Netbook stuck. Laptop freezes when turned on. Causes and remedies. Exposure to spyware or viruses

A laptop can freeze for many reasons. Sometimes troubleshooting is a rather difficult task, but if you do not find and fix the problem, the computer will freeze regularly, preventing you from using the device normally.

Common Causes

Before answering the question: “The laptop constantly freezes. What to do?" it is necessary to establish the reason causing such behavior. In most cases, the user can handle the initial diagnosis on their own.

All causes leading to freezing can be divided into two groups:

• software, arising from errors in the software or the action of viruses;
• hardware related to malfunction or problems with computer components.

You can solve the problem with the software at home. If the laptop freezes due to a hardware malfunction, then in most cases you will have to resort to the services of specialized service centers.

The most common problems that can cause a laptop to freeze:

1. viruses;
2. program failure;
3. insufficient free space;
4. processor overheating;
5. problems with accessories;
6. errors during the operation of the antivirus;
7. a large number of programs in startup.

Let's take a closer look at the main reasons. This will help in diagnosing the problem and allow you to solve the problem faster.

Presence of malware

A variety of malicious programs can damage or destroy important information on your hard drive. In addition, they often make changes that interfere with the normal operation of the operating system. As a result, the laptop may start to “slow down” or freeze completely.

Users who actively use the Internet suffer most from the action of malware. You can also pick up malware from any media: USB flash drives, disks, and others.

You can avoid trouble with viruses by installing and updating specialized antiviruses on time. In situations where the PC has already begun to freeze, you can check for malware infection with specialized utilities from manufacturers of protective systems.

CPU overheating

The laptop is quite compact device and all the components in it are located close to each other. Modern high-performance processors generate a lot of heat during their work. Naturally, manufacturers try to provide sufficient cooling. However, it is not uncommon for the CPU to overheat.

Consider the main reasons why overheating occurs:

Dust accumulates quickly inside the case of a modern mobile PC and must be removed using a can of compressed air. Failure of the cooling system is less common and must be replaced. Cleaning of dirt can be done at home, and to replace the fan, radiator, and so on, it is recommended to contact the service center.

RAM problems

Incorrect operation of RAM modules can also cause the PC to freeze or other malfunctions. As a rule, defects in this component appear fairly quickly after installation. When looking for reasons why the computer is not working properly, it is recommended that you run a special utility, such as MemTest, and run a test.

If problems are found with the RAM module, it will need to be replaced with a new one. This operation can be performed by the user himself or at a service center. During the warranty period, it is recommended to contact the place of purchase without trying to solve the problem on your own.

Reduced system disk space

In the course of their work, the operating system and programs create a lot of temporary files that reduce the free space on the system disk. When there is no free space left, applications begin to “slow down”.

Solving this problem is quite simple by deleting unnecessary programs and data, as well as temporary files. This can be done by means operating system Windows or using special utilities such as CCleaner.

Program crash

The software may contain bugs, and users often set invalid parameters in the application configuration. These reasons can lead to the fact that the laptop starts to freeze at the most inopportune moments.

Usually, when there are problems related to the software, you can see the corresponding message on the screen. To restore work, you will have to boot Windows in "Safe Mode" and reinstall or remove the problematic application.

The most common problems are due to the following software:

1. drivers;
2. system utilities;
3. applications to increase computer performance.

Antivirus work

Modern antiviruses consume significant computer resources. By themselves, they rarely lead to a computer freeze, but they can have a significant impact on performance.

However, when, after installing the antivirus, the computer began to freeze, it is necessary to reboot in "Safe Mode" and disable or remove it. Then you need to check the compatibility of the versions of the program and the operating system, reinstall and configure in accordance with the documentation.

The problem should be solved, but if this does not happen, then it is recommended to check for virus infection on the computer, disable unnecessary programs at startup. In extreme cases, please contact technical support developer.

Device issues

Problems with components can lead to the most unpredictable consequences. The computer may begin to freeze during bootup, games, or other applications.

The main problems causing laptop freezes are most often associated with the following components:

Diagnosing the problem on your own is usually quite difficult. It is recommended to check the temperature of the processor and video card, test for errors HDD And RAM. This can be done using specialized utilities. Some information, such as CPU temperature, can be found in the BIOS.

Lots of programs in startup

A large number of applications that start with Windows can also lead to slow performance or a complete freeze of the computer. Often, users do not pay attention to the settings of the installer, as a result of which completely unnecessary software gets into autorun.

You can solve the problem by changing the application settings, using specialized utilities, or simply by removing unnecessary programs. After changing the settings, you will need to reboot.

In cases where the amount of RAM is small, it is worth thinking about upgrading. You can increase the RAM by replacing modules or, if there are free slots, by simply adding.

What needs to be done so that the laptop does not freeze

Prevention helps to effectively deal with most problems that lead to a decrease in system performance. In addition, it helps to avoid unnecessary expenses for repair and maintenance of a laptop in a service center.

Main preventive measures to maintain system performance:

• dust removal;
• removal of unnecessary applications;
• regular cleaning of directories with temporary files;
• disabling unnecessary autorun items.

Cleaning your laptop of dust and checking the operation of the cooling system can not only avoid performance degradation, but also extend the life of the computer. In some cases, due to overheating, components fail, and the system simply does not turn on. Cleaning should be done every few weeks.

Removing unnecessary applications and temporary files allows you to free up free space on your hard drive and thus improve system performance. Disabling unnecessary startup items will free up space in RAM and increase performance. You can regularly perform these actions using special utilities.

Reboot Methods

If you encounter any problems, the first thing to do is to restart your computer. This allows the system to start from the beginning and possibly avoid errors. Also, a reboot will be required to run diagnostic tools, some antivirus utilities, and enter Safe Mode.

Consider the main ways to restart a laptop running Windows:

1. program;
2. mechanical.

Program

The most convenient way to perform a reboot is software. It allows you to avoid accidental data loss, as well as save all changes made to the Windows configuration. Microsoft, when designing its operating system, has provided many ways to manage power and reboot.

Consider the main options to restart the laptop from Windows:

• through the Start panel;
• using the task manager;
• using the command line.

Through the start panel

The classic reboot method is to select Shut Down from the Start menu. In the window that appears, the user is given several actions to choose from: restarting, shutting down and putting the computer into sleep or hibernation mode.

Through the task manager

The task manager built into the operating system also allows you to shut down your work.

enough to start it:

Through the command line

The Windows command line allows you to perform most of the functions available from the graphical interface.

First of all, it is necessary:

• open the command line using the appropriate item on the Start menu or by pressing the Win + R combination;
• by entering the cmd command in the window that appears:

Mechanical

There are times when the laptop does not turn off programmatically and you have to resort to mechanical actions.

The main ways to turn off the laptop hardware:

• using the "Power" button;
• disconnecting the battery.

Through the power button

The Power button turns on the computer, and you can force the power off by holding it down for a few seconds. In this case, the laptop will turn off.

Disconnecting the battery

It is rare to resort to disconnecting the battery, only in cases where the computer is frozen so that it does not respond to the keyboard and holding the power button. It is necessary to disconnect the laptop from the network, and then remove the battery for a few seconds.

Most laptop freezing errors can be resolved by the user. If the reasons are of a hardware nature or it is not possible to identify them, it is recommended to contact a specialized service center.

By and large, a laptop is the same computer as a stationary one, but at the same time there are a number of features in its operation that everyone should know. For example, if the computer freezes, it is easy to restart it: you can press the reset button on the processor, turn off the “off” button on the back of the system unit, or simply unplug the power cord. A laptop doesn't have that option.

If the laptop freezes, press the “Ctrl” + “Alt” + “Delete” keys at the same time. The Windows Task Manager window will appear on the screen, in which the “Applications” tab will display information on all those running on this moment programs. If one or more of them says “Not responding”, mark it with the left mouse button and click the “End task” button. Wait for some time for the operating system to come to its senses, and you can continue working. If using the “Task Manager” did not solve the problem, press the power button, hold it until the laptop turns off. This usually only takes a few seconds. If the laptop does not respond in any way to pressing the power button, do not think that you can solve the problem by unplugging the power cord. The laptop will simply switch to battery power. Therefore, you need to disconnect the battery itself. Unplug the power cord, close the laptop cover, turn the device upside down, disconnect the battery from the laptop case by simply moving the special latch. By disabling access to the battery in this way for a few seconds, you will definitely achieve a shutdown of the laptop.

Remember that with any forced shutdown of the laptop, some unsaved data may disappear without a trace, so try to save the processed information more often.

If your laptop refuses to turn on, then there may be several reasons. But first you need to define the concept of "does not turn on." If when you press (or hold down the power button) while the charger is connected, the laptop does not start, that is, the fan does not turn on, the screen remains black, then this means that the laptop does not turn on. In other cases, for example, when the screen remains black and you hear the noise of a running fan, your laptop has turned on, but there are other problems with displaying the image, etc. We will consider both options.

The laptop does not turn on and does not show signs of life

Let's say that the laptop does not react in any way to being turned on. Why is this happening and what to do in this case? First you need to make sure that the power supply system is working. Usually, there is an LED charge indicator at the place where the charger is connected. If the indicator is on, then the power is most likely being supplied to the device normally. If you do not have a power indicator or it is not lit, then you need to make sure that the charger is working, for example, by connecting it to another laptop or by measuring the voltage on the connected plug. In the latter case, you will need a special device - a multimeter, which you must be able to use. Certainly, the best option is to connect a guaranteed working "charger" tested on other computers.

After eliminating the charger from the list of possible causes of a malfunction, you should check the battery. Often, due to its malfunction, the laptop does not turn on even when the power source is connected. Remove the battery from the laptop, press and hold the power button for one minute. In this case, the charger should not be connected to the laptop. Without inserting the battery, connect the charger to the laptop and try turning on the laptop. If it does not start, then the power module on the motherboard may be faulty or there is a short circuit in the power circuit and even incorrect motherboard BIOS firmware. It is almost impossible to diagnose and eliminate such malfunctions without special equipment, therefore, in this case, a direct road to a laptop repair service center.

Another likely reason that the laptop does not turn on is a malfunction of the power button itself. Its contact group or supply cable may become unusable. On many laptops, the button also lights up when pressed. Therefore, if the laptop's power indicator is on and the battery is definitely working, and the button does not respond to pressing in any way, then it may be the case. In this case, you will have to contact the workshop.

Laptop turns on - black screen

If your laptop still turns on, but the screen remains black, then this indicates a malfunction in the computer hardware. Moreover, such a malfunction does not occur instantly, of course, if you did not drop the laptop or subject it to strong mechanical stress. The failure of the backlight lamp or matrix inverter is usually accompanied by screen flickering, as well as uneven backlighting. These signs already indicate that the display may soon stop working.

Other reasons may be the failure of the RAM, as an option, the incorrect installation of the memory bar into the slot. RAM must be tested with a special program, such as Memtest86+. Incorrect operation of the processor or north bridge, errors in the BIOS firmware are the reasons why the laptop can start with a black screen. Also pay attention to the CapsLock and NumLock indicators, they often start blinking in a certain way, indicating a particular hardware problem on your laptop. You can decrypt such signals on the device manufacturer's website.

If on initial stage boot screen displays some information, but then the display goes blank, then the problem is probably due to the inability to initialize the BIOS. This malfunction is caused by laptop components, in particular, the southbridge chip, the processor (in this case, reboots occur some time after the laptop is turned on). Also, the BIOS is affected by power outages, especially when the battery is dead. If the issue of overheating can be solved by replacing the cooler, then it is better to entrust the search and elimination of problems with the BIOS firmware and other hardware malfunctions to a specialized service center.

Another symptom that the user may encounter is the laptop freezing after turning on. In this case, the computer does not respond to pressing the keyboard buttons. Such cases often occur when there are problems with the hard drive or with the operating system itself. To diagnose a hard drive, you must perform a special test, for example, using the HDDScan program. Testing will check the integrity of the sectors hard drive. It is also necessary to check the correctness of its connection. The culprit may be a failed south bridge.

Software issues

This kind of problem can be attributed to the category “laptop does not turn on” with a stretch, since, in fact, the computer starts up, but there are questions about the installed software. This is a separate big topic. But still, let's briefly go over the possible symptoms and ways to solve problems.

If the reason lies in the software area, then the first thing to try is to start the operating system in safe mode. Usually, to do this, before starting to boot Windows, you must press F8 and select a boot option from the proposed list. Click "Safe Mode". If in this mode the laptop starts up normally and no freezes occur, then you should check the computer for viruses. Also, if you installed any software, especially drivers, before the problems appeared, then they must be removed.

If after all the manipulations in normal mode If the download still hangs or reboots, then you need to check the integrity of the operating system files. To do this, you need to install a disk with the original OS image into the drive and run the SFC /SCANNOW command on the command line. Based on the results of the scan, damaged files will be automatically restored. system files.

The cardinal and latest solution to problems with the operating system will be its complete reinstallation. Do not forget to make a backup copy of important files stored on the system drive.

As a rule, most laptop hardware problems are best diagnosed and repaired in service centers. But experienced users are quite capable of dealing with software errors.

Surely, many laptop owners have encountered such a problem when the laptop freezes when turned on. The reasons why this happens are different, for example, a failure in the software part of the system or a technical breakdown. In today's article, we will look at the most common causes that lead to freezing, and also tell you how you can deal with them.

Dust and Dirt

The first most common reason why a laptop freezes when turned on is too much dust and debris building up inside the case. Many users mistakenly believe that laptops do not suffer from pollution, but this is not at all the case. Dust gets inside at every moment convenient for it, gradually it becomes more and more. As a result, the motherboard starts to overheat, the cooling system cannot cope with the load, and the laptop simply freezes after strong brakes.

Troubleshooting is generally easy. It is enough to arm yourself with a screwdriver of the right size and disassemble the laptop to make a complete cleaning of dust. If there is a fear that something will be broken or damaged during the disassembly process, then the laptop can be given to the nearest computer service, where experienced people will quickly disassemble it, clean it and assemble it back.

Bad RAM

The second reason why the laptop freezes when turned on is a faulty RAM module. This happens very often, and there is no way to warn against this breakdown. The fact is that when assembling a laptop at the factory, the manufacturer buys RAM in advance from a certain company. The cheaper the device, the more likely it is to have a memory bar from some mediocre company.

But not only this can cause a malfunction of the RAM. There is also such a thing as marriage. Even for trusted DDR manufacturers, some kind of failure may occur during the manufacture of RAM sticks, as a result of which the entire batch will be defective.

The problem is eliminated by simply replacing the faulty module with a new one, but before doing this, you need to make sure that the problem is in the RAM. To do this, remove the bottom plastic cover that covers the memory slots. Next, you should remove the DDR bar, insert another module in its place and try to turn on the laptop. If two RAM strips are installed, then you need to remove them one by one, because only 1 module can be faulty.

In general, it is still difficult to diagnose a RAM malfunction at home, since you need to have not only an extra memory bar on hand, but also a second laptop, so it is best to take the device to a repair service.

HDD failure

Another fairly common reason why a laptop freezes when turned on is a hard drive failure. Sometimes the HDD can fail completely unnoticed by the user. For example, the laptop worked all day, it was turned off at night, and in the morning it died. Why this happens is hard to say. This can be facilitated by overheating, the constant workload of the disk with many processes in the system, a manufacturing defect, or simply a poor-quality product.

Diagnosing a hard drive for a malfunction is quite easy. As a rule, if the laptop hangs on the company logo splash screen after turning it on, and nothing happens after that, then with a high degree of probability the problem is in the HDD. In order to be sure of this for sure, you need to try starting the laptop in safe mode. If nothing happens, then the diagnosis is correct.

Also, for diagnostics, you can remove the HDD from the laptop and connect it to the motherboard on a desktop computer. If it is not detected in the system or it cannot be opened through the conductor, then you can safely write off the component for replacement.

System failure

A failure in the operating system also often leads to the fact that the laptop freezes after being turned on. Failures are usually caused by incorrect shutdowns, sudden reboots, accidental deletion of the necessary file, “crooked” Windows updates, etc.

You can fix this problem by using System Restore via safe mode or the original Windows image on disk. Below is detailed video about how this can be done.

viral infection

Virus infection also often leads to the fact that the laptop freezes when turned on. What to do in this case? Fight viruses and eliminate them. The easiest way is to restore the system through safe mode. If this does not help, then it is definitely worth using a special set of utilities that work from under DOS. One of the best is Dr. Web LiveCD. All you need to do is download the utility from the official website, then, following the instructions, write it to a USB flash drive or disk, then insert it into the drive or USB port of your laptop and run it.

Static electricity

Static electricity can also cause freezes. For example, you can often meet users on the network who complain that their Lenovo laptops freeze when turned on. This problem is especially common on the 500th series of laptops from this manufacturer. What's happening? The laptop freezes tightly on the Lenovo splash screen and does not want to boot any further.

You can fix the problem as follows. You need to remove the battery, and then press the power button and hold it for 1 minute. After that, the battery can be inserted back and the device turned on. In some cases, in addition to the battery, you also have to remove the bottom cover and additionally disconnect the hard drive and drive.

Usually, users are faced with the problem of laptop operation when it is less common for users, on the contrary, the laptop stops turning off. After you click "Shutdown", all programs may be terminated, but the laptop continues to work. Another behavior is also possible, when the laptop screen goes blank, and the noise of the running fans indicates that the device has not turned off. Consider the possible reasons for this laptop behavior and how you can get rid of such problems.

Reasons for freezing on shutdown

Most often, the problem with turning off the laptop is a program conflict or too many running applications. If during shutdown you have running big number programs, they will be completed one by one by the system, saving the necessary data. Therefore, the shutdown process can be quite lengthy in this case. At the same time, some applications can actively work with the system, which often leads to a conflict and the system fails to terminate such an application.

A malfunction of the system can bring and.
Viruses are able to infect system files and block system activities, including the completion of these processes when the laptop is turned off.

Also, a problem with turning off the computer may occur after updating the operating system or. So, after updating the system, conflicts with old applications or drivers may occur, which leads to malfunctions and system freezes. Incorrectly installed drivers cause laptop devices to malfunction, resulting in crashes when the laptop is turned off.

There are frequent cases when, due to overheating of laptop components, problems arise in the operation of both the device itself (constant freezes) and when the device is turned off, which lasts for a very long time.

How to turn off a frozen laptop

If your laptop freezes at the shutdown stage, then you can turn it off in several ways. The first, most radical way -> disconnect the power supply cord and pull the battery out of the compartment. Turning off the laptop in this way is highly discouraged, as hard disk damage and, in some cases, data loss are possible.

The next one is simpler, but no less destructive - pressing and holding the power button for a few seconds. After a few seconds, the laptop will turn off, but such a shutdown will not be correct.

To configure a softer shutdown, you need to open the USB Controllers section in the list, where for each device named USB Root Hub, check the box in the properties on the Power Management tab next to the option "Allow the computer to turn off this device to save power".

If the laptop stopped turning off correctly after a recent system update or after installing the program, and before that it worked properly, then it makes sense to use. We go to the "Start" menu, enter the search line "System Restore" and run the found utility. In the System Restore Wizard, you will need to select an earlier restore point when the laptop was stable. After that, the wizard will start and the system will be restored to the previous state.

Optimization of free space and processes

Next, you should clean the laptop, freeing up the disk space of the system disk from temporary and unnecessary files. You should uninstall unused applications, excluding regularly unused service utilities and applications from it. After that, you should check the hard drive for viruses and other malicious software. I recommend an excellent utility for cleaning up space and autoloading - CCleaner.

It is also worth cleaning the laptop from dust, and in some cases (with intense heating), replace the thermal paste. Only after performing such procedures, the laptop usually starts to work more stably and shutdown problems may no longer be observed.
