Why the laptop is buggy and freezes. Laptop hangs: troubleshooting

When using a laptop, an unpleasant situation often happens - in one not very beautiful moment, the computer suddenly starts to slow down, hang up and stop responding to commands. Why is this happening and what needs to be done to return the laptop to its normal state? Let's try to figure it out.


Causes of a laptop hang

Immediately it should be noted that there is no single cure for all diseases, and typical cases of loss of the normal operation of the device will be considered.

The most common causes of a hang are:

  • Overheating laptop;
  • Insufficient RAM;
  • The presence of viruses or malware in the laptop;
  • Hard drive damage;
  • The accumulation in the Windows registry entries, slowing down processes;
  • Low processor performance
  • A large number of programs installed in the system startup;
  • Hard disk overflow with information, its fragmentation is also possible.

All reasons are divided into two categories: in one case computer hardware is to blame for the hang, in the second - failures and malfunctions of the operating system.

Consider in order all possible sources of problems.

Laptop hangs due to computer hardware

Overheat

For many laptops, overheating becomes the # 1 problem. Unlike a desktop computer, it doesn’t have much space for additional CPU cooling fans, and the performance of desktop PCs is usually higher. The reasons for the overheating of the laptop can be the following:

  • Factory defect;
  • Memory overload;
  • CPU cooling fan failure;
  • Accumulated dust inside the case.

If you read the forums reviews about a particular model of laptop, you can often find complaints that the gadget is very hot. In such cases, the “laptop” usually starts to slow down on the “heavy” programs that heavily load the processor. Often, the device is completely turned off, and it can only be turned on after it has cooled down a bit. In general, what can be done to try to get rid of this problem?

  • If the laptop is not new, you can try to clean it from dust. Often dust clogs the processor fan.
  • It happens that a new computer device is also heating up. Alternatively, you can buy a special stand with a cooling fan. The support well helps out in many cases, only it is not necessary to save on purchase. Checked that the cheap stand - money, thrown to the wind.
  • It is worth listening to the work of the laptop. At considerable heating the fan should turn on. If it is not noisy, then perhaps it needs to be replaced.

Lack of RAM or CPU performance


Now many programs have been created that, for all their merits, consume quite a lot of computer device resources. Suppose a new computer game is designed for 2 GB of RAM, and all RAM on a laptop is 4 GB, and Windows 7 is installed. It seemed that the game should go without brakes, but it is not all that simple. The fact is that Win 7 itself takes 1.5 GB of “RAM”, and only about 0.5 GB remain free. And if one of the browsers or any other applications is open (Skype, ICQ)?

With a lack of computer hardware performance, there are only two ways out:

  1. Upgrade the laptop (increase the RAM, install a more efficient processor, if the motherboard allows it).
  2. Try to use those programs that do not overload the laptop.

Hard drive freeze

Unlike a desktop PC, a hard drive (hard disk) is a particularly vulnerable place in a laptop. The fact is that a laptop is still basically a portable device, and often subject to various movements. When moving, any shake-ups and even blows are possible. But just strikes the laptop hard drive and is afraid. When hitting the hard disk, so-called “bad blocks” (non-working sectors) are formed. If such bad blocks accumulate a lot, the computer will first start to slow down and then may refuse to work at all.

It is difficult to advise something with such a problem for an ordinary user, but sometimes it is not so easy to figure out the hard disk. In Win 7, you can check the hard disk as follows:

  • “My computer →.
  • Local C drive (or other letter) →.
  • In the free field, right-click "Properties" →.
  • Service →.
  • Check disk for errors (button "Run check").

To identify non-working sectors on the hard drive, there are special programs with which you can and "cure" the hard disk. Not all disks are “cut”, sometimes the hard drive is easier to replace.

Another problem is hard disk fragmentation. Fragmentation occurs due to the fact that information is written to different sectors, and when reading it, the computer has to go to all areas of the disk to read the contents. There is a delay, the laptop for a long time "thinks" when reading information from such a hard drive.

With such a mess, the situation is simpler. In any Windows, starting with Win 95, in standard programs there is a utility “disk defragmentation”. In Win 7, it is located at: “Start → All programs → Accessories → System Tools → Disk Defragmenter”.

Laptop hangs due to operating system

Viruses and Malware

Viruses, penetrating into the Windows system (we will consider it as the most common), can significantly slow down all processes in the laptop. The problem is solved with the help of antivirus programs, but sometimes the situation reaches absurdity. The laptop slows down and hangs precisely because of anti-virus software.

As a piece of advice, you should not download trial versions of antivirus products on the Internet. And it doesn't even matter how well known this program is, whether it is Kaspersky or dr. Web. Especially you should not use the demo version with a weak configuration of computer hardware - the laptop will be terribly slow to brake almost guaranteed. The fact is that with the program different side applications are installed, and they do not ask for installation permissions. And those checkboxes that were necessary to remove when downloading the demo antivirus, not everyone notices. So we get a bunch of additional problems instead of preventing the operating system.

Overflowing the operating system registry with unnecessary entries

Some programs that are no longer needed, the user removes from the computer. But the registry entries about the program are saved. Accumulating in the Windows registry, these entries begin to slow down the computer. Therefore, the registry must be periodically cleaned. For cleaning records, there are many different utilities, including free programs. Such programs can be found on the Internet; for example, the CCleaner utility. But to use such software you need to carefully and closely monitor what is removed from Windows.

If you do not have the opportunity or desire to independently determine the cause of the system hangup, feel free to leave a request on the website or immediately call our consultants!

Most people who purchased a computer or laptop a few years ago, and perhaps recently, may encounter such a problem as its hanging up or braking.

Your electronic friend may hang up in many cases, but this happens mainly after switching on when you boot Windows or some time after logging in to the system, as well as in games, watching a video or trying to open a file with the program.

We will tell you why this happens and what to do in such cases. This manual is suitable absolutely for all versions of Windows: XP, 7 or 8th version.

So, here are the most common reasons why a computer or laptop hangs (not all of them can be fixed in a laptop):

8 software reasons why a computer or laptop hangs

01. First, you should check your computer for viruses. need to install immediately after buying a PC or laptop, it is better to update the anti-virus database on a daily basis. If a virus is found, send the infected file to quarantine or delete it. After reboot the system.

02. Curves of the video card driver and other components, or their conflict can cause the machine to hang and go to the blue screen. Check the conflict and you can in the device manager (see photo).

03. Even despite the fact that you are the owner, by today's standards, a powerful computer monster - you still see "brakes" in one of your programs or games, then most likely this application is still raw or incompatible with the Windows version. It is worth looking for an updated version or a fresh patch for the application or go to the current version of Windows.

04. Windows operating system has the property clogged with time. For there are lots of programs, both paid and free, which are easy to find on the network.

05. Windows files may have been damaged. You can recover files by rolling back the system or performing system recovery through the Windows boot disk. If the first two options did not help, then you will have to completely reinstall the operating system.

06. Many programs work in the background, consuming resources considerably, and the owner can even not guess about them. Try to remove all unnecessary programs and clean the system behind them.

07. Check the paging file on the hard disk, perhaps its volume is small or because of the full hard disk the system cannot receive the required volume.

08. If you find hangs, or jerks only when surfing the web, then you probably have insufficient Internet connection speed, or you should use another, faster browser.

8 hardware reasons why a computer or laptop hangs

01. The first thing to check is the load state of the RAM, processor, video card and hard disk. After all, over time, it is this reason that can provoke slow work, as more modern programs are increasingly demanding on data processing speed.

To check the percentage of the required device load, just go to the Task Manager in the Performance tab (see photo).

02. Overheating of the processor, video card, motherboard chipset or hard drive also slows down the computer. The cause of overheating may be the dusting of components or the drying of thermal paste in the connecting places of cooling elements with components. In order to prevent the occurrence of this problem, it is enough to carry out internal cleaning of dust once a month and change the thermal grease once every 10-12 months. And maybe it is worth replacing the cooling system with a more powerful one, especially for those who like to play games at maximum settings.

03. Also the cause of freezes, leaving in the blue screen may be a breakdown of the hard disk. In this case, it is worth checking the hard disk for errors using special programs, or another computer. This will help determine whether to replace this item.

04. A poor-quality cable (sata, esata) of a hard disk or connecting contacts of a cable can cause significant braking in operation. In order to determine if there is a breakdown, you must try to replace the cable with a working one. And in the future it is better to use only proven manufacturers, for example - Akasa. Pay attention to the cable length, for certification it should not be more than 0.5 m.

05. The problem may also be covered in a broken power supply or its insufficiently developed power. The easiest way to identify a problem is clicks from the system unit. They can be caused by 2 reasons: an unstable voltage in the power supply network or a power supply unit has failed and cannot provide the necessary voltage for a video card under load, after which its work also gets worse. But if there are no clicks, then you should not relax, just in case, check it for the output power and power requirements of your components.

06. Incorrect BIOS settings for installed components also cause problems with the system speed. Not everyone can perform its optimal setting, so you may have to turn to experts.

07. Updating the firmware of the motherboard - BIOS, sometimes solves a number of problems of slow work. In the new firmware, developers solve problems with previously detected bugs and improve the capabilities of the motherboard. Check for updates for BIOS, you can on the website of the company that developed your motherboard.

08. As we wrote above - the requirements of resource consumption of modern programs are growing every day. Therefore, the replacement of components that are slow by modern standards is inevitable, and maybe the entire PC.

P.S.
Of course, not everyone is well versed in the architecture of the computer and the "insides" of the system unit and, of course, not everyone can do what is listed above independently. Therefore, to get started, eliminate the simplest of causes that may be a problem. For example, check for viruses, delete unnecessary files, clean the dust from the system unit. If, nevertheless, these actions do not make the situation better and the hangs do not disappear, then bring your electronic friend to the service center for repair.

If you didn’t manage to correct the problem yourself and you have any questions, or if you know another possible reason why the computer or laptop hangs, write about it in the comments.

Why does the laptop hang? This is one of the most popular questions in service centers. The reasons for this may be the mass from overheating the device to clogging or obsolescence. Today, many, to save money, try to eliminate the problem on their own. This article will help, without turning to specialists in a short time to solve this problem.

Common Causes of Slow Laptop Performance

As a rule, the most common cause of a laptop hang is an overflow of RAM. Moreover, if earlier for a comfortable and fast work of the machine it was enough 2 GB, but today they are critically not enough. And the reason for this is the overflow of a computer with a variety of games and programs. However, today, there are some viruses that are able to fill the operating memory almost completely.

The system may slow down due to the large number of open windows on the Internet or programs. To quickly and comfortably work with a laptop, you need to learn the simple and simple rule “Worked, closed the program”, so you do not reboot the system, which is why it continues to work quickly for many years. By the way, the best way to do this is not only clicking on the "cross", but also in the "Task Manager." Speaking of the "task manager" can be noted that at the same time during normal operation of the laptop can occur up to 50 processes.

The most popular reason for slow computer performance are viruses and spyware. Malicious programs start up on your device regardless of your desire, so after the first symptom you need to check for viruses. To do this, on the limitless expanses of the Internet, you can download antivirus software.

Almost every day we install or uninstall any programs, but even after cleaning the disks, some files remain, clogging up our computer. Therefore, to prevent the computer from hanging up it is necessary to do it regularly.

Technical reasons for freezing the laptop

In addition to systemic causes, freeze laptops can run slower due to obsolescence or breakdown. Important technical parts that can break down and thus cause a slow laptop, are:

  • Motherboard
  • Video card
  • CPU
  • RAM

In the laptop, for each such detail are designed fuses that overheat in case of obsolescence or breakdown.

Of course, it is problematic to fix this kind of damage yourself, especially in a laptop. That is why the best way to solve this problem is to contact the service center.

Easy ways to “cure” a laptop instantly

The easiest, and classic way is to restart the computer. If the computer is frozen for the first time, then perhaps it was a single system failure, which, just after such simple actions, would stop. However, if your iron friend hangs constantly, then the problem may be much more serious, but at least you can solve it using the Restart function.

One day, every laptop user is faced with slowing down a computer. The older the computer, the more often it “tupit” - this is not surprising. Complicated software increases the system requirements for computing capabilities of the device.

It slows down the laptop what to do windows 7, like any operating system is also overwhelmed with errors, "tails" from remote and reinstalled programs.

Where to start the search? Strongly "tupit" laptop, what to do (windows 7)? Consider some of the factors that are most common and affect the inhibition of data processing.

The most important symptom of an electronic disease is old age.

The diagnosis can sometimes be made independently, without the involvement of specialists. With the left mouse button, we turn on the “Start” button, raise the cursor to the “Computer” label, press the label with the right mouse button, drop the cursor to the “property” label, and press it. The window that opens in the "System" section will tell us about the main characteristics:

  1. Evaluation (digital value of the performance index Winds).
  2. Processor (manufacturer, type, name, core clock frequency).
  3. Installed Memory (RAM) is a random access memory.
  4. The type of system (64 or 32 bit OC).

We turn on the inscription “Windows productivity index” with the left mouse button, in the opened window we read “Evaluation and increase of the computer speed”. In this section, you can see which of the indicators has the lowest performance score. Modern games and video processing products have high hardware requirements for hardware performance.

The performance index specified in the product description must match or be lower than your PC index. Otherwise, there will be slowdowns and slowdowns. Sometimes you can improve performance by installing more RAM (RAM), possibly replacing the processor, video card, if the design of the device permits. Replacing the hard drive with a solid-state drive can significantly speed up the exchange of processor data. In another case, you will have to use programs with less requirements, or replace your PC as hopelessly outdated.

Hard frame unfavorable disk space

With the left mouse button, turn on the “Start” button, raise the cursor to the “Computer” label, press the label with the left mouse button. In the window that opens, the disk space appears. The blue color of the hard drive strip indicates normal fill. Red color indicates the lack of free space, the need to free part of the disk for further work.

One click of the left button select the desired disk. Then, with the right button, we call up the menu, and with the left, we press the sign “Properties”. Click "Disk Cleanup", then "OK". If the color of the strip remains red, then you need to delete part of the files or move them manually to another medium. In this case, it may well be cloud storage, another hard disk, or another suitable storage medium.

If there is not enough space on the system disk itself, then Windows 7 will be very slow.

Damage to system files

Go to the "Properties" menu, the "Service" tab, enable "Run scan", then "Start". We put "birds" - "Automatically correct system and other errors", "Check and restore damaged sectors."

Windows 7 will offer to check the system hard drive for failures at the next PC startup. We include "Schedule check". The next time you turn on the laptop, the scan will be automatically turned on. The hard disk will be checked for errors.

File defragmentation technique

In the “Properties” menu, the “Run Defragmentation” tab allows the operating system tools to place the necessary data on the hard drive in the most convenient way for Windows 7. To reduce the time spent on finding the necessary information to a minimum. In the opened tab you will see the status of the hard drive. After analyzing, you may see Windows recommendations on the need for defragmentation. Defragmentation can take quite a long time, therefore it should be turned on according to a schedule.


Page File and Visual Effects

What to do if the laptop slows down and hangs in windows 7? To speed up the laptop, you can use the capabilities of the OS. Go to the tabs "Start" - "My Computer", click "Properties". The next inscription is “Additional system parameters”, including “Speed”, “Parameters”. Then "Visual Effects" and "Ensure the best performance." In this mode of operation, windows 7 will significantly simplify the view of the interface, the windows will become very primitive. This will relieve the RAM, slightly speed up the laptop.

In the same place, select the "Advanced" tab in the "Virtual Memory" section, go to "Change", set the "Automatically select paging file volume" checkbox or specify the size in accordance with the recommended one in the lower part of the window. The paging file allows windows to reserve a portion of the hard disk to save the most frequently used information.

Viruses and Antivirus

It often slows down the laptop and hangs due to the presence of viruses. Therefore, antivirus should be used to prevent periodic removal of viruses:

  • Ad-Aware;
  • Avast;
  • Avira;
  • Bitdefender;
  • Comodo;
  • Kaspersky;
  • Panda;
  • Qihoo 360 Total Security;
  • Sophos Home;
  • ZoneAlarm.

Antiviruses themselves also use resources, so because of them, too, may be slowing down the laptop. Therefore, when choosing an antivirus, it is necessary to consider its system requirements. If you need to speed up the laptop, you can temporarily disable antivirus.


Rubbish in the registry

Professionally clean the registry can only experienced professionals. For ordinary users, there are a number of utilities that allow this to be done with minimal risk. For example, "CCleaner". In the free access on the website of the manufacturer of the product, you can download a trial version. Download and install this utility - turn it on. The "Analysis" button activates the process of checking temporary and obsolete files. "Cleaning" removes them. This operation must be performed several times, ensuring complete removal of unnecessary files. It should be noted that CCleaner does not know what is important for you in the history of browsers, and what is not, therefore, when choosing the files to be deleted, look carefully at what you delete.

The "Registry" button switches to the registry check mode. Turn on "Search for problems." After the end of the search, click "Fix". Further, the utility will offer to save backup copies of all changes made to the PC, you should agree. If the PC malfunctions after fixing the problems, it will be possible to restore the registry using a backup copy.

Programs and components

Sometimes the hard drive is cluttered up with unnecessary programs, so that we can remove them sequentially by the inscriptions. “Start” - “Control Panel” - “Small Icons” - “Programs and Features” - a list of all installed programs will open. Select unnecessary from the list, then delete.

Autoload

In the search bar, enter “msconfig”, turn on the detected utility, select the “Startup” tab in the window, select unnecessary programs from the list that appears and remove the “bird” in front of them. Then "apply." Autoload is only needed to automatically enable the really needed utilities. Some programs automatically, self-register in autoload.   Constantly load the RAM, although there is no need for this. Therefore, by prohibiting them from automatically turning on, you will thereby greatly facilitate the operation of the device.

Violation of temperature

The reasons for the emergency temperature can be many. When the main processor or video card overheats, the speed will decrease significantly. This may have led to closed air vents, disruption of the basic elements of the laptop. Utility AIDA 64 will help in identifying violations of the temperature regime of the main elements. Having decided on a malfunction, it will be easier to make a decision on its elimination. A properly formulated request will help you find several practical answers on the Internet.   You should not take at face value everything that you find on the vast expanses of the world wide web.. Before drawing a conclusion, analyze several sources.


Disabling system services in the wind 7

There are many myths about disabling system services windws 7. Often, various sources mention the need to disable unnecessary services to optimize a PC. By opening the "Services" tab, you will find that many services are either disabled or run manually. Disabling even all unnecessary services you will not get a tangible increase in performance.   And in case of an erroneous shutdown of an important PC service, it may stop working or significantly impair your impressions of its work.

Warning

These recommendations should not be followed by users unfamiliar with similar processes. If you doubt your knowledge, contact well-proven professionals. For general information, you can go through all the diagnostic items listed in the article, make the necessary entries for yourself, without changing anything in the settings without uninstalling the programs.

Any user has encountered such a problem as the hang of a laptop. There may be a huge number of factors leading to the fact that the laptop freezes. Let us dwell on the most common causes of this problem and try to answer the question why the laptop hangs?

  1. Insufficient RAM. A few years ago, 1 GB of RAM was sufficient, but today 2 GB is not enough for high-speed work with various energy-intensive programs. And, as you know, games are one of the most expensive in this regard. Also, many users are accustomed to working with a large number of simultaneously open programs, which greatly loads the RAM. Need speed - do not run many programs at the same time. And add the amount of RAM if possible.
  2. Installed spyware. This type of software can be hooked almost everywhere, via the Internet, disks connected to USB devices, on any network, etc. This software without your knowledge can function on a laptop for a long time, watching the work being done. A good antivirus should block them.
  3. Antivirus work. This program loads the system very much. In the process of scanning, most of the CPU resources are occupied by the work of the antivirus, the other programs will slow down their work very much. Of course, you can simply remove the antivirus and enjoy high speed, but in this case the joy may not be long. Hooking up a virus anywhere, ultimately your system will run even slower or just crash.
  4. Overheating of the elements of the motherboard and video card. Very often, the laptop freezes when the performance of the central or graphics processors decreases, which occurs when they overheat. Special sensors monitor the temperature of these devices, and when the set values ​​are exceeded, the protection system reduces the speed of the processors for some time. This saves these devices from overheating, which are not only the most expensive in a laptop, but also the most important. With a critical increase in the temperature of the processors, the laptop simply turns off. With frequent overheating, it is necessary to clean the laptop and it is also possible to use special supports with fans in the future.

If the laptop hangs up what to do, here are some more tips:

  • remove unnecessary programs from autorun;
  • restart the laptop after 4 hours of operation;
  • never set additional tasks when hanging up, this will aggravate the situation even more;
  • run periodically anti-virus scan of the entire system.
  • download from them and run or install on your computer.

If the laptop freezes when turned on, the following reasons are possible:

  • overheating or breakdown of the motherboard;
  • software errors, driver incompatibility.

Contact our service center and our specialists will find the cause of the malfunction and quickly fix it.
