Why does the computer slow down and freeze in Windows 7? Other ways to speed up a desktop computer or laptop and remove the brakes

Many users, including me, prefer the good old Windows 7. This instruction is dedicated to them.

Just recently, an acquaintance came to me and said: “My daughter’s Windows crashed, her computer freezes, what should I do? San, I just recently bought her a laptop, and I’ve already taken it to the store for reinstallation three times - two of the rusty ones fell off,” the acquaintance begged.

This “breakdown” of the operating system is also called - crashed windows activation, although what kind of activation we are talking about is unclear. Well, let's figure it out!

Sections of the article:

So, the patient’s symptoms are as follows: Windows 7 began to slow down unusually, wait full load it takes long minutes and minutes... as mentioned above, the computer hangs treacherously - what to do when after windows updates Can't wait for it to load?

Indeed, many people face similar grief (I was once included).

Well, now, without thinking twice, I decided to write an article.

Although it has long seemed that such problems are a thing of the past, observations say otherwise. And since there are those who are in distress, then perhaps my writing will be useful to someone.

Windows 7 setup and maintenance

Herself Windows setup, in general, is simple and obvious. But the question doesn’t sound quite right, because there is no (exceptional) setting at all. There is adjustment for certain user needs.

And it’s a completely different matter when some errors occur or interruptions in the operation of Windows 7.

Let’s dilute our story a little with lyrics so that our current optimization of Windows operation is more clear, and you yourself can understand and eliminate the error in the future:

Probably, many, just like the mentioned comrade, act in a similar way: we bought a laptop, brought it home - we use it.

And then - bang! ...and Windows 7 or some other operating system crashed. And the time has only passed a month or two, but it’s enough - Windows 7 has started to slow down so much that - AWESOME!

What to do?

The user, girding himself, steps on thin ice to the very store where he purchased the computer machine, and says affectionately:

- Install Oska again, man!?

- Hop! Bro, no problem. 900 kopecks, and forward, - here the buyer scratches his back pocket and feels the back of his head... finally decides, “Let it all go to waste...”

They are installing... The workers rattle in the back room for a second and... - Go, dear, break a new one for your health... and don’t forget to come back often, wisest one.

The fact is, guys, that methods of selling goods and services have infinite number methods of a modern shopkeeper and merchant. And the universe can’t keep up...

So the notorious word “quality” is out of the question. For example, I have come across outright garbage assemblies, which are nowhere to the left. And these wonders of the world of Russian merchants bring (here is a brilliant work of balance in paradoxes...) a lot of titey-miti to the seller of the lexicon of happiness, AND A LOT of grief to the ordinary user. My pocket especially itches financially after my wife’s instructions. Once or twice you overpay and go “left” while the woman is sleeping.

In general, this is logical: professional software it costs expensive. And we decide “it was or was…” I’ll buy a hundred rubles for the installation disk...

I'll tell you - the difference in price, technical distinction The OS will be hardly noticeable if the installation and adjustment of Windows, and then the use of the OS, are incorrect.

And if you decide to “sit” on the “left” for some time, then I will tell you how to make sure that the installed “version” of the OS works no worse than the faces, and maybe in some ways faster.

Modern computers have quite high performance. Even the cheapest system unit works an order of magnitude faster than gaming computer ten years ago. Unfortunately, sooner or later any personal computer user is faced with significant system slowdown. Any action takes much longer than it was before. Playing media files, launching applications, and even moving from one directory to another takes an extremely long time.

The most unpleasant thing in this case is that many factors can cause deterioration in PC performance. However, you can identify a number of the most common reasons and find out how to deal with them. So, why does the computer slow down and how to try to fix it.

Perhaps one of the main reasons for the deterioration of computer performance is associated with the entry of malicious software into the operating system. Fortunately, PC virus infection can be easily distinguished from other factors. Once malware gets in, the computer not only slows down, but also the interface slows down, the operating system regularly crashes. The most common signs of viruses entering your computer include:

• Computer freezes for no reason
• Impossible to remove one or the other
• The appearance in all directories of an unidentified file
• Destruction of text and image files
• Encrypting user files
• Ads appearing on the desktop

To clean a PC from viruses, the user will have to sacrifice some data. The fact is that even after installing anti-virus software, not all files will pass quarantine. Most of the data, unfortunately, will be deleted.

One way or another, a person has only one way, install reliable anti-virus software and carry out full check system, agreeing to delete “incurable” files.

To the most reliable antivirus programs can be attributed to: dr. Web, NOD32 and Kaspersky.

What advice can you give to users? Everything is very simple, after Windows installations, the first step is to install an antivirus software, after which the user should only apply from official sites, or in extreme cases from .

Splitting the hard drive into two local disks is certainly useful. In case of any problems with the OS, the user simply reinstalls the system.

But sometimes users allocate an extremely small amount of space for the operating system. As a result, after installing Windows, on “C” (such letter Windows assigns to the system drive by default) there is little left free space, and if you install several large applications such as Photoshop or After Effects, free space There will be even less left.

Over time, on local disk C set accumulates temporary files, game saves, temporary files, unfinished projects and much more.

To clean up garbage, the easiest way is to use CCleaner program, the database of which contains files that can be deleted without consequences for the operating system. In addition, the PC user should regularly delete the history in the browser.

I can give you one more piece of advice. IN Lately more and more people are using the browser Google Chrome. IN this browser there is one convenient feature, namely, the creation of several profiles. Many people get carried away with this feature, creating dozens of profiles, but one profile takes up about 500 megabytes of disk space.

Surely many users are familiar with the situation when the computer works relatively stable, but when starting even the simplest game, the PC begins to make annoying noise, and the processor is loaded at 100%.

Unfortunately, this is a common problem among those users who purchased a ready-made system unit. Many people simply do not know that a computer is not a TV or any other electronic device. The structure of the system unit is designed in such a way that during the day, a huge volume of air passes through its case, and along with it, dust gets onto the parts. Over time, coolers, radiators and the surface of components begin to become covered with a layer of dust.

As a result, the cooling system is unable to properly cope with cooling the computer.

To check the temperature of the power supply, just place your palm on the back case, in some cases, the temperature is such that it is simply impossible to hold your hand.

To check the temperature of other components, you will need third-party software, such as AIDA64.

Normal temperature under load should be something like this:

1. Processor - no more than 60 degrees Celsius
2. Motherboard - within 40 degrees
3. Video card - no more than 70
4. Hard drive - up to 40 degrees

Of course, it all depends on the individual details of each assembly. For example, AMD processors run hotter than Intel processors.

If you don't decide for a long time this problem, computer components begin to wear out quickly, and as a result, the PC will simply fail.

To solve this problem, you need to disassemble the system unit, clean every part from dust (especially) and replace the thermal paste on the processor, video card and motherboard chipset.

Gradual wear of the hard drive

Each part in the system unit has limited period services. However, some components fail earlier than others, for example, the processor rarely fails, while HDD works stably for no more than five years on average.

Term work hard disk most often depends on the quality of manufacture, however, some user actions can significantly extend the service life of the component.

Firstly, as mentioned above, it is necessary to monitor the temperature of the part, and secondly, carry out.

The structure of the hard drive is designed in such a way that the head moves along the surface of the magnetic plate, reading the information scattered on it.

For example, in order to play a video file, the heads move across the entire surface of the hard drive, looking for necessary information, accordingly, over time, the moving mechanisms wear out greatly. Defragmentation is designed to group information about a file in one place, instead of searching for it throughout the entire drive.

Lack of RAM as a reason for computer slowdown

When any application is launched, its data is loaded into, respectively, the more difficult task is put in front of the system, the more RAM will be spent on its execution. Some modern games require at least 16 gigabytes random access memory.

The shortage of RAM is especially acute when working with browsers. The more tabs you have open, the more your RAM is loaded.

There are many solutions to this problem, for example, increasing the size of the paging file, due to which, after the RAM is full, the data will be charged into a specially designated sector on the hard drive, but at the same time, the speed of the computer will invariably decrease.

The only way out of this situation is to purchase additional RAM. Unfortunately, if a buyer is using DDR2 or DDR3 and decides to upgrade new type memory, DDR4, along with RAM, he will have to change the motherboard.

If we compare the system unit with the human body, the processor can be called its heart. Thanks to central processor All calculations are performed on a computer.

A weak processor is unable to play high-definition video, run high-performance games, or convert multimedia files etc.

Many PC users try to increase the frequency of the component, but unfortunately, this can not be done with every processor, and the resulting power, for complex calculations it still won't be enough.

Unfortunately, as with RAM, this part will have to be replaced.

Surely many people are annoyed when, after turning on the computer, previously installed applications, such as Skype, antivirus software or uTorrent, start popping up on the screen.

Not only does it prevent you from getting started quickly, but it also affects the overall performance of the system.

To disable autoloading, in the settings of each program you need to uncheck the “load the program with Windows” option.

You should leave autoloading only in those programs where it is truly important, for example anti-virus software or virtual Alcohol wheels 120%.

Many PC users are not even aware of the existence of the registry, but it is in it that all information about installed applications, registration, system settings, etc.

Over time, the registry becomes filled with garbage left by remote applications, which prevents the system from working as expected.

To solve this problem, you must either have a good understanding of the registry, or use the same CCleaner application, which will automatically remove all unnecessary entries.

The computer slows down when using the browser

Many users complain that the computer slows down when working with . Unfortunately, the problem is rarely in the browser.

And in fact, sometimes it happens Flash crash player, which leads to a RAM leak, but this happens extremely rarely.

The browser itself is very demanding on processor performance, and especially on RAM. In this case, a person must simply replace the outdated components of the system unit. In addition, it would be a good idea to clear your browser cache and browsing history from time to time.

We have looked at the main reasons why your computer slows down. For stable operation systems, regular maintenance is required personal computer, both technical and software. When handled with care computer technology, the computer can last for many years.

Are you familiar with the situation when, after reinstalling the operating system, the computer starts to slow down and freeze? WITH similar problem encounter many users, and they are not always able to establish the reason why such a nuisance, not to mention its elimination. In this article we will talk about why after reinstallationWindows7 computer slows down.

Note: Most of the reasons described below are also relevant for other OS versions.

Outdated hardware

If your computer previously had Windows XP, and now you have installed on it Windows 7 , and your PC is far from fresh, there is a high probability that under the new operating system it will begin to slow down and freeze. Recommended system requirements for these versions, the OS is significantly different, so a computer that worked normally on XP may well not cope with everyday tasks on the “Seven”.

Inappropriate OS bit depth, insufficient RAM

Operating systems, as you know, come in two types: 32 and 64-bit (bit). The OS bit depth itself must match the processor bit depth. That is, if you have 32 bit processor, and you installed 64-bit Windows 7, most likely, the computer simply will not support it, which will lead to constant freezes.

In addition to the processor capacity, at least important role RAM and its quantity also play a role. The recommended amount of RAM for a 32-bit OS is 1 GB, and for a 64-bit OS is 2 GB. It is worth understanding that recommended requirements are minimum acceptable, that is, not the most modern computer with 64 bit processor and 2 GB of RAM (not latest generation), can also brake under control Windows 7 64 bit, as it will pull it “butt-to-tight”.

advice from CompDude : Before reinstalling the operating system, read the recommended system requirements and the “abilities” of your computer.

You can find out the processor bit depth and the amount of RAM installed in your computer by opening context menu V " My computer" and selecting " Properties».

Not correct drivers

Make sure that after reinstalling Windows 7 you have installed the correct drivers for all hardware. If you have discs with native drivers, good, that means you did everything right. If there are no disks, you can use a special driver pack that automatically detects which components are installed on your PC. The program downloads the drivers necessary for your version of the OS and your hardware via the Internet and installs them.

Check your computer components, clean it of dust

We recommend that you look inside the system unit and make sure that all components are correctly connected. Of course, the likelihood that something came off immediately reinstallationWindows small, but still worth checking. You never know, suddenly one of the RAM sticks has moved away, this also happens sometimes.

Once inside the system unit, make sure that all its contents are clean and tidy. If not, put him in that state. If you have not cleaned your PC of dust for a long time, and now it covers the components in layers, of course, this will cause the system to slow down, no matter how productive your computer is.

That's all, now you know why after reinstallationWindows7 computer slows down, and how to fix this problem.

One of the most common problems encountered in operating system Windows 7 - the computer or laptop is “stupid” 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 operation, as well as ways to solve them.

For fast work computer or laptop, 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 comfortable work disk space.

Remove everything extra files, programs that are on 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. Availability on it huge amount various files, shortcuts, folders, 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 wrong 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 malfunction with the registry.

Most easy way To fix the above problems, 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 effect, 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.) in system registry Windows accumulates a lot of records(). Some are duplicated, others are entered there by mistake. All this leads to the appearance system errors, applications conflict 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's best to use the free one 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 it can be completely unnecessary applications, which the user uses quite rarely, but when starting and working in offline mode they consume system resources. removing unnecessary programs from Windows autorun, the computer will not only boot faster at startup, but also run faster.

Virus infection

Typically, the virus works in hidden mode and requires high costs system resources, for this reason 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;
• has changed in the browser Homepage, default search engine, added third party extensions or intrusive advertising;
• appeared third party programs, which cannot be deleted;
• 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 are modified 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 blocked by a virus, then it will help save the computer reinstalling Windows(through bootable USB flash drive or disk,);
3. Before doing the full reset Windows don't 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 check for the presence of viruses gives positive result and takes no more than 30 minutes. After such cleaning, your computer or laptop will work much faster.

Hardware failure

If your computer slows down a lot or starts to freeze completely certain time, while publishing strange noises(knocking, creaking, noise), this may indicate a serious internal breakdown and malfunction of the hardware. 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:

• malfunction hard drive;
• 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 critical error and reboot the system. The more “bad” sectors, the more often the computer slows down and the more time is getting closer, when the hard drive will have to be completely changed. 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 to 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 one common reason slow work computer - overheating of computer components. It is quite easy to diagnose such a malfunction based on 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 worker Windows desktop 7.
• 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 also remove them correctly.
• Check the registry for errors.
• Do defragmentation.
• Clean your computer from dust.
• Delete on time unnecessary trash from the desktop, empty the trash, 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.

In contact with

A severe decrease in performance is one of the most common problems that a computer user sometimes encounters.

There are many reasons that can cause “brakes” in the operation of the system. Fortunately, the user can fix many problems independently and quite easily.

The most common problem is overheating

Computer parts generate quite a lot of heat during operation. To effectively remove it, cooling systems are installed inside the PC. But their work can be disrupted due to dirt and dust, or they themselves can break, then overheating occurs. As a result, the computer begins to “slow down” or even turn off at the most unexpected moment.

Let's look at what signs may indicate overheating of some computer components:

• The PC often freezes, especially when launching games and other resource-intensive applications;
• a sharp decrease in productivity.

Users can fix this problem without the help of specialists, especially if we're talking about about desktop PCs. In this case, to troubleshoot problems, it is enough to clean the PC from dirt and dust.

Here is the procedure for cleaning the system unit:

1. disconnect the power cord;
2. open the block cover;
3. remove dust and dirt;
4. checking the cooling system;
5. if necessary, replace thermal paste;
6. assemble the computer and test its operation.

To clean your desktop PC, you don't need any special tools. It is quite possible to get by with a soft brush and a screwdriver; a vacuum cleaner will not be superfluous, since with its help it is more convenient to remove a large layer of dust.

Laptop users are less fortunate, despite the fact that the cleaning process is approximately the same as for desktop PCs, it is extremely rare to complete it on your own the first time. The first time it is better to use the help of professionals.

Problems due to incorrect update

Many updates are constantly released to the operating system that eliminate bugs found. Usually they are downloaded and installed automatically. In this case, the installation of updates may not proceed correctly for various reasons.

In this case, the following problems may occur:

If the user encounters any of the problems listed above after installing the updates, he needs to perform the following steps:

1. roll back the system to a point when no problems occurred;
2. make sure there is free space on your hard drive;
3. check your internet connection;
4. try installing the update manually from the Microsoft website.

Lack of free space

If your computer starts to slow down, Windows 7 may simply not have enough free space on the system disk. The fact is that when the system and programs operate, many temporary files are created; if there is not enough space to create them, the system begins to slow down. In addition, space may be needed for virtual memory.

You can free up space on your system disk in the following ways:

1. removing unnecessary applications;
2. transferring or erasing large files, such as movies;
3. cleaning temporary files.

The first two ways to increase free space usually do not cause difficulties for users. But when cleaning temporary files, questions arise regularly. Meanwhile, this procedure is also not complicated.

There are two ways to do it:

• using system tools;
• using third party utilities.

Usage special programs for deleting temporary files shows greater efficiency, but requires higher qualifications from the user. Therefore, let's look at how to get rid of temporary files using the tools built into Windows 7.

To do this you will need to do the following:

Advice. Deleting temporary files is much more effective special utilities eg CCleaner. They can often perform additional functions, allowing you to increase the speed of the system.

Viruses

Computer viruses pose a big threat information security V modern world. They are capable of destroying important data, stealing payment information or have a significant impact on the speed of the computer.

Let's look at the main signs of a virus infection:

• reduction in work speed;
• appearance of strange files and folders;
• disappearance of information;
• error messages appear;
• strange processes causing heavy CPU load.

When signs of infection first appear, you must scan your PC to detect an “infection” by established means protection.

Not always installed antivirus can detect all threats that have penetrated the user’s computer.

Difficulty using the browser

Often, users may experience decreased performance while browsing the Internet. It is most often associated with the installation unnecessary extensions and toolbars.

Let's look at how to remove unnecessary toolbars inWindows 7:

Unused add-ons should also be disabled.

Do it inYandexBrowser can be done as follows:

In most cases, performing these simple actions allows you to significantly increase the speed of opening pages and working with the browser.

Hard drive problems

Having problems with hard drive very often this leads to a situation where the computer freezes completely or opening applications is very slow.

All problems related to the hard drive can be divided into the following categories:

• hardware faults;
• logical errors;
• large data fragmentation.

The most difficult option is if the hard drive has bad sectors. They significantly slow down the operation of the entire system and may be evidence of imminent failure of the hard drive.

You can check for bad sectors using the built-in Windows tools 7.

To do this you need to do the following:

During the troubleshooting process, bad sectors will be replaced with working ones from a special area of ​​the HDD. It should be taken into account that a large number of Bad blocks indicate the possibility of an imminent hard drive failure. It is better to copy important data to avoid its loss as soon as possible.

Many programs in startup

Many programs are included in autorun when installed. Of course, the user can refuse this option, but as a rule, they do not. At the same time, any application running on the computer reduces the overall performance of the system. Therefore, it is recommended to disable unnecessary programs in startup.

You can remove an application from autorun using standard means or using special utilities.

Let's consider how inWindows 7 remove an application from startup using the tools built into the OS:

Low hardware performance

On Windows performance 7 can also be influenced by the power of the computer hardware. This is especially true for PCs that were purchased 5-7 years ago.

The main components that affect the speed of the system:

• CPU;
• video card.

The easiest way to get rid of brakes due to outdated components is modernization. During it, outdated PC components are replaced with more modern ones. But it is always necessary to ensure that the purchased parts are compatible with those already installed in the computer.

As a rule, problems that cause a decrease in performance are not associated with breakdowns of computer parts and therefore can be easily eliminated by the user. If this fails, it is better to contact a service center for help.
