardware or system error of the system (most often hardware). After removing the case cover, you can notice a small round black speaker, which is usually fixed on the case itself. It is this speaker that makes a squeak, informing the user about possible software or hardware errors.

Why does the computer beep and not turn on?

If everything is fine with the computer, then when it is turned on, you can hear only one weak squeak, which says that everything is in order with the system. However, such disys in the event of a system malfunction will be much larger. It is good when the characters or words are displayed on the screen for which you can understand the problem and determine the nature of the fault. In the worst case, the monitor flashes and the characteristic squeak is necessarily present. With it, the system is trying to explain to us at what level the failure is.

Procedure

So, you encountered a situation where the computer is fried and does not turn on. What to do in this case? Procedure Next:

Find out the BIOS version of the computer.
Calculate how many pisks make up the speaker.
Find on the Internet (from the phone, for example) a table of faults of your BIOS and verify it, which means a certain number of squeaks.
Eliminate malfunction.

How to find out the version of BIOS?

To determine the fault, you must refine the BIOS version. There are several ways to do it. The easiest is to open the manual for the motherboard, but if it is not, you can simply remove the cover cover and find on the BIOS inscription. There will also be a version.

If you can see any inscriptions on the screen for three to four seconds when you turn on the computer, you can also notice the BIOS version too. You can also go to the settings by clicking the Delete button when the system is loaded.

The most popular versions are the following: Phoenix, Award, AMI, but there are others.

Award signals

So, if the computer is fried by short signals and does not turn on, and the BIOS version is already known to us, then find out the cause of the problem easily. The following signals are characteristic of BIOS Award.

Single short signal	There are no problems in the work
Two short	There are errors when loading. Perhaps the loops are poorly fixed. These are minor errors that can be eliminated even programmatically. It is not worth worrying
Three long signals	In the keyboard controller there are any faults
Two signals of different lengths	Problem with RAM. At a minimum, you can pull the RAM bar, wipe their contact with alcohol and put in place. If the signals did not disappear, then you should try to replace both either one of the planks and try downloading the system again. So you can reveal a faulty RAM module and replace it
One long squeak, two short	Possible breakdown of the graphics adapter. You should turn off the system unit from the outlet, pull out the video card, clean the contacts and connect it back. If the signals remained, the components will have to be repaired or return to the seller warranty
Long, three short	Failure of the video card
One long signal, nine short	The problem of reading ROM.
Short repeating	Problem with PB
Repeating long	Problem with RAM
Repeating signal with variable frequencies (high and low)	Problem with processor
Continuous Pick	Power supply breakage. You can try to clean it from dust, but if the squeak remains, it will have to be repaired or replaced

The table lists the main signals that take place when using motherboards with the Bios Award version.

AMI signals

If it does not turn on with the BIOS AMI version, then the nature of the fault can be judged by the following signals.

1 short
2 Long, 1 short	Defective bp
2 short	Possible problems with RAM bar
3 short	Again a problem with RAM. Her components work incorrectly. At a minimum, you can get the RAM bar again, wipe their contact with alcohol (degreased) and put back. If the slats are somewhat, then you need to try to turn on the computer with the installation at first one plank, and then on the other. This will allow you to identify a faulty module.
4 short	The timer in the system works incorrectly.
5 short	Problem with processor. Itself here is nothing. You need to carry a computer to repair. Perhaps it will be necessary to replace the CPU
6 short	Problem in the controller
7 short signals	Breakdown in motherboard
8 short	Problem with video memory
9 short	Fault in the firmware BIOS
10 short	Unable to read CMOS memory. It is possible to work incorrect
11 short	The problem with the cache memory that is on the maternity board
Long, 2 short	MONO-CGA video system malfunction
Long, 3 short	Malfunction Video System EGA-VGA
Long, 8 short	The monitor connector has deployed either burned
Continuous Pick	Power supply breakage

In some cases there are no sounds at all and when the computer is turned on, the black screen. What to do in this case? It is worth checking the central processor. There is a chance that one contact on the microcircuit was curved. In this case, the replacement of the CPU is shown.

Phoenix signals

Usually, if the beeps come, but the computer does not turn on, the reasons are typical and for motherboards with here only here signals are slightly atypical, so they need to be disassembled using signal codes. For example, the 1-1-2 signal will mean the following: signal - pause - signal - pause - two signals.

	Problem with CMOS memory
	BIOS erroneous checksum. Most likely, you will need to update the firmware of this microcircuit.
	Serious vehicle breakdown. Alone here cannot be done here, you will have to carry it into repair or replace
	Problem with DMA controller
	Violation in the work of RAM
	Another error of RAM. In particular, this code suggests that the first 64 Kb of RAM failed to read. It is necessary to remove the planks gradually and try to enable the computer
	Error preparing for the launch of the motherboard. Most often required fees
	Again the problem in RAM
	The system timer works incorrectly. Most often, the problem is solved in the workshop, however, it may be necessary to replace the board
	Malfunction on I / O ports. External devices can work incorrectly
	Error in determining DMA channels
	Failure of video memory
	Unable to determine the keyboard controller
	The impossibility of determining the bios video card
	The processor operates incorrectly. Perhaps it will be necessary to replace the CPU
	Could not determine the mathematical processor
	Incorrect operation of RAM Planks
	Keyboard controller works incorrectly
	Incorrect work of the first and second timers
	Cannot define a serial port
Long signals do not stop	Maternal, most likely burned
Sound with a transition with high at low frequency	Perhaps on the video card. They need to check and replace
The computer continuously beats and does not turn on	Speaks about the fault of the processor cooler. It is advisable to look inside the system unit and see whether the cooler rotates

Now it is clear that if the computer is turned on and does not turn on, then the problem may hide anywhere from those listed above.

Other BIOS systems

The above error codes for three BIOS systems are shown above, although there are more. In any case, in the instruction manual, you can find these codes specifically for your motherboard. Check it. However, there are ways to determine the problem without resorting to the BIOS.

Definition of malfunction in other ways

If the computer does not turn on, the light flashes and there is a characteristic squeak, it does not mean that a serious breakdown happened to the computer. First of all, you need to try to resort to simple malfunctioning methods:

You need to check whether the external devices are connected to the computer: printer, webcam, mouse, etc.
Disable power and tightened all connectors inside the system unit. It may turn out that some power connector is loosely adjacent to the component. As a result, the system thinks that the video card, for example, is missing and therefore the user sees the black screen when the computer is turned on. What to do in this case? Just press the connector is stronger.
Clear motherboard from dust. In no case cannot do it with a wet and the more wet rag.
Explore your motherboard and search swollen capacitors. If there is such a thing, it must be replaced (digging and solder the same).
Check the fee for the presence of Gary.
You can also try to remove all components and set them again.

In some users who do not have a computer, the reasons remain unknown at all. Even specialists cannot determine the malfunction. In this case, it is necessary to simply change the fee. There is no specific statistics that would allow to understand what kind of module fails most often. Each case is individual, therefore, in the event of a breakdown, you will most likely have to attract a fee for repair.

Will pass?

In exceptionally rare cases, users the problem is solved by itself, and after a certain time of downtime, the computer begins to work normally. This may be if there was insufficient voltage in the network, due to which the power supply could not provide all components of the energy of sufficient power. It happens very rarely, but it is also impossible to exclude this option. However, it is not necessary to hope that the computer will stand and after some time will turn on without problems.

Conclusion

So, we found out why the computer is fried and does not turn on. Unfortunately, if this happens, then it is possible to solve the problem extremely rarely. The motherboard and generally component components are quite complex devices, so if they breakage them, it is advisable to seek professional help. This will save a lot of time, and sometimes money, because in the process of independent repair, users often exacerbate the situation due to their technical illiteracy.

Each computer owner noticed that during the boot, it produces a beep if you have this operation is not disabled. However, not everyone was thinking that this signal means. In fact, the Pisk is not easy to be published. Prior to this signal, all components are tested for performance. If the failures were not detected, a signal is given that signals that everything is in order - one short. However, if there is some kind of problem, with the help of sound signals, the computer will invite the user about the cause of the error. For decryption, many use the instructions that are attached to the "motherboard". However, it is far from everyone, someone lost her, someone bought a computer with hands without it.

Why does a computer beep?

First of all, it is worth explaining why the computer is fried when turned on. The performance analysis is engaged in BIOS - this is a kind of microprogram set recorded in a non-volatile memory chip located on a system board, which are engaged in the verification of the proper operation of all components of the system unit, testing them. The self-test program is called POST - Power-on Self-TestAfter completing it, in case of successful post, the built-in system speaker is published by one short beep, but in case of any failure, various sequences of sound signals are distributed, which allow you to determine the cause of the fault. All signals come from the speaker, which is located in the systemic block itself, is also also called PC SPEAKER or Beeper..

There is a table of values \u200b\u200bfor which you can understand what exactly these signals indicate. Below I will give an example of such a table.

A computer can produce various sounds, long, short, somewhat short or somewhat long in a row, possibly their alternation with pauses. It is worth considering that there are various types of BIOS and depending on the manufacturer and the BIOS version, the sound signals in the height of the tone, duration and various combinations may have some differences. Experienced users with these sounds understand, for what reason the operating system is not loading. The BIOS version depends on the motherboard, so they may have different interface.

While turning on the computer at the very beginning, while the screen shows nothing, the entire equipment is checked, which was connected to the computer. In that situation, when absolutely everything is regular and connected to the motherboard correctly, the operating system boot begins. If Windows or any other system can not download a computer, then there is a problem in connecting or the serviceability of some equipment.

By signals, you can define the source of the problem. After that, try to reconnect this equipment (disconnect - attach back). If it does not help, try replacing damaged equipment and download the operating system again.

After the cause of the problem was set, the user almost always can fix it independently. Disconnect your device from electricity, and then act depending on the cause of the problem.

Computer action plan

What should be a plan of action in that situation when the computer does not load the operating system and squeaks non-standard?

You should restart the computer and calculate the number of squeaks that publishes the speaker in the system unit. It is also worth paying attention to the length of the peaks.
You should learn your version of the BIOS during loading. In most cases, it is displayed at the top of the BIOS settings window.
According to the table for its version of the BIOS, find the designations of these signals. The approximate table will give below.
After that, it remains to try to reconnect the equipment. If this does not give the desired effect, it should be replaced this item. If after the actions performed the operating system booted, then it remains only to purchase the necessary equipment.

POST Card

POST cards are also used to diagnose computer malfunctions. Currently, there are a lot of such cards for various possible situations. They allow you to display POST code and understand the cause of the fault by this code.

Determine the problem without visiting BIOS

The above methods for eliminating malfunctions in the computer will be most appropriate with the help of a competent person. However, any user can try to solve the problem independently. In case the operating system is not loaded, it does not always indicate that the equipment failed. It is possible that the user accidentally burned the wire, and he moved away. As a result, the equipment does not work, and the computer refuses to load the operating system. Therefore, before calling the wizard, you must do the following actions.

Check how your devices are connected. Many are afraid of incomprehensible sound signals and immediately cause masters. However, the problem may be that the key from the keyboard has slightly departed, in this case the computer in most types of BIOS will produce three long signals. It is not worth spending extra money with such a problem.
You must turn off the computer from the network, then check all the motherboard connectors. In particular, pay attention to the video card and for RAM.
Dust can also be the problem of error. Therefore, it is necessary to carefully clear the motherboard and other internal equipment from dust. This procedure should be carried out at least once a week, this will extend the work time of your technology. Cleaning the motherboard should be used with air jet or dry cotton wand.
Examine your motherboard on the traces of Gary. If you feel the characteristic smell, it is worth paying special attention to this item.
Try reconnecting equipment, in some cases, after that, your operating will be able to boot. With too much dust, the equipment may refuse. After reconnect, it can start functioning again.

Sound Signals Table for Ami Bios

1 Long	the test passed without errors.
1 long 2 short	violations in the work of videarters. Two reasons are possible: a) Failure of the checksum VIDEO BIOS ROM, b) error of the circuit that is responsible for the horizontal synchronization of the beam.
1 long 3 short	a) the error of the digital analog converter, b) error when checking the local video memory, c) Error in the monitor definition process.
1 short	DRAM REFRESH FAILURE memory regeneration scheme error. Check the correct installation of memory chips, replace if necessary
2 short	Parity Circuit Failure. error in memory parity. The error was found when checking the first 64K basic memory. Check the correctness of the installation of memory chips, if necessary, replace.
3 short	BASE 64K RAM FAILURE failure of the first 64K basic memory. Check the correctness of the installation of memory chips, if necessary, replace.
4 short	System Timer Failure. faulty system timer. Check the appropriate modules on the motherboard (with their possible replacement). Otherwise, the replacement of the motherboard is required.
5 short	Processor Failure the functioning of the processor is broken. It is possible to reinstall the processor to improve the contact, as well as checking the correctness of the jumper installation for this type of processor.
6 short	Keyboard Controller 8042 / Gate A20 Error error of the A20 Controlline of the Keyboard Controlle. The keyboard controller (8042) contains a switch that allows the processor to work in virtual mode. This message means that the BIOS is not able to switch the processor into the protected mode. You must first check the keyboard and connecting cable. You must also refer to the option "BIOS SETUP" - "Fast Gate A20", experimenting with it. You must reinstall the keyboard controller chip or replace it. Otherwise, it will be necessary to replace the motherboard.
7 short	Virtual Mode Exception Error error excluding a virtual press. Most likely, the performance of the processor is impaired (while the processor generates a special interrupt), and possibly chipset.
8 short	DISPLAY MEMORY READ / WRITE TEST FAILURE display memory read / write test error. The processor cannot refer to the displayed video memory of the graphics card. Check the installation of the board in the connector, reinstall the memory on it. Otherwise, it will be necessary to replace the video card.
9 short	ROM BIOS CHECKSUM FAILURE bIOS microcircuit checksum error. It is necessary to try to reinstall this chip. Otherwise, it is necessary to reflash it or replace the microcircuit.
10 short	CMOS SHUTDOWN REGISTER READ / WRITE ERROR an error is detected when accessing CMOS memory. Call, if possible, "BIOS SETUP" and re-maintain data. Since in most cases this CPAYAN chip is needed to replace the motherboard.
11 short	Cache Error / External Cache Bad faulty external cache memory. Check the correctness of the installation of memory modules. If they are soldered, it is also possible to replace the motherboard.

In custody

A sufficient large number of users faced this problem. With the help of the above-described method of checking equipment without bios in some situations, you can save money on a call to the wizard. However, if you have done all the above operations, and the computer is still not turned on, you should not attempt to restore the performance of the parts yourself. It is better to trust a qualified specialist.

In some cases, the malfunction may appear after contact with the equipment. For example, when replacing the BIOS battery. In this case, you need to go to the BIOS Main Menu, check whether the time is coincided with real, as well as check that the BIOS sees all the equipment. The reason may be in connectors for RAM. In this case, you must try to connect one bar alternately in all slots before successful download, it is possible in the player itself, so you can try to do this operation with another plank.
