The computer slows down hard what to do. Slows down the computer

I welcome you, dear visitor of the Penserman blog.

Many users, especially those who do not devote proper time to caring for their computer, are faced with the fact that it starts to “fail” or work slowly. So, computer slows down what to do?

This problem is very extensive, and there can be many reasons. The main ones, which account for 80% of all cases, are as follows:

  • There is a virus in the system.
  • A lot of programs have started automatically.
  • Many unnecessary processes started running.
  • You have not restarted your computer for a long time, leaving it constantly on.
  • The system has become very littered with many settings, settings, etc.
  • A recently installed program is at fault.
  • On the logical drive, on which Windows is installed, there is little free space left.

The system got a virus

This item is number one, because this is the main suspicion for “glitches” and other “brakes”. Therefore, without delay, we proceed to a complete (precisely complete and no other) check of the system for viruses.

This process is usually very long and takes up to several hours, so it is better to run it at night when all the household members are sleeping. Here, I think, there is nothing special to paint - double-click on the antivirus icon and start the scan from the main window.

Lots of startup programs

Many programs installed on a computer prescribe themselves at autorun, that is, they run along with the operating system when turned on and thereby increase this time, that is, it slows down at startup. And then, all the time they are in working condition, again exerting an additional load on the system.

And we don’t need this at all, so we call the “Start” menu, select “Run”, if you don’t have such a command there, then this window can be called up by pressing the Win + R key combination, and then we type “msconfig”:

After that, in the next click on “Startup”, we look at what we need at startup. For example, four are enough for me, I launch the rest as needed. Then "Apply" and "OK":


This usually requires a reboot. If you have never looked here, then for sure you can easily throw out a dozen programs from autorun and thereby provide all possible assistance to your “intellectual friend”. At the very least, the launch of the system will definitely speed up.

Running unnecessary processes

This point is also important, since processes can be not only unnecessary, but also malicious. But in order to exclude “bad” processes, you need to clearly understand which process is responsible for what. Description system processes, including malicious ones, if necessary, can be found on the Internet or in specialized literature.

In one of my books, this list occupies 8 sheets, so I won’t post it here and I won’t describe the actions either, and later I will devote a separate topic to this. You can view these processes by calling the dispatcher windows tasks. Press Ctrl + Alt + Del, then “Task Manager” and in the “Processes” window that appears:


About the need periodic restart of the computer write, I think there is no need, here and so everything is clear what to do. Let's move on to the next point.

The system is littered

This is one of the main reasons why the computer slows down and cleaning is exactly what needs to be done not least. The CClener program will help us with this. I use it and consider it one of the best for this purpose. If you don't have it installed, then download free version You can from the official site:



In the same program, search for errors in the registry. It happens that because of these errors the system slows down. Now you need to select “Registry”, then “Search for problems” and “Fix”:



By the way, CCleaner also allows you to manage autoload. To do this, select "Service", click "Startup", "Windows". Select the one you need and “Enable” or vice versa “Disable” what you consider necessary:


But it’s somehow more convenient for me to manage autoload from the system configuration window, which I described above in the “autorun check”. Well, how do you like it.

If you paid attention to the program service, there are also such items as “Uninstall programs”, “Erase disk” and “System Restore”. Here is the last point that we will consider in more detail.

A recently installed program is at fault

Sometimes it happens that the installation of programs is incorrect, or some of the new ones, for some reason, come into conflict with the existing ones, which leads just to the fact that slows down the computer. What to do? This is where you need to take advantage of the opportunity in the CCleaner program mentioned before:


Or you can use the tools yourself operating system. To do this, click "Start", right click on “Computer” or on its icon on the desktop, also with the right mouse button. Then, in the drop-down menu, click on "Properties".

After the described manipulations in windows 7, the “Control Panel - Homepage". We select “System Protection”, in the following “Recovery”:


Not enough space on Windows logical drive

Here you have to puff and figure out which files to leave and which ones you can delete. This business, of course, is a chore - it's the same as putting things in order in a pantry or garage. Until I’m ready to throw everything away, but in the process of cleaning it turns out that everything is needed. And yet, if your "pet" slows down, you have to do it.

But to calm your conscience, before this difficult task, you can clean up the disk Windows tools. Right-click on the system drive, select "Properties", "General", "Disk Cleanup":

In the next window, select what we will delete and “OK”. There is nothing complicated, I think you will understand.

Here, perhaps, are all the main reasons for the slowness of the computer. There are, of course, others. For example, purely on hardware, but we will not analyze them and limit ourselves to only these basic ones. I hope now you will not have a question: why slows down computer and what to do?

Good luck to you! See you soon on the pages of the Penserman blog.

Perhaps your computer is simply not enough memory. V modern computer must have at least 2 gigabytes of RAM. Despite the fact that the price of memory is now simply ridiculous. In the windows task manager, you can see how many random access memory busy at the moment. If your computer is running Windows 7 and it is running too slowly, the reason is most likely a lack of memory. The only solution in this case is to increase the amount of memory by installing an additional module.

In general, Windows 7 can be run on a computer with 1 gigabyte (GB) of RAM, but 2 GB is better. 3 GB or more of RAM provides optimal performance.

Another option is to increase the amount of memory using Windows ReadyBoost technology. This feature allows you to use storage space on some removable media such as USB flash drives to improve the performance of your computer. It is much easier to insert a flash memory device into a USB port than to open the computer case and connect memory modules to the system board. For more information, see Use storage memory to speed up your computer.

And the very last and main advice is to monitor your computer, do preventive maintenance regularly, and then it will definitely not slow down!

If you often have to sit in front of the monitor screen, and you notice that the computer starts to slow down at startup, you need to find out the reason. It is useful for each person to know the root causes of these problems and their solutions, since no one can guarantee that you will avoid the same problems in the future.

Main reasons

We list the main reasons why the computer began to slow down:

  1. insufficient RAM;
  2. overflow hard drive; .
  3. resource-intensive programs or games;
  4. a lot of unnecessary system files;
  5. installing a new device or driver;
  6. virus software;
  7. clogging the system registry;
  8. hardware factors.

    9. Let's consider them in more detail.

    Not enough RAM

    When there is not enough RAM, programs start to stop working, start to function more slowly, or become unresponsive. To avoid this situation, try not to use multiple applications at the same time. You can also solve the low memory problem by following these tips.

    Volume Up virtual memory(swap). Keep in mind, however, that too much swap space often slows down the performance of most programs.

    To increase volume you need:

  • go to the "System" component (Start - Computer - Properties);

  • click on Extra options systems;

  • find the Settings button (Advanced - Virtual memory);

  • uncheck the box next to Automatically select the size of the paging file;

  • go to Specify size, enter the required number in the field Maximum size, then click on Install and OK.

Make sure the program does not use too much memory. If there is a memory leak, close the program in question and install updates for it.

But how do you know which program to terminate? For this:

  • click on Task Manager;
  • go to Processes;
  • click on Memory;
  • select the option - memory usage;
  • sort the programs you use.

    • Another option is to install an additional RAM module.

    Hard drive full

    The hard disk is divided into logical partitions, and the system uses the partition, which is called active.

    Here are 6 reasons why a computer slows down due to a hard drive:

    • the system partition is initially small;
    • all installed games and applications the system transfers to this section;
    • it accumulates temporary files and system recovery files;
    • games save save files in the active partition, the sizes of which are often huge, especially in today's powerful games;
    • the desktop is also part of the active section, which is often a place where various user information (videos, photos, music files, etc.) is collected;
    • not enough RAM.

      • All these problems can be easily solved. Delete temporary files (for this, install a cleaner program), old system recovery files. If you're not playing the game, move the save files to the Trash. Clear your desktop of folders and files, leaving only shortcuts. Another way is to create additional partitions on the hard drive for games, programs, movies, etc.

      Resource-intensive programs or games

      The processor usually has the simplest factory cooling system, so if you use the computer for the Internet and work in office programs, then you won't notice any problems.

      But if you often use resource-intensive games and programs, then you have two options:

      • change the factory system to a more modern and powerful system;
      • install an additional cooler.

      Lots of unnecessary system files

      To clean your computer from system and temporary files, use Windows utility which is already built into the system. For this:

      Such an operation can "lighten" your computer by several gigabytes, speeding up its work.

      How to find out why the computer slows down

      Consider 2 reasons why your computer may slow down and deteriorate:

      • after installing a new device;
      • after installing the drivers.

      Sometimes a new touch keyboard or LTE modem can worsen the performance of a computer, which happens due to driver conflicts or because the developer wrote a driver with errors. In the latter case, you will have to install an alternative version of this driver.

      But what to do when turning on the computer to resolve the conflict? For this:


      Select those drivers that have a red or yellow exclamation mark next to them, then uninstall them and reinstall them. This will also have to be done when there are duplicates of previously installed drivers.

      Startup programs

      Most of the programs you install will start automatically downloading according to their schedule, but this is usually not necessary for the average user.

      To remove programs from startup:

      • click on Start;
      • in the search below, type in the word Run;
      • in the field of the window that appears, type msconfig;
      • click OK.
      • after that, uncheck unnecessary programs;
      • click OK.

      You do not need to uncheck the boxes next to firewalls and anti-virus programs.

      And typical programs that you can safely remove from startup include Download Master, Winamp and Adobe Reader.

      Virus Software

      If your computer has become a victim of hackers, you can use antivirus programs to remove virus software.

      They are of the following types.

  1. the firewall performs a filter of traffic passing through the network, and in case of attacks it starts blocking it, and also blocks attempts to gain access over the network without authorization;
  2. the monitor checks for the presence or absence of viruses all the files that you run on the computer;
  3. the scanner performs 2 functions - it scans files and cleans them of viruses.

To the most common antivirus programs relate:

  • Antivirus Kaspersky;
  • Avast;
  • Dr. Web;
  • panda;
  • NOD32;
  • Trajan Remover;

But even the most powerful antivirus program does not guarantee 100% protection against viruses, so never start running all downloaded programs on your computer in a row, and also try not to run programs from unverified publishers and do not click on everything in a row links in letters that you receive by e-mail.

Do not install more than one antivirus program, as this will reduce the effectiveness of the scan and will only exacerbate the problem of slow computer performance. Also, regularly keep the program database up to date.

Clogging the system registry

The system registry, like HDD, needs cleaning from time to time. It usually gets clogged due to established programs keys or unprofessional work on the computer leading to errors.

To clean the registry, use one of the programs listed below, but remember that you must create a registry backup before the procedure:


Hardware factors

Hardware factors that adversely affect hard drive performance include the following:

  • the integrity of the blocks of magnetic heads is broken;
  • disk surface is damaged;
  • the plates are offset relative to each other;
  • due to the fall of the HDD on something hard, the mechanical part of the hard drive gets dented, the pancakes stop spinning, when the disks rotate, a cut, click and rhythmic knock is heard, as well as various whistles and hisses.

You need to contact service center for professional HDD repair.

Pay attention to the temperature of your computer. To control it, set Everest program. The Gauge tab will show the value - make sure it doesn't exceed 50 degrees.

Otherwise, you can do the following:

  • blow out the radiator;
  • check fans;
  • remove the heatsink to apply new thermal paste to the computer's processor.

Reasons why media files and sound slow down

If the game takes a long time to load, and after that the mouse freezes, and the image is displayed with errors or the sound slows down very much, then the reasons may be as follows:

  • your processor is weak enough for such operations;
  • you need to reinstall codecs.

Video: why and what to do if the computer slows down

But music and other media files can slow down for all of the reasons listed above, so use the tips that we indicated earlier. We hope that this article will help you solve most of the problems related to the operation of your computer.

With the correct diagnosis of slow work and the right solution, working at a computer will become pleasant and comfortable, so we strongly advise you to devote enough time to diagnosing problems and solving them.

If your computer is slow and often freezes, follow the simple recommendations from this article and you will significantly speed up its work. When you install extensions, surf the web, create documents, and fill your hard drive with movies and music, it's inevitable that you'll have an impact on performance. Let's take a look at the most common causes of system slowdowns and the simple steps you can take.

Disable the most resource intensive programs

Most likely some utilities use system resources. Some software occupies a large amount of RAM, and this causes the paging file to be consumed.

To determine this, launch the "Task Manager" (on the keyboard, hold down Ctrl + Alt + Del and select the appropriate item).

Click on the following buttons: "CPU", "Memory", "Disk", and sort the list by processes. If you see that the program consumes a lot of resources, close it (select with the mouse and click "End task").

Close applications in the system tray

Running utilities are visible in the system tray or in the notification area. They start when the system starts and run in the background; they can be seen by clicking on the arrow icon in the lower right corner of the display. Click this icon and identify the software you will no longer use. By clicking on the right mouse button, turn it off to free up resources.

Disabling auto-loaded programs

For more fast loading, and also in order to save free memory, it is better to remove some utilities from startup. Go to the "Task Manager", in the "Startup" tab, turn off what you do not use. You will see which of the list slows down your startup process the most.

Windows applies animation effects, which can slow things down. To turn off the function in the Start menu, go to the "System" tab, then "Advanced" and open the "Settings" item. Check "Ensure best performance".

If you recently updated the configuration, the driver may not have been installed correctly. Find it in Device Manager and double click on it. In the dialog box that appears, click the "Driver" tab and then "Roll Back". If the button is not available, the problem is something else.

If you have added new hardware, try disabling it. Find it in Device Manager, right-click it and click Uninstall.

Lighten the Browser

When you use your web browser frequently, it will slow down over time. In the settings, select "Clear History". You will notice a significant speedup.

Free up HDD space

If there is not enough free space left, this may be the cause of the slowdown. Make sure you have at least 1 GB free on the drive where the OS is installed. This available space will allow you to have spare space for the swap file as well as space for temporary information.

To clear the HDD, you can use third-party software, or simply run the solution that is included with Windows. From the Start menu, select Run and type

Deleting temporary files

Some applications store temporary data while running. Removing them will improve the performance of your computer. To do this, open Start and type %Temp% in the search box and open the folder. You can easily delete all information.

If the old machine is slow

If the PC is more than seven years old, this is most likely the cause of poor performance. Latest Versions The software is optimized and more efficient, and older machines are not able to run it, or work with them very slowly. To optimize, you will have to consider purchasing new hardware, or accept that the device will not be as fast as a newer one.

RAM upgrade.

If your PC is more than two years old, you may need more RAM. If you have enough memory to run the utilities, you do not need to load the information that is stored in the paging file.

If the HDD indicator is constantly on, this is a sign that the OS is frequently communicating between RAM and the drive.

HDD upgrade.

The best upgrade option is to upgrade the HDD. Installing a solid state drive will greatly improve productivity. This is the cheapest and most efficient solution.

Modern computers have a fairly high performance. Even the cheapest system unit works an order of magnitude faster than gaming computer ten years ago. Unfortunately, sooner or later, any user of a personal computer is faced with a significant slowdown in the system. 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 the performance of the PC. However, you can identify a number of the most common causes, 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 related to the ingress of malicious software into the operating system. Fortunately, PC virus infection can be easily distinguished from other factors. After getting into malware, the computer not only slows down, along with slowdowns in the interface, the operating system regularly crashes. The most common signs of a virus infiltrating a 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
  • User File Encryption
  • The appearance of advertising on the desktop

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

One way or another, a person has only one way, install reliable anti-virus software and conduct a full system scan, agreeing to delete "incurable" files.

The most reliable antivirus programs include: dr. Web, NOD32 and Kaspersky.

What advice can you give users? Everything is very simple, after Windows installation, the first step is to install antivirus software, after which, the user needs applications only from official sites, in extreme cases from.

Splitting a hard drive into two local drives is certainly useful. For any problems with the OS, the user simply reinstalls the system.

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

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

To clean up garbage, the easiest way is to use CCleaner, whose database 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.

One more piece of advice can be given. V Lately more people are using Google browser Chrome. This browser has one convenient feature, namely, the creation of multiple profiles. Many people are fond of this feature, creating dozens of profiles, and one profile takes up about 500 megabytes of disk space.

Surely, for many users, the situation is familiar when the computer is relatively stable, but when you start, even the simplest game, the PC starts making 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 simply do not know that a computer is not a TV or any other electronics. Structure system block it is arranged in such a way that during the day, a huge volume of air passes through its body, and with it, dust also gets on 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 not able to properly cope with the cooling of the computer.

To check the temperature of the power supply, just put your palm on the back of the case, in some cases, the temperature is such that you simply cannot 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, as a result, the PC will simply fail.

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

Gradual hard drive wear

Each part in the system unit has a limited service life. Nevertheless, some components fail earlier than others, for example, the processor rarely fails, while the hard drive works stably for no more than five years on average.

The life of a hard drive most often depends on the quality of manufacture, however, some user actions can significantly extend the life of the component.

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

The structure of the hard disk is arranged 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 over the entire surface of the hard drive, looking for the necessary information; accordingly, over time, the moving mechanisms wear out a lot. Defragmentation is just intended to group information about a file in one place, instead of looking for it all over the drive.

Lack of RAM as the cause of computer slowdown

When you start any application, its data is loaded into, respectively, the more difficult the task is set for the system, the more RAM will be spent on its execution. Some modern games require at least 16 gigabytes of RAM.

The lack of RAM is especially acute when working with browsers. The more tabs open, the more RAM is loaded.

There are many solutions to this problem, for example, increase the size of the paging file, due to which, after the RAM is full, the data will be charged to a dedicated 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 customer is using DDR2 or DDR3 and decides to upgrade to a newer type of memory, DDR4, along with RAM, they 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 CPU All calculations are done on the computer.

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

Many PC users are trying to increase the frequency of the component, but unfortunately, this can not be done with every processor, and the received power will still not be enough for complex calculations.

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 prevents you from getting started quickly, but also affects the overall performance of the system.

To disable autoload, in the settings of each program, you must uncheck the box "load the program with Windows".

You should leave autoload only in those programs where it is really important, for example, antivirus software or virtual disks Alcohol 120%.

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

Over time, the registry becomes filled with junk left by remote applications, which prevents the system from working as it should.

To solve this problem, you must either be well versed in the registry, or use the same CCleaner application, which will automatically remove all unnecessary entries.

Slows down the computer when working with the browser

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

Indeed, sometimes it fails. Flash 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 should simply replace the obsolete components of the system unit. In addition, it will not be superfluous to clear the browser cache and browsing history from time to time.

We have analyzed the main reasons why a computer slows down. For stable operation of the system, regular maintenance is necessary. personal computer both technical and software. With careful handling computer technology computer can last for many years.
