DIY system unit repair

Computers are constantly working, the system and programs are updated. Due to our actions, or because of errors in programs, or maybe from the consequences of viruses, the system may start to fail. Of course, almost any problem can be solved with someone's help or on our own.

Many people want to do their own computer repairs, but there are 5 things that you better not do if you do not have experience, or at least 100% accurate instructions on how to do it right. Instead of solving the problem that has arisen, it may turn out to be even worse. There is a lot of different information on the Internet, both in the form of articles and step-by-step video instructions. But a computer is a complex device, so some things should be done only with full confidence in the correctness of the actions.

1. Editing the system registry... The Windows Registry is a complex hierarchical database of information. It stores all the settings and parameters of the operating system, installed programs and equipment. Stable and correct operation of the system directly depends on the registry. Corrupted or incorrect data in the registry can lead to a system crash. If Windows stops loading or starts to work worse after manipulating the registry, use checkpoint recovery.
2. Removing files from system folders... In general, Windows warns that you are entering system folders, and by default their contents are not displayed (in the case of using the standard Explorer). But sometimes you need to delete or change files to solve a specific problem. But without special knowledge or correct and detailed instructions, it is better not to go there. There is a great risk of getting a broken system, and restore points may not help.
3. Do not dig into the system unit... I'm not talking about the fact that in no case open the system unit. You just need to clean it from dust, add a memory bar or replace the video card. But some people try to replace the motherboard or the cooling system on the central processor or video card, and then they cry that nothing works. Computer components are very fragile and capricious things that are afraid of static stress and awkward movements. Step to the left, step to the right and at the exit we have a non-working computer, or even smoke. If the computer does not turn on, you can try what you are sure of, and leave the rest to the specialists.
4. Don't play with BIOS... In addition to the operating system, the computer has another "mini-operating system" that controls the computer before Windows boots. The BIOS controls the CPU, fans, hard drives, and other devices, and stores the parameters of their operating modes. Changing the BIOS settings incorrectly can lead to a complete inoperability of the system, or to minor problems such as slow operation or inaccessibility of some devices. Do you need it?
5. Command line manipulation... As many people know, the command line is a powerful tool for controlling the behavior of the operating system and other programs, but only with skillful use. If you run the command line and start executing commands, especially those related to changing the file system or other data, you must be sure that you are doing everything right. Otherwise, you may find yourself face to face with a more serious problem than it was before. And this is really bad.

Do not repair your computer yourself if you do not understand or have precise instructions.It is better to ask a friend or a computer technician for help for little money, or at least use reliable sources of information! For novice users, I advise you to watch a video on the program for optimizing computer performance and solving problems.

Now almost every home has a personal computer. Each user can do a computer repair himself, with his own hands.

The technique is quite reliable, especially in capable hands. Also, reliability, or better to say, the lifespan, will be added to it by a surge protector or UPS (uninterruptible power supply), because it is no secret to anyone that the voltage in the electrical network periodically jumps.

This phenomenon is associated with various factors, breakdowns in the network itself or a transformer box, the inclusion of three kettles, two hair dryers and a pair of heaters in one outlet, a strong wind plays with wires, well, and so on. And some elements of the computer are afraid not only of a jump in the network, but simply of the static electricity of the human skin. So, before we climb inside the computer, we will not grab our heads, but put our hands on the battery, after which we will take up the repair of the computer with our own hands, so to speak, closely.

So, the first problem - the computer does not turn on. The first thing we do, usually, we look to see if it is included in the network, after which we press the button ten times again. If it doesn't help, panic begins. You should not panic, check if there is electricity in the house. If so, there may be several faults. The most common problem is a faulty power supply.

By itself, it looks like a box with a fan inside. You can find out by connecting the computer with a different power supply. But few have one. You can also, after disconnecting the computer from the network, disconnect the power supply from the motherboard (wide connector, more often white, do not forget about the second smaller connector). When all the wires are disconnected, now we reconnect the computer to the network. On the wide connector of the power supply, we need to close two contacts: green and black (any black). If it does not start, we go to the store for a new one.

Wide power supply connector

Very rarely, the reason may lie in the breakdown of the power button. This is also easily verified. On the motherboard we find two pins where PWD SW is written next to them.

Power plugs on the motherboard

The easiest way to do this is to follow the wire from the button. We remove the button connection connector, and close them with a screwdriver. If it does not start, then it’s not her problem. Once again, this is an extremely rare occurrence and most likely the reason is in the power supply. After all, even a faulty motherboard will turn on, even for a second, but the cooling fans will work.

By the way, it is the cooling fans that are the main culprit for the huge amount of dust inside the computer case. Any electronics are afraid of dust. Especially difficult. So we periodically clean and blow out the computer. You can do this with a can of compressed air, a vacuum cleaner, a watercolor brush will help us a lot in this matter, I confess, I like the fox more.

The second problem is that it turns on and, immediately, turns off. I came across this several times in my practice. Either the motherboard or the processor is defective. Let's go in order. There are many voltage-rectifying capacitors on the motherboard. Due to overheating, they, over time, lose their capacity and fail. Therefore, make sure that the computer does not overheat. But don't rush to throw out the motherboard. The motherboard gradually fails from overheating. This is accompanied by the freezing of the computer, very often, with the same "Blue Screen of Death". So, the "mother" will not be covered right away, but will still shake your nerves for several months before that.

Processor and applying thermal paste to it

If it happened spontaneously.

Most likely, the processor is to blame, or rather, its insufficient cooling. And there is even a possibility that he is intact. What are we doing? Do not forget to put your hands on the battery. Disconnect the computer from the network. Remove the housing cover. We need to get to the processor. It is located under the largest heatsink, which, in turn, is located under the largest fan (in general, it is correct to call such a fan in a computer a "cooler") on the motherboard. You can see that there is a wire coming from the cooler, or rather three wires usually wound. Disconnect them. Now we are going to remove the cooler with the radiator. We are in no hurry to grab the screwdriver. On almost all modern motherboards, modern radiators are fastened with clips and removed / installed by hand.

You may have to tinker. Above all, do not apply force with your entire arm or body weight. Only gently and only with your fingers. Having removed this "construction", we see a small metal (on modern computers) box. The cover is opened by lifting the metal tab. We opened the lid and very carefully took out the processor. You will not see that it burned down, unless you throw it into the fire. First, look at the place where the processor was installed. There are many, many little paws. Look closely to see if one or more are bent. If it is bent, then holding your breath, you can try to straighten it with a needle, but I do not advise. We will postpone this procedure as a last resort. Next, we need thermal paste. You can purchase it at a computer store. Thermal paste helps transfer heat away from the processor to the heatsink. After all, if there is even the slightest angle between the planes of their surfaces, then there is also a gap. Thermal paste, as you might guess, eliminates this gap.

Extruding thermal paste onto the processor

You need to apply it to the processor, having previously cleaned it off from the old, dried one. Having put the processor in its rightful place, we install the heatsink with the cooler in place. We connect the cooler. We turn on the computer. If everything is the same, then most likely the processor will have to be replaced. We also apply thermal paste to the new processor.

Third case. The computer turns on and beeps without booting further or even without turning on the monitor. And we are all used to one short squeak every time we turn it on. This signals that the initial test is complete and that all components are in good working order. But when he beeps something like a melody, this is already a signal about a malfunction of some component. The set of these melodies is quite decent, the meanings of each melody depend on the firm and model of your BIOS. You can find out by finding the BIOS chip on the motherboard.

BIOS chip from AMIBIOS

If AMI is written on it, then we look at the table below, if Award, then we look at the second table even lower, and if not both, we go to a friend, neighbor, turn on the computer and go to Google: my.housecope.com/wp -content / uploads / ext / 1717. Search by the name of your BOIS.

This phenomenon is mentioned earlier in this article. May be caused by overheating of the motherboard. But not only this can become its cause. Overheating of the video card also results in a blue screen. Monitor the condition of the video adapter cooler. And, as has already been said, you should not play resource-intensive games in the summer heat. But this phenomenon itself is associated with a fatal error in the operating system kernel. When any program or driver running in the kernel tries to execute an invalid command, this error occurs. The only way is to reboot.

Fifth case. The computer hums like a tractor. This is due to the cooling system, namely the coolers (fans). Over time, the plastic gasket in the cooler bearing wears out, it gets clogged with dust. This leads to its vibration and buzz. The easiest way to fix this problem is to identify which cooler is buzzing and replace it with a new one. In general, it is very easy to identify this. The cooler in the power supply almost never buzzes.The cooler on the video card and the cooler on the processor can buzz. Let me tell you a little secret. There are coolers that can be disassembled, and there are that cannot. If the decision is made to eliminate the hum, then the old cooler is no longer a pity. We remove it from the radiator, for this we will have to twist it with a screwdriver. We need a small cross. So, here it lies in front of us on the table.

The place where the wires come out is usually covered with adhesive tape. We remove this film and watch. If you can disassemble it, disassemble it. The cover can be removed with a small flat screwdriver. Next, freely remove the axle with petals from the cooler case. You will probably see an off-white piece of plastic - this is the remainder of the gasket. It is necessary to clean the axle and where it is inserted with a match, cotton wool, cologne. Making a new gasket is not difficult. Take a clerical knife, find an unnecessary helium pen refill and carefully cut off a thin ring. It will be the new strip. As a lubricant - even sunflower oil. We put the axis in place, fix this case with a plug. And voila, the cooler runs as quietly as new.

Sixth case. The computer turns on, the system boots (but very slowly). Everything seems to work, but, again, the "My Documents" folder opens for almost a minute. Etc. A typical case of a hard drive failure. The hard drive is very afraid of dust. Try to blow it well. Do not try to disassemble. It must be sealed. If it does not help, apparently, you will have to buy a new one. If such a situation arises, it is better not to hesitate with the purchase. At any moment, he can finally give up. The result is irreparable loss of your data. Here I would like to say that a backup copy of your data is an insurance not to lose it. Buy yourself an external hard drive that connects to your computer via USB.

Photos and other personal files that are dear to you are best stored on an optical disc. When stored properly, that is, in a box on a shelf, this is the most reliable way. Here are some examples from my personal practice. I had an eight gigabyte USB flash card. There were a lot of documents, all kinds of programs and other small things. A friend asked to throw off the antivirus. It happens that the USB port does not supply the correct voltage. The faulty motherboard is to blame. It was in such a USB port that my flash drive was destined to please. It just burned out instantly. Nobody will return your data to you, but the program or reinstalling the operating system is a matter of fifteen minutes maximum.

I would like to give you some general tips for using your personal computer.

Disfigured Lyser Disc

And at best, to the terribly tedious process of disassembling the drive, cleaning it from disc debris, and reassembling it. This is a simple procedure, but not everyone can handle it. Do-it-yourself computer repair, after all, requires certain knowledge and skills.

When something breaks, and after reading this article, I think you can determine it yourself, when going to the store for a replacement, be sure to take the broken device with you. This is especially important for people who are far enough from technology. Indeed, in our time, you will be sold anything without a twinge of conscience. They will hardly care what kind of RAM you need (will fit your motherboard). With a smile on his face and with the words “Take it! This is the newest RAM. Better yet not invented! ”, You will be sold the newest, most expensive and most unnecessary for your computer.

In conclusion, I will say that I have done computer repairs with my own hands more than once. Friends and acquaintances often ask about this. We have sorted out all the main points. There is no point in fixing the rest of the faults. What is broken in a computer cannot be repaired without special education and equipment.Nothing lasts forever, all computer components have their own resource. The majority, by the way, will not run out of this resource even by the moment when they are completely obsolete. I have an old computer, it is over thirteen years old. During this time, only the coolers have changed in it, the buzzing was too loud. At one time, it was an expensive and very worthy purchase, but now, after so many years, most of us have mobile phones at times greater performance than that computer.

I would be very grateful if you share this article with your friends on social networks and blogs, it will be great to help my blog develop:

No technique, even the most expensive, is everlasting. Therefore, no matter how sad it may sound, in any case, someday your computer will fail. No, it can turn on and work somehow, but we don't want to work on a PC that freezes and slows down every minute? The problem needs to be addressed. By the way, if you still have a warranty period, and you are sure that you yourself did not contribute to the breakdown, without further hesitation, hand over the equipment under warranty. Otherwise, check out the article thanks to which you will find out how to fix a computer with your own hands.

First of all, there is no need to immediately look for mechanical damage. It is possible that your computer freezes or does not work very well solely due to malware (users encounter such a nuisance very often). Also, the reason may be in some drivers that are not suitable for your system. Or due to the fact that you have installed some important, but unlicensed version of the program. In any case, first make sure that there are no viruses on the PC; this can be done using Kaspersky or a simpler utility - DrWeb Cureit. Next, clean your computer from various unnecessary files using the popular program - Ccleaner. This can cause the PC to seriously freeze.

Attention! If you need to disassemble the system unit, then in no case should it be done until you turn off the power. This is very easy to do - you just need to unplug the power cord. If you can, I suggest you get an ESD wrist strap. It will be safer for you to work with, but this item is optional.

Computer power supply - a very "vulnerable" thing that can fail at the most inopportune moment. The fact is that it is this very thing that regulates nutrition, stabilizes it in the event of unexpected changes. But if suddenly your voltage is constantly jumping, then this stabilizer will simply burn out. How not to face such a problem? Do not use an unreliable power source. Purchase a "Pilot" that will control the power supply, act as its fuse in case of surges. Bad weather, namely a thunderstorm, can not only destroy our power supply, but also "walk" through all other devices connected to the network. So, be sure to turn off the computer at such times. But if you have a laptop and you work with it offline during such weather, then there is nothing to worry about.

In some cases, RAM can let us down. There is, of course, a special program for checking it (MemTest), but you should not rely entirely on its verification results. If you need to check the memory performance with a 100% guarantee, then install another memory bar that works for sure. Thus, having at hand one, or better several planks, we will definitely be able to make sure which of them is working and which is not.

The hard drive, of course, does not break so often, but still with such a problem as hard drive recoveryevery user may encounter. It is very easy to understand that the reason for a PC malfunction is in the HDD. When you turn on the computer, pay attention to what "notifications" the BIOS gives us.For example, if the hard drive is not working, then when the PC is turned on, we will see the following warning: "Select Proper Boot Device". Sometimes there may not be any notifications, but the external signs of a breakdown will be "on the face". The hard disk can sometimes make too strange sounds, in some cases it stops working, then works again. In the event of a breakdown, the user can also hear something like a crunch, crackle, and so on. If your disk is working, but you notice such external signs, urgently copy all your data to the media, because soon you will not get access to the HDD. We will not bother with the repair of such a spare part. So feel free to go to the store and buy a new disk, and I advise you to pay attention to SDD, not HDD. This type of hard disk works much faster, and most importantly, this work will not distract you with its noise.

No matter how silly it may sound, but even because of the most common button used to turn the PC on and off, you may experience a breakdown. The fact is that if the contacts are slightly damaged, or the button is too close to these contacts, the system will recognize the computer shutdown and shutdown signal. Thus, the user can disassemble the entire PC and not even guess that the cause of the breakdown lies before his eyes. So be sure to make sure everything is in order with this part (check the contacts).

We will have really serious problems with the PC in the event that the motherboard "flies". And here even the breakdown will not be in the board itself, but in the digital tracks on this spare part. The assembly of the motherboard is important here. For example, very often the board can be connected to the processor heatsinks not directly, as it should be, but using a separate connector. And when the PC is diagnosed (it needs to be done every year), you have to constantly "push back" the radiator, and that is not easy to do. Naturally, with such efforts, the board wears out. Small and imperceptible cracks appear. Now manufacturers are already quite serious about the protection of the board, but nevertheless, each of you can face such a problem. In this case, there is nothing left but to purchase a new motherboard. Because under the guarantee they will not accept such a PC from us, because the board was actually damaged by us.

If suddenly, when parsing the block, you saw that you have such a situation from the motherboard, this mount will need to be replaced with a direct connection of the heatsink to the board.

When you turn on the PC, there is a small but loud enough sound (bios signals). Many users believe that this is "just the way it should be," and this sound does not tell us anything. But in reality, if we hear one signal, then everything is fine with the PC, the whole system works without interruption, and while working with the computer, we should not have any troubles. This check is carried out by a special built-in program.

What if a series of signals sounded at once? Or there was one, but very long. This signal, which, by the way, is emitted by the BIOS, is simply impossible not to notice. In this case, we clearly have some problems with the software, but which ones, let's try to figure this out.

Basically, manufacturers put one of 2 BIOS versions on ordinary computers: either AMI or Award. The signals for the two versions are the same, but the reasons for these sounds are completely different. So first you need to figure out what kind of BIOS we have. Before Windows boots up, a small window will appear, at the bottom of which it will be written how we start BIOS. In most cases, you need to either press the F2 key or Delete.

As soon as we got into BIOS after pressing the specified button, the following appears in front of us:

Above, the version of our BIOS immediately catches the eye.As you can see, I have an Award.

Also, do not forget that before starting to repair your computer, it is advisable to clean it from the dust accumulated in it. Sometimes, after this simple procedure, the computer gets a new life and does not need to be repaired. But even if our computer continues to suffer from various problems, you must admit that fiddling with a clean system unit is much more pleasant.

Dust and dirt inside a computer is often the source of problems in its operation, and sometimes a complete failure of the entire system. It is difficult to give recommendations on the frequency of cleaning, since it strongly depends on the environmental conditions and the design of the PC system unit. I recommend at least once a year to remove the cover and look inside the system unit. For cleaning from dust, it is advisable to open both covers.

To remove, the covers must be pushed back a little. The inside of the computer can only be cleaned dry using a small brush and a vacuum cleaner. The size of the brush is no more than 20 mm and it is better to use it with a flat working part and a hair length of 30-40 mm to freely penetrate through the fan blades.

The system unit is placed on a table or flat on the floor, first pulling out the power cord from the power supply connector. The rest of the wires can be disconnected, but not necessary if their length allows. When cleaning from dust, first of all, you need to pay attention to the cooling system and the processor fan, since the radiator is very often clogged with dust, dirt, wool, this can cause the processor to overheat. You also need to clean the motherboard and all fans and heatsinks on it.

Another crucial place is the video card, many of which have their own axial fan. Sometimes there is so much dirt under it that it gets stuck and burns out because of this, and most likely the video card will go the same way. It is better to remove it and clean it thoroughly.

Sometimes the cause of operating system glitches is also contamination of memory modules, especially the one closer to the processor.

It is unforgettable that a huge amount of dust accumulates in the power supply fan during operation. It is even advisable to unscrew the power supply, unscrew the cover and clean it with a brush and a vacuum cleaner, and then assemble and install it in place. But if you are afraid to perform switching, then you can simply fold the power supply on the wires and remove the cover.

If you are too lazy to bother, then through the ventilation holes you can at least suck out the dust with a vacuum cleaner at maximum power.

Never wipe the dust inside the system unit with a cloth, especially if it is damp. Do not use sharp objects or lose anything, especially various metal objects inside the system unit.

Many have a large black box on their computer desk called a personal computer system unit. Let's open it up and deal with its structure and stuffing.

The central processing unit, or CPU, is the heart of any computer or laptop. It is he who executes all the commands sent by the user or the operating system, processes all the information and controls all the devices on the computer.

The principles of the structure and operation of the motherboard are described. From the article you will find out what connectors are on the motherboard, how to check it and find out what exactly the problem is, as well as some secrets of repairing the motherboard with your own hands.

CPU-Z - a program that reveals detailed information about the processor, memory, cache and motherboard available in the computer.
Easy Recovery - for data recovery and diagnostics of hard drives and others

Individual users have difficulty connecting a conventional computer system unit. Sometimes, due to connection errors or a poorly inserted connector, the computer may refuse to work at all.In general, the operation of connecting the system unit is not at all difficult, but there are some specific points in which it is easy to make a mistake.

The processor and video card in the computer must be provided with conditions for high-quality cooling, especially on hot summer days. Good cooling, in addition to removing hot air through a cooler, is also created with the help of a thermal interface, which is also thermal paste.

The easiest way to make sure that the power supply is working is to change it to a similar one, how to do this and then how to repair the old one, we will find out by reading this article

The power supply unit of a personal computer is designed for uninterrupted supply of electricity to the entire system unit and all its components. Therefore, the failure of this unit completely de-energizes the computer and it usually stops turning on. A malfunctioning computer power supply is the main cause of various "freezes", blue screens and errors of the operating system and other programs, therefore, first of all, you need to check this particular unit. The algorithm for cleaning a laptop from dust is somewhat different, but you can do it yourself.

The video card in the system unit is designed to work with graphics, that is, it performs the functions of processing and displaying images on the monitor display. A modern video card has its own RAM, a graphics processor and an interface bus through which data is exchanged with the central processor and computer RAM.

BIOS is an abbreviation for Basic Input Output System, which in English means Basic Input Output System. The main task of the BIOS is to ensure the correct functioning of the hardware of a computer or laptop, under the control of the operating system. BIOS is a set of functional firmware located in a specialized non-volatile memory CMOS chip.

In order for a laptop or computer to work optimally and quickly, periodic maintenance of the laptop by software is required. Service in this case means the use of specialized utilities and programs.

Decoding of codes for BIOSes of the following manufacturers: AMI BIOS (AMIBIOS8), Award BIOS, Phoenix BIOS and others

A very important point in the maintenance and software repair of a laptop or computer is knowledge and skills in cleaning the Windows registry, which is a hierarchical database of settings and various parameters of the operating system. The registry is a place where information about settings and configurations of hardware and software, user profiles and presets, information about installed utilities and their changes are stored. The registry can be represented as a directory, which briefly describes what, where and how it is stored, what parameters it has and how it all interacts with each other.

During the repair of computers and laptops, they often do preventive cleaning from dust and replace the old thermal paste. Sometimes dried thermal grease can stick to the heatsink. It turns out that you planned to remove the heatsink to replace the thermal paste, but it is removed along with the processor.

If your computer or laptop that has been working for 2 years or more began to suddenly glitch or freeze, then it is worth examining its motherboard for swollen capacitors. In this article, we will try to answer the question about the correct replacement of capacitors on the motherboard and in what cases should this be done?

How easy it is to fix a computer mouse. After many years of hard work and intense exploits at work, my A4tech X-710F handheld computer rodent has decided to retire. But it wasn’t there, I didn’t want to spend money, and not only because there wasn’t, but also because I’m just used to it.

The causes of malfunction and problems of an inkjet printer are very often not a breakdown that requires the intervention of a service engineer and disassembly of the printer and can well be eliminated by the efforts of an ordinary user. The symptoms of inkjet printer failure can be roughly divided into two groups.

To create a local network or connect to the Internet, you will need to connect the network cards of computers and switching devices using a network cable. And the cable is connected to the network adapter using special RJ45 connectors, which are installed on the network cable using a twisted pair crimp.

Hello dear readers of the blog my.housecope.com/wp-content/uploads/ext/654

While working on a personal computer, few people think about its technical condition. The user is far from thinking about whether the power supply is sufficient for the connected devices, whether the expansion boards are securely screwed in, and about elementary prevention.

It all starts from the moment a personal computer fails. This happens suddenly and at the right time, when you urgently need to print the most important document, your PC refuses to turn on. In order to be prepared for emergency situations and in the shortest possible time to help solve difficulties, it is necessary to learn the basic techniques associated with troubleshooting. In order to localize the cause of the failure, it is necessary to perform a number of actions.

1. Check the power cord connections to the network and to the system unit.

2. Check the monitor connections to the system unit and to the electrical network. When connected to a network and the computer is off, the indicator on the monitor should be on.

3. If the PC did not turn on successfully, then it is necessary to turn off all devices as much as possible, leaving only the monitor, keyboard and mouse. If no image appears on the display and the computer appears to be on, i.e. the indicators on the case of the system unit flicker and the characteristic familiar sounds of fans and other devices are heard, then it is necessary to carry out a number of actions. Disconnect the power supply. Remove the left side cover of the system unit. Remove video adapter. Use an eraser to clean the contacts and insert the video card back into the PCI-Ex slot. If there is no positive image output to the monitor, you need to remove the video adapter from the system board and connect the monitor interface cable to the integrated video card. If a familiar boot image appears on the monitor after switching on, then it’s time to change (or upgrade) the video card.

4. In the case when, after turning on the power, the system fans begin to rotate, and the small speaker on the motherboard emits a characteristic squeak, then the problem is most likely in the RAM. If more than one strips are installed in the slots on the motherboard, then it is necessary to remove as much as possible, leaving one. Cleaning the contacts with an eraser can be beneficial. Using the brute-force method, it will be easy to identify a non-working RAM bar.

5. Quite a common case is the absence of any reaction of the personal computer to pressing the Power button. There are several possible scenarios for the development of events. There is no contact with the mains (the plug is not firmly inserted), or the power cord is broken, or there is a malfunction in the power supply. Failure of the power supply is a common reaction of the system unit to power surges, as well as the connection of devices that consume more power specified in the characteristics of the existing power supply. Modern practice shows that replacing the described element is a more economical and reliable option than repairing.

6. If the personal computer turns on, but the operating shell is unstable, the launched applications work slowly, then the solution, most likely, does not lie in the hardware part.The data available on the hard disk, like any device, needs to be prevented. Periodic defragmentation of data, cleaning the registry, and even reinstalling the operating system will not be superfluous. Taking a little time for preventive measures, you will save yourself from periodic system freezes and workload of your PC. Having an understanding of the features of the basic elements of a personal computer, you can easily solve the difficulties that have arisen, or even prevent them.

That's all for now, everyone, and until new interesting meetings with you.
