The laptop receives power but does not turn on. What to do if the laptop does not turn on. Other reasons for the laptop not turning on - video
Sometimes there is such a problem that your laptop stops working and you cannot understand what is the reason. Well, this is quite unpleasant. Especially if your laptop serves as a workstation. In this article we will tell you what troubles could happen to your laptop.
Different problems may concern two areas: hardware And software. Hardware problems are when any part of the laptop fails. Software problems are problems that affect the software part of the system. For example, incorrect BIOS, OS or utilities settings.
First, you need to understand which area your problem falls into. For example, if your laptop won't even start, then the problem is definitely a hardware issue. However, if your unit can get to the BIOS or even before the operating system starts, then there is a possibility that the problem is of a software nature.
Here we need to perform a power test. Connect the power supply to the laptop and be sure to check your outlet. There should be a small diode on your device, which indicates that it is connected to the network or the battery is starting to charge.
It is possible that the problem lies in the power supply, damaged connectors or wires. Check this entire system thoroughly. In order to prevent various breakdowns, try to first power up the laptop and then plug it into a power outlet.
However, if you are convinced and sure that the problem is not in your power supply, then perhaps it is in the batteries. Reconnect the battery. You can also try turning it off external devices. After that, turn on your laptop and gradually turn on the disabled things. This will make it possible to determine what the problem is.
Loud noise from the cooler, but the screen shows no signs of life
There is a possibility that your monitor's backlight has simply stopped working. Try activating it with a key combination Fn+F2. If it doesn’t help, then you can add another monitor to the laptop. Using it, you can determine whether the problem is a non-working screen.
Other possible problem- this is a video card. Quite often we forget to do such basic things as cleaning our laptop. If you are a fairly inexperienced user and have only recently begun to get acquainted with such a thing as a laptop, then know that it needs to be cleaned regularly. Also be sure to monitor the temperature.
There are, of course, more serious problems. For example, problems with central processor, RAM, BIOS, etc.
Starts up, displays a splash screen or displays a message and freezes
The root of this problem is most likely the BIOS, or more precisely, its settings. Try to set the settings to default. This function in different BIOSes it may be in various places, but its name usually looks something like this - Load BIOS Defaults.
It is also possible that when loading the system you saw the message “Press F1 to continue”. This problem usually occurs when the battery on the motherboard (not the main battery) is installed wrong time or the BIOS settings are lost. To change the battery, you must contact a service center.
Another problem may be with the hard drive. Define correct work Winchester perhaps by its sound. When starting up, the hard drive makes a couple of crackling noises, but when everything is not in order with it, there are many more crackling noises and everything freezes.
There is also a problem with RAM. If possible, disconnect the RAM and clean its contacts. If you have more than one strip, then try disabling one of them.
Constant reboots or shutdowns
Most likely this is a hardware problem. Most likely there is a short circuit that overheats the south bridge. In most cases, this occurs due to a breakdown via USB.
Let's look at the main reasons why your laptop won't turn on and what you can do now.
It should be immediately clarified that there can be a lot of reasons for failure and they will be of both hardware and software nature. We will check everything in order and look for our case. If anything, contact a workshop in your city.
This article is suitable for all brands that produce laptops on Windows 10/8/7: ASUS, Acer, Lenovo, HP, Dell, MSI, Toshiba, Samsung and others. We are not responsible for your actions.
Attention! You can ask your question to a specialist at the end of the article.
The laptop does not turn on and shows no signs of life
Often such problems are related to nutrition. The first thing you need to do is connect the laptop to the power supply to check for voltage in the outlet. The adapters are equipped with a power light, which indicates its functionality. The laptop has a light that lights up when it is plugged in or the battery is charging.
Most often, the reason is a power supply that does not work or is not functioning properly (here you need to try a similar working one), due to the presence of bad contacts in the connectors, kinked or broken wires. Therefore, we look and draw conclusions at what stage the voltage disappears.
To avoid problems with the power connector, it is recommended to first insert the power plug into the laptop, and then only the power cord into the outlet. This will eliminate the possibility of a short-term spark occurring when connecting the plug, which could damage the contacts.
If the laptop does not turn on, but everything is “on”, then the problem may not only lie in the power supply. You should remove the battery and connect the device again without it, then after 10 minutes put the battery back. Also turn off all external connected devices, you can also turn off wifi adapter, if the design allows.
If everything works, then return the devices one by one. This is how the reason is determined.
Hard drive is faulty
In case of malfunction hard drive The laptop can be turned on, but before displaying Windows screensavers it freezes. In some cases, a message about a HDD error is displayed, for example, information that the disk is not a system one.
In any case, the user still has the opportunity to enter the BIOS. There you can check whether the settings are correct and whether the hard drive is detected. If HDD is visible, then the system can be started with bootable flash drive or disk for testing it.
Damage to chipset and video card chips
Various laptop components can fail. The causes of failure may be damage due to impact, overheating, etc.
The most common problems that arise when turning on a laptop are:
- Video card.
- North Bridge.
- South Bridge.
When a laptop breaks down, its behavior may vary. If the video card fails, then there is no picture, but the fan will function and Windows may even boot, making appropriate sounds. If one of the bridges breaks, the device will stop before loading the OS or will not turn on at all.
In this case, it is almost impossible to determine the cause yourself. At home, attempting repairs may damage the device, so it is better to contact service center.
Other reasons
In practice, a malfunction can occur in a number of cases:
- A mistake in Windows work.
- Overheat.
- Broken BIOS firmware.
- Damage to memory or processor.
If the laptop beeps when turned on, this indicates problems with the RAM or overheating. If you have a little experience, you can independently identify the problems and why this happened.
First you need to remove the dust. If the failure remains, then the memory modules should be replaced with known good ones.
The problem with broken BIOS firmware appears after incorrect update. Errors often occur during BIOS configuration. This problem It's quite easy to decide on your own. You should go to the SETUP menu, load the default settings, for example, select the Load Setup Defaults function.
Errors may appear in Windows, resulting in the operating system not starting. It is necessary to determine their cause and solve the problem. Alternatively, you can reinstall the OS or restore the installed one.
Often the laptop does not start due to power problems. After pressing the power button, the power button lights up, but then nothing happens. The cause must be found and eliminated.
The laptop stops turning on due to the following typical actions:
- Update.
- Cleaning from dust.
To troubleshoot problems, you can replace the battery:
After cleaning
After cleaning, the laptop may not turn on. In this case, the fan may start or make a squeaking noise. The indicators may flash on some models.
The process of cleaning a laptop involves disassembling it. First, you need to re-disassemble the device and check the connection of all components and the installation of the cooling system. It is important to pay attention to the thermal paste.
If RAM modules were removed during cleaning, you must try to remove them again, clean the contacts and reinstall them. It is important to check whether the laptop starts when it is turned off. optical drive and hard drive.
When disassembling again, you need to pay attention to the lid opening sensor. If the assembly is not carried out very carefully, then it may not be in the right place.
If the above tips do not help, then you should turn to professionals. There is a possibility that parts were damaged by static electricity during disassembly or another problem occurred.
After update
When updating, problems may occur. When updates are installed incorrectly, the laptop stops turning on. The user can then set new version drivers, BIOS or OS patches.
The most difficult case is the inability to start the device after updating the BIOS. This happens when the user interferes with the process, for example, by turning off or restarting the computer while updating or using unofficial firmware.
It wouldn't hurt to reset the settings to default. To do this, you need to remove the battery for a few minutes or short circuit system board corresponding jumper. In practice, this is not always possible to resolve the problem.
If the problem started after Windows updates or drivers, you should simply roll back to the previous restore point using safe mode. Restoring the operating system or returning to the state may also help, if the model supports such a function.
After overheating
Modern laptops generate a lot of heat during operation. If the cooling system is faulty or there is heavy dust, overheating occurs, which can cause some parts to break.
The following parts may fail due to overheating:
- South and north bridges.
- HDD.
- Video card.
- CPU.
Spontaneous shutdowns
In some situations, the laptop may turn on and function normally for a while. Then it happens spontaneous shutdown. Main causes of failure:
- Faulty parts.
- Software errors.
- Overheat.
The most common cause of laptop shutdowns is overheating, which can further lead to damage to the product. To avoid this, you should regularly remove dust and change the thermal conductive paste.
Quite often, parts malfunction due to overheating. If you do not carry out regular cleanings, this probability increases significantly.
Viruses can harm the correct operation of the system. As a result, the device will turn itself off. You can solve the issue using a special utility from the Kaspersky Lab website or Doctor Web, performing a full scan and removing threats.
For software errors, you need to find the cause using the code that is displayed on the screen at the time of the failure. Then problematic application need to be removed or updated.
Cannot start from boot device
When loading Windows on English language different messages may be displayed, for example, “Error loading operating system" The first step is to remove the disk from the drive, all flash drives and reboot the device. If this does not solve the issue, then the reason is a software problem with the hard drive or a hardware problem.
The most affordable method of restoring functionality would be reinstalling Windows. If this helped, then the reason was at the software level.
Another possible option is when it starts Windows download, but then the laptop reboots itself, showing errors on a blue or black screen. Here, hardware or software failures may also be the cause.
The surest way to check this is to reinstall the OS. An easy way to check is to start the system from a bootable USB flash drive. If the device does not start, then it should be taken in for repair.
Wherein. Why is this happening? What should you pay attention to? What might it take to correct the situation? Understanding the issues posed is not as easy as it seems. After all, a computer is unpredictable equipment. Problems, especially when turning on, can be the result of many failures. Some go straight to service centers. It is not recommended to do this. It is advisable to first try to diagnose the problem yourself. Maybe it will work out without outside help cope with the situation.
Video card
The power light is on but the laptop won't turn on? The reasons for this phenomenon are different. The first thing you might think is a problem with the video card. In the case of desktop computer It is easy to detect and correct a breakdown or failure - just remove this component and connect it to another machine.
But in the case of laptops you will have to try. It is recommended that if you suspect a breakdown or malfunction of the video card, contact service centers for help. Or call someone system administrator. You can also try to diagnose the problem yourself. Usually the laptop turns on by itself - you can hear the cooler running. But there is no picture on the screen. Sometimes you can even hear the operating system loading.
Screen fault
What's next? The power indicator is on, the laptop does not turn on, but can it be ruled out? It is likely that the device's monitor is broken or damaged. An extremely rare phenomenon that still occurs in practice.
If the display breaks, then most likely the “symptoms” of the breakdown will be exactly the same as in the case of the video card. There will be no image on the monitor, but the sound of the operating system turning on will appear.
You will not be able to solve this problem on your own. If only by purchasing a new laptop. In such circumstances, you can contact the service center. Maybe the display can be repaired. But usually devices do not work for long after such repairs. Ultimately, you will still have to replace the laptop with a new one.
"BIOS"
The following situation can be corrected without outside help. The power light is on but the laptop won't turn on? The main reasons for this phenomenon are either a failure or a reset.
It is likely that the BIOS settings have gone wrong. Because of this, the laptop encountered the problem under investigation. In this situation, it is recommended to completely reset the BIOS. After this, the computer should work at full capacity.
Lack of components
What else could be a consequence of this problem? If we're talking about about a new laptop that did not work before, you should not exclude the absence of any components. If the machine turns on by itself, but nothing is displayed on the screen, and the CapsLock and NumLock buttons do not go out, most likely the BIOS is not initializing.
It is likely that the laptop does not have a processor or random access memory. Or, when it comes to a previously functioning device, the reason may lie in the breakdown of the listed components.
HDD
Sometimes it happens that although the power indicator is on, the laptop does not turn on, but it previously worked normally, the hard drive becomes the cause of the problem. A small failure and the computer will refuse to start. But the power button will light up. You can also notice the fan operating normally. The "Nam Lok" and other buttons light up and go out as expected.
It is recommended to disassemble the laptop and disconnect the hard drive. In this state, try again to turn on the device. Did not help? Then you can carefully reattach the component. If the problem was a glitch, it will now disappear.
Battery
The power light is on but the laptop won't turn on? Diagnosing an incident requires certain knowledge from the user. Yes, you should not immediately send your computer for repair. But it should be taken into account that most problems are usually solved with the help of a professional.
You can resolve the situation yourself if, for example, the problem lies in the battery. It is likely that it was discharged. Then it is enough to connect the power (wire) to the network and to the machine. Next, try to turn on the device again. It's best to wait a few minutes before pressing the laptop's power button. Allow the battery to gain some charge. This technique turns out to be quite effective.
Some recommend removing the battery from the laptop completely and then connecting the power cord. Only then turn on the computer and monitor the situation. If the machine is working at full capacity, then nothing else needs to be done. Otherwise, you will have to look for the source of the problem elsewhere.
As practice shows, battery problems or a discharged laptop are common occurrences. Perhaps the safest and easily removable without outside help.
Closures
Samsung laptop won't turn on? The power indicator is on, is the cooler working? The next scenario is one of the rarest. And it is almost impossible to diagnose it yourself.
The problem under study can appear when the south or north bridge in the laptop is damaged. Why does this happen? Bridge problems are caused by different methods. For example, through a short circuit due to a temperature difference. If, say, the USB port on a laptop is damaged due to this, it is likely that the problem under study will occur.
There is only one method of struggle - repairing damaged components. Most effective way is buying a new computer. After all, laptops rarely have refurbished components. for a long time then they work. Here, each user independently decides what to do.
Viruses
If the laptop does not turn on (the power indicator is on) after the device has been functioning for some time, you should think about the impact of viruses on the machine. A computer infection often causes the computer to stop working normally. Sometimes the BIOS gets damaged by viruses. Accordingly, there will be a problem with turning on the laptop.
It is unlikely that you will be able to fix the problem yourself. As in most of the previously mentioned cases, it is better to take the computer to a service center. They will not only help you restore your laptop to working order, but will also treat it for viruses.
Fortunately, this scenario is quite rare. But it should not be excluded. Especially if the user himself admits the presence of viruses on the computer. Sometimes problems turning on a laptop arise after the operating system has been treated. Then it is enough to reinstall the BIOS first, then the OS. Afterwards, no problems will bother you anymore.
Instead of a conclusion
What conclusions can be drawn? It should be noted that in most cases, both diagnostics and troubleshooting come down to contacting a service center. Most often, this is what many people do. After all, a laptop is an extremely complex device. Repairing it yourself is not as easy as its stationary counterpart.
If you figure out why it didn’t work out, you can immediately contact specialized centers. If you suspect a specific problem, you must inform the service employees about it.
Laptops have become an integral part of life. modern man. Like other equipment, they sometimes break down. When it stops turning on, you should not panic, but you should find the cause and eliminate it. In most cases, you will be able to restore your computer's functionality.
Causes of malfunction and their solutions
There can be a huge number of reasons why the laptop does not actually turn on. Many of them are quite simple and it won’t be difficult to fix them yourself, but with some problems you will have to contact a service center.
Let's look at the main reasons why mobile computer may stop running:
Comment. Very often, when people say that the PC does not turn on at all, they mean that Windows does not load. This is not entirely correct reasoning, but it is popular among ordinary users.
Eating problems
Power-related problems very often lead to a PC that stops starting. Even though the problem seems serious, in most cases it is quite easy to diagnose and fix it at home.
Main problems related to nutrition:
- incorrect adapter connection;
- damage to cables and connectors;
- battery failure;
- power supply failure;
- problems in the power circuit.
Often, with such problems, the laptop power indicator does not light up. First of all, you should check that the power supply is connected correctly and that it is plugged into the outlet. It is worth noting that even very experienced users may forget to connect their PC to the network. As a result, after the battery is discharged, the device stops starting.
Damage to power cables and connectors can be caused by many reasons, including careless handling or pets chewing the wire. This malfunction can be verified by external inspection.
Another very common problem is related to the battery. In some cases, if it does not work, the PC stops turning on even with the network adapter. Usually, after pressing the power button, even the cooler does not work. Therefore, it is worth trying to run a mobile computer powered from the mains without a battery.
The power supply fails quite often in any device. Without a charger, the laptop battery will run out sooner or later, after which the computer will stop turning on. It's very easy to check if the network adapter is working. Just connect another Charger from a known good computer.
Many power supplies are equipped with an indicator. Even if the light is on, it is impossible to completely rule out problems with the network adapter. It is worth noting that there are many power supplies for laptops. You should only connect to your computer those that are suitable for specific model adapters.
Problems associated with a malfunction in the power circuit are much less common, but they are more serious. In this case, you will not be able to diagnose the problem yourself, much less fix it. You need to contact specialists from our service center. Leave a request and they will call you back within a few minutes.
Hard drive is faulty
The hard drive stores all the information and operating system of the computer. If it malfunctions, the computer can be turned on, but it freezes before the Windows screen saver appears. In some cases, an HDD error message may be displayed, for example, information that the disk is not the system one.
In any case, the user still has the opportunity to log into BIOS menu SETUP. There you can check whether the hard drive is detected and the settings are correct. If the hard drive is visible, then you can start the system with boot disk or flash drive and test it.
Failure of the video card and chipset chips
Laptop components may also fail. The reasons for this may be overheating, damage due to impact, and so on.
Let's look at what parts most often create problems with turning on a PC:
- south bridge;
- north bridge;
- video card.
The behavior of the computer in this case can be very different. If the video card fails, there will be no image, but the fan will work and sometimes Windows will even boot, making a corresponding sound. If one of the bridges fails, the computer may not turn on at all or may stop before loading the OS.
It is almost impossible to determine the reason in this case on your own. And trying to repair it at home will most likely only cause harm. Therefore, it is better to use the services of a service center.

Other reasons
In fact, the malfunction may lie in a number of other problems. Among which are the following:
- CPU or memory damage;
- broken BIOS firmware;
- overheat;
- errors in Windows work.
If your PC beeps when you turn it on, in most cases this indicates overheating or problems with the RAM. If you have a little experience, you can try to find out on your own why this is happening.
To do this, you must first remove the dust. If the problem persists, you can replace the memory modules with known good ones.
Broken BIOS firmware may result from an incorrect update. If the user tried to carry out this operation before the problem occurred, then he will have to contact for repair.
BIOS configuration errors are also common. It is very easy to solve this problem yourself by simply going to the SETUP menu and loading the default settings, for example, selecting the Load Setup Defaults option.
Errors in Windows operation can lead to the OS not starting. First of all, you need to find out their cause and try to solve it. In addition, you can try reinstalling the operating system or restoring the one installed from the factory.
Laptop won't turn on at all
Very often the laptop does not turn on at all due to power problems. But ? The power button lights up after pressing and nothing further happens. You will have to look for the cause and eliminate it.
- Typical actions that cause a laptop to stop turning on:
- dust cleaning;
- update;
After cleaning
and after overheating.
Cleaning a laptop involves disassembling it. The first thing you need to do is disassemble it again and check the connection of all components, as well as the installation of the cooling system. It would be useful to pay attention to the thermal paste and the serviceability of the tubes used for heat removal.
If the RAM modules were removed during the cleaning process, you should try to remove them again, clean the contacts and reinstall them. You also need to check whether the laptop starts with the hard drive and optical drive disconnected.
When re-disassembling, it is worth paying attention to the lid (display) opening sensor. If the assembly is not very careful, it may end up out of place.
In case execution simple tips did not lead to results and the device still does not work, then you should contact the service center. It is possible that during disassembly the elements were damaged by static electricity or another problem occurred.
After update
Problems may occur during the update. If updates are installed incorrectly, this may result in the computer not turning on.
In this case, the user can install a new BIOS version, drivers or patches for the operating system.
The most difficult case is the inability to start the computer after BIOS updates. This happens when the user tried to interfere with the process, for example, by rebooting or turning off the computer during it, or when using unofficial firmware.
Of course, resetting the settings to standard won't hurt. This can be done by removing the battery for a few minutes or by closing the corresponding jumper on the motherboard.
But as practice shows, this probably won’t help fix the problem. The only way out is to contact a service center for repairs.
In a situation where errors started after installing driver or Windows updates, you can simply roll back to the previous restore point from safe mode, reinstall the operating system, or return to the state it was in when you purchased it, if such a function is available in the model.
Hard drive is faulty
Usually, if a hard drive malfunctions, the startup occurs, but the system simply freezes at the manufacturer’s logo or displays information that the drive is not a system drive or is damaged. If the hard drive is detected in SETUP, then you can independently diagnose it by booting from and running a specialized utility, for example, Victoria.
If your worst fears are confirmed or the device cannot be detected in the BIOS, you need to check the cable.
After overheating
As a last resort, you need to replace the hard drive yourself or with the help of our specialists; to do this, click the “Request a call” button.
Modern computers generate quite a lot of heat during operation. If there is heavy dust or a malfunction of the cooling system, overheating may occur, after which some parts may fail. As a rule, it is impossible to solve the problem yourself; you will have to contact a service center for this.
- The main parts that can fail as a result of overheating are:
- CPU;
- video card;
- HDD;
Spontaneous shutdowns
north and south bridges.
In some cases, the computer may turn on and even work normally for a while. After which a spontaneous shutdown occurs. There are several main reasons for this.
- overheat;
- Let's look at typical problems that lead to the device turning off without instructions from the user:
- parts failure;
- viruses;
software errors.
Overheating is the most common cause of random shutdowns and reboots of mobile PCs, which can subsequently lead to device failure. In order to avoid this, it is necessary to regularly remove dust, and also sometimes change the heat-conducting paste.
Part malfunctions very often also occur due to overheating. If there have been no regular cleanings, then the likelihood of this is high. You won't be able to solve this problem on your own. Therefore, you should contact our specialist immediately. Viruses can lead to incorrect operation
system, as a result of which the PC may turn itself off. To solve this, you need to download special utilities from Doctor Web or Kaspersky Lab, perform a full scan and remove threats.
Software errors also often lead to random shutdown of the laptop. You need to find the reason using the code that appears on the screen at the time of the failure. After this, you should delete the problematic application or try updating to the latest version.
Checking for battery problems is quite simple. You need to take it out, connect the charger and start the laptop. If the glitches disappear, then you need to replace the battery.
It turns on, but... Windows startup, in others even initialization fails.
Fails to initialize
Initialization occurs at the moment the PC starts before the transition to booting Windows. If the indicators light up, the cooler turns on, but there is no access to the hard drive (the corresponding light does not light up), then the initialization most likely failed.
Possible reasons why the laptop may not initialize:
- malfunction of the processor, memory or video card;
- incorrect BIOS firmware;
- defects or damage to the south or north bridge.
Regardless of the reason, you will have to take the PC to a service center. Only specialist if available necessary equipment in this case, he will be able to accurately determine the cause of the problem and eliminate it.
Windows won't start
The inability to start Windows in most cases does not indicate hardware problems. Therefore, you can try to reinstall it, roll back to previous state PC or use recovery tools from the manufacturer.
In hardware, most often the inability to boot the OS is due to problems of hard disk. In this case, it will have to be replaced. You can first try to diagnose special utilities
, booting from removable media.
There are a lot of options for laptop malfunctions. You can diagnose and fix many of them yourself at home, but in the event of a serious breakdown you will still have to contact the specialists of our service center.
One of the most common problems with which people turn to a computer service is the problem associated with turning on the laptop. What should you do if you turn on your computer and see a black screen? In this article we will try to highlight all the reasons why the laptop stopped turning on. At first, it may seem that the problem is very serious, requiring the intervention of an experienced specialist. In fact, such problems are often associated with ordinary user inattention and can be solved quite simply.
- All problems can be divided into two groups:
- The computer turns off by itself.
The computer turns off during the game or displays a black screen.
— The computer turns off by itself. Your laptop may work properly, but at one point a black screen may appear or stop turning on, what should you do? Most often, the reason is that the battery has exhausted its resource. To solve this problem, simply replace it. If you don't have this option now, you can simply pull it out and reinsert it into your laptop. Perhaps the battery will charge and work again (though not for long). You can also simply remove your battery and connect it to power, in which case your laptop will run on electricity.
— Conflict with external media. It often happens that the laptop does not turn on due to the fact that a flash drive, camera, video camera is connected to it... Or the computer’s screen immediately goes blank when these devices are connected... In this case, you need to disconnect external media and try to turn on your device.
— A problem with motherboard . Motherboard is the most important component of any computer. The damage to her death is similar. This often happens due to careless handling of the laptop, impacts on it... In this case, doing something yourself is useless and the only solution to the problem is to replace it.
— Bad contacts. This problem occurs when you have a missing battery in your laptop. A common problem in this case is poor contacts. Check that all wires are securely attached to the computer. It is also worth checking that the outlet is working properly.
— Problem with components. Most often this is overheating of the processor or video card. The reasons may be different, but the most common is dusty laptop. To prevent this problem, you need to clean your laptop from dust at least once every six months. If you are not confident in your abilities, then it is better not to do anything yourself, but to entrust the matter to professionals.
— Malware can block your computer from working. The symptoms are simple: the computer restarts upon startup or displays a black screen instead of the desktop. computer This problem can be solved in three ways. The first is to go into safe mode and from there scan your computer with an antivirus. The best option here is Dr Web Cureit. The second way is to “roll back” the system to the moment when it was working properly. This method is guaranteed to save you from almost all problems associated with the inability to turn on the computer (except for hardware ones).
The third way is banal reinstalling Windows. The most common way to solve problems, which, however, has some disadvantages.
— Driver problem. After installing the driver, did your computer turn off or show a black screen? Most likely, the issue is with the driver. The best way The solution to the problem is to reinstall the driver or roll back the system. Steps: Start > Control Panel > All Control Panel Items > Recovery > Run System Restore.
— Has been damaged or deleted system file . May be the result of user actions or a virus. Reinstalling the system or rolling back helps.
— Registry problem. Over time, the registry becomes contaminated with unnecessary junk, as a result of which the laptop may slow down or intermittently crash. In this case, it is necessary to perform a system rollback. It is also necessary to regularly make copies of the registry.
— Bios problem. What to do? This problem can be solved by resetting the settings. This will cause the Bios to return to its original state and the computer will start normally again. After pressing the computer's power button, immediately press the Bios entry button (for different operating systems it's different). You wait a little. Next, press the F9 key (reset Bios settings) and press Enter (confirm the reset). If the problem was in Bios, then your computer is guaranteed to start; if not, then the problem is something else.
Computer turns off while playing
It happens that we launch a game and the laptop turns off, or instead of our favorite shooter we see a black screen in front of us. What to do and what are the reasons for the breakdown?
- The most common reason is excessive load on the power supply. Very often “heavy games” are to blame for this. If you are sure that the problem is not in the game, but in the power supply itself, then you need to replace it with a better one.
- Processor problem. When we launch some demanding game, the load on the processor increases many times over, and a black screen may appear. Accordingly, if the temperature sensors detect an excess of temperature on the computer, then the protection mode is triggered and your computer simply turns off. Most likely, your cooling system is outdated. The best option- This is a replacement cooler for the processor.
