Why doesn't the PC turn on? Why doesn't the computer work? The battery charge has run out
A skin care professional may very early on experience problems with starting the computer. You won't ever have problems with your computer when it breaks down, often caused by yourself, and it's even tough and you can just get stuck. In this article, we will look at the most common reasons why the computer does not start, so that you can quickly resolve the problem, and you do not have to call a specialist.
This may be the simplest reason for the computer not turning on, but it is also the most complicated. Let's finish the downtime. If your computer does not turn on, then the most common reason is the lack of supply of food to someone else. It is based on several factors:
- Vimkneno block of life
- Poor cable insertions in the system unit
- The plug was inserted into the cable of the computer.
- Does not use stabilizer or BDZH
- The hemline filter or socket does not work
Another common reason why the computer does not turn on is the incorrect connection of any components on the system unit, which often occurs when people have trouble cleaning the computer on their own, and in which case the core You might inadvertently choke them.
There is a reason - a breakdown of the life block, which often breaks down in computers, because in the middle life blocks there are 3 rocks, after which the smell often goes wrong. If the life block is in operation, then there are two possible breakdowns: either the motherboard has gone wrong, or the contacts have oxidized.
The computer does not turn on, but the fans are running
The computer starts up, but nothing appears? Check all contacts and connections of components on the system unit. Most often, this occurs after self-cleaning the internal parts of the system unit and components. Also, in some cases, it helps to reset the BIOS, for which you need to short-circuit the terminals on the motherboard and restart the computer before starting the reset of the reset BIOS.
The computer does not turn on and is eating
If the computer freezes up, it means that one of the devices or connections is incorrect. Based on the nature of the sounds you hear, or more precisely, the number of long and short squeaks, you can determine where the problem lies. It may be necessary to remove and re-insert this component, clean the contacts or replace it through the outlet.
The computer gets stuck, but it doesn’t get distracted
If the computer boots up, but does not start, for three reasons, let's take a look at them:
- The computer does not load the hard drive on which the operating system is installed
- The system licenser is not specified, or the section that needs to be assigned is entered incorrectly.
- Problems with the operating system
The computer turns on, but there is no image
If the computer turns on, only to see a black screen, then the problem may be that the monitor is not connected correctly. To do this, check the correct connection of the cable that goes to the monitor either from the side of the system unit or from the side of the monitor itself. Then change the settings on your monitor so that the correct connection type is set there: VGA, DVI or HDMI. Also reverse the power cable to the monitor to ensure proper connections.
There is a reason why images can be displayed on the monitor - the video driver. Try putting your computer in Safe Mode and reinstalling the video driver. If this doesn’t help, try connecting the monitor to the integrated video card by removing the discrete one. If the image appears, then the problem is with the video card (try cleaning the contacts and inserting the card into the slot), if there is no image, there may be a problem with the monitor.
The computer freezes and freezes immediately
This situation occurs for two reasons: the cooling cooler has been removed or the power button is jammed. Therefore, check the usefulness of the cooler, since everything is in order with it, then turn on the start button on the motherboard and start the computer with a shorted start terminal (be careful not to run anyone because you don’t have enough knowledge!), as the computer ter started up and did not turn on – repair the button.
The situation is unacceptable, if the computer does not turn on after pressing the Power button, you may end up with some sort of hacker. The reasons for such behavior of the system may be different. It’s not a good idea to panic, because many of them can be killed on their own or turned into fakes.
Reasons and methods
When the computer is turned on, it does not show a sign of life, it does not start, or it does not attempt to access the operating system, however, the reasons for which may be varied.
Let's take a look at the most common problems that make it impossible to freeze your computer:
- electrical problems;
- malfunction of the life block;
- problems with the CMOS battery;
- problems with components;
- Zlomana button zhizhvennya;
- Motherboard malfunction.
Some of these problems can be easily diagnosed and resolved at home, while others can be addressed to our service center through the application form, which is located on the right side of the page. In any case, if you try to put in the wrong, you will be independent.
Problems with 220V
Often, because of their lack of importance, people are faced with elementary problems, rather than panic before the hour. Right now you need to wonder what happened. If the fans do not turn on or the indicators do not light up, it is necessary to check whether there is any activity.
Check that an electrician gets to the PC by following a few simple steps:
- rejoice in the clarity of life in the rosette;
- check the connections of the edge filter to the socket of your robot, for example, by connecting it to a new device;
- Make sure that the power cord is correctly connected to the system unit and socket.
Since the problem could not be resolved by simply checking the PC connection, the problem is likely to be further.
Life block malfunctioning
Problems with PC upgrades often arise from a faulty power supply unit. This problem occurs through voltage surges, which is not uncommon in our systems.
Let's look at the main signs that indicate a malfunction of the life block:
- when pressing the live button, the computer does not respond at all;
- The indicators light up, but nothing starts.
In any case, it is possible to determine whether the life block is to blame for the situation by installing another, obviously reference one. In many cases, when a component goes wrong, you will have to replace the motherboard or subject it to expensive repairs.
Video: What to do without getting stuck
The battery is not working
On the motherboard in the middle of the system unit there is a small CR-2032 battery. This is indicative of maintaining the setup of the basic PC input-output system. The battery life will last for a long time.
However, in some cases, the CR-2032 battery fails after a couple of cycles, and there are various problems with the battery life and switching on. And here you just need to replace it.
Let's take a look at how battery drain occursCMOS:
- the computer does not turn on at all;
- the start is activated after pressing the live button several times;
- anniversary date failure;
- Ensure that the PC is switched on at the hour when the life is supplied;
- rezavantazhennya without asking koristuvach.
In fact, manifestations may vary depending on system configuration and other external factors. You can get the necessary battery replacement at computer, government and other stores.
Drank at the system block
A common cause of problems with starting a computer is its lagging. Failures in this case can manifest themselves in different ways: from a part of the system until it is sufficiently frozen or until it is impossible to start the computer.
The procedure for cleaning the system unit:
- turn on the power supply and unplug all cords from the outlet;
- open the cover of the system unit;
- he saw, for example, drinking penzlik for help;
- clean the contacts of the RAM, video card and other components;
- check the fans for jamming;
- Whenever you need preventive maintenance, replace the thermal paste.
Malfunctions with components
Failure of other PC components may also make it impossible to start the computer. In this situation, it is difficult to independently diagnose problems at home. In some cases, the signals that are sent when the system starts up can help with the identified problem.
Somebody who knows the BIOS software needs it. In addition, a description of the signals that are sent at the hour of heating can be found in the instructions for the motherboard. Most often, the squeak can indicate problems with the RAM or video card.
To resolve the malfunction, you can replace the components with reference ones, but before doing this, it is recommended to try cleaning the contacts using an ordinary school cleaning cloth. In certain situations this method is very useful.
Live button
The reason why the buttons to start the PC are not working may be in the switch itself. As simple as it seems, you may not close your contacts until the end. You can check the problem yourself by closing the corresponding pair of contacts on the motherboard for additional twisting.
Respect! It is recommended to lock your contacts yourself unless you have the necessary knowledge to carry out your activities. Reshti would rather turn to our fakhivts for help.
Motherboard
The malfunction of the motherboard and system board can be detected independently with high accuracy by simply replacing the components with reference ones. In isolated cases, diagnostics can be assisted by signals sent by the BIOS.
Most often, when such a problem occurs, the fans turn on and work, and then the other reaction of the PC to the operator’s actions is displayed. Repairing the motherboard doesn't cost much, since the repair work may outweigh the price of a new part at the store.
Bring back respect. Often faults with the motherboard describe a malfunction, I turn on the computer, but the monitor does not turn on. There may be some confusion between problems with the monitor and the video signal. It is easy to check the operation of the monitor by connecting the signal cable to the system unit and observing the presence of the display screen.
The computer does not connect
The computer may stop working for a number of reasons. Among them you can see the widest ones. Some of them can be installed by the PC owner himself without going to the service center, but we first need to determine the cause of the malfunction.
Let's take a look at the most widespread problems that may prevent your computer from turning on:
- video card defect;
- problems after the processor;
- problems after cleaning;
- disturbances after deep sleep;
- The operation is incorrect after replacing parts.
Video card defect
Problems related to the video card can be easily diagnosed. Right before we turn on the computer, but the monitor doesn’t turn on, the fans start spinning.
When a valid video card is installed, the images will appear. Owners of motherboards with integrated video can use it to verify the usability of the video adapter.
Most video cards fail due to poor cooling, for example, when the system unit or cooler gets too dirty. Therefore, during prevention, it is necessary to pay special attention to the saw blade and the rotation of the fan on the video card.
After replacing the processor
After replacing the processor, computer users often find it difficult to turn off the computer. It's easy to fix the problem.
Let's look at the main steps that need to be taken if the PC stops turning on after replacing the processor:
- check the insanity of the motherboard and the new processor;
- reset BIOS settings;
- contact cleaning;
- Make sure that all components are installed correctly.
Porada . Signals visible through the system speaker can also help in diagnosis.
After cutting the voltage
As a result of a voltage cut, many PC components may go out of tune. As a preventive measure, it is recommended to connect the EOM to the extent of life with vicarious acid stabilizers.
The components that most often go wrong when cutting voltage:
- living block;
- motherboard;
- video cards.
Please be aware that damage can be caused by a number of components and not necessarily from the list provided.
After cleansing
Many homeowners who have decided to first clean the system unit from the saw are faced with the inability to start the PC after folding. In this case, there may be simple reasons or the components may go wrong.
Actions that need to be deleted because the PC does not start after cleaning:
- check cable connections;
- connect to the correct and strong connected sockets of the life block to the motherboard;
- check the installation of RAM and video cards;
- If the cooling system has been removed, it is necessary to ensure that it is installed correctly and that there is sufficient quantity of thermal paste;
- Make sure that other boards and devices (hard drive, drive, etc.) are correctly connected;
- reset the BIOS settings for additional jumpers or remove the battery.
After a deep sleep
Deep sleep mode is used in the first place to reduce energy consumption of laptops and increase battery life. When your PC is corrupted, this method saves all data on your hard drive. After switching to this mode, any system cannot be turned off.
You can start the computer by turning on the main unit and turning it on again. Whose operating system may fail to start. Come quickly and update the system.
After replacing the motherboard
Most of the PC owners are trying to replace the motherboard because the old one has failed. In this case, it is important to check the combination of the new board with other components, as well as install it correctly. However, in any case, problems may arise.
Let's look at the main steps when the computer does not start after replacing the motherboard:
- reverse the connections of the life block and install the additional cards;
- Immediately turn off the hard drive and other external devices without any need to start;
- check that the OZP is installed correctly, clean the contacts on the modules;
- try to launch the board without installed OCP and video card and check the visibility of signals through the speaker;
- successively replace the life unit, RAM, video card, processor with a smart one.
If the PC still fails to start after all these steps, it is recommended to go to the service to check the functionality of the motherboard.
After the update
During the installation of any updates, the functionality of the operating system may be disrupted and as a result the PC will stop starting. To ensure the best results, you will need to upgrade the system quickly.
Launching the system update process inWindows 7:
After this, the system will try to resolve startup problems on its own. If the problem goes away, you can try reinstalling Windows.
When replacing RAM
Problems rarely arise after replacing RAM. You will need to re-convert once you have selected the correct modules.
Let's take a look at the steps that need to be taken out if the PC stops starting after replacing the memory:
- check that the module is installed correctly;
- try to launch a system that is similar to Vikorist with just one module;
- clean contacts;
- Vikonati test launch of the system from the informational help module.
The computer gets stuck, but
In some cases, the computer is warmed up, the fans start, but the operating system is not activated or the image on the screen is displayed. There were many reasons for this behavior by EOM.
Don't get carried away
If your computer is tired and not addicted to Windows, you need to look for the problem in it yourself. This behavior occurs when the program is recently updated, incorrectly installed, or simply due to a malfunction in the robot.
You can try to fix the problem with your operating system in the following ways:
- start the computer in safe mode and try to go to one of the advanced update points;
- learn how to update the OS;
- scan for the virus using special anti-virus disks;
- reinstall Windows.
Warto note that in some cases, the inability to start the operating system may be due to a hardware malfunction. You can also try specialized utilities for testing the HDD and OZP, or go to the service center.
No image
In some cases, the computer will start, but there will be no image. When this happens, all the fans turn on, almost like the hard drive is running, and sometimes Windows starts, which is accompanied by a characteristic sound. This problem is of a morbid nature.
- check the correct cords;
- connect to the robot monitor by connecting it to the system unit;
- clean the video card contacts and check the cooler operation;
- Try using another external or integrated video adapter.
The problem is that the computer does not connect or does not start the operating system. There are plenty of them you can try to solve on your own, speeding up the rewards of this article. Since nothing helps, since the diagnostic process seems complicated for you, you will have to contact our accountants for help, having abandoned the application. Don’t waste an hour if you don’t have enough to answer, don’t disassemble the computer, you can render your job impossible, and our fakhivs will quickly help you.
Hello, dear readers!
We continue our topic of repairing computer equipment. Today’s article will be devoted to what to do if your computer (or rather the system unit) does not turn on. Or it happens like this - the system unit turns on, the fans make noise (the coolers are running) like before, but the monitor is quiet and dark... Just a black screen and the speaker does not beep.
So, in our last article (), we looked at problems with the Windows 7 and Windows 10 operating systems in the software plan, and also identified possible upcoming problems that involve more technical issues related to the peripherals and hardware. And they didn’t realize the roses at the boundaries of the past state.
Subscribe to the blog to know more about computer nutrition. We would like to help you with your problem. We have great respect for the fact that symptoms and causes may be different. If you have a special problem, write lower in the comments.
So, the most common reasons that converge are:
Well, today we are talking about problems with starting the computer. And I will gladly recognize how to solve a whole series of other problems.
The situation is great, because there are really a lot of reasons, but the symptoms are the same, I have already overestimated them.
I’ll try to combine today’s causes and problems into one solution. Because we have a reason for this, we will work in different ways...
We have uncurved the system unit! This is a brave decision, why don’t we stick to today’s main points - you know when it’s necessary, and when it’s not. And learn how to do it yourself.
« But we can reveal it ourselves - but it’s not safe!"- Vigukne oberezhny chitach.
I hasten to reassure our readers.
Of course, since the computer is still under warranty, it is impossible to open it!
And in the event of a fallout, it is possible. Why, I’ll tell you right away. At the beginning of the development of modern computers (approximately the beginning of the 80s of the 20th century), most companies produced their personal computers (to put it in one word) - “disposable”. The most prominent representative who has kept this trend alive is the corporation Apple. If the computer gets old, it is difficult to update its hardware. It's easier to buy a new one. And the axis company IBM long ago propounded a different principle. The body has a significant filling made from various types of winemakers. And the student can choose his own computer as a constructor - or the details would be crazy. And if there is a breakdown, “parts” can be thrown out and put back in reference. Or I’ll be more productive .
This principle is called The principle of closed architecture" Nowadays, IBM PC system units have rapidly dropped off the Apple and other computer markets. And we communicate with you through Windows, not MacOS. The “designer” trend is as relevant for us as before.
Beyond laptops! Laptops (and all-in-one PCs) are a separate class, their hardware depends on the manufacturer and the specific model. For them this principle does not apply.
Solving the problem:
When the computer transforms into a “patient”.
Get ready before the “operation”. From now on, you need to connect everything - keyboard, mouse, monitor, live device, webcam - everything is turned on, and the “patient” is placed on the operating table. To carry out the “operation” we initially need: a lightening garnet, a cross twist, a small penzlik, alcoholic servings, a saw and a saw sucker.
Place the system unit with the top cover facing you, find two metal bolts and screw them in.
From the sides of the screwed bolts, we pull the cover until it is pulled out, and the axle is approximately what we need:
Well, Rostin showed that death came after Rostin... Hm.... What am I talking about?
Let's begin to sort out the problems in order.
Problem 1: The computer does not start. The system unit does not see a short squeak at startup. Black screen; the fan and the system unit are working... But the computer does not turn on the first time, only after rebooting (Hmm... what are the reasons?)
And the reasons are as follows:
- Statistical electrical engineering;
- Having turned off CMOS or popularly - BIOS;
- Does not require ownership, connected through slots to the motherboard. They include video cards, edge adapters, modems, RAM, recording devices, transfer devices, information storage devices, and the USB card reader connector itself.
Faulty life block
The computer's motherboard is faulty (an important, but rare failure)
Unfazed by such a blatant list, you run into it on your own, but it’s not as easy as you might have found it.
Read carefully and do not rush everything - and you will succeed!
Let's get ready. All items need to be completely drained. For neglect of this, the motherboard could go wrong, the author of the article is not responsible for this type of evidence!
Take a careful look at the outlets to which you have connected all peripheral devices; We carefully look at the differences on the front panel.
Quite often the reason to complain about them is that the plug in the headphones was broken - having lost the middle; The USB socket was broken with a flash drive, the contacts were bent, there were foreign objects in the middle, wood, saws. We look at all the sockets - keyboard, edge card, monitor, card reader. Damaged, bent, closed contacts are not to blame
This is what the reference roses look like:
In case of damaged roses, use a thin tip to open the contacts so that the stench does not stick together; The faulty rose is sealed with tape, electrical tape and is no longer corroded.
As everything is ready, let’s start looking at the motherboard.
Let's continue our look...
Pershe, scho mi bachimo, chain. In my photo the saw is no longer there, but in yours it is. Pil – static electrics source. Piling up in the middle, it settles on the jet-conducting elements and accumulates an electric charge. The life blocks show their presence, go to the defense and the main reason is that the computer is working, but does not start (does not start). Penzlik throws off the saw. With great demand, the saw cleaner is actively stagnating, collecting saws from the fans. The thin ball of the saw is carefully rubbed with an alcohol scraper as far as you can reach.
Use a vacuum cleaner to clean it carefully, preferably turn it on in sight, and in any case, clean it on the payment station. It is necessary to use the saw again. And often, it’s enough to just lower yourself and blow hard with your mouth, so as not to harm anything! Also, be careful not to scratch your servettes and not to wipe them every time. Only wiping the ring in the middle of the body is allowed.
It is necessary to act carefully, fanaticism and strength should not be stagnated at all times.
We pull the round battery out of the socket with a thin twist.
Let's check the voltage.
If it is below, below is written on the battery - we replace the battery. By removing the battery, we can save the remaining cost of life, and immediately throw in the steps of setting up the BIOS to factory settings. Replacing the battery will also cause problems starting the system unit - and another possible problem will be solved.
Before we speak! Without checking the battery for charge, you can simply replace it with the same one. Just take it and buy one from the nearest computer store in your area. A low battery is one of the most common reasons why a computer won't start. There is simply no voltage! On computers less than 3 years old, the problem rarely occurs. Rest assured, the batteries last for 3-5 years, as far as I can tell. If you have the same problem, write a comment below.
You can continue to resolve the problem by starting the computer.
All cables from the motherboard are visible - hard drive(s), life block:
This is how the connectors to the life block appear:
1st axis here:
Hard disk(s); Here's what you'll see (the same slot on the DVD drive):
If a significant video card is installed, it will work. We twist the screw, pull out the card, and look around. We take the saw, the video card slot is wiped with a straight saw. We look around the video card fan - we are cleaning up everything from under it; Let's check that it's not true. Everything is so good, but nothing is readable.
In advance: Please do not clean the buttons on the system unit and on external USB ports; Removing them takes less than an hour, and installing them on site!
If there are other devices in the seat slots, we pull them together and repeat the action.
We pull together the RAM strips:
We press on the latch and pull the strips out of the slot. I drank through it carefully and carefully cleaned it up with a thin servlet.
The pilosos and serverets are stagnated with diligence- Until all slots.
Once you have purchased the motherboard, you can definitely remove any excess waste from it.
Hooray! The system unit and motherboard are clean! Because I drank wine, we solved the problem. Even though they have not yet done a general tidying up, they have carried out preventative measures.
Problem 2: The fan is working at full speed (the cooler is humming or making noise), but the computer does not start or freezes
The time has come to look at the biggest problem. So far, all organs have been removed and the patient is “under anesthesia” on the operating table. It's time!
Let's talk about the CPU fan. Who remembers the movie "Terminator 2"? Cool story!
Hooray! We can now get to the processor))
Get ready! On different types of motherboards, the mounting of the processor radiator fan varies! Like a butt - mounted on an Intel processor. They stink, they stink, they stink for AMD. It’s easy to find out, but it’s more important to install it without harming it. Be respectful, be careful and don’t rush.
Do we currently have a radiator with a fan? It is necessary to work when replacing them, to clean the radiator from the saw and to put fresh thermal paste on the processor. Everybody come in intended to steal yourCPUdue to overheating.
Symptoms of overheating will also occur:
Problem 3: The computer freezes on its own during playtime (which is independent)
Other problems can be added here. And to yourself:
Raptov's understanding of the computer after becoming more and more familiar with Windows;
The computer does not turn on, while the cooler is running, the screen is black and the speaker does not beep (and thus becomes sharp);
The computer fan is humming. The cooler makes so much noise to the system unit that it is impossible to operate.
Get ready! These symptoms can often be caused by a malfunction of the video card, including the installation of a fan.
Sometimes, if the settings are adjusted when the processor overheats, the system unit experiences prolonged squeaks (more often during baking hours) and freezes after a constant hour, or continues for a long time immediately after startup.
On older models, the connections between the processor and the cooler are tight. Sometimes the noise is caused by wear and tear on the fan bearings. In such cases, the radiator with fan must be changed to be more efficient and less noisy. Before you continue the repair, write down the name of the wet motherboard, because most of the leaks are on the board itself (photo below) and in the store select the required cooler for it. It always comes complete with a radiator and the price is low. At the same time, buy thermal paste.
We turn the arrow (which is embossed) straight through all the latches. We lift the clamp along the line, and then the radiator is also lifted. Don't forget to keep the fan running.
We remove excess old thermal paste from the processor and cooler
Apply the new one carefully, the amount of mouth needed is small. As shown in the image below. Then just gently smear it with your finger (don’t overdo it...).
Carefully place the radiator in place.
Respect! Insert the clamps into the board very carefully, without tightening the force until there is a characteristic click. Once you have finished drinking until the stench begins to properly push down, you will otherwise break it. After this, do not forget to turn the lock on the seat.
As long as the radiator is worth it, doesn’t leak or break, that’s all! Life has been made easier for the processor.
Problem 4: The monitor does not turn on when the computer starts (does not show an image, but the light is on and the computer is running)
This is one of the symptoms of a video card. There is a video card - it is installed (it looks like this)
…і not invoked 🙂 (discrete), there...
...inserted into the motherboard slot.
Ours has two cards. If you can stand for two hours at a time, it’s easy to misunderstand that it’s not working. Please note that when the “discrete” device has ceased to function, the monitor is connected to it, it is tightly connected to the slots, and the cord from the monitor is connected to the outlet. Otherwise, you need to earn money by chance. As a rule, the images on one of the cards will appear without fail.
In a number of cases, video cards seem to fail if their fan is damaged or “erased.” You can also try changing it from your local store. The faulty video card is replaced. If you no longer have a built-in video card on your computer, you will need to buy a new one - a discrete one; They are carefully selected for the motherboard, depending on your preferences.
If the problem already arises in replacing computer parts, but you don’t have enough information, then the best thing to do is to go to the service center, where they can advise you without cost, and also recommend that you upgrade and upgrade your computer or laptop.
Marking of motherboard:
Problem 6: RAM
Failure of modules or RAM modules can also prevent the computer from starting, starting the computer, or freezing. It is important that the PC starts without the RAM sticks, but without the RAM sticks, which means there is a bad contact due to incorrect installation, or one of the sticks has gone wrong. We are selecting a new level again - due to the complexity of your motherboard, and at the same price.
Installing RAM will greatly improve the performance of your computer!
Problem 7: Life Block
The remaining inconsistency, as we see today, is plaguing the life block.
Coming out of harmony with the life block is a frequent occurrence. All the symptoms of an over-inflamed body can be diagnosed in the same way before the life block, if it goes well. It also has a fan, which is noisy and loud. Electronic components that come out of order over time.
If you have gone through all the steps, installed everything in place, but the computer still does not start - we check the life block. I pay this by connecting the reference block to the motherboard (to other devices is still not necessary). I’m not removing the old block yet. Once the computer has started successfully, I replace it with a new unit, of the same strength and with the same number of connectors (their number varies, but it is necessary to repair them).
The life block is easy to change. After you have completely connected all the sockets to all devices, unscrew the pin on the body:
...we install a new block, fix it with screws and that’s it.
Get ready! If you plan to install heavier hardware on the board - (for example, an additional video card or additional hard drives), the strength of the new block is at the expense of that on the old block. It's better, it's better!
After we have finished everything, we carefully place all the devices in place of the processor cooler, a new life block; then RAM, then video card; We connect the life block to the motherboard. We put all other devices in the slot. We connect the monitor.
Don't forget to install the battery on the seat.
After everything has been verified, let’s turn to life. The computer is guilty of starting up when it sees a short squeak. There is no noise. A picture appeared on the monitor. Hooray!
We remove it, put the cover on the system unit, and fix it with screws.
So, wait, what is this detail?But not like a different TV!:):):):):)
All the troops are coming to their place. That’s it, our “patient” is alive and well.
In this article, I have consistently tried to familiarize you with the process of self-diagnosis and elimination of malfunctions - from the beginning to the end, but you can start, for example, directly from the life block, which is the one on the right in the new one. Here on the right is a specific vipadka. The principle is “Don’t bother working with cars”, which is what needs to be done. 🙂
Read this article for you yourself. I can't get enough of repairing motherboards and hard drives from her. That’s why the “illness” topic is so great.
If you need specific food, write in the comments, we will help you.
Axis and everything today. To all readers - a healthier and better mood. Boo!
In fact, if the computer doesn’t turn on, you can figure out the reason on your own, without missing a beat. There are not many reasons for this situation, and it means that everything went well, you can literally do it for 5 dollars. I want to know about this today, how to perform independent computer diagnostics.
To avoid overwhelming your head with so much information, quickly navigate through the article and go to the section with your symptoms.
The computer does not turn on and is eating
Let me guess, sing-song, have you opened your computer to clean it or change the components? There may be problems if the computer doesn’t read anything, and it starts making beeps when it’s turned on. As if it were not there, the speaker gives a signal that something is connected incorrectly or has gone wrong.
Your PC has different signals, which may include: short/long beeps, 3-5 beeps, or continuous beeps. The skin uses these signals to talk about a specific problem, prote, the skin bios has its own signals. To begin with, you need to know what BIOS version you have. The easiest way is to remove the cover of your PC and look at , look for the chip there that says BIOS, and under it there will be a version (AWARD, Phoenix, AMI, Intel, UEFI).

In my practice, it is most common to squeak through RAM. Correction is simple: remove the RAM, wipe the contacts and push firmly into place until it clicks into place. In terms of other sounds, there is information behind the skin of these information on the Internet that is easy to find. I don’t really want to describe it, the article is so cumbersome.
The computer does not turn on at all times
When you press a button, the computer does not turn on. There are no emotions, sounds, squeaks, indicators do not light up - turn the food over first. Once you have changed the socket, firmly connected the power cable and, as before, quietly, remove the lid of the PC and turn it off. To spin means to scroll the page. Below, since, as before, nothing happened, let’s check it for feasibility.
How to check the life block
- Unscrew the life block from the computer case and remove all the arrows. Remove the life block from the computer.
- Take a violin and break it until you get a letter U.
- Take the thickest wire harness with the largest opening (the one you connected to the motherboard) and insert a clip to close blackі greenery drit:
- Connect the power cable to the power supply and plug it into the outlet. Important! Do not touch the power supply in your hands and turn over so that all the arrows are connected to the mat. pay.
Now it’s one in two: the block of life is either silent or active, or there will be silence. If the power supply is requested for additional black and green power supply, then the problem is in the motherboard, if it is quiet, then you need to buy a new power supply.
Self-repair of power supply: It would be possible to write about those how to renew the block of life, but, I’ll say more than that, as if you couldn’t do it, you wouldn’t have read it. In addition, often after improper repair of the living unit, other components burn out. I strongly recommend buying a new one (not expensive) and saving your computer and your time.
The computer does not turn on, but the fans of the system unit are running
It is not acceptable to have a situation in which practically everything is not understood. Under this symptom, there may be a lot of breakdowns that you will have to sort through to understand what has happened.
- Faulty power supply. Possibly, it gives tension, but it’s not enough. To start, open it up, turn it over so that there are no traces of burnt parts on the capacitor board, and turn the capacitors over so that they don’t smell like in this photo:
As you have shown, above all else, the problem lies in itself. The power supply is working, but not at full strength and the computer is not bothered. To re-convert the rest, take a working life block from someone and place it on your own to re-convert.
- Video card failure. Your computer is working harder again. Where is it the same as before the breakdown? So, connect the speakers to the computer, turn it on and check the system settings (the sound of the OS is installed). As it happens, you see that the PC is working, but there is simply no image, which means that the video card is faulty.
- Zletiv Bios. I guess I have the same idea. To try to fix it, turn on the computer, remove the cover, remove the battery (about 5 kopecks in size, similar to the battery in a car) and check for 20 coins. Then insert them in place and turn on the computer. If it helps, I exited the BIOS and I recommend checking to see if there is an update available for your motherboard. pay.
- The problem is with the components. Almost always in such situations the speaker informs you that you are on the computer, but not turned off, that you don’t have anything or it’s faulty. Connect all the components one by one until you find out what the problem is.
Exit from video card. If you have an integrated one and an external one, try to remove the external one and connect the monitor directly to the motherboard. If that doesn’t help, remove the RAM, then try inserting it into another slot. Find the HDD on the right side and the image will appear.
- We check the motherboard. Wait, there's a big chip on the board (like a box of sourdoughs), is it possible to install an aluminum radiator?
This is a chipset that you can check. Open the computer and touch the chipset 3-5 times. It will become even hotter, which means that the place will burn. I don’t recommend soldering it, because the computer won’t work for a long time and in a short hour the breakdown will happen again.
You might also be amazed by the video, it’s entirely possible that I’ve lost everything, but still haven’t gotten around to it at all:
Although nothing helped, it’s more likely that your motherboard burned out. As I said above, it’s not a good idea to solder, because a breakdown is just around the corner.
The computer does not start up the first time
Well, after all, you have a life block or on the motherboard, there are blown capacitors (the example of the picture is more amazing), that’s how it turns out. As far as I can tell, you will need to turn on the computer and re-solder it or take the PC to a service center. So far, your computer will not turn on the first time, and then the entire motherboard may burn out!
Reason #2 – bad contact. Open the computer, log out everything you download and reconnect everything in place, reconnecting so that everything is connected well. It is also important to wipe the contacts with alcohol, then wipe them dry and put them back in.
That's all, I hope, I have helped you, and you will resolve your problem without going to the service center.
The computer may not turn on due to incorrect connections or faulty cables, faulty software, incorrectly folded or damaged internal parts. These problems can no longer be solved. Before you repair the device, try this out.
If the computer stops running after you take it out, turn it over so that all parts are properly installed, connected, and properly locked in place. Only then move on to the next steps.
1. The computer does not react at all to power-up tests and freezes immediately
Check to see if the socket is working. Check the correct connection and integrity of the cables. To connect to the power supply, use a rubber band and turn the button over. Log in to your computer. Perhaps there is an additional life switch on the back of the system unit - turn it over.
If you have a laptop, put it on charge and charge at least 30 minutes, then try to turn on the device again. If the charging indicator does not light up on the power adapter or laptop, and the device does not turn on, replace the charging device with a valid one.
On many motherboards there is a significant battery, which is always part of the computer's setup and does not go away after it's turned off again. If you are not afraid of voiding the warranty, remove the device from the electrical circuit and open the case. Then carefully try to remove the battery and install it in place. Please delete all the settings that may be enough to make your computer cool.
If reinstalling won't help, it's possible your battery just died. This can also affect the inclusion. If you haven’t replaced the battery of the old one, you can buy a new one, install it in place of the old one and check the computer.
Be careful, the battery may be damaged on some devices. In this case, there is no way to replace or reinsert it.
2. When you wake up, you only see a black screen
It is acceptable that after starting up your computer is working, the lights are glowing, the coolers are making noise, but the screen does not react at all.
If you are using the wrong monitor and its indicator does not light up, turn the cable over and make sure the monitor is connected correctly. If possible, replace the cord. If you can't help, take the monitor to the service center.
If the monitor indicator is working or you have a laptop whose screen turns black, then you can see that everything is wrong with the hardware of the computer. In this situation it would be better to turn into a fiancé.
If you have a computer, turn off all devices near the monitor and try turning it off again.
In some cases, it also helps to reinstall or replace the battery on the motherboard (the first step).
3. If the computer is closed, rather than using Windows
Since Windows never begins to become attractive, or it will continue to be attractive for a long time, hurry up.
4. If your computer is turned off or not running macOS
Try starting your Mac in Safe Mode. To do this, after pressing, press and hold the Shift key for a few seconds. If you have a MacBook, connect it to the power supply first.
Once the computer is started in this mode, the system can automatically correct problems that were caused by startup. Restart your devices without pressing hard on the keys and make sure macOS starts up again. If all else fails, try updating your operating system.
5. Nothing helped
If they didn’t help you, you can contact the service center for help or try to return the computer to the store for a guarantee.
