When you turn on the computer, the system boot slows down. The computer is slowing down, what should I do? How to get rid of overheating processor on your computer

Instructions

We will perform Disk Cleanup and clear the system of “garbage”. We launch the standard cleaning program.
For Windows 7: "Start -> All Programs -> Accessories -> System Tools -> Disk Cleanup" (right click ->
For Windows XP: "Start -> All Programs -> Accessories -> System Tools -> Disk Cleanup"
If your computer has several hard drives installed (or one is divided into several logical drives), then a window will appear asking which of these drives to clean. Select the desired system drive on which WINDOWS is installed. (Then it is better to carry out this procedure with all computer disks).
Check the boxes for all the items suggested in the box, click “OK” - and wait. You may have to wait a long time, depending on how dirty the system is

Now let's check the computer's hard drive for errors and failures. First close all running programs and remove all external media (flash drives, hard drives, etc.). For Windows XP and Windows 7, the procedure will be the same.
Open the “My Computer” window in Explorer. Right-click on the system disk or partition of this disk and select “Properties”. In the window that opens, go to the “Service” tab, and there click on the “Run check” button. A small window will open in which you need to check the boxes for the 2 check points presented and click the “Launch” button.
A message will appear stating that Windows cannot check the disk that is currently in use and will prompt you to do so after rebooting. Click "Schedule Check Disk" for Windows 7 and "Yes" for Windows XP. Restart your computer. After the reboot, a scheduled disk scan will begin in text mode. Until it completes, the operating system will not start. The scan will most likely take a long time, so it would be more advisable to run it at a time when the computer is not needed (for example, leave it checked overnight).

The next step will be to defragment the system disk. We launch a standard disk defragmentation program.
For Windows 7: "Start -> All Programs -> Accessories -> System Tools -> Disk Defragmenter" (right click -> "Run as administrator").
For Windows XP: "Start -> All Programs -> Accessories -> System Tools -> Disk Defragmenter"
In the window that opens, select the disk on which the operating system is installed and click on the “Disk Defragmentation” button. (Then it is better to carry out this procedure with all computer disks).

Now let's play around with the size of the paging file.
For Windows XP: "Right click on My Computer -> Properties -> Advanced -> Performance -> Options -> Advanced -> Virtual Memory -> Change."
For Windows 7: "Right click on Computer -> Properties -> Advanced settings -> Performance -> Options -> Advanced -> Virtual memory -> Change."
In the window that opens, select “Specify size” (“Special size” for XP)
Now we multiply the entire amount of your RAM by 1.5 (if there is very little of it, then by 2). We write the resulting value in the "Original size" and "Maximum size" fields.
(And as an exception, if the computer has 4 gigabytes of RAM and Windows XP is installed, then you can set a small value, for example 512 megabytes)

Disable unused services. "Start -> Control Panel -> Administrative Tools -> Services." In this large list of all services, we study the names and descriptions of all services. We decide that all of this can be disabled without harming the state of the system. (Specific advice on the advisability of disabling a particular service can be easily found on the Internet). Stop the selected services (double-click on the selected service “Startup type -> Disabled” and click on the “Stop” button)

Disable unused startup items. First, let's go to "Start -> All Programs -> Startup" and remove all unused shortcuts from there. Then run the standard system startup setup program: “Start -> Run” and write “msconfig” in the line, go to the “Startup” tab and disable all unused programs. (You can easily find specific advice on the advisability of disabling a particular program in startup on the Internet by typing the name of the program into a search engine)

Let's turn off visual effects.
For Windows XP: "Right click on My Computer -> Properties -> Advanced -> Performance -> Options -> Visual Effects."
For Windows 7: "Right click on Computer -> Properties -> Advanced Settings -> Performance -> Options -> Visual Effects."
In the window that opens, switch the item “Ensure the best performance” -> OK

Disable unused devices.
For Windows XP: "Right click on My Computer -> Properties -> Hardware -> Device Manager."
For Windows 7: "Start -> Control Panel -> Hardware and Sound -> Device Manager"
In the window that opens, disable unused devices (right-click on the selected item -> "Disable")
You can disable unused camera, network card, IEEE 1394 controller, COM and LPT ports, etc. If something happens, a disabled device can always be “used” if needed

We clean your computer from viruses using an antivirus with up-to-date antivirus databases. You can use both permanently installed anti-virus programs and free “one-time” ones for routine scanning, such as CureIT from Dr. Web,

After using a Windows-based desktop computer or laptop for a long time, users may encounter a situation where the PC becomes very slow and runs slowly. There can be many reasons for a PC to slow down.

To understand in detail the problem of PC slowdown, we have prepared material in which we will consider in detail the methods and techniques that increase PC performance. By following our recommendations, you can return to its former performance desktop computer or laptop with Windows OS. By restoring the speed of your computer, you can enjoy various multimedia entertainment, computer games and work, while forgetting about the slowdown and various PC glitches.

Cleaning the system in Windows operating systems

The operating systems Windows XP, Vista, 7, 8, 10 have their own built-in system cleaning tools. The main disadvantage of such cleaning products is that they they only clean the trash, which the system itself creates, and even then, not all of it.

To execute complete system cleaning from garbage, where the OS and many programs will be cleaned, you need to use third-party software. One of the best cleaning programs is CCleaner. This utility is produced by Piriform LTD.

The utility is free and downloadable CCleaner on PC from the official website www.piriform.com. The utility has been in use for several years first in the ranking from such well-known online publications as The Guardian, PC World, CHIP Online and many others. The utility works on Windows XP, Vista, 7, 8, 10 operating systems. After installation, we will launch the utility on Windows 7.

To clean the system of debris, use the Analysis button located at the bottom of the window.

The image shows how much garbage the system found. This is the Explorer history when the user opens folders or copies folders. This is also the browser history and various garbage created by utilities.

After analysis remove garbage, which the utility found by clicking the Cleanup button.

In this simple way you can increase the performance of the system and its programs. The utility's capabilities don't end there. The program can also delete unnecessary registry branches, which were created by various software. To take advantage of this opportunity we need to open the “ Registry"and, by analogy with the previous example, click the Search for problems button.

After the search, click the Fix button and thereby delete unnecessary registry entries.

The functionality of the utility is not limited to this, but its coverage does not fit into the topic of the article, so we will move on. Having finished cleaning the system and registry, it’s time to take on defragmentation, which we will discuss in the following examples.

Defragmentation in Windows operating systems

The operating systems Windows XP, Vista, as well as the newer Windows 7, 8, 10, have their own built-in tools that allow defragmentation. The only disadvantage of the built-in defragmenter in Windows XP, Vista, 7, 8, 10 is its operating speed and weak functionality.

Therefore, it is better to use a defragmenter from third-party developers. The best defragmenter today is a free utility Defraggler. utility Defraggler developed by the same company as CCleaner Piriform LTD. Download Defraggler to the PC folder you can also from its official website www.piriform.com, like CCleaner.

Installing Defraggler is quite simple and comes down to a couple of clicks, so any PC user can handle it. Except Defraggler, there are many more high-quality defragmenters, but our choice fell on this one, as it will help us solve another problem due to which your PC can be very slow and slow.

Defraggler works with all current Windows operating systems from XP to Windows 10. Therefore, feel free to install and run it on any Windows. In our case, we ran Defraggler on Windows 7.

To start defragmentation, click the Defragmentation button at the bottom of the window. Next to this button there is a button that can start analyzing the disk for the need for defragmentation. After defragmentation starts, you can monitor it on the disk map.

This process can take a long time and depends on the disk size and the degree of disk fragmentation.

Utility Defraggler can defragment both the entire disk and individual folders and files. Its functionality does not end there. The utility can also:

• Do a quick defragmentation;
• Make the program work according to schedule;
• Defragment free disk space;
• Turn off the PC after defragmentation;
• Defragment the registry.

Of all the functions described, the last one is the most significant. Using registry defragmentation, you can also increase the performance of your desktop computer or laptop. To use this function, go to the menu " Settings» and activate defragmentation of the registry when starting the PC, as shown in the image.

By enabling this option, in your PC at system startup Defraggler will defragment the registry:

Now let's talk about the program's capabilities that we mentioned earlier. Defraggler can view the status of your hard drive, namely S.M.A.R.T..

S.M.A.R.T. is a built-in routine that can determine the status of the hard drive. Let's go to the " State».

The image above shows the parameters of a good hard drive. The following image shows a hard drive with bad sectors:

If this is exactly the situation you have, then the culprit in braking the system is Winchester. Based on this, The hard drive should be replaced with a new one. In addition, the hard drive will not last long in this condition, and you may unexpectedly lose a lot of important information. Probably all of it.

From the example it is clear that using Defraggler you can do:

• Disk defragmentation is long or fast;
• Registry defragmentation;
• Check the condition of the hard drive.

It is also worth noting that if you have an SDD disk type installed in your PC, then do not defragment it, as this may shorten its lifespan.

Solving RAM problems

Very often the culprit behind the PC slowing down and freezing is RAM. Operating systems from Windows 7 to Windows 10 have built-in memory checkers. For example, let’s run a tool to check the RAM for errors in Windows 10. To do this, use the search in the top ten and enter the phrase “ Memory Checker».

Now let's run the found utility.

In the window that opens, select the first item, after which the computer will reboot and RAM diagnostics will begin.

After a long check, the computer will boot and the user will be given the result of the check. If the test result is negative, this means that the RAM needs to be replaced with a new one.

Older operating systems such as Windows XP do not have a built-in memory check. It follows from this that on Windows XP, to check memory, you should use third party software. One of the most popular utilities can check your RAM Memtest86.

Speeding up with ReadyBoost

Sometimes even all the steps taken to eliminate slowdowns and glitches in the PC do not help properly. This happens because your PC weak hardware. To solve this problem in OS, starting with Windows 7 and ending with Windows 10, the user has the opportunity to use technology ReadyBoost.

The essence of the technology ReadyBoost is to use fast USB drives for data caching. That is, using ReadyBoost, you can replace the default swap file on a screw, on a fast USB flash drive.

For example, we will use a PC with Windows 10 OS and a flash drive with the interface USB 3.0. You ask why exactly USB 3.0. The answer is simple, this interface very fast and is most suitable for our task. Let's insert the flash drive into the PC and go to it properties to the tab " ReadyBoost».

Now select the item in the window to speed up our system as shown in the image above and click the Apply button. The setup is done in the same way in Windows 7 and 8.

After these actions, the system should noticeably speed up, long startup times and slowdowns should disappear.

If you want to use the described technology on Windows XP, then use a third party program eBoostr.

Other ways to speed up a desktop computer or laptop and remove the brakes

If the examples discussed above did not help, then the following methods will help solve the problem with brakes and glitches:

• Changing the antivirus program;
• Disable visual effects;
• Stopping unnecessary services;
• Reinstalling the operating system;
• Updating seven to ten.

If you have a good anti-virus program installed on your desktop computer or laptop, then on a modern PC you are reliably protected and this does not affect the performance of the system. But if you have a weak laptop or desktop computer, then it will be noticeable how the antivirus began to slow down the system greatly.

To correct this situation, Panda Security SL has developed an antivirus Panda Cloud Antivirus, which practically does not waste system resources on a weak PC. The secret of this antivirus is that everything complex operations in it are performed in the cloud.

In addition to antivirus, the performance of a weak laptop or desktop computer can be affected by OS visual effects. Since Vista, Windows has used various visual effects that slow down the PC. To disable visual effects, for example, in Windows 10, you need to go to system properties. To do this in the program Execute Let’s type the command “sysdm.cpl”.

Going to system properties, open the tab “ Additionally" In the performance text block, click on the Options button.

A window should open before us where we can disable and enable visual effects in Windows 10.

Visual effects are configured in the same way in Windows 7 and 8. If we talk about Windows XP, then it makes no sense to disable its visual effects, since they already consume few resources.

You need to be careful when disabling services, as this may lead to incorrect operation of the operating system. To stop unnecessary services, for example, in Windows 7, you need to go to the snap-in responsible for services. To do this in the program Execute Let's type the command “services.msc”. After execution, the snap-in “ Services».

In this snap-in you can disable any service. Before disabling an unnecessary service, make sure that disabling this service is absolutely safe for the system. For example, you can stop the service " Print Manager"if your PC is not using a printer.

Another way is complete system reinstallation. After reinstalling Windows, you will immediately notice how fast your laptop or all-in-one PC works. This happens because the OS is new and has a clean registry and no garbage. In many cases, reinstalling the OS helps revive a laptop or desktop PC and get rid of the brakes.

In addition to reinstallation, there are times when a 7 user upgrades the system to Windows 7 and after that it works slowly. The slow operation of the system is due to the way updates are distributed and to the hardware. In the first case, the slow performance is due to a new type of update delivery in the P2P network. That is, updates come from user to user. In the second case, slow operation is associated with old hardware. In this case, only updating components or buying a new laptop will help.

Let's sum it up

We hope that all the material presented in the article will help our readers and you will not have any questions about why the PC began to slow down or why the laptop or all-in-one computer began to freeze. I would also like to give a couple of tips to our readers.

If you continue to experience slowdowns and freezes in your system, then malware may be the culprit of your problem. In this case, you should perform a full system scan for viruses and remove them from the found folder.

In addition, if you own a PC with Windows XP, then it’s time for you to think about changing the OS to a more secure one. XP support has ended long ago and new antiviruses have not supported it for a long time. This means that the system is very unsafe and if you give such a system access to the Internet, you may encounter real problems due to viruses. Due to viruses, you may encounter system slowdowns, as well as theft and damage of personal information.

Video on the topic

One of the most common problems encountered on the Windows 7 operating system is that a computer or laptop “stumbles” or “slows down”. This manifests itself in the fact that the device begins to load much more slowly, respond to user actions, and ultimately slows down and refuses to work. There are a huge number of reasons for such freezing. They can be divided into two main blocks:

In each individual case, different actions must be taken. Let's look at the most common problems with slow Windows, as well as ways to solve them.

Lack of free space

For a computer or laptop to run quickly, the system requires sufficient memory. Most often, Windows is installed on the “C” drive. Due to inexperience, users install all other programs on it (sometimes even in system folders, like “program files” or “system 32”). Make sure that the disk on which you installed Windows has sufficient disk space for comfortable work.

Remove all unnecessary files and programs that are located on the system disk. Typically this includes the following directories:

• Desktop;
• Downloads;
• My documents (library, images);
• Trash files.

By the way, it is recommended to clean the desktop first. The presence of a huge number of different files, shortcuts, folders on it reduces the performance of a computer or laptop several times. By freeing up enough free space (so that the disk bar appears in blue rather than red), the computer will lag noticeably less.

Damage to system files

The next reason that a computer or laptop is very slow may be damage or the absence of files and folders important for the operation of the system. The reasons may be different:

1. Initially incorrectly installed Windows 7.
2. Critical errors after using installed Windows for a long time.
3. Consequences of system infection with malicious files.
4. Incorrect operation of a computer or laptop.
5. Accidental deletion of important system files.
6. Incorrect removal of third-party applications.
7. Consequences of incorrect operation of the registry.

The easiest way to fix the above problems is to perform a system restore. The advantage of this function is that the procedure does not affect programs that the user himself installed on the computer (drivers and other software) or other personal files, but only checks the integrity of the system. If necessary, missing files are downloaded and the computer slows down less. Carrying out this procedure cannot have a negative impact, and after restoration the computer will only work faster.

If the damage is too serious, you have carried out the restoration, but the computer or laptop is still slow or slow, then you can think about the option of reinstalling Windows. This should only be done as a last resort.

Garbage in the registry and startup

As you use your laptop or computer (installing and uninstalling programs, copying files, connecting USB devices, etc.), many entries accumulate in the Windows system registry (). Some are duplicated, others are entered there by mistake. All this leads to system errors appearing, applications conflicting with each other, and the computer slows down and works slowly. To improve the performance of your computer or laptop, it is recommended to clean the registry. Of course, you don't have to do this manually. It is best to use the free CCleaner utility. In it you can not only fix registry errors, but also configure startup settings.

Many programs that are installed on a computer are loaded when the system starts. Sometimes these can be completely unnecessary applications that the user rarely uses, but when launched and working offline, they consume system resources. By removing unnecessary programs from Windows startup, your computer will not only boot faster at startup, but also run faster.

Virus infection

As a rule, the virus operates in stealth mode and requires a lot of system resources, which is why the computer slows down. The following symptoms may indicate that a computer or laptop is infected with viruses:

• the device freezes when performing certain actions (for example, opening “my computer”, the explorer takes a long time to update);
• files and folders are not deleted; on the contrary, they are missing or cannot be opened;
• critical errors began to appear;
• the browser's home page and default search engine have changed, third-party extensions or intrusive advertising have been added;
• third-party programs have appeared that cannot be removed;
• the processor is loaded at 100% with closed programs;
• It is impossible to perform a system restore, start the task manager, or terminate one of the processes.

The problem of virus infection is complicated by the fact that they have a high priority. This means that if the system has a choice: to perform an action requested by the user or a virus, priority will be given to the virus. This results in a noticeable delay when running applications, and the computer slows down. To solve the problem, you need to do the following:

• install an antivirus if you don’t already have one;
• scan your computer for infected files;
• send found files to quarantine or delete.

The virus blocks the launch or installation of an antivirus program

Sometimes infected files change system settings. This results in the inability to run or install the antivirus. In this case, you need to do the following:

1. Use the express check program. Such software does not require installation and is completely free;
2. Perform a system restore. If this is also blocked by a virus, then reinstalling Windows (via a bootable USB flash drive or disk) will help save the computer;
3. Before doing a full reset of Windows, do not forget to save important information to another flash drive (it should be empty), and then scan it on another device for viruses (if the files are infected).

As a rule, an express virus test gives a positive result and takes no more than 30 minutes. After such cleaning, your computer or laptop will work much faster.

Hardware failure

If the computer slows down a lot or starts to freeze completely for a certain time, while making strange sounds (knocking, creaking, noise), then this may indicate a serious internal breakdown and hardware malfunction. There are a number of problems that affect the speed of a computer, and some of them can be easily identified by the average user:

• hard drive failure;
• CPU overheating due to cooling system failure;
• cooler failure;
• presence of dust in the system unit or laptop.

Hard drive failure

The speed of a computer or laptop depends more than 70% on the hard drive. Unfortunately, the hard one does not last forever and tends to wear out. When this moment comes, some slowdowns are noticeable in the system. This is due to the fact that the hard drive consists of sectors on which information is stored. From time to time they are erased and marked by the system as “broken”.

When a computer reads information and enters a “broken” sector, the system crashes (a characteristic sound may appear), the computer freezes until it moves to another sector. Such a freeze can lead to a critical error and a system reboot. The more “bad” sectors there are, the more often the computer slows down and the closer the time is when the hard drive will have to be completely replaced. This problem is inevitable, but it can be delayed as much as possible and the consequences reduced. To do this you need to do the following:

1. Defragment at least once a month. Full instructions.
2. When cleaning your computer from dust, do not forget about the hard part; heating has a negative effect on it.
3. Avoid physical impact on the hard drive from the outside.

If you suspect that one of the sectors is “broken,” use special utilities to find and restore them.

We look for bad (marked in red) sectors on the hard drive using the “Hd Tune Pro” utility

Overheat

Another common reason for a slow computer is overheating of computer components. It is quite easy to diagnose such a malfunction using the following signs:

• The computer boots quickly and works for a while, then performance drops sharply.
• The cooler makes a lot of noise or is not audible at all.
• The computer turns off unexpectedly.
• If you have a laptop, you can simply put your hand on it and check the temperature by touch (there have been cases when the computer overheated so much that you could get burned!).

If the reason for slow operation is overheating, then you need to do the following:

• Determine which component is overheating (processor, chipset, hard drive). This can be done using any free utility or even gadgets for the Windows 7 desktop.
• Clean the system unit or laptop from dust and, if necessary, change the thermal paste.

This procedure will not only increase the speed of your device, but will also extend its life.

Prevention

The computer cannot start to slow down unexpectedly (except for physical impact on it, after which this can actually happen). Any problem begins gradually. To ensure that the device does not bother you with malfunctions for as long as possible, you need to do a number of procedures that will help improve productivity:

• Monitor the amount of free memory.
• Sort installed programs and uninstall them correctly.
• Check the registry for errors.
• Do defragmentation.
• Clean your computer from dust.
• Remove unnecessary junk from your desktop in a timely manner, empty the trash can, etc.
• Watch autoloading.
• Scan your system for viruses.

All this does not require a lot of time or special knowledge, but it will save you a lot of nerves in the future.

We are absolutely sure that every user has encountered such a problem as a slow PC. And it seems like just “yesterday” your favorite computer was simply “flying”, but today it is completely unclear why the computer is slowing down and what to do next.

It is clear that such a situation will not make anyone happy, but rather, on the contrary, it will make them nervous and angry about it. And it seems quite logical if the computer began to lag and slow down already at an “advanced age,” but what to do if this happens to a new PC? And most importantly, why? You will find answers to these and other questions in our article.

The answer is quite simple. Not all users realize that any new device must be configured and optimized before you start using it.

Similar setup and cleaning of various kinds of “garbage” (adware or unnecessary programs, temporary files, lost registry keys, etc.) should be carried out regularly with an already working computer. Otherwise, you cannot avoid a situation when your computer with Windows 7, XP or 8.1 starts to slow down, and most likely quite badly.

Those who do not want to delve into the reasons, or are simply not confident in their abilities, can contact our urgent computer repair in Moscow. Professional technicians will quickly fix all problems with your PC.

All the many reasons why a computer can lag and slow down can be divided into two types:

• hardware problems
• problems with the software.

These two types are very closely related and very often simultaneously affect the speed of the PC. Let's look at them in order and figure out what to do in each case and how to fix the problem.

• Problems with hardware
• Problems with the software

The computer slows down due to hardware problems

We hope that everyone knows what hardware is. If you don’t know, this is what they call the spare parts or components of the system unit - what it consists of.

Overheating of the processor or other components

Many users often forget, and some do not even know, that they need to monitor the processor temperature. Otherwise, in our practice, situations regularly occur when a client brings the processor temperature almost to the limit, then wonders why the computer slows down when running Windows 7.

In order to maintain normal temperature conditions, you need to regularly look inside your system unit. You can learn more about how to clean the system unit from dust and change thermal paste from our article.

If your computer lags in games or graphics programs, then it would be a good idea to find out if the video card is overheating. It may also need cleaning.

Monitoring the temperature of any components is quite simple: there are many programs and utilities for this purpose. Install any of them on your computer and regularly check the sensor readings. In addition, the processor temperature can be found in the BIOS.

The need for modernization

Even if you don’t play computer games or work with resource-intensive programs, but only use email and social networks, then sooner or later you will still have to think about upgrading your computer or buying a new one. Why? Let's explain.

Every day components become obsolete. New versions of programs (even simple ones like browsers, Skype, ICQ, etc.) are becoming more and more demanding on PC power. Those. yours simply doesn’t have enough resources to complete seemingly simple tasks. As a result, the computer starts to slow down and become terribly dull, and you get nervous and angry.

Increasing the amount of RAM or replacing the processor with a more powerful one will help solve this problem. An alternative option could be to “overclock” the processor, but whether this is possible or not depends on the hardware features of the particular PC.

If games on your computer are slow

Do you like to play modern games? Drive a tank or fire a burst of machine gun fire at the enemy?

We hope you remember to make sure your graphics card is up to par with today's gaming requirements. Otherwise, you will puzzle for a long time why the computer slows down in games at the most crucial moment and you are killed over and over again.

Slow hard drive

Few people realize, but today the most “bottleneck” point in the operation of computer hardware is the hard drive. It's all about the limited spindle speed of the hard drive. In desktop computers it is 7,200 revolutions per minute - and this is one of the reasons why the computer slows down and slows down. There are faster HDDs, but their cost is significantly higher.

In addition to the familiar hard drives with magnetic platters, over the past few years a new type has been gaining popularity and becoming increasingly accessible - the SSD drive. The principle of its operation is not based on magnetic plates, but on recording information using fast flash memory.

Such hard drives are several times faster than conventional HDDs and operate absolutely silently. However, the obvious disadvantages are the high cost with a fairly small volume and a limited number of read/write cycles. To learn how a hard drive works and how it works, read our special article.

Comparison of HDD and SSD speeds

Problems with the software

Of course, in addition to the hardware, the operating system also has a great influence on the speed of operation. In this section, we tried to collect all possible software problems and tell you how to fix them.

Computer viruses

This is probably the most common reason why Windows 7 on a computer very often slows down. And in particularly difficult cases, the PC may completely freeze.

There are quite a few types of viruses that can significantly affect the speed of a PC. In addition to the “unauthorized” use of computer resources, viruses damage system files, which in turn leads to slow operation of the entire PC. In order to avoid this problem, you must install a powerful antivirus on your computer and regularly scan all disks, folders and flash drives for viruses.

If for some reason you still do not have an antivirus installed, then download official trial versions (for a month) on the Kaspersky or Doctor Web website. Or you can download a simpler, but longer-term antivirus: for example, the free version of Avast or AVG.

After downloading, install and run a full scan of your computer. This process is quite lengthy, so plan ahead. It is recommended to remove or quarantine all detected viruses.

A large number of programs in Startup

Almost all software developers and manufacturers want their software to be used as often as possible. And, even if they didn’t use it, they somehow remembered it. Therefore, when installed, most programs are automatically registered in the “Startup” of the operating system. As a result, along with the PC startup, several dozen programs, their modules or agents are turned on. As a rule, we don’t need them or use them extremely rarely.

Such programs consume computer resources (especially RAM), as a result of which your computer becomes very slow and slow. You can avoid this problem by disabling autoloading of unnecessary programs at the time of installation, or in the operating system settings.

If you have Windows 7, then write “msconfig” in the search and run the utility. The “System Configuration” window will open, go to the “Startup” tab and disable everything that is unnecessary. After that, click “Apply” and reboot.

If you have Windows 8 or 10 installed on your computer, then right-click on the “Taskbar” and select “Task Manager” from the menu that appears. A window will open in which we go to the “Startup” tab and similarly disable everything unnecessary.

If you don’t need a program or game at all, you can completely remove it. We also told you how to properly remove programs and games.

Operating system registry clogged

The more time has passed since installing the operating system or purchasing a computer, the more different programs are installed and the more the computer will slow down. Some programs are installed, some are removed, however, deleting a program does not mean that there is no mention of it left on the computer.

As practice shows, some files and registry entries almost always remain. The more such lost registry keys, the slower the PC runs. There are many programs that work automatically to clean the registry.

The most popular and, in our opinion, high-quality program is CCleaner. You can download the latest version for free on the developers' official website.

After installation, launch the program and go to the “Registry” tab. Click "Search for problems and wait for a while." When the program finishes finding errors, click “Fix.” You can save backups or not, as you wish. After a few seconds, the program will finish correcting errors. We recommend repeating the procedure several times.

Despite the fact that the program copes with its task perfectly, in any case, everything must be done carefully, monitoring all changes in the operating system. Even a small error in the registry can lead to the inoperability of the entire OS. And the computer will slow down and lag even more.

If you have already had such a problem, then from our company you can order the reinstallation of Windows of any version on your computer or laptop.

Outdated device drivers

Another reason why your computer can be very slow is outdated drivers. It is recommended to regularly update drivers for each device on your computer. You can find the new driver version on the device manufacturer's website. Often, updating the driver can not only increase the speed of operation, but also make it more stable, eliminate freezes, random reboots and other failures in the PC.

If you have difficulty finding the necessary drivers on the manufacturer’s website, you can use the free DriverPack Solution program. It is an archive of all kinds of drivers with automatic installation. Run the program and it will automatically find drivers that can be updated.

The computer slows down due to file system fragmentation

Not everyone knows that when working with a hard drive, the operating system does not write files to it in order. Typically, large files are split into many small individual pieces. As a result, the next time the file is accessed, the hard disk head is forced to search for each such fragment. This significantly slows down the entire system and ultimately slows down or slows down the computer. What to do in this case?

The defragmentation operation allows you to “collect” all fragments of files and redistribute their location on the hard drive, which increases the speed of your PC. Defragmentation can be done using both the operating system itself and specialized programs.

We tell you how to run defragmentation using Windows 7 or any other version.

Open “My Computer” and right-click on any logical drive and select “Properties”. Go to the “Service” tab and click “Optimize”. In the window that opens, select the desired logical drive and click “Optimize”. This process will be lengthy, so be patient. Once defragmentation is complete, your computer will lag much less.

But we draw your attention to the fact that if you use an SSD disk, then under no circumstances should you defragment it. This will only reduce its lifespan and will not give you any benefit. So look for other reasons why your computer is slow and slow.

In this article, we looked at the main reasons why a computer most often slows down. If you still have not been able to figure out why your computer is not working fast enough, then you can always turn to our computer service Compolife for help. Our company’s specialists will diagnose your equipment and system, quickly and accurately determine the true causes and eliminate all malfunctions.

If you know any other reasons why your PC may slow down and what to do in this situation, write about them in the comments to this article. Thank you!

Call a specialist

If your computer is slow, the first thing to do is open the task manager to check the load on various components. Press the key combination “Ctrl+Shift+ESC”. You can also launch the dispatcher using the taskbar context menu.

Go to the Performance tab and take a look at the first three sections: CPU, Memory, and Disk. The load is indicated as a percentage and is updated every few seconds. Based on these data, a graph is constructed showing the change in load over time. More detailed statistics are available via the “Open Resource Monitor” link at the bottom of the Task Manager window.

If for any parameters the values ​​are constantly close to the maximum, you should consider adding or replacing these system components. For example, the screenshot shows high CPU usage and a small amount of available RAM. The PC slows down even with a small number of applications running simultaneously. This means that it is advisable to install a more powerful processor and add RAM.

Important! You can see exactly which applications are loading your computer on the “Processes” tab.

Dust in the system unit

The reason for the slow operation of the PC may be the abundance of dust in the system unit. The PC may slow down due to overheating, since dust on coolers and surfaces of parts interferes with the normal cooling of system components. It is recommended to clean the system unit regularly. The frequency of such cleaning depends on the number of fans inside the case and the dirtiness of the room in which it is located.

Regular art brushes are best suited for sweeping away dust. You can use a vacuum cleaner to remove its residue. Computer stores also sell compressed air cans equipped with a long tip. They are used to remove dust in hard-to-reach places. The high pressure in such cans provides a rapid, directed air flow that blows dust out of the cracks.

Overheat

You can diagnose system overheating using specialized programs. For example, the free Speccy utility from the developer Piriform. Install and open the application. The General Information tab will show the temperature of various computer components. It is recommended to measure the temperature not immediately after turning on the PC, but after some time of operation. If the temperature is indicated in yellow, its value is within normal limits. Orange and red colors indicate overheating, which is causing the PC to slow down.

Note! To view the dynamics of temperature changes, click on the green icon to the right of the value.

Viruses

The reason why your computer slows down can also be due to the system being infected with viruses. If you do not use an antivirus on a regular basis, use one of the quick PC scan tools. For example, Dr.Web CureIt, Kaspersky Virus Removal Tool or ESET Online Scanner. These programs allow you to check your computer for viruses, and do not require constant background work. Therefore, they do not affect the performance of the PC after the scan is completed.

Run Kaspersky Virus Removal Tool after downloading it (installation of the utility is not required). In the license agreement window, click Accept. The program will take some time to initialize. Click “Change settings” to select objects and directories in which to search for malicious files. After this, run the scan.

Many programs in autorun

When installing some applications, they are added to autorun. In the future, such programs will open automatically every time the operating system boots. This slows down your computer because these applications use system resources. Their list can be viewed in the task manager, section “Startup”. Select unnecessary applications and click "Disable" in the context menu. The next time you boot Windows, the changes will take effect and disabled executables will no longer be launched automatically.

Large number of temporary files

The CCleaner program does a good job of cleaning your PC from unnecessary temporary files. Download and install the application. On the “Cleaning” tab, select the sections in which unnecessary data will be scanned and deleted. Click Analyze to search for temporary data that can be deleted. In this case, you will need to close running browsers. If other programs were checked in the Applications section, they will also need to be stopped.

When the analysis is complete, click the "Clean" button. The removal of temporary files will begin, the excess of which can slow down the PC. Disk cleaning progress will be displayed as a percentage. The process may take several minutes.

Note! Using this utility, you can also clean the Windows registry. To do this, select the “Registry” tab from the available functions on the left side of the window.

Not enough free space on the system disk

When there is little free space left on the local HDD partition (in which Windows is installed), the PC may begin to slow down. You can check the amount of remaining space in the “This PC” section. If the full indicator appears red, there is a need to delete unnecessary files. You can also use the system utility to free up space. To launch it, select “Properties” in the context menu of the system drive, then click “Disk Cleanup”.

After the application evaluates the data available for deletion, you will be asked to choose which of them you want to erase. Check the boxes next to the selected items. In the dialog box, confirm your intention to clean the HDD by clicking the “Delete files” button.

Incorrect performance settings

This reason is most relevant on older computers. If your device is slow, open the “This PC” folder and open the “Properties” option in the menu. Go to the "Advanced" tab. Under Performance, click Settings.

In the Visual Effects section, select the Provide better performance option. After that, click on “Advanced -> Virtual Memory”. Here you can increase the size of the paging file - an area on the hard drive that is used to temporarily save data from RAM. If the computer is slow and this is due to a lack of RAM, the page file can be increased. The system indicates a recommended value for the amount of allocated memory, but you can also set a larger size.

Hard drive problems

Over time, so-called “bad” sectors can form on a computer’s hard drive, which can cause the computer to slow down. You can check the overall performance of the drive and the presence of such sectors using the free Victoria utility. Unpack the program archive, copy the “porttalk.sys” file to the driver directory before the first launch - C:\Windows\System32\Drivers.

Run the program as an administrator, as it requires additional permissions to run it. On the “Standard” tab on the right side of the window, mark the HDD that needs to be checked. Go to the “SMART” section and click “Get SMART”. The application will test the selected computer hard drive.
