Noise from the system unit is always a bad sign of computer operation. We should get rid of it not only because it irritates our ears, but it can also affect the performance of the computer, as well as the wear of parts. Today, in this article, you will learn why a computer (in particular, its system unit) is noisy and what needs to be done to remove excess noise, returning the computer to its previous sound level during operation.
7 reasons why the computer system unit is noisy
- Hard drive problem. The cause of the noise is the way the hard drive works. Moreover, it may not be noise, but crackling, grinding and even tapping. This is especially noticeable when you copy or write something to your hard drive. Such sounds indicate either wear of the mechanism or poor quality material. Therefore, noise can occur both after long and persistent use of a PC, and immediately after purchase. You should not delay this, because if the HDD completely fails, you will lose the files and documents stored on the computer forever and irrevocably. Therefore, you should choose a hard drive carefully, paying attention to reviews from other owners, as well as advice from sales consultants. Of course, our article about that is worth paying attention to.
- Dusty video card. This device always creates maximum noise, or even better, hum in the room. To be precise, the cooler (fan) that cools the board is most likely to blame. It is often small in diameter, but even one is enough to create a loud and unpleasant noise. It is usually located “upside down” and its blades can touch the edge of the video card box. It is quite difficult to avoid such noise; it is easier to install it in your system unit. You can solve the issue without buying a new device, but to do this you will need to disconnect the video card from the motherboard, and then disassemble it to get to the cooler and lubricate it, which is very problematic! Also remember that this component is very fragile and can be easily broken. If you still manage to get to the axle, then it needs to be checked for integrity, and then lubricated with silicone oil, which will remain inside the cooler for a long time and thereby prevent noise from occurring. If the axis has already shifted and torsion creates friction against the edges of the box, then the box can be slightly trimmed or sawed off. It won’t look very aesthetically pleasing, “but it will be cheap, reliable and practical” (c)!
- The processor cooler is clogged. Another reason that creates a lot of inconvenience for the computer user. As you know, any motherboard has a processor installed, which is also called a “stone,” and a radiator with a cooler is additionally installed on this stone. The created design is quite bulky and collects dust well, since the cooler blows air (from the system unit) to cool the radiator, which in turn transfers the temperature to the processor. As a result, a large layer of dust accumulates between the cooler and the radiator, which gradually grows, thereby complicating the movement of the fan. The dust layer adds extra noise, and it also gets into the axis, which causes the speed to be lost and a hum begins to be heard. It's very easy to get rid of everything! First, disconnect the fan, clean it and the radiator from dust. Now disassemble the radiator itself and lubricate the axle with the same silicone oil. Now put everything back together, tightening it thoroughly with screws so as not to create unnecessary vibration.
- Old power supply. The power supply is a device that is recommended to be changed every 2-3 years, since it is responsible for the safety of the entire PC. In addition, this time frame is just enough to dust all the internal parts of the power supply. After all, there is the same cooler that blows in air from outside to cool the parts as on the processor. The air carries particles of debris and dust. As a result, noise occurs in the same way as in the case of a video card or processor cooler. However, there can be much more noise here, since the rotation speed of the power supply cooler is higher, since its diameter is larger, and to be honest, not all manufacturers think about creating a quiet fan in the power supply. Of course, you can get rid of the noise yourself by disassembling the unit, cleaning it and lubricating it. But again, not all models have the ability to easily access content. The site’s specialists strongly advise purchasing a new power supply rather than disassembling the old one, because the new one will produce less noise and will give you additional confidence in the serviceability of this personal computer device.
- Incorrectly selected optical drive. Rarely, but it still happens that noise is created not by the entire system unit, but only by the optical drive, which is more familiar to users under the name “CD-DVD ROM”. The reason for the noise is the rather low quality of the device. However, be careful here, noise can only occur when a disc is inserted into the optical drive. If there is nothing there, then there will be no noise coming from it. If you notice noise precisely when this device is operating, then we have to disappoint you, because... it is practically beyond repair. Even in warranty service centers they are not repaired, but replaced with new ones. We would generally advise you to abandon their use in favor of flash drives, since today with the help of the latter you can carry out all the same operations, even .
- The motherboard or other device is cracked. Noise from the system unit can come not only due to flaws in the operation of the cooler or due to manufacturing defects, but also for completely physical reasons: a cracked motherboard, large debris in the system unit, a cracked video card box, etc. This will cause various kinds of rattling and whistling noises due to the effect of air pumped by coolers on the part. To do this, you need to disassemble the system unit and check its “internals” for defects. This could only happen due to a fall or an accidental/intentional blow. For example, many PC users, when they slow down, hit the system unit with their foot or hand out of anger. Such actions may cause chips, cracks, dents and similar defects.
- Poor fastening of parts. If you are asking the question “Why is the computer system unit noisy?”, then you need to check all the fasteners in the system unit. To do this, first open the unit cover. Now take a screwdriver (phillips) and try to tighten all the screws and screws that you can see. Start with the motherboard, since it contains a large number of components, so if each of them is poorly secured, then when they work, the “motherboard” will begin to move in waves, each time touching the metal case of the system unit. Next, check the fastening of the processor (especially the cooler) and video card. Then examine the hard drive mounting. If it does not have anti-noise fixation using slotted gaskets or plastic holders, then rest assured that the noise arises precisely because of poor fastening of the hard drive. Therefore, try to lay a small layer of rubber between the metal beams, which would soften the vibration without spreading it throughout the entire system unit. You also need to attach an optical drive. The last thing you need to check is the power supply. Tighten its mounting bolts as well. If there are additional coolers in the system unit case, check them too.
What to do to get rid of noise from the system unit?
If you don’t see any problems with the components, but simply want not to hear the computer operating, then you can do just a few steps that will help almost completely absorb the noise.- Change the cooling system. Only a radical change in cooling, namely replacing it with liquid cooling, will help get rid of noise once and for all. Thus, it is not fans that will cool the computer components, but liquids, using pumps, heat sinks, radiators, hoses, sensors and similar devices. The difference will be quite noticeable, but such a system costs about 500 (and sometimes more) US dollars. Too expensive!
- Change the system unit box. Sometimes it is enough to change the system unit box to reduce the noise level. For example, you can choose a box with noise and vibration insulation (or even make one yourself). Also think about the legs on which the system unit stands; they should be soft and absorb vibration well, i.e. rubberized.
- Change coolers. The most optimal option for reducing noise (low-cost and noticeable by ear) is to replace all old coolers with new, more modern and silent ones. However, you can’t waste time on trifles, otherwise you won’t feel the effect as such! Some can even be customized by choosing either a quiet rotation mode or a loud, but more powerful one (it is needed for those cases when the PC will be used for a long time without interruptions).
- Carry out regular. If you regularly read our magazine, then in almost every article we mention cleaning your computer, since it is really very important and useful for the system unit, so do not miss this point from our recommendations. After all, regular reading will save you from unnecessary problems associated with noise coming from the system unit.
Now you know about all the causes of noise from the system unit, as well as how to get rid of it.
You've probably noticed that some laptops are quiet, while others start making strange noises from time to time - The laptop is very noisy when working, as if it is difficult for him to cope with the assigned tasks. The hum and noise is especially obvious when loading and launching programs, opening new windows in the browser, or launching applications. Many gamers often complain about buzzing and freezing while playing their favorite games, movie buffs can’t calmly watch movies, and Internet surfers have to wait a long time for the page to load.
This noise and hum do not appear immediately. You may not even notice it at first - the noise becomes louder gradually over time. And if at first your laptop works silently, then after a year or two of intensive use it becomes almost impossible to fall asleep next to you - The laptop is making a loud noise. Such a hum is especially disturbing if it is associated with periodic freezes, or even shutdowns of the laptop. But even if there are no other symptoms of a malfunction, these noises can indicate a number of problems associated with the operation of the laptop. It's time to contact a service center for a routine inspection and cleaning of the laptop from dust.
If your The laptop makes a lot of noise and freezes, It can be assumed that the cooler is overheating. Cleaning it is not difficult, and you should not delay it, since without proper cooling, many vital modules can overheat and fail. The temperature of your device should not exceed the permissible temperature, otherwise the laptop may experience an emergency shutdown or more serious damage. During an emergency shutdown, the screen immediately goes dark, the computer's power turns off, and all unsaved data and files are lost. Therefore, try to do automatic or manual saving of information as often as possible if your laptop shows symptoms of overheating.
Normal performance and quiet, silent operation of the laptop will be restored only after cleaning, which must be done as soon as possible. Be careful if you decide to clean it yourself. In the compact laptop case, all parts fit together very tightly. This means that regular vacuuming is simply pointless. Blowing away dust from many parts will not help - each of them must be cleaned separately. And if your The laptop is making a loud noise Contact an authorized service center for proper cleaning.
The repair technician who will clean your laptop will take it apart down to the smallest parts. Since most of the parts are very small and quite fragile, it will work quite slowly, but quite confidently and clearly. After all, by making just one careless movement, you can end up with a non-working processor with broken needles, damaged cable connectors or torn wires.
To clean a disassembled laptop from dust, you must use professional equipment or technical equipment designed for this purpose. It is necessary to clean not only the external surfaces, but also all the gaps between them, as well as connectors and other hard-to-reach places.
After thorough cleaning, the laptop is assembled, started and tested for functionality. Diagnostics and testing of all equipment entering the service center is a prerequisite for completing the work. Therefore, rest assured that at the Pravsha service center your laptop will not only be cleaned, but also diagnosed.
A laptop can freeze for many reasons. Sometimes troubleshooting is quite a difficult task, but if you do not find and fix the problem, the computer will freeze regularly, preventing you from using the device normally.
Common Causes
Before answering the question: “The laptop keeps freezing. What to do?" it is necessary to establish the reason causing this behavior. In most cases, the user can cope with the initial diagnosis independently.
All reasons leading to freezing can be divided into two groups:
- software arising due to software errors or viruses;
- hardware related to malfunction or problems with computer components.
You can solve a software problem at home. If the laptop freezes due to hardware failure, then in most cases you will have to resort to the services of specialized service centers.
The most common problems that can cause a laptop to freeze:
- viruses;
- program crash;
- insufficient free space;
- CPU overheating;
- problems with components;
- errors during antivirus operation;
- a large number of programs in startup.
Let's take a closer look at the main reasons. This will help diagnose the problem and allow you to quickly solve the problem.
Presence of malware
A variety of malware can damage or destroy important information on your hard drive. In addition, they often make changes that interfere with normal operation of the operating system. As a result, the laptop may start to slow down or freeze completely.
Users who actively use the Internet mostly suffer from malware. You can also pick up malicious programs from any media: USB flash drives, disks, and others.
You can avoid trouble with viruses by installing and updating specialized antivirus programs on time. In situations where the PC has already started to freeze, you can check for malware infection using specialized utilities from security system manufacturers.

CPU overheating
The laptop is a fairly compact device and all its components are located close to each other. Modern high-performance processors generate a large amount of heat during operation. Naturally, manufacturers try to provide sufficient cooling. However, it is not uncommon for the CPU to overheat.
Let's look at the main reasons why overheating occurs:
Dust accumulates quickly inside the case of a modern mobile PC and must be removed using a can of compressed air. Cooling system failure is less common and requires replacement. Cleaning of dirt can be done at home, but to replace the fan, radiator, etc., it is recommended to contact a service center.
Problems with RAM
Incorrect operation of RAM modules can also lead to PC freezing or other malfunctions. As a rule, defects in this component appear fairly quickly after installation. When looking for reasons why your computer is not working correctly, it is recommended to run a special utility, for example, MemTest, and run a test.
If problems are detected with the RAM module, it will need to be replaced with a new one. The user can perform this operation independently or at a service center. During the warranty period, it is recommended to contact the place of purchase without trying to solve the problem yourself.
The system disk volume has decreased
During their operation, the operating system and programs create many temporary files that reduce free space on the system disk. When there is no unallocated space left, applications begin to slow down.
Solving this problem is quite simple by deleting unnecessary programs and data, as well as temporary files. This can be done using the Windows operating system or using special utilities, such as CCleaner.
Programs crash
The software may contain errors, and users often set invalid parameters in the application configuration. These reasons can lead to the laptop starting to freeze at the most inopportune moments.
Usually, when problems arise with the software, you will see a corresponding message on the screen.
To restore operation, you will have to boot Windows in Safe Mode and reinstall or remove the problematic application.
- The most common problems arise from the following software:
- drivers;
- applications to increase computer performance.
Antivirus operation
Modern antiviruses consume significant computer resources. By themselves, they extremely rarely cause the computer to freeze, but they can have a significant impact on performance.
However, when, after installing the antivirus, the computer begins to freeze, you need to reboot into “Safe Mode” and disable or remove it. Then you need to check the compatibility of the program versions and the operating system, reinstall and configure it in accordance with the documentation.
The problem should be resolved, but if this does not happen, then it is recommended to check for viruses on your computer and disable unnecessary programs in startup. As a last resort, you should contact the developer's technical support.
Device problems
Problems with components can lead to the most unpredictable consequences. The computer may begin to freeze during startup, games, or other applications.
The main problems that cause a laptop to freeze are most often associated with the following components:
Diagnosing the problem yourself is usually quite difficult. It is recommended to check the temperature of the processor and video card, test the hard drive and RAM for errors. This can be done using specialized utilities. Some information, for example, the temperature of the central processor can be found in the BIOS.
Many programs in Startup
A large number of applications running alongside Windows can also cause your computer to slow down or freeze completely. Often, users do not pay attention to the settings of the installation program, as a result of which completely unnecessary software ends up in autorun.
You can solve the problem by changing application settings, using specialized utilities, or simply removing unnecessary programs. After changing the settings, you will need to reboot.
In cases where the amount of RAM is small, it is worth considering upgrading. You can increase RAM by replacing modules or, if there are free slots, by simply adding them.
What to do to keep your laptop from freezing
Prevention helps to effectively combat most problems that lead to reduced system performance. In addition, it helps to avoid unnecessary expenses for laptop repair and maintenance at a service center.
Basic preventive measures to maintain system performance:
- dust removal;
- removing unnecessary applications;
- regularly cleaning directories with temporary files;
- disabling unnecessary autorun elements.
Cleaning your laptop from dust and checking the cooling system will not only avoid performance degradation, but also extend the life of your computer. In some cases, due to overheating, components fail and the system simply does not turn on. Cleaning should be done every few weeks.
Removing unnecessary applications and temporary files allows you to free up free space on your hard drive and thereby improve system performance.
Disabling unnecessary startup items will free up space in RAM and improve performance. You can perform these actions regularly using special utilities.

Reboot methods
If any problems occur, the first step is to restart your computer. This allows the system to start from the beginning and possibly avoid errors. A reboot will also be required to launch diagnostic tools, some antivirus utilities, and enter Safe Mode.
- Let's look at the main ways to restart a laptop running Windows:
- program;
mechanical.
Program
The most convenient way to perform a reboot is software. It allows you to avoid accidental data loss and also save all changes made to the Windows configuration. Microsoft, when developing its operating system, provided many ways to manage power and reboot.
- Let's look at the main options for restarting a laptop from Windows:
- via the Start panel;
- using the task manager;
using the command line.
Via the Start panel
The classic reboot method is to select Shut Down from the Start menu. In the window that appears, the user is given several actions to choose from: reboot, shutdown, and put the computer into sleep or hibernation mode.
Via Task Manager
The task manager built into the operating system also allows you to shut down your work.:

Why does my laptop make a lot of noise? “why is the laptop so noisy”, if you purchased a laptop computer in a store, i.e., new, then most likely everything is in order, this is its natural sound, which appears due to the rotation of the fan inside. If your device is more than a year old and has not made noise before, as it does now, it may need to clean the cooling from dust, more on this below, because noise is an indirect sign of overheating, which in turn can lead to failure.
If your laptop hums more than others, it is important to know that the noise of the cooler depends on the size and shape of the blades, the power of the laptop and the location of the cooling system inside the case, in other words, 2 mobile devices that are identical in appearance can make different noises, depending on the power (the more powerful it is, the more heat is generated, and the fan needs to spin harder).
If the noise appears after 1-2 years, but it was not there before, this is already a reason to think about it. When, when loading the operating system, while watching movies, launching games and other programs, the fan starts to work very loudly, it means, with a 90-95% probability, it’s time to clean the laptop from dust, if this has not happened before. What does dust have to do with it and what else could be besides dust is described in more detail below.
Why is it a bad sign if the fan is running loudly?
If the cooler makes a loud noise, this is a sign that the temperature inside is higher than normal, i.e. cooling does not cope with the cooling function assigned to it, and at high temperatures the service life of components is significantly reduced and can lead to the chip on the motherboard burning out - for example, a video card chip, north or south bridge, replacement of which will be quite expensive. How to recognize whether a laptop is noisy above normal or not is described below.
Why does my laptop make noise?
- The noises that a laptop makes can be divided into 2 groups:
2) Mechanical. In this article we consider only the mechanical one, i.e. everything that will be described below relates to mechanical noise. There is a fan in the mobile computer; it cools the cooling system with a flow of air that is expelled through the cooling radiator from the case. Over time, a large amount of air passes through the radiator, including dust, which settles on the radiator grille, thereby creating an obstacle to the outgoing air flow, at this moment the device tries to keep the temperature the same and the only way out in this case is to increase the rotation speed of the cooler blades, therefore The laptop is making a lot of noise. If your cooler is very noisy, in 95 cases out of 100 regular preventative dust cleaning will help
. It is important to make a disclaimer: under load, the fan of any laptop makes a lot of noise.
How loud is the cooler?
In order to understand how clogged the cooling system is with dust, you need to measure the temperature of the processor and video card using special programs, for example hwmonitor. If in a state of inaction, i.e. when only the operating system is running without additional programs and the processor load (the indicator can be viewed in the task manager) is no more than 50%, the temperature should not exceed 75C; under load, the temperature of any sensor should not exceed 95C. If the laptop is very humming and the temperature values exceed the limits described above, most likely the problem is a clogged cooling system - the solution is to clean the laptop inside, and, without having experience in disassembling such equipment, it is recommended to contact specialists to avoid component breakdowns, repairs which are not cheap. If your laptop is very noisy and the temperatures are below the above limits, this does not mean that the problem is not dust. The fact is that the operating temperatures of different models are different, so only high limits that are applicable to all devices are indicated above. On average, modern models require cleaning once every 1.5 years, so even if the temperatures are normal and the cooler is making a lot of noise, it is recommended to do preventive cleaning.
More signs when the fan is loudly humming due to dust
- 1) The laptop turns off without warning (i.e. no error messages appear, but simply shuts down) under load, i.e. when you start playing a game, watching a movie, chatting on Skype or launching other programs. The device has built-in sensors for measuring the temperature inside and, when the values reach critical values, the device turns off. Disconnection may occur for another reason. If an error message appears on the screen before shutting down, most likely it is not due to dust or overheating.
2) The laptop gets very hot, the body is hot.
3) The cooler is constantly humming, although this has never happened before.
4) The laptop slows down, freezes, works slowly, this is also a protective system against overheating; when the temperature exceeds the norm, performance decreases and freezes appear.
When the laptop slows down, the fan makes a lot of noise and the case gets hot. To more accurately understand whether a laptop computer is slowing down due to dust and whether the cooler is humming more than it should, it is enough to measure the temperature inside, for example using the hwmonitor programs; if the values at the moment of freezing are above 90C, then the problem is that the laptop is noisy, most likely dust, if less than 85C the reason is more software.
Unnatural cooler noise
Lubrication
It’s worth mentioning right away that fans break down extremely rarely (in 90-95% of cases, cleaning the dust and lubricating the cooler helps). Above we discussed moments when there is simply a monotonous (constant) sound.
Below we will consider the case when the noise contains tapping, sounds similar to grinding. Here we can recommend lubricating the cooler, but the likelihood that it will help is 50/50, i.e. in half the cases it can help, in the other half of the cases only replacing the fan will help.
27.03.2018 Replacement is 2-3 times more expensive than preventive cleaning, so it is recommended to first clean it, lubricate the cooler if necessary, and if that doesn’t help, then think about replacing it. It also happens that after cleaning the dust, the noise still remains strong, but uniform, in this case, in about half of the cases, lubricant can help.

- Model: Lenovo, B575. The laptop has been buzzing for over 1 year. Very loud. I don’t know what’s wrong, because... I don't understand.
- Hello, first of all, take it to the Service to clean it from dust.
If the laptop begins to make a lot of noise and freezes all the time, the most likely reason is that the cooling system of the device is contaminated with dust. In this case, it does not fully cope with its task - the cooler is forced to constantly rotate at maximum speed. If it also cracks during operation, this may be a consequence of the lubricant drying out. We will tell you further about what else can cause a laptop to make noise like a vacuum cleaner and what to do to eliminate these problems.
Problems with dust and dried grease
The cause of excessive fan noise, if it becomes loud and constantly crackles, buzzes or freezes, is the deposition of dust or some kind of solid particles on the fan blades. Another common reason is the drying out of the lubricant on the axis of its blades.
To resolve this problem you need to do the following:
- Disassemble the laptop (how to do this will be discussed below);
- Wipe the fan blades and axis with alcohol;
- Apply a thin layer of some kind of lubricant, for example, graphite, to the axle;
- Reassemble the device in reverse order.
After this, you will probably feel that nothing in the laptop is buzzing much anymore, and in general it has become noticeably quieter and does not freeze. If the device is new, purchased less than six months ago, then the problem described is most likely caused by other factors, for example, improper use of the laptop.
Noise due to improper use of the laptop
Sometimes users wonder why the laptop is noisy straight from the store. The reason may be due to improper use. It will overheat if you place it on a pillow or sofa while working. The laptop must be placed on a hard, level surface. This is due to the fact that on the back panel in most models, manufacturers like to make additional ventilation grilles, access to which also cannot be blocked.
Note that the noise of a laptop fan during games or when performing other resource-intensive processes is quite normal. Under high load, the processor inevitably gets very hot, so the fan is forced to rotate at maximum speed to ensure normal heat dissipation. In this case, no measures can be taken to reduce its rotation speed or reduce noise - this threatens the laptop with overheating and failure.
Using outdated software
Sometimes the problem of fan noise lies in outdated software, for example, the video card driver or the BIOS itself. For some device models, the BIOS is configured in such a way that when the processor temperature is above 45 degrees, the fan turns on at full power. Since the processor temperature practically never drops below this threshold, the laptop is constantly making quite a lot of noise.
This problem was previously noticed, for example, on Toshiba laptops. But after the release of the updated BIOS with a new logic for the operation of fans, users were able to notice that their laptop no longer hummed and became noticeably quieter. Perhaps the new BIOS will help solve your problem, but first you need to monitor using specialized software (Core Temp or similar) whether the cooler is really “threshing” in vain at a relatively low processor temperature. Only after this can you make an update.
Procedure for cleaning a laptop
To properly and safely clean your laptop, after which it will stop making a lot of noise, you need to sequentially do the following:
- Disassemble the laptop;
- Remove dust and other debris from all internal surfaces;
- Apply a new layer of thermal paste to the processor;
- Assemble the device.
Your laptop should be cleaned at least once a year. This should be done if noise appears even with a small load, or, for example, when the fan is already crackling like a tractor. Often this sound is accompanied by overheating of the processor, which can cause the laptop to slow down and freeze. This phenomenon has an extremely negative impact on the reliability of the device - overheating often leads to premature failure of various computer components.
We disassemble the laptop and clean it
If the cause of overheating is dust accumulated on the internal surfaces and radiator of the laptop, then the device will first need to be disassembled. For the vast majority of laptop models on the Internet, detailed disassembly instructions are provided. Nevertheless, we will give an approximate procedure, since in general they are all similar for different models:
Next, all that remains is to assemble the laptop in reverse order. Remember that disassembling a new laptop automatically voids its warranty. Therefore, if the fan on a new device begins to hum like a vacuum cleaner, if it crackles and freezes, go to service. Old devices, if properly cleaned and used correctly, will not make noise and will last for several years without breaking or freezing.
Deadly, Windows 7 stops responding to any commands, it’s even impossible to open the task manager? Such problems appear quite rarely. It must be said that a computer is a rather complex system, and its performance depends on a huge number of factors. The article will discuss the main ones. After reading, you will learn to deal with most of the problems that lead to “freezes” on your own.
Viruses
The first answer to the question of why the computer freezes is the simplest and most common. It is quite possible that uninvited guests have settled on your computer and are well camouflaged. Typically, viruses not only threaten the security of the system, but also significantly load computer resources. Sometimes this load leads to
Everyone knows how to deal with such a scourge. It’s enough just to install any anti-virus program, update its databases to the latest ones and run the full one. It didn’t help - call and check the processes to see if there are any suspicious ones. It would also be a good idea to look into startup by entering the name of the utility “msconfig” in the “Run” window.
However, if the computer freezes tightly after turning on, it will not be possible to install new software, much less check the PC. In this case, use any antivirus distribution that can create a bootable USB flash drive or CD.
Overheat
When releasing each new device model, manufacturers try to make it more sophisticated than the previous one. And this requires more power. The latter, in turn. increases heat generation. For some time, the standard cooling system copes with its job, but after a while its effectiveness decreases - as a result, the computer freezes completely. What to do if such a disaster happens?
Dust, which cannot be removed, clogs into radiators and interferes with air circulation. As dust settles on the cooler, it slows down the rotation speed of the propeller. Previously, such problems led to device failure. Today, fortunately, computers have become smarter; there will be no endless or video card. Modern devices have the ability to communicate with the motherboard, entrusting it with temperature control responsibilities. As soon as the values reach a critical point, the controller first tries to unscrew the cooler screw, but if this does not help, the system slows down the device, reducing the voltage. Soon the computer freezes completely.
To prevent such troubles from happening, remember a few simple rules:
Very often, because of this problem, the computer freezes in games or other graphic applications. To check how hot your computer components are, you can download a program. Fortunately, there are a huge number of similar ones on the Internet.
RAM problems
RAM is the most important element of a computer, which has a very large impact on its performance. Normal operation of RAM depends on compatibility with the motherboard, BIOS, and other installed memory sticks. A minor glitch, the smallest manufacturing defect - and the computer freezes tightly when turned on, not wanting to work even at low performance.
If you are going to increase or change the RAM, fully study its characteristics, go to the website of its manufacturer and the motherboard manufacturer in advance, study what speeds are supported, what tests have been carried out and whether it is recommended to use the devices together.
If the computer freezes until the configuration is changed, you can check whether the RAM is faulty using Windows 7. Just click on the “Start” button and type “memory checker” in the search column. During the procedure, the program will display all errors if any were found. There is only one recommendation: if there are errors, change the memory.
HDD instability
A hard drive is a device on which absolutely all data (both user and system) is stored. Accordingly, Windows accesses it all the time, reading and writing does not stop for a minute. This means that system performance directly depends on the speed of this component. Over time, “broken” clusters and unreadable areas may appear on it, which will lead to system failures. Often, because of this problem, the computer freezes on the Internet, because while surfing the browser constantly records and deletes many small files.
Repairing a broken HDD
If the HDD is worn out, you need to check it with special software tools that will find all damaged sectors and mark them as non-working. The OS will stop using “bads” and stop freezing. To check, launch the command line by entering the name of the program in the “Run” window - “cmd”. In it, run the command “chkdsk [drive letter]: /f /r” for each partition.
Experienced users can determine the status of the HDD by the sound of its operation. If it starts clicking or whistling, the equipment is most likely faulty and needs to be replaced. Be careful, often, if a hard drive begins to “crumble”, it will soon fail, and it is very difficult to recover data from such a device. Also, if the computer freezes tightly after turning on, there is a high probability of wear on the hard drive.
Incorrect BIOS setting
If the computer freezes after turning on, very often the reason for this behavior of the system is incorrect BIOS settings. Someone may think that an ordinary user should not even try to fix something, but should contact a professional. But still, the computer freezes tightly - what to do if there is no way to call a specialist?
If you approach BIOS configuration with care, even a beginner can handle this procedure. Learn complete information about your computer, and especially about the motherboard. Usually such data is easily found on the manufacturer’s official website. Find out which parameters are most important and what they are responsible for. When using the BIOS setup utility, never change many settings at once. First change a few, reboot, check the computer. Only then continue editing. A special mention should be made of the item that is in every BIOS - “Load Fail-Safe Defaults”. It brings all parameters to optimal - in the opinion of the developer.
Sometimes you can download and install a new BIOS version on the motherboard manufacturer's website. Never refuse such a procedure. Updates often fix critical bugs and improve stability. It is likely that after installing the new version, the freezes will disappear. The main thing is to read the instructions in advance.
Windows Services
The operating system runs a large number of services all the time, either enabled by default or added during operation. The system can work fine without most of them. If some service does not respond or takes up too much processor time, the computer freezes.
To see which of them are in the system and which are running, open the administration window ("Start" - "Control Panel" - "Administrative Tools") and double-click the "Services" shortcut. To get comprehensive information about a particular service, double-click on its name.
First of all, pay attention to those that start automatically. The loading method is indicated in the “Startup type” column. There is only one editing rule - if you do not understand the description, do not disable the component, but find out more about its operation from the Internet. Try to check the stability of the system after each individual manipulation.
Processes and programs
Each program starts its own process (sometimes even more than one), if it enters an endless loop or malfunctions, and the computer does not always freeze completely; Windows 7 still tries to independently cut off oxygen to non-responsive components. It is very easy to identify a frozen element - it usually takes up the lion's share of RAM and almost all the processor time.
Solving the problem using the task manager
You can view the list of running processes in the task manager window. Press the combination “CTRL+ALT+DEL” on your keyboard. If you are sure that some program does not carry a payload, but at the same time takes up 90-100% of the processor time, feel free to terminate it (by pressing “DEL” on the keyboard or by calling the context menu). You can also go to the location where the program is stored from here. This will be useful if you do not understand exactly what you are interrupting.
Checking processes is not always the best solution, but this procedure can often help if the computer periodically freezes. Remember that some programs can load the processor one hundred percent during the most active phases of their work. However, a frozen utility will not stop using maximum resources, and one that performs its functions without failures will again go into passive mode after some time. Also, do not try to end the process called System Idleness. It is used to poll other programs and system resources, and the variable in it does not display the processor load, but just the remaining free power.
