The computer restarts by itself. The computer keeps rebooting: what should I do? The computer constantly reboots at startup, what should I do?

The problem of the computer constantly restarting when turned on is not new to users. Each of them is then lost in conjecture, trying to find the cause of the failure. This article will help you figure this out.

Overheat

A fairly common reason for a device to restart continuously is its overheating. This phenomenon does not pose a particular danger to the system, although it occurs quite often. If you don't take proper care of your computer, it can become clogged. Or rather, it will simply become clogged with dust. But this problem is not critical, but can be easily fixed.

Also, the cause of continuous rebooting of the device may be damaged thermal paste, which is a viscous mass intended for thermal exchange. In addition, overheating can cause the computer to be near the battery or windows on the sunny side. True, there are other reasons that lead to constant rebooting of the device.

Nutrition

The power supply may be damaged or simply broken. This is another reason why your computer keeps rebooting when you turn it on. Here, problems may be due to insufficient power to start the system. Power supplies break down, as a rule, for two main reasons:

1. Burnout of microcircuits.
2. Clogged with dust.

Cheap block options often suffer from chip burnout. Therefore, this problem is not new for users who decide to save on their purchase. If you do not carry out timely cleaning, and also do not monitor the condition of the device, its components quickly fail.

Equipment

The problem that causes your computer to keep restarting could be its hardware. In other words, incompatibility of components, failures and malfunctions. If a new RAM, video card, motherboard, hard drive or any other component was recently installed, it is recommended to disable it and see what the result is.

Typically, the user should hear a characteristic sound that indicates that a certain computer part is missing. It is worth noting that incompatibility is usually observed in the hard drive. If this is indeed the case, it is worth replacing it.

BIOS and contacts

Also, constant device restarts are often accompanied by various problems in the BIOS system, as well as bad or damaged contacts. To establish the cause of the failures, you will need the help of a good specialist. Fortunately, today there are enough of them. The most common problem with a computer constantly restarting when turned on is computer viruses. If failures occur due to poor contacts, everything is much worse. It is sometimes difficult to identify such malfunctions.

For this, correct diagnostics is necessary, otherwise you should not even dream of resuming the usual operation of the system. It is not advisable to fix problems yourself, as this can cause even more damage to your computer. However, it happens that the device constantly reboots, and a blue screen appears before the system goes to restart.

Blue screen

This problem is common for most users. It indicates problems with drivers or the device itself. Thus, if the computer constantly restarts when turned on and a blue screen appears, there is no reason to panic. If you look closely at the image, you can see many “curious” lines. They explain the reason for the “screen of death”. Of course, it will not be described verbatim to the user verbatim.

But an experienced user will easily understand the current situation. An error code will appear on the screen, as well as the address of the “damaged file”. To read the text, you need to hold down F8 during the next restart and disable the reboot in automatic mode. After this, you can easily read the writing on the screen and even rewrite it.

What to do if your computer overheats?

If the reason for the device constantly rebooting when turned on is overheating, you must use methods to correct this situation. When working with a laptop, it is recommended to purchase a special stand for it. It will promote improved air circulation and prevent the retention of warm masses inside the device.

In the case of desktop computers, such stands are not provided. Considering the design features of the “iron friend”, it is not possible to use them. In this situation, it is suggested to move the computer away from the wall, as well as any other enclosed space. In addition, you can remove the side panel located on the system unit. After this, it is advisable to regularly clean the equipment from dust. As for laptops, it is better to take them to service centers to carry out a similar procedure. A personal computer intended for home use can be cleaned yourself.

For this you will need:

- dry cloths;
- vacuum cleaner;
- brushes.

Once the device is provided with proper care and good ventilation, the problem will disappear on its own.

Lack of power

At the first sign of such problems, you need to check the power supply. This has already been discussed above. Cheap equipment is prone to frequent breakdowns. In this case, it is recommended to urgently take the computer for repair. Specialists will be able to identify the problem and suggest ways to solve it. If it is determined that the reason for the system constantly restarting is a faulty power supply, there is no need to be upset. It's better to go to the store and buy what you can afford. It is advisable to buy a high-quality power supply to ensure stable operation of the device.

If the equipment is not suitable

In case of incompatibility of equipment with the device, the problem can be completely solved. However, it can also cause various problems associated with continuous restarting of the computer. This can be solved very simply, especially if there is a good hardware store nearby. First you need to determine what exactly does not fit. Then you need to turn off the equipment. When the cause is identified, it is enough to simply replace the part that interfered with the work with a new one.

You should choose a component that will not cause compatibility problems. If the contacts on the motherboard or any other spare part are damaged, they will need to be fixed. They may not be repairable. In this case, parts will need to be replaced. The main thing to remember is that you should not fix the problem yourself without having the specific knowledge to do so. This can only harm the device. It is better to use the services of specialists.

Fighting blue screen

If a user is faced with the problem of constantly restarting the computer and the appearance of a blue screen of death, he begins to think about solving it. It is advisable to take it as soon as possible. First, it is recommended to determine the cause of the breakdown.

It is worth noting software and hardware types of problems. First of all, you need to disable automatic computer restart. Such actions have already been described above. To do this, use the F8 key. When the error code is seen, you need to restart your computer. You don't have to be a professional to identify hardware failures.

This is quite easy to do. The device will produce blue screens even after installing a Live CD intended for system recovery. In this case, it is recommended to look in an accessible place to see what error occurred. To do this, you can use a reference book or the Internet. Then it is worth replacing the equipment that is damaged.

If your computer keeps restarting, but the problem is software, there are several ways to solve it. The first option involves finding the breakdown and fixing it. In other words, when using operating system resuscitators, you need to connect to your own device and remove what caused the blue screen. The second option suggests restoring the system. This is done using a Live CD or Windows installer. It is worth noting that personal use data will not be affected in this case.

When software problems cannot be resolved humanely, barbaric methods must be used. We are talking about a complete reinstallation of the operating system. In this case, you will need to format the hard drive and perform the installation again. This is not the most pleasant process. In addition, it is worth spending a lot of time on it.

Reinstalling the OS is especially difficult if valuable data and files were stored on the computer. After completing this time-consuming process, the device will reboot itself 2-3 times. Do not be alarmed and interrupt the installation. It is imperative to wait until the system is ready for use. As a result, she will prompt you to enter your name, time, date, time zone, and proceed with activation. After this, all that remains is to enjoy the absence of problems.

The article explained in detail what to do if the computer continuously reboots when turned on, as well as why this happens. As you can see, there is no point in panic. With proper diagnosis, solving the problem is quite simple. The main thing is not to delay the treatment of the device and then it will delight you with stable operation.

This problem occurs quite often and is a consequence of various types of failures, both system and hardware. The problem should be fixed as soon as possible, since in the case of overheating, even the contact may melt during one of these shutdowns, which will lead to the need to go to a service center.

The computer often turns off due to overheating of the central processor, power supply or video adapter.

This is such protection, since if you pass the permissible heating point, the device will fail, and using such a fuse, the computer will simply turn off.

The next most common reason is a system reason, when an important system file is broken, installing several antiviruses can also become a problem. Sometimes even the BIOS or UEFI becomes a problem, but this is easy to diagnose. Now let's take a look at the reasons why a computer can reboot itself.

Reasons for spontaneous computer restart

In fact, there can be quite a few reasons, so you should make an initial diagnosis, noticing all the factors that cause the failure. Here you should pay attention to the following: after performing what actions the problem occurred, under what conditions, when running what function does the death window appear, at what moment. Having studied this problem, you can proceed directly to studying the causes and methods of solving them.

Restarting your computer due to system failures

1.Viral activity in the system. Quite often, various kinds of worms creep into Windows, but only a few are capable of causing such damage that a system restart occurs, and not without the participation of other factors. You should check your hard drive with antivirus software, it is better to conduct a full analysis. In order to do this, you may need to connect the hard drive to another computer, or vice versa, in order to avoid rebooting the system;

2.Software or installed drivers conflict. In the case of hardware and software that conflict with each other, it is difficult to determine the cause. The best solution would be to remember after installing which driver the problem occurred or roll back all of them one by one until the problem is resolved;

3.In case of installation several antiviruses, there is always a slowdown in the system, and in rare cases, failures that lead to spontaneous restarts. Here the solution is to start the computer in safe mode and remove one of the protection programs;

4.Crashes inBIOS. This is not a common problem, but it also occurs; it is often associated with installing new, working equipment or updating the motherboard firmware. You should update the BIOS version to the latest and most stable version or roll back the changes. To get started, you can use a factory reset, it may help;

. Typically, these programs are games, and if the reboot occurs immediately after clicking on the launch file, then you most likely lack any necessary functions.

You need to study the program requirements and install the required programming environment or use system recovery from a boot disk

6.Bad sectors on the hard drive. You can check this using many programs, for example: Victoria will allow you to view the integrity of sectors and help restore them.

We have discussed the main software reasons for this, but reboots often occur due to failures of some equipment.

Rebooting your computer due to hardware failures

1. Overheating of some element of the system, often the power supply, video card or central processor. To determine this scenario, you may notice a system reboot precisely at the moment of heavy load, usually the launch of a game, a stress test, or some resource-intensive video processors. In this option there are three subparagraphs for a more targeted solution to the problem:

• When the computer reboots under load, you should clean the system unit. If you are confident in your abilities, you can do this yourself, armed with a screwdriver and a brush;

• Cooler won't start or stalls at some stage of operation. There may also be a reason for the accumulation of dust, which prevents the cooler from working at the desired speed; in addition, you should lubricate it with synthetic oil. WD-40 is not suitable for permanent use, only as a temporary solution for a week or two, perhaps you lubricate it too often and a lot of waste has accumulated in the cooler, then you should disassemble it and clean it;

• Overheating occurs due to lack of thermal paste or its processing, of poor quality. In this case, the heat is poorly pumped out to the radiator and the device’s processor simply suffocates. Accordingly, you need to replace the thermal paste; it is better not to use the cheapest one.

2. At the time of stress, the same nutrition is required if you have installed weak power supply or yours is already outdated, there may simply not be enough power for the equipment to operate properly, usually this affects primarily USB devices that simply turn off. The solution is to replace the block or at least repair it;

3.Frequent hard drive brings problems, which may fail or simply fail. In this case, you can try changing the connector, make sure that the device has a tight horizontal fastening, no angle is allowed. You may need to replace the drive;

4.RAM conflicts, if there are any defects in the RAM or the timings do not match, then this kind of problem may arise. You will need to turn off the strips one by one and then check;

5.Bad contacts. Most likely, the computer will not start at all for this reason, but a reboot may be an option. You should check the integrity of the cables and the tightness of the contacts. Perhaps one has come off, the insulation has rubbed off or is not secured.

To summarize, we can say that the first thing to do when your computer spontaneously reboots is to clean the system unit from dust, check the functionality of the coolers and the quality of the contacts.

If you still have questions on the topic “The computer reboots itself: reasons, how to fix the problem?”, you can ask them in the comments

This problem is quite widespread. Owners of both old and fairly new computers may encounter this problem. Spontaneous computer reboots can occur due to software problems, but much more often due to hardware ones. It is quite possible to fix these problems yourself at home, while having a basic understanding of the computer structure.

In this article we will talk about possible reasons for computer reboots, as well as how you can try to fix it yourself.

Why is this happening?

Almost always, a spontaneous computer reboot means a critical system failure has occurred. It is accompanied by the appearance of a blue screen with an error code. It is also often called the “Blue Screen of Death”.

This is what the blue screen of death looks like

It’s just that the display of this screen is not always enabled in the system settings. Therefore, the first thing you need to do is turn it on to see the error code, and then look for the problem using the code.

View of a blue screen in Windows 10 with an error code that you need to look for the problem

To do this, go to the computer properties by right-clicking on the “Computer” icon on the desktop or in the start menu, and select “Properties” from the context menu.

Calling computer properties

In the window that appears, on the left, click on “Advanced system settings.”

Extra options

A new System Properties window will appear. In it, go to the “Advanced” tab and in the “Boot and Recovery” section, click the “Options...” button.

Disable computer restart during a system failure to view the error code on a blue screen

Close all open windows by clicking the “Ok” button.

By doing this, we disabled automatic reboot when the system fails in order to see a screen with an error code, which can be used to search for the problem in the future.

We present to you a list of the most likely culprits for this computer behavior:

• RAM.

Definitely takes first place in popularity. Before attempting to scan your system for viruses or reinstall Windows, check your RAM. This can be done with the program.

Window of the running memtest86+ program

Sometimes it helps to simply take out its connector memory module and install it in place.

RAM manipulation

If you have several RAM modules installed, be sure to try working with each of them separately. Since very often 1 memory module fails and because of it the computer will constantly reboot, throwing out a blue screen with a wide variety of codes.

If one memory module is installed, then it would be very good to borrow a known working module from someone and try to work on it. If reboots do not disappear, then the problem is definitely not in memory.

• Swollen capacitors

If you have problems with phantom reboots, be sure to visually check the motherboard and power supply for swollen capacitors. They look like this:

One of the reasons is a swollen capacitor

If there is at least one, then it is very likely that this is the problem and needs to be replaced (resoldered).

• Overheat

Despite the fact that due to overheating, a computer or laptop most often turns off rather than reboots, you should still pay attention to the operating temperatures of the main components of the PC, namely the processor, video card, and south bridge. The most convenient way to do this is. If something heats up above 80 degrees, then you need to solve the overheating problem (cleaning, replacing thermal paste).

• power unit

It is important to remember whether any parts were replaced in the system unit before independent reboots appeared. If you changed something to a more powerful and modern one (for example, a processor or video card), then it is possible that your power supply cannot cope with the increased load on it. Replacing the power supply with a more powerful one will solve this problem.

Replacing the power supply

If nothing has changed, then it still wouldn’t hurt to borrow a known working power supply from someone and check how the computer will behave with it.

• HDD

Unreadable or hard to read sectors on your hard drive can also cause your computer or laptop to reboot during operation. the MHDD or Victoria program will dot the i’s.

• Problems with the operating system

Despite the fact that this is one of the simplest options (many people can reinstall Windows themselves), according to statistics, in 85% of cases, reinstalling Windows does not solve problems with self-reboots. However, if rearranging the OS is not a problem for you, then you can try to do this in order to remove from the list of possible suspects viruses, driver conflicts, etc., which are talked about so much on various sites and forums.

The best way to thank the author of the article is to repost it on your page

Hi all! In this article I will try to describe why the computer reboots by itself and the most common reasons for an unexpected computer reboot.

The computer keeps rebooting - what should I do?

1. Software problems

Your computer is installing important security updates

If at any point your computer starts to reboot, pay attention to how it does it. If it reboots like you would if you clicked restart, ending your session, then the computer is likely currently installing some security updates. It should report this before and during the reboot.


Typically, most updates do not require an immediate reboot, but in some cases the opposite happens. The computer schedules a reboot and gives us time to save all important documents.
In this case, you don’t need to do anything, just wait until the updates are installed.
Do not under any circumstances unplug your computer while installing updates! This can lead to damage to the operating system.

A blue screen appears and the computer restarts

If the Blue Screen of Death appears before rebooting, pay attention to the error code at the bottom of the screen. Write it down. Please note that a blue screen may indicate hardware problems.


After this, you can see what this error means. If the information found does not clearly indicate what the problem is, you can try to re-induce the freeze. Start the computer and carefully monitor the progress of its operation, try to perform the same steps after which the computer rebooted. You can also try running a resource-intensive task, such as an antivirus scan.

If the error code has changed, this is a clear sign of damage to the internal components of the computer. In this case, you need to contact a service center specialist for repairs.

Also try to track after running which program the computer reboots. If you can establish a pattern of reboots, do not use the program that caused the failure or remove it from startup.

2. Problems with hardware

If the computer restarts instantly while running(the monitor went off and Windows started loading), this indicates problems with the hardware or software.

Power supply problem

If the screen goes out instantly without displaying any messages, there is most likely a problem with the power supply of the system unit. The first thing to do is check the power cable going to the system unit. It is possible that it is not inserted all the way. If it is inserted all the way into the power supply connector, but it “swings” a lot and sparks, it is best to replace it.

Also, the computer may restart on its own due to unstable voltage in the house. In this case, it is advisable to use . Also always choose good quality power supplies. For example, the company FSP.

Computer overheating

Broken hard drive

You can also try running a check on your hard drive for errors.
To do this, go to the “My Computer” folder. Right-click on the operating system drive (usually Local Drive C:), click Properties.

In the window that opens, go to the “Tools” tab and click “Check Disk”.

Check all the boxes and click “Ok”. The computer will warn you to restart.

Depending on the disk size, the check can last from 15 minutes to several hours. The process may vary slightly on different operating systems.

If after this check the blue screen repeats, then check the hard drive for dead pixels here, and you can try to fix it.

RAM

If after all the manipulations you cannot fix the problem, try checking.

Motherboard, BIOS, device compatibility

And finally, look carefully at the motherboard to see if there are any swollen parts or microcracks;

You can try resetting the BIOS and updating to the latest version;

I also encountered cases where there were incompatible parts with the motherboard. To find out, you need to go to the official website of your motherboard and find a list of compatible equipment. If, for example, you find that the RAM is not compatible, for example, write to the technical support of this company and report it. It is quite possible that after some time a new BIOS will appear that will be compatible with this RAM.

Of course, there can be many reasons why the computer restarts on its own. In this article, I described those actions that you can handle yourself. If the problem cannot be solved, you need to seek help from professionals.

If your computer begins to reboot immediately after turning on or a few minutes after starting work, then there may be several reasons why the computer reboots itself. It happens that the computer at the same time begins to freeze, takes a long time to load, and the like. There may be several main reasons for this problem; usually, you can solve them yourself, without resorting to the help of specialists from the service center. What to do if the computer reboots spontaneously?

The computer restarts when turned on

Once you turn on the device, after a few seconds it reboots itself. And this happens several times, the computer constantly reboots upon startup. First of all, you need to determine the cause. It can be in software or technical issues. First, let's look at the technical aspects, since they are most often the causes of problems.

Why does my computer keep rebooting by itself?:

• Overheat
• Damage to thermal paste
• Contacts are damaged
• The power supply is faulty

Below, we will consider each case and its solution.

Overheat

Three things can overheat in a computer - the main processor, the mother card and the video card. There can also be several reasons for overheating.
Due to improper operation of coolers or large accumulation of dust. To check this, open the system unit by removing the side cover.

Carefully inspect the internal parts of the computer. Typically, coolers are located on the CPU (central processing unit) and on the video card. To check their functionality, turn on your PC. If they turn slowly or make a buzzing noise, they will need to be replaced. But sometimes it is enough to thoroughly wipe all the internal parts from the dust that has accumulated there. To do this, you can carefully vacuum all parts of the computer. For small details, use a brush.

Do everything carefully - processor parts may be damaged by static voltage. Alternatively, wipe everything down with a damp, lint-free cloth. The cooler must be carefully removed, disassembled, removed dust and lubricated with a thin layer of machine oil. It’s also better to remove the video card, unscrew the fans with a screwdriver, and wipe everything thoroughly.

Damaged thermal paste

Thermal paste ensures optimal heat transfer between the internal parts of the computer. If it dries out, heat transfer is disrupted and the computer overheats. Thermal paste is sold in specialized stores. It's easy to replace it yourself. There are many training videos on the Internet with a detailed process of replacing thermal paste.

Overheating may be caused by a lack of external air exchange. If the system unit is located next to a radiator, is exposed to direct sunlight, or is built into a table, try moving it to another location. This may solve the overheating problem. Overheating often occurs during the hot season.

Faulty power supply

An outdated and dusty network unit may cause the computer to constantly reboot. Dry thermal paste or a low-quality motherboard can lead to periodic voltage drops. Because of this, the computer spontaneously reboots after a short period of operation. The problem can be solved by replacing the unit with a more powerful analogue.

Bad contacts

The problem may be with loose contacts. Carefully disconnect and connect one by one all externally visible connectors.
These are the main technical points why the computer reboots itself, but there are also cases when everything is fine from the technical side, the problem is in the software.

Why does the computer restart while playing?

If the computer is working normally, but a reboot occurs while the game is starting, there are several options.

• The game may be too "heavy" for the computer.
• You have contracted a harmful virus.
• Your video card is damaged or you need to update the drivers

The computer may overheat when starting a game that is “heavy” for your system, and automatically reboot. The reason is weak coolers or a low-power power supply. As a rule, a heavy game on a weak computer will not start or will be very slow, but it may be that the characteristics of your PC meet the requirements of the game and your video card runs the game without freezing, but the power supply cannot cope with the power consumption of the video card when the video processor is actively working . If this happens to all games, try reinstalling the drivers on the video card or cleaning the system from viruses.

How to reinstall drivers on a video card

The computer reboots itself from Windows 7, 10

The computer constantly restarts when starting Windows 7 or 10. This problem has one solution for both OS.
Windows 10 and 7 may reboot spontaneously after updating. There may be a continuous update feature installed, which can be deactivated and adjusted to personal preference.
First, sign in to Windows Update. Click Win+R, enter gpedit.msc in the line that appears, press “Enter”.

We are walking along the path - “Administrative Templates\Windows Components\Windows Update”.

We change two options. First "Do not automatically reboot when installing updates automatically if there are users running on the system". Double-click with the mouse. Put a tick on "Turn on" and press "OK". Next: you need to deactivate the item "Always automatically reboot at the specified time". We also double-click on the parameter and in the pop-up window, check the box "Disable".


After all the manipulations, you need to restart the computer. After this, the problem with Windows 10 or Windows 7 automatically restarting will no longer bother you.
