What is a PC?
A personal computer is a precision instrument called a personal computer.A personal computer is a small computer (electronic computer) that has a price/size/performance for individuals and is used in many places, including the company, school, and home.The types of computers are desktop, notebook, tablet, etc.
What causes the computer to turn off or off?
When the computer is turned off, the following causes may be considered.
1. Failure of parts and parts inside the computer
2. Undercharged (for laptops)
3. Battery exhaustion, deterioration, or failure
4. Failure or disconnection of power plugs and cables
5. Due to lack of electricity
6. Memory failure or replacement compatibility
7. Heat Runaway and Other Heat Causes Forced Shutdown
8. Electrostatic and Charging
9. Overloading the CPU
10.Virus infection
11. Vibrations and shocks
1. Failure of parts and parts inside the computer
The parts and parts that make up the computer are consumables.If you use it for a long time or for a long time, it may break down due to aging.Failure of internal hard drives, solid state drives (SSDs), motherboards, CPUs, fan failures, external cables, etc. can often result in a computer failure.
·Hard drive (hard disk) or solid state drive (SSD)
Hard drives and SSDs store data, files, and operating systems in a personal computer.If the computer suddenly loses power, the system files in the operating system may not be able to start properly due to a failure of the hard drive or SSD.If the power is suddenly turned off, it may be the operating system, and if the operating system is malfunctioning, it may be necessary to estimate a hard drive or SSD failure.
2. Undercharged (for laptops)
When using a laptop, if the battery is low, it may be forced to shut down or power down.Simply, if the battery is undercharged, it can be used if the battery is fully charged.If you suddenly shut down while using your laptop, check if the battery level is low or sufficient.
3. Battery exhaustion, deterioration, or failure
In the case of a laptop, the internal battery may run out, deteriorate, or fail.①It′s been several years since I bought it. 充電 If there is a problem even after charging enough, it is estimated that the battery is causing the problem.The battery will definitely deteriorate depending on the usage period.Be careful when you feel that the battery life has decreased faster after using it for a few years.This is a sign that the battery is deteriorating.
4. Failure or disconnection of power plugs and cables
If you are supplying power directly through a cable without using a battery, check whether the plug or cable is plugged in or not.Problems may occur due to broken or disconnected cables and plugs, not the computer itself.Let′s check the wall outlet when you are taking the power.Plugs and cables are about to come off, and poor contact may cause problems.Let′s check when trouble occurs.
5. Due to lack of electricity
If the computer is turned off or off, it will start when the power is turned on again, but if the power is suddenly turned off suddenly, it can be inferred that the cause is a power shortage.①If you use more than one device at a time that consumes a lot of electricity, the power supply may become unstable or insufficient.Check the power consumption of the tap you are using (the standard number of taps is 1500W) and whether the tap for OA equipment is stable.If you print a printer that requires a lot of power, or if you have a heavy graphics load, such as online games, it consumes a lot of power.When using a build-to-order computer or a self-made computer, adding and expanding graphics boards (video cards), memory, optical drives, HDDs, etc. may cause the computer to suddenly lose power due to insufficient power capacity.
6. Memory failure or replacement compatibility
Memory is a part that temporarily records files on a computer, and larger memory capacity increases efficiency.Due to lack of memory, the operation will be adversely affected, leading to problems such as the inability to open files and apps.The computer may suddenly turn off due to memory corruption, incompatibility or incompatibility when adding, replacing, or installing new memory.If there is a memory cause, 頻繁 it freezes frequently フ it freezes frequently 作業 it freezes and shuts down frequently 中 it causes the keyboard and mouse to become unstable and unable to move while working.
7. Heat Runaway and Other Heat Causes Forced Shutdown
I bring heat when I use a computer.Precision equipment is vulnerable to heat and will be forced to shut down if it exceeds a certain temperature.In case of trouble caused by heat such as thermal runaway, 機器 Dust and dust are accumulated inside the equipment 熱 The fan that releases heat is broken · The cooling capacity of the fan is deteriorating CPU The deterioration of grease between the CPU and the cooling fan is estimated.Fans are prone to accumulating dust and dirt, and if you don′t clean it a little bit, it won′t work well and the heat dissipation will be delayed.As a result, heat builds up inside the equipment.Especially in summer, it can be affected by indoor temperature and installation location temperature.Notebooks are sensitive to heat, so consider your environment.
8. Electrostatic and Charging
Static electricity is a big enemy of precision equipment.In the case of personal computers, especially the motherboard and internal parts can be damaged by static electricity, and can cause malfunctions such as sudden power loss.Electrostatic and electrification are easy to occur in dry seasons such as winter.In the event of a malfunction, it can be improved by unplugging cables and extension cords for a few minutes or leaving them overnight.
9. Overloading the CPU
A CPU (central processing unit or central processing unit) is a central processing unit (processor) in a computer, also known as the computer′s brain.It is responsible for control and computation within a computer and is one of the most demanding parts in a PC.There are cases where the CPU is under heavy load and suddenly the power is turned off.
10.Virus infection
Even if you get infected with a virus, your computer will become unstable or unexpected.Virus infections can be transmitted at unexpected times, such as when malicious sites are opened, when emails are opened, when software is downloaded, or when external media such as USB memory is infected with viruses and is connected to a PC.In order to prevent viruses from entering, you should consider regularly upgrading your OS and software and using security software.
11. Vibrations and shocks
When the computer is moved or dropped, vibrations may cause the computer to suddenly turn off and shut down.It can lead to problems such as loose installation of parts due to vibration and sudden power down when parts are broken by impact.The vibration and impact of precision instruments such as personal computers are a big enemy.In the unlikely event that vibrations or shocks are added or broken, doing nothing is the best solution.

What Causes a PC to Break and How to Deal with a Failure?
https://www.adte.jp/rec/hdd/post-1687/
This computer is used in many places such as work, private life, hobbies and schools.You may have thought ′Is your computer broken?′ when you suddenly turned off while using it, your computer couldn′t start, your computer didn′t work with a blue screen or a black screen, and you got an error message.Here are some examples of symptoms and possible causes that occur when a computer fails, such as whether important data is included or whether it should be repaired.
as a way of determining the cause of a sudden power outage
If you experience symptoms such as power off, sudden shutdown, freeze, harden, reboot, do not boot, or do not wake up, you may be able to help identify symptoms and find solutions by checking the Windows event log.
·How to check the Windows event log
①Right-click the start button in the lower left corner of the screen → Select Computer Management
②Computer Management → System Tools → Event Viewer → Windows Logs → System Deployment
③Check the System Event Log for Critical Levels
ログ While checking the log, you need to be careful with the log that shows event 41.The cause of the system shutdown is unknown, and it is difficult to determine the cause, so it is not recommended to continue working.Priority should be given to contacting a professional repair and restoration company.
CPU BIOS will reboot if there is a problem as a result of high CPU temperature.In that case, the log is not saved in the event log, and it may lead to a blue screen screen (blue screen).The BIOS log check method differs depending on the manufacturer of the computer, depending on the BIOS menu and BIOS boot key.
↓ Here′s how to deal with a blue screen (blue screen) on your computer
AT DATA RECOVERY MEDIUM
What do I do when my computer turns blue?
https://www.adte.jp/rec/hdd/post-1267/
Have you ever had trouble with the blue screen when you were using the computer or when you started?I feel uneasy when only the message is displayed on the switched blue screen.The white message on the blue screen is an error code.It′s important to think about the cause and how to deal with problems that have occurred on your computer.In this section, we will show you how to deal with the problem so that you can solve it as soon as possible when the computer is blue-screened.
What to do when the power is off or turned off?
If you experience symptoms such as the computer being turned off, let′s check and take action in the following order.There are many reasons why symptoms appear on the computer, and it is often difficult to identify them.If you continue to work, if you touch it badly, the condition may deteriorate, and the damage may spread.If the PC itself is important, if the data stored is important, or if it is difficult to run out, it would be safer to stop and consult a specialist restoration and repair company before proceeding.
1. Disconnect all connected devices and discharge them before performing any work or action.
2. When battery consumption, deterioration, or power shortage is considered
3. When the computer is hot, such as a runaway heat,
4. Utilizing Hardware Diagnostics
5. When the hard disk is out of order
6. When a memory defect is estimated
7. If you suspect a problem with the installed software,
8. Reinstall the operating system if you suspect a problem with the operating system.
1. Disconnect all connected devices and discharge them before performing any work or action.
When working on a PC that is experiencing problems, first remove all connected devices.The procedure is as follows.
·Discharge method
①Verify the Power Is Off
②Desktop: Unplug the power cord or AC adapter
NOTEBOOK TYPE: REMOVE BATTERY
③Disconnect all connected devices and peripherals such as keyboards, mice, USB memory, and external hard drives
④Leave it for a while after removing it *Discharge operation
⑤In addition, I will remove all items that have changed from the original condition of purchase, such as adding additional parts.
⑥Leave for about 10 minutes
⑦Unnecessary power discharged.eliminate the electrification conditions
If the reason for the power loss is charged, this may be the solution.Measures that can be prevented on a daily basis include not storing static electricity, using static electricity removal goods, and improving the dry indoor environment in winter.
2. When battery consumption, deterioration, or power shortage is considered
①If you are using a laptop computer rather than a desktop computer, the battery may not charge enough, deteriorate, or overdischarge, causing the power to become unstable and suddenly shut down, and the power may be turned off.Connect the AC adapter directly to the outlet instead of the battery to see if it is receiving power.It is estimated that the battery is broken when the operation is stable without using the battery.When the battery is fully charged but the operation is not stable, it is estimated that it is worn out due to aging and life expectancy.It is said that the battery life of a laptop computer is usually 2-3 years.
②when supplying power from an extension cord
The extension cord may be broken.Let′s stop using the extension cord and take the power directly from the outlet.When the computer is able to start normally by connecting it to an electrical outlet, we can guess that the extension cord is broken.
③The power cord is disconnected.
If the symptom does not improve even if you take power directly from the outlet, it is estimated that the power cable is broken or disconnected.Cables are especially prone to disconnection at the root.Depending on how you touch it and the angle, you may be able to move temporarily.However, it is dangerous to continue using disconnected cables.It may lead to the progress of the failure and the ignition.Cables are one of the consumables.Let′s exchange it when you feel uneasy.
3. When the computer is hot, such as a runaway heat,
Parts in precision equipment heat up when they are in use, and if the heat exceeds the allowable amount, it causes problems such as turning off the computer.Parts such as foundations and circuits may melt and break down by heat.This is thermal runaway.The CPU is designed to be forced to shut down when the temperature is above a certain level.
①When I feel unusually hot after touching the computer,
Let′s stop using it and wait for the heat to go away.
②when dust is accumulating
If you visually judge that dust is accumulating, you should actively clean it.When dust is accumulated in the vent, it is difficult to discharge heat from the equipment, which can also lead to the inability to discharge.If you are using a laptop that can easily open the case and remove the back lid, you should open the case and clean the dust inside.In particular, cooling fans are prone to dust accumulation, which is a factor that reduces cooling.Clean with the CPU fans.It is also important to unplug the power cord and turn it off when working.Don′t push yourself too hard when you find it difficult or environmentally difficult to break down your computer.Let′s only clean the outside of the computer.
③in the event of a site or environmental problem
It is also important to create an environment where heat is easily discharged from the computer itself.Fans breathe in the outside air and push out the heated air with fans, so when there are many things around the fans, or when the surroundings of the fans are blocked, the heat builds up and leads to a thermal runaway.It is important to keep the device from getting hot, such as the desktop type is often located on the back of the case, and the notebook type is often equipped with a fan underneath, not on a cloth such as a lap blanket, or in places where direct sunlight does not stick to the desk.
④adjustment of room temperature
Electronics and precision equipment are vulnerable to temperature changes.Try not to use your computer too hot or too cold.If you use it in a room that is too hot or too cold, the computer may not work properly or the power may suddenly turn off.It′s the right temperature for precision equipment to feel cool.

PC thermal runaway is a dangerous sign! Introduce the cause of the heat and how to deal with it
https://www.adte.jp/rec/hdd/post-998/
Have you ever felt that the operation was unstable, such as repeated unintended reboots, freezing screens, or turning off the power on your own while using your computer?When you touch the computer, you need to be careful and take countermeasures when the main body feels unusually hot.If your computer is running wild, the risk of failure will increase if you continue to use it.Here are some things to be careful about and how to deal with when a personal computer thermal runaway occurs.
4. Utilizing Hardware Diagnostics
If you are familiar with using a computer, try the hardware diagnostics.Hardware diagnostics can help you determine where the problem is with the hardware.
·Hardware diagnostic method
①Start the BIOS where the PC manufacturer′s logo appears.
②Run Diagnostics When the System Setup Is Up → Hardware Diagnostics Starts
パソコン The computer contains a program called BIOS that controls and manages internal parts such as motherboard, infrastructure, storage mouse, keyboard drive, etc.Press the power button → Boot to PC → Boot to BIOS → Recognize each part (memory, CPU, storage, drive, graphics board, internal hard disk, etc.) → Boot to OS (Windows, iOS, etc.) → Operational flow.Booting into the BIOS and performing hardware diagnostics can help determine if there is a memory problem, a hard disk problem, or a CD, DVD, or BD drive problem.Hard disks and memory are the most common components that cause problems or failures.
5. When the hard disk is out of order
Hard disks are the most prone to failure among the components of personal computers.The built-in hard disk stores not only the data you created and downloaded, but also the OS information. If the hard disk is broken, the OS will not be called → Power will be turned off, the PC will not work, will not stand up, and will not boot.If the hard disk fails, the data may disappear or disappear due to continuous operation such as turning off the power or rebooting repeatedly, so you need to be careful when handling it.If you suspect a hard disk failure, contact a specialist repair and repair company immediately.

What do I do when I want to retrieve data from a failed hard drive?
https://www.adte.jp/rec/hdd/post-1307/
Hard drives are the most prone to failure among server components such as personal computers and NAS.A hard drive is one of the recording media that stores important data, and if it is broken, data can be lost, so be careful when handling it.Here′s how to retrieve and troubleshoot data in the event of a hard drive failure.
6. When a memory defect is estimated
When the memory is broken, the computer won′t start up, the power goes down, shuts down repeatedly, shuts down frequently, and the keyboard and mouse are malfunctioning.
①in the event of a thermal runaway
When a personal computer is experiencing a thermal runaway, it is possible that the memory is also at a high temperature.There are many models that do not have fans because memory is less hot than other parts.Like the fan, dust accumulates in the memory area, causing problems such as symptoms and not working properly.It is also important to create an environment where memory can be cooled.
②Memory itself failed
When the computer starts up, the file is temporarily stored in memory, but if the memory is broken, there will be no place to put the file, which will lead to a situation where it cannot be started.If the memory chip is damaged, the motherboard will not be able to recognize the memory, which will lead to a bug where information cannot be read.It is estimated that the chip is malfunctioning when there is a problem with the computer that was normally used without any problems.This is a common case even in the case of initial failure.
·How to check memory conditions and faults
①Open Windows Management Tools
②Deploy Windows Memory Diagnostics
③Check memory status
④Memory failure identified requires replacement
互換Finding and replacing compatible memory requires technical skills, expertise, clean rooms, and other environmental and equipment, so if you think the memory itself is faulty, leave it to a professional recovery and repair company.
7. If you suspect a problem with the installed software,
If you experience symptoms such as frequently turning off the power after installing the software or shutting down after starting a specific software, the software may be the cause.Let′s look carefully at what software you used before the power went off.When you′re running games or 3D graphics-intensive software, it puts a lot of pressure on the CPU.When the load is applied, it becomes high temperature and leads to thermal runaway.If you know the software that may be the cause, you can uninstall it for improvement.In addition, there are the following ways to return the symptom to the previous state.
·OS is Windows: Use System Restore
·OS is iOS (Mac): Use Time Machine function
Please be aware that this function can be used when you are backing up on a daily basis.
8. Reinstall the operating system if you suspect a problem with the operating system.
If the computer suddenly turns off, it may be a problem with the operating system.In addition, if the power goes down during the operating system update, the system will be damaged.You may not be able to start your computer.If there is a cause of the operating system, you can expect to resolve the problem by reinstalling the operating system.However, reinstalling the operating system is a last resort.There are concerns that reinstalling the operating system may cause the data stored inside to disappear.In case of trouble, consult a specialist restoration and repair company before proceeding with the work.
When you want to retrieve data from a powered-down PC,
When you want to retrieve data from a recording medium or a personal computer that has a problem such as a sudden power failure, you need to determine the cause of the failure.If you can′t improve the situation by trying out the solutions mentioned above, or if the data you have stored is important, important, or the device itself is important, the damage may spread and the condition may worsen.Defects are occurring = This sign is often broken, so it can be said that it needs to be dealt with as soon as possible.If you think about it even a little bit, it′s better to leave it to a professional restoration company or repair company.

What do I do when my computer turns blue?
https://www.adte.jp/rec/hdd/post-1267/
Have you ever had trouble with the blue screen when you were using the computer or when you started?I feel uneasy when only the message is displayed on the switched blue screen.The white message on the blue screen is an error code.It′s important to think about the cause and how to deal with problems that have occurred on your computer.In this section, we will show you how to deal with the problem so that you can solve it as soon as possible when the computer is blue-screened.
What to do when the power is off or turned off?
If you experience symptoms such as the computer being turned off, let′s check and take action in the following order.There are many reasons why symptoms appear on the computer, and it is often difficult to identify them.If you continue to work, if you touch it badly, the condition may deteriorate, and the damage may spread.If the PC itself is important, if the data stored is important, or if it is difficult to run out, it would be safer to stop and consult a specialist restoration and repair company before proceeding.
1. Disconnect all connected devices and discharge them before performing any work or action.
2. When battery consumption, deterioration, or power shortage is considered
3. When the computer is hot, such as a runaway heat,
4. Utilizing Hardware Diagnostics
5. When the hard disk is out of order
6. When a memory defect is estimated
7. If you suspect a problem with the installed software,
8. Reinstall the operating system if you suspect a problem with the operating system.
1. Disconnect all connected devices and discharge them before performing any work or action.
When working on a PC that is experiencing problems, first remove all connected devices.The procedure is as follows.
·Discharge method
①Verify the Power Is Off
②Desktop: Unplug the power cord or AC adapter
NOTEBOOK TYPE: REMOVE BATTERY
③Disconnect all connected devices and peripherals such as keyboards, mice, USB memory, and external hard drives
④Leave it for a while after removing it *Discharge operation
⑤In addition, I will remove all items that have changed from the original condition of purchase, such as adding additional parts.
⑥Leave for about 10 minutes
⑦Unnecessary power discharged.eliminate the electrification conditions
If the reason for the power loss is charged, this may be the solution.Measures that can be prevented on a daily basis include not storing static electricity, using static electricity removal goods, and improving the dry indoor environment in winter.
2. When battery consumption, deterioration, or power shortage is considered
①If you are using a laptop computer rather than a desktop computer, the battery may not charge enough, deteriorate, or overdischarge, causing the power to become unstable and suddenly shut down, and the power may be turned off.Connect the AC adapter directly to the outlet instead of the battery to see if it is receiving power.It is estimated that the battery is broken when the operation is stable without using the battery.When the battery is fully charged but the operation is not stable, it is estimated that it is worn out due to aging and life expectancy.It is said that the battery life of a laptop computer is usually 2-3 years.
②when supplying power from an extension cord
The extension cord may be broken.Let′s stop using the extension cord and take the power directly from the outlet.When the computer is able to start normally by connecting it to an electrical outlet, we can guess that the extension cord is broken.
③The power cord is disconnected.
If the symptom does not improve even if you take power directly from the outlet, it is estimated that the power cable is broken or disconnected.Cables are especially prone to disconnection at the root.Depending on how you touch it and the angle, you may be able to move temporarily.However, it is dangerous to continue using disconnected cables.It may lead to the progress of the failure and the ignition.Cables are one of the consumables.Let′s exchange it when you feel uneasy.
3. When the computer is hot, such as a runaway heat,
Parts in precision equipment heat up when they are in use, and if the heat exceeds the allowable amount, it causes problems such as turning off the computer.Parts such as foundations and circuits may melt and break down by heat.This is thermal runaway.The CPU is designed to be forced to shut down when the temperature is above a certain level.
①When I feel unusually hot after touching the computer,
Let′s stop using it and wait for the heat to go away.
②when dust is accumulating
If you visually judge that dust is accumulating, you should actively clean it.When dust is accumulated in the vent, it is difficult to discharge heat from the equipment, which can also lead to the inability to discharge.If you are using a laptop that can easily open the case and remove the back lid, you should open the case and clean the dust inside.In particular, cooling fans are prone to dust accumulation, which is a factor that reduces cooling.Clean with the CPU fans.It is also important to unplug the power cord and turn it off when working.Don′t push yourself too hard when you find it difficult or environmentally difficult to break down your computer.Let′s only clean the outside of the computer.
③in the event of a site or environmental problem
It is also important to create an environment where heat is easily discharged from the computer itself.Fans breathe in the outside air and push out the heated air with fans, so when there are many things around the fans, or when the surroundings of the fans are blocked, the heat builds up and leads to a thermal runaway.It is important to keep the device from getting hot, such as the desktop type is often located on the back of the case, and the notebook type is often equipped with a fan underneath, not on a cloth such as a lap blanket, or in places where direct sunlight does not stick to the desk.
④adjustment of room temperature
Electronics and precision equipment are vulnerable to temperature changes.Try not to use your computer too hot or too cold.If you use it in a room that is too hot or too cold, the computer may not work properly or the power may suddenly turn off.It′s the right temperature for precision equipment to feel cool.

PC thermal runaway is a dangerous sign! Introduce the cause of the heat and how to deal with it
https://www.adte.jp/rec/hdd/post-998/
Have you ever felt that the operation was unstable, such as repeated unintended reboots, freezing screens, or turning off the power on your own while using your computer?When you touch the computer, you need to be careful and take countermeasures when the main body feels unusually hot.If your computer is running wild, the risk of failure will increase if you continue to use it.Here are some things to be careful about and how to deal with when a personal computer thermal runaway occurs.
4. Utilizing Hardware Diagnostics
If you are familiar with using a computer, try the hardware diagnostics.Hardware diagnostics can help you determine where the problem is with the hardware.
·Hardware diagnostic method
①Start the BIOS where the PC manufacturer′s logo appears.
②Run Diagnostics When the System Setup Is Up → Hardware Diagnostics Starts
パソコン The computer contains a program called BIOS that controls and manages internal parts such as motherboard, infrastructure, storage mouse, keyboard drive, etc.Press the power button → Boot to PC → Boot to BIOS → Recognize each part (memory, CPU, storage, drive, graphics board, internal hard disk, etc.) → Boot to OS (Windows, iOS, etc.) → Operational flow.Booting into the BIOS and performing hardware diagnostics can help determine if there is a memory problem, a hard disk problem, or a CD, DVD, or BD drive problem.Hard disks and memory are the most common components that cause problems or failures.
5. When the hard disk is out of order
Hard disks are the most prone to failure among the components of personal computers.The built-in hard disk stores not only the data you created and downloaded, but also the OS information. If the hard disk is broken, the OS will not be called → Power will be turned off, the PC will not work, will not stand up, and will not boot.If the hard disk fails, the data may disappear or disappear due to continuous operation such as turning off the power or rebooting repeatedly, so you need to be careful when handling it.If you suspect a hard disk failure, contact a specialist repair and repair company immediately.

What do I do when I want to retrieve data from a failed hard drive?
https://www.adte.jp/rec/hdd/post-1307/
Hard drives are the most prone to failure among server components such as personal computers and NAS.A hard drive is one of the recording media that stores important data, and if it is broken, data can be lost, so be careful when handling it.Here′s how to retrieve and troubleshoot data in the event of a hard drive failure.
6. When a memory defect is estimated
When the memory is broken, the computer won′t start up, the power goes down, shuts down repeatedly, shuts down frequently, and the keyboard and mouse are malfunctioning.
①in the event of a thermal runaway
When a personal computer is experiencing a thermal runaway, it is possible that the memory is also at a high temperature.There are many models that do not have fans because memory is less hot than other parts.Like the fan, dust accumulates in the memory area, causing problems such as symptoms and not working properly.It is also important to create an environment where memory can be cooled.
②Memory itself failed
When the computer starts up, the file is temporarily stored in memory, but if the memory is broken, there will be no place to put the file, which will lead to a situation where it cannot be started.If the memory chip is damaged, the motherboard will not be able to recognize the memory, which will lead to a bug where information cannot be read.It is estimated that the chip is malfunctioning when there is a problem with the computer that was normally used without any problems.This is a common case even in the case of initial failure.
·How to check memory conditions and faults
①Open Windows Management Tools
②Deploy Windows Memory Diagnostics
③Check memory status
④Memory failure identified requires replacement
互換Finding and replacing compatible memory requires technical skills, expertise, clean rooms, and other environmental and equipment, so if you think the memory itself is faulty, leave it to a professional recovery and repair company.
7. If you suspect a problem with the installed software,
If you experience symptoms such as frequently turning off the power after installing the software or shutting down after starting a specific software, the software may be the cause.Let′s look carefully at what software you used before the power went off.When you′re running games or 3D graphics-intensive software, it puts a lot of pressure on the CPU.When the load is applied, it becomes high temperature and leads to thermal runaway.If you know the software that may be the cause, you can uninstall it for improvement.In addition, there are the following ways to return the symptom to the previous state.
·OS is Windows: Use System Restore
·OS is iOS (Mac): Use Time Machine function
Please be aware that this function can be used when you are backing up on a daily basis.
8. Reinstall the operating system if you suspect a problem with the operating system.
If the computer suddenly turns off, it may be a problem with the operating system.In addition, if the power goes down during the operating system update, the system will be damaged.You may not be able to start your computer.If there is a cause of the operating system, you can expect to resolve the problem by reinstalling the operating system.However, reinstalling the operating system is a last resort.There are concerns that reinstalling the operating system may cause the data stored inside to disappear.In case of trouble, consult a specialist restoration and repair company before proceeding with the work.
When you want to retrieve data from a powered-down PC,
When you want to retrieve data from a recording medium or a personal computer that has a problem such as a sudden power failure, you need to determine the cause of the failure.If you can′t improve the situation by trying out the solutions mentioned above, or if the data you have stored is important, important, or the device itself is important, the damage may spread and the condition may worsen.Defects are occurring = This sign is often broken, so it can be said that it needs to be dealt with as soon as possible.If you think about it even a little bit, it′s better to leave it to a professional restoration company or repair company.
