One of the reasons that requires the recovery of Windows is registry corruption. This happens infrequently. Sometimes the computer user can mistakenly corrupt the registry.
The Windows Registry or the Windows Registry is a hierarchically constructed database of settings and settings on most Microsoft Windows operating systems.
The registry contains information and settings for hardware, software, user profiles, presets. Most of the changes in the Control Panel, file associations, system policies, the list of installed software are fixed in the registry.
After you install Windows on a disk, the following files are stored in the% SystemRoot% \ System32 \ Config \ directory (for example, C: \ Windows \ System32 \ Config \):
(All files (file names) without extensions: A copy of these files is stored in the C: \ Windows \ Repair \ directory)
In addition, the files used to build a “working version” of the registry can be stored in directories:
% SystemDrive% \ Documents and Settings \ <Username> \ – the file “Ntuser.dat”
% SystemDrive% \ Documents and Settings \ <Username> \ Local Settings \ Application Data \ Microsoft \ Windows \ – the file “UsrClass.dat”
It is obvious that as the user works, mistakes are accumulated in the registry, including for the reasons listed above. In this regard, the registry is prone to damage from both programs and viruses.
In order to avoid this, it is necessary to regularly check the disk for errors, viruses; checking the registry for errors and defragmenting it.
To edit the registry manually, the system utility regedit.exe is used.
Reasons for rebooting the computer
The reasons listed above usually lead either to the computer crashing, rebooting (with some Trojans and viruses) or to being unable to work properly.
The same symptoms can also be caused by hardware malfunctions – overheating, bad sectors on the hard disk, and “glitches” of RAM, but we’ll talk about this in a separate article.
Most software problems are caused by corrupted system files or Windows settings, due to viruses, and if the registry is damaged.
Consider the causes of these injuries.
Damage to system files
The fact is that most programs use standard Windows system libraries (files with the extension * .dll) for go, to reduce the amount of the actual program. If these libraries are damaged, the installed programs can not work correctly.
Sometimes there are situations when with frequent installation and removal of programs, some system files (* .sys) and libraries can also be uninstalled with them. This can happen when the program overwrites (overwrites) the original system file by installing it on its own.
In order to avoid this, it is necessary to install as few programs as possible and experiment on the working system by installing and removing programs.
There are also cases when, when several programs or processes run, a collision occurs – an attempt to simultaneously access several programs or processes to the same resource (file). This situation is called a deadlock or mutual interlocks.
Deadlock is a situation in a multi-tasking environment or a DBMS, in which several processes are in a state of infinite waiting for resources captured by these processes themselves. Often such situations lead to the hang of programs.
I want to note that hangs also occur when the kernel of the operating system tries to switch from one process to another, but for some reason can not (for example, the started process hinders it). Visit our website and let me remind you that in multitasking operating systems, all processes are performed in turn – the processor once every 25-100 ms switches from one task to another. At the same time, processes can not be performed. In this situation, it is recommended that you wait a few minutes before the automatic unlock. If this does not help – try to “kill” the process via Ctrl + Alt + Del.
Windows settings due to viruses failed
Most of the time, configuration failures result from the penetration of viruses or Trojans into the system. Those are started as programs in startup or as services that can not be seen, but they prevent the change of Windows ntraznek.
Symptoms of infection with viruses and trojans are the following indirect signs:
strange windows appear after which the computer turns off or reboots
there’s no way to change Windows settings
there is no possibility to remove / install programs
there is no way to view hidden files and folders
you change the system settings, and they are not saved
New items appeared in the right-click menu of the mouse
folders do not open as before
periodically Windows tries to connect to the Internet or open there any site
The main sources of viruses are the Internet (namely, dangerous sites with free software, music, movies, pictures, entertainment sites), local networks (mostly large type Matrix), flash drives.
The recommendations are simple: to use anti-virus protection, firewalls, antitrays.
There are a lot of ways to clean and restore the system: use the “System Restore” utility (rollback), Recovery Console, in especially severe cases – use Windows Live CD and special utilities to clean the system.
It’s been more than a year since Seagate’s new line of Seagate Barracuda 7200.11 disks appeared in one of the leaders in the production of hard disks – Seagate.
These disks have a density of 250 and 320 gigabytes per plate and a spindle rotation speed of 7200 rpm. In addition, they have a fundamentally new design of the control firmware. All Seagate drives of the older series were based on the principles developed by the engineers of Conner Peripherals, which Seagate acquired in 1995. As for the drives from the new line of Seagate, they represent a blending of these old principles with the SCSI architecture.
It is because of this in the new family of drives there are no models with a PATA interface, and there are only models with a SATA and SAS interface. Unfortunately, the first “pancake” turned out to be “lumpy” – the new family inherited both a number of old flaws in the Konner models, and a number of new specific “sores”.
One of these “sores” manifests itself very often and consists in damage to the official disk information. It manifests itself in two very similar ways: the disk either is not detected in the BIOS of the computer at all, or is determined, but as a drive with zero volume.
The disks that have caused this malfunction began to arrive in the guarantee departments of the vendor companies and were successfully replaced under the warranty for new ones. But, unfortunately, the user lost his data stored on the “lost” disk.
Therefore, we consider here the methods of electronic service, data recovery, applicable at home, with typical faults that occur in the discs of a new family.
As the study showed, the disks either damage the part of the translation table that is responsible for the G-List, in which case the disk is determined by the volume 0, or the contents of the S.M.A.R.T table corrupt.
In the first case, to restore the disk and gain access to the information on it, it is necessary to restore the translation table by recounting it from the defect sheets. However, when recalculating, it is important that defects from the G-List are not transferred to the P-List. (The specifics of the device defect sheets and hard disk drive systems are discussed in our previous articles).
How to do it? Although the disk family is new, it inherited something from the old Konner family. This “something” is the control interface RS-232. To restore the service information, we will use it.
The computer (and all its devices) is entered in the register of special products as a complex technical device. Of course, this register primarily deals with the relationship of sellers and buyers, but this relationship extends to people who are professionally engaged in the repair of personal computers.
Unfortunately, the world has not yet invented non-breaking things, so sooner or later any computer owner will have to face the problem of a broken PC. There are two main groups of faults in the computer: software and hardware.
Trouble with the software, as a rule, is solved quite quickly and easily: it is enough to call a specialist, and he will solve the problem in just one or two hours. There is nothing complicated in this, but even here you can face scammers.
First, you may be required to pay for the restoration of the required files. In principle, this is normal, but it is necessary to know that the data is flown from the C drive, and if they are located on other, additional disks, then they will remain there, and you will pay for the work that you did not do and did not have to do.
Secondly, specialists, using ignorance of the townsfolk, often wind up prices, exaggerate the amount of necessary work and thus profit. Thirdly, a very common type of fraud is the installation of pirated copies under the guise of licensed programs and taking money for them in full. Therefore, try to check all the programs that are installed on your computer.
Well, fourthly, scammers can say that the problem is not in the software, but in the equipment, since the repair of equipment is much more expensive thing (especially with the replacement of damaged parts). In this case, ask for repairs in your presence.
How can you tell a fraudster from a specialist? Here you can advise to do two things:
1) when calling, ask about the presence of a certificate – the specialist must respond immediately, and the fraudster hesitates;
2) look at the newspapers over the past year – if there is an advertisement of this person in them, then he is probably a specialist (scammers, as a rule, work simultaneously).
Try to learn how to independently identify problems with software from hardware problems. With some experience this will allow you to save a lot of time and nerves.
Now let’s talk a little about repairing the equipment. In this case, calling the master at home is not the best option. It will only be useful as a diagnostic tool to determine that the problem is not in the software. It is best to contact a company specializing in computer repair. However, there are some subtleties here, and you can face fraud.
Therefore, before you give your system unit, rewrite the numbers of all the components, and after the replacements made (if they were, of course), be sure to require the old parts back. Otherwise, under your fictitious pretext, you can completely replace the workpiece and take money from you for it. Remember, there is no excess reinsurance!
Article for those who want to open their electronics business, to earn money on repairing phones, laptops, tablets and computers. Practical advice from the business owner watch on this official website.
Hello, my name is John, I’m the founder of a network of service centers for the repair of telephones, laptops, photo and video equipment.
I have a video on youtube channel about how to open my service center, where I tell you what you will need directly to open.
But before you start to open your first workshop or service center, it’s worth doing some preparatory work, without which your grand opening slowly goes into a sad closing and calculation of losses.
The first thing to begin with is to clearly prioritize. Understand what is most important in this business, and what is secondary. Without which knowledge and skills you can not build a profitable business, and without which knowledge you can do at all.
What do you think is the most important thing in the electronics business?
– Skills and experience in repairing modern technology? – No
-Access to suppliers of original spare parts and the lowest prices for parts? – No
– Own premises and start-up capital? -Also no.
The most important thing in this business and in any other is the skills of attracting customers: lidogeneratsiya, marketing, as it is now just not called. If you do not have customers, then everything else does not matter.
Someone will object: “Well, if my company does not perform repairs properly, we will have high prices, poor quality of spare parts, so, accordingly, customers will not come to us either.”
Yes, all this is certainly important, but not primarily, what will your service level mean if you can not create a flow of customers, who will evaluate it? 1-2 customers a day and even then, even such a number of orders for many new open repair shops for phones and laptops is in practice unattainable.
These guys are many, open, work a month or two in the minus and close.
To what I tell all this, before you start your business, you should definitely get training in the course of web marketing, business analytics, get at least basic knowledge in contextual advertising, SEO, get acquainted with all existing channels of attracting customers.
Such knowledge you can get both independently from free sources on the Internet, and to pass paid training, thank God now educational programs on this subject are missing.
So, the first and most important thing is to acquire knowledge in web marketing, to become a good specialist yourself.
In second place in importance, obtaining practical knowledge and experience in the operating activities of the sphere in which you want to open a business.
If you did not work in a similar service center, for example, you worked at a printer repair center, but you want to open a repair shop for laptops and phones. Then I strongly recommend that you first get a job on the right profile, work at least six months.
Because everywhere there are many nuances, so-called, reefs, which you should know.
And the last tip: in parallel with the training, start developing the site, in advance, think out the design, structure, correspondence to the simantic core of the pages of your future resource. Choose a good old trust domain, choose the right engine and a lot of other nuances about which you will learn at school and in parallel will begin to apply in practice.
As a result, you will have to install a program for keeping records in the workshop (I recommend the Gincore program), find a good room, buy equipment, furniture and sign.
This is how the founder of a successful service center should spend six months before opening it: the day at work in the service, in the evening at the courses on web marketing, at the weekend – creating website.
Agree, it’s not very pleasant when a computer lags and nothing can be done on it. And to find out the reason at times is not so easy, because there can be a lot of them. But in this article we will analyze all the main reasons and try to eliminate logs from the computer.
So what do you need to do in order not to lag the computer? Carefully read the tips listed below. Perhaps to eliminate lags you need to use several of the listed tips, because using one is unlikely to help.
▶ Check your computer for viruses.
What’s the first thing that comes to mind when the computer starts to lag? Of course, this is the presence of all kinds of viruses, trojans, worms, so first of all you need to check your computer for malware. You can use one-time scanners, the best is Dr.Web CureIt, the link above will find where to download and how to use this antivirus scanner. Viruses are the main cause of computer lags, so I do not advise you to miss this point, but to use it first.
▶ Clean the system of debris.
If it turned out that the computer is not infected with viruses (you scanned the system before, of course), then the next reason for computer lags can be unnecessary files and any garbage in the system. Programs cleaners there is not enough, but perhaps best of all with this problem cope CCleaner.
▶ Remove unnecessary programs.
Are there many programs that you do not use? Remove them. Article, how to properly remove unnecessary programs, you will help. Remove without regretting any Yandex.Bar and Satellites@Mail.Ru, which are sometimes secretly installed when installing other programs.
▶ Clean the registry.
After cleaning the garbage, it is also necessary to clean the OS registry. After any manipulation in the system, the registry leaves all unnecessary branches, which can cause lags of the computer. To do this, you need to clean the registry, as described in the article on the link above. Warning: before editing the registry, it is recommended that you create a backup copy of it so that you can quickly restore everything from backup.
▶ Defragment the HDD.
You can read about the defragmentation of hard disk in this article, everything is described here, what it is and how to use it. If you do not do defragmentation for a long time, then the hard disk lags may appear. I just want to say that this can prolong the life of the hard drive, not the SSD, namely the hard drive (HDD), although the logs may not be so serious, this can lead to a low speed of writing / reading the hard drive.
▶ Remove programs from startup.
When you turn on the computer, many programs and utilities are automatically loaded with the operating system. It is recommended that you uninstall programs from startup that prevent the system from booting normally.
By default, in Windows, you can remove programs from startup as follows:
1. Start the context menu “Run” (Start-Run), or by using the Windows key combination “Win + R”.
2. In the dialog box enter the msconfig command, click on the OK button.
3. In the window that opens, go to the “Startup” tab.
Now only it is required to remove the tick from those programs that should not be run with Windows.
Unfortunately, this way you can not remove all programs. The easiest way to do this is with CCleaner, which gives you access to a complete list of installed programs on your computer.
Like programs, Windows services can cause lags when they are launched a lot. Therefore, you need to disable unnecessary services.
Disable superfluous services it is possible as well as to remove programs from autoloading, only it will be necessary to pass to a tab “Services”. Now, in the same way as in the paragraph above, disable unnecessary services in vain downloading the system.
▶ Check the hard disk for errors.
The cause of the lag may be a malfunction of the computer’s hard drive. For this, it is necessary to check the HDD for errors by the utility CHKDSK, which is installed by default on the Windows operating system. Of course, you can use third-party utilities, such as MHDD or a powerful Victoria program.
▶ Clean the computer of dust.
Dust is very dangerous for computer equipment. And lag computer can because of dust, first you need to measure the temperature of the computer components – as described in this article (there you can find the optimal temperature of each component). Further, if overheating of a component is noticed, measures need to be taken. In this case, if there is overheating, you will have to clean the computer of dust, as described in this article, but here is an example of a laptop there, but I do not think there will be any problems with the system unit either. That’s all.
How can I live without computers, smartphones and other gadgets today? Even more difficult to realize is that 50 years ago, these technologies could only be learned from science fiction books.
The first computers were created after the end of World War II. They were very large and expensive (they cost even more than the latest version of the modern MacBook). Therefore, only such employees of serious organizations, banks or leading universities could play such toys. But the development of home PCs (personal computers) was in the second half of the twentieth century. The first one is a PDP-8 mini-computer. It was released in March 1965, it was done by the corporation Digital Equipment Corporation.
It should be noted that when we call the PDP-8 a mini-computer, we mean that it did not occupy the entire room. PDP-8 was no more than a regular refrigerator, which for our time sounds pretty wild. Its price was $ 18500, but this did not prevent computer enthusiasts from buying this miracle of technology. Therefore PDP-8 became not only the first home PC, but also the first commercially successful computer.
The next “breakthrough” was made by the company MITS, when in 1975 it released the computer Altair 8800. It is considered one of the “revolutionaries” of home PCs, as well as the first step in the formation of companies manufacturing personal computers.
What is the secret of Altair 8800? It was compact, productive and inexpensive. For only $ 439 each person could purchase parts for the computer and collect it using the magazine Popular Electronics. For 621 $ it was possible to receive already ready model. Altair 8800 had an Intel 8080 microprocessor with a clock speed of 2 MHz, and also processed 8 and 16-bit numbers. By the way, Bill Gates started his career precisely thanks to Altair 8800!
At the same time, two more computer enthusiasts – Steve Jobs and Steve Wozniak – decided to create a company that would develop computer technology. Their truly revolutionary project can be called Apple II, which appeared in 1977. Jobs and Wozniak demonstrated how a general-purpose computer should be. Since that time, technicians could be used not only by enthusiasts or amateurs, but also by ordinary citizens.
IBM PC 5150
In 1981, IBM joined the mass excitement and released IBM PC 5150, which probably still can be found in some government agencies.
The computer is considered one of the most successful home PCs in the world. In total, 20 million devices were sold. The PC was equipped with a MOS 6510 processor. It could also be connected to a TV and used as a game console.
The next successful product of Apple was Macintosh, which finally determined the type of personal computer. The main innovations that the product sported were a mouse and a completely graphical interface. In fact, this is the great-grandfather of all modern iMacs and MacBooks. And this is the first computer that greeted its future users.
IBM PC Convertible
IBM PC Convertible is the first laptop in the world, which was introduced by IBM in 1986. It had an Intel 80S88 processor and 256 KB of RAM, which could be expanded to 512 KB. Also the laptop could boast of two disk drives and a modem. The PC was sold very poorly. It was heavy, not fast enough, and it was not easy to read from a liquid crystal monitor. IBM PC Convertible still remains the first laptop that was released in mass production and influenced the further development of the industry.
A little bit about the future
Technologies do not cease to develop. Now most companies are trying to create high-performance computers that would not take up much space. Leading is Apple, whose products over the past decade has gained immense popularity in all corners of the Earth.
Large personal computers are beginning to give way to ultra-thin laptops and tablets (although there are still enthusiasts who independently assemble and upgrade their PCs). According to forecasts of specialists, in 100 years the functions of a laptop or PC will be performed by smart watches, smartphones and holographphones, and powerful computers will be used to calculate large amounts of information.
Have you ever encountered the fact that your video card stopped working? God grant, of course, that this never happened, but still! What to do, for example, if you hear that the computer is being booted, but there is no image on the monitor (black screen)?
What we usually do in such cases: substituting a workable graphics card (or switching to an integrated video) and making sure that the problems are with the graphics adapter. But what to do in this case? Can we independently repair the video card?
The good news is that “yes”: repairing the video card with your own hands is quite possible! The bad thing is that after such a repair there is no guarantee that the video card thus restored will work for a long time. Also, the repair itself can fail if we do not follow certain rules. But let’s take everything in order!
So, we have a non-working video card from the company “Nvidia”, the model “GeForce 9500 GT”.
The problem is what? The video card worked for a long time under severe temperature conditions, which led to its overheating. As a result, there was a fairly typical (in such cases) thing: the “blade” of the BGA chip of the video card.
Do not be frightened by the word “dump”, nothing has fallen off there 🙂 Just because people call the resulting, as a result of prolonged overheating, violation of the electrical contact of the array of BGA beads with the printed circuit board card. Typically, this phenomenon occurs as a result of the presence of a small area of cold soldering, which is subjected to prolonged and severe heating.
It can not be said that this is a 100% marriage of the manufacturer: there can be a lot of tin balls in the array and a violation (or oxidation) of contact of even one of them can lead to a complete (or partial) loss of the card’s performance. So overheating, whether it’s a video card or a CPU is a very unpleasant thing. Try to not allow it in all possible ways!
And in this situation, we have nothing to do but try to repair the video card with our own hands, on our own. So, first of all we need to take care of removing from the card all the plastic stubs on it, stickers (stickers) located on the back side. Everything that is in the area of the graphics chip and can melt.
Video card from the back
Yes Yes! You did not mishear: it is to melt. After all, we will repair the video card by heating it and all the “extra” you need, for every fireman, to remove. Of course, perhaps nothing like this will happen, but just take it into your habit – it will come in handy 🙂
Also we need to remove the fan and the cooling system. We do this by what is more convenient for us. Remove the cooling system
As you can see, the cooling system requires thorough cleaning, and the fan itself needs to be prevented, since its efficiency has decreased because of the lime adhering to the blades and the dust that has accumulated in the bearing.
It would seem: what is difficult? But, as one movie hero in the movie said about the different evil spirits: “everywhere there is a catch!” Here it consists that often (especially if the chip was operated in a rigid temperature mode), having dried, the thermal paste firmly glues together the crystal and the radiator.
Categorically it is not recommended, in this case, to use the power of heroic and pull this thing to oneself or, as the experience suggests, to cheat something! So you can damage the crystal! There is a simpler and more elegant solution: we take an ordinary household hair dryer and, slowly, warm up the clutch area.
After a while (seconds 5-10), we begin to slightly sway the radiator from side to side, as in the photo above. Thermal grease, softening under the influence of temperature, will allow us to do this. A little warming up this matter, we easily separate our radiator from the crystal:
Try to clean out as much as possible and as accurately as possible from the remains of the old dried thermopaste as the “soleplate” of the radiator, and the crystal itself. Try not to scratch the metal surface of the radiator (this will reduce the coefficient of its heat transfer). Do not scrape, better warm up separately and wipe off the old paste.
With the crystal is also very accurate: if you can not remove some of the paste (like me, for example), then leave it. All that is erased – always delete! Otherwise, thermal paste under the influence of temperature, as they say, “bake” and then it will be very difficult to remove without damaging (chipping) the core itself.
Why did I highlight some areas in the photo above? Look, the big area is the chip of the graphic card itself, and the smaller one is the GPU (graphics processing unit). On the perimeter of the crystal, we see a white sealant (compound), which performs several functions: protects the crystal from getting under it dust and fixes it to the substrate.
What is the “trick” here and why does the repair of the video card with its own hands could end unsuccessfully, no matter what efforts we make? The platform (array) of BGA solder balls is not only between the chip itself and the PCB textolite, but also between the crystal and the substrate of the graphic card!
The harsh reality is that we can repair the graphics card ourselves (if we are still lucky) only if there is a violation of the balls’ contact directly between the printed circuit board and the substrate. In the case if the “dump” occurred under the crystal, then there is hardly anything we can do. Even such an operation as reballing (complete replacement of the array of balls with a stencil) in this case will not save, because this procedure is performed only for the “sole” of the entire chip, but not the crystal!
So, I hope, we learned the necessary minimum of the theory? We move on! To repair the video card at home, we will need a flux and a disposable syringe. I use the usual GFR (spirtoknifolnym), which is called: “GFR-flux.”
One of the most important parts of your computer is the motherboard. However, its name speaks for itself. After all, it depends on it, what equipment you can install on your personal computer. The motherboard not only connects all other parts of the computer, but also coordinates their work and distributes the electricity that is fed to it from the power supply. Now a few words about what the motherboard consists of.
The first and most important component can definitely be called a chipset. It is a complex of microcircuits and determines the configuration of the computer as a whole. However, the chipset is present in any technique that uses electronics.
The chipset itself consists of the south and north bridges. The North Bridge is responsible for the operation of the processor, RAM and video card. For all other resources (hard disks, network card, USB ports, etc., etc.) is responsible for the south bridge. It directly depends on the chipset which processor the processor will be in, because if they are incompatible, the computer simply will not work. As a rule, the processor and chipset belonging to the same manufacturer firm are compatible, but there are relatively universal chipsets that can work with a large number of processors.
Thus, the technical parameters of the chipset affect the performance of the entire motherboard – performance, capacity and, accordingly, its price.
An equally important part of the motherboard is the RAM.
Over the years of the development of the computer industry, many different modifications of RAM have been replaced. Now in new assemblies use the DDR2 and DDR3 memory. To be more precise, either DDR2 or DDR3, depending on the configuration of the motherboard. At the same time they can not be used.
Do not forget about the video card. As the name implies, the video card is responsible for the quality of graphics on the computer. Therefore, users who need very good image quality (for example, those who professionally work with graphic editors or simply like beautiful computer games that require a good graphic resolution), often put themselves on the motherboard for another, an additional video card. Depending on the power, the video cards may differ in size.
This is due to the fact that large capacities require a more serious cooling system, so that the graphics card does not overheat. If you also want to put the second video card in the computer, first make sure that it fits your motherboard by its configuration and size (sometimes the video card slots are quite close to each other and the second card may not fit). There are also motherboards with an integrated (built-in) graphics card.
Sound and network cards are usually built-in motherboards originally. However, if they are not available or if you need to install a more powerful card, you can purchase them separately. Of course, guided by the configuration of the motherboard. These cards are responsible, respectively, for the reproduction of sound and for the operation of the computer with the network (access to the Internet, connection to other computers).
The dimensions and location of the various ports describes the form factor. This is the name of the standard, which gives an idea of the spatial configuration of equipment. The standard is recommendatory in nature, however, most companies try to follow it when assembling, as it represents the optimal solutions for the configuration of equipment. Thus, each form of the mother card must have a certain form-factor of the computer case, and this must also be taken into account.
And finally, be sure to pay attention to the socket. A socket is a socket for connecting a processor. The connection occurs by inserting the socket feet into the holes on the processor. The number of legs and the size of the sockets of different models differ. Of course, certain models of sockets can serve to work with a limited number of kinds of processors.
In other words, if the processor to the socket does not fit, then you simply can not put it there, since the position of the legs will not correspond to the position of the holes on the processor. As an example, we can say that Intel processors work with LGA-type sockets (LGA1155, LGA1156, LGA1366, LGA775), and AMD processors, respectively, with AM (Socket AM3, Socket AM2 +) models.
Finally, I want to add that there are a lot of different configurations of motherboards. Their production is engaged in such brands as Intel, Gigabyte, Asus, Foxconn, MSI, Biostar. You do not have to single out any of them, they are all good in their own way. Because everyone chooses the computer (and accordingly, the motherboard) specifically for their needs. A properly selected motherboard will provide your computer with a long and reliable operation.
