The automatic shutdown problem of computer hosts troubles many users, causing inconvenience to their work and entertainment. This problem could have several causes, including hardware failure, software issues, or an unstable power supply. In this article, PHP editor Xiaoxin will provide you with a detailed analysis of common causes and solutions for computer hosts to automatically shut down, helping you quickly solve the problem and restore the normal operation of the host.
Why does the computer host automatically shut down?
The computer is one of the indispensable tools for modern people's work and study, but During use, sometimes the computer host automatically shuts down, which makes people feel confused and anxious. In daily life, computers may automatically shut down due to a variety of factors. Next, let’s discuss the reasons why the computer host automatically shuts down and how to solve them.
Faced with the problem of computer host automatically shutting down, we can solve it from the following aspects:
1. Heat dissipation optimization: Regularly clean the dust inside the computer to ensure a good heat dissipation environment, which can effectively reduce automatic heat dissipation caused by overheating. shutdown situation. 2. Power supply check: Check whether the power supply connection is firm. If there is any looseness, fix it in time to ensure stable and reliable power supply. 3. Hardware detection: Conduct a comprehensive inspection of computer hardware to find possible faulty hardware and replace or repair it in a timely manner. 4. System repair: Repair or reinstall the operating system to solve automatic shutdown problems caused by system failures. 5. Anti-virus protection: Use reliable anti-virus software to perform a full scan to remove viruses and malware from your computer to ensure system security and stability.In general, the automatic shutdown of the computer host may be caused by a variety of reasons, and it is necessary to comprehensively analyze and take corresponding solutions based on the specific situation. Through routine maintenance and paying attention to the computer usage environment, you can effectively prevent the automatic shutdown of the computer host and ensure the stable and reliable operation of the computer.
The reason why the computer always shuts down automatically and the solution are as follows:
The first reason: There is a problem with the computer’s CPU fan or the radiator (for example, the radiator material is very poor, which also means the radiator’s heat conduction Performance is not very good): If there is too much dust on your CPU fan and the fan is stuck, causing the CPU to not cool down. When the temperature reaches the temperature set by the motherboard, the motherboard starts protection and automatically shuts down. The quality of the radiator is poor, or the radiator clip is not tight enough, which can also cause automatic shutdown, for the same reasons as above.
Solution: Clean the dust on the CPU fan. If the CPU fan is broken, replace it with a better fan and a good radiator. If the clip is loose, reinstall the clip. Also add some silicone grease to the CPU to help cool down the CPU.
Fans and radiators
The second reason is: the power of your power supply is small, and it works normally at first. When you play larger games, the voltage used by the graphics card increases, causing the voltage of the power supply to also increase. High, the power configured by your power supply is too low, and the power supply activates overvoltage protection, so it automatically shuts down.
Method: Jianyi replace the power supply with one with a larger rated function.
Host power supply
The third reason: the voltage in your place is unstable. When the voltage is not between 170V---240V, it will automatically shut down and restart from time to time. Jianyi uses a UPS uninterruptible power supply. , which plays the role of voltage stabilization and protection.
The fourth reason: the virus destroys certain files in the system. When it runs to a certain level, as the CPU usage and memory usage continue to increase, after reaching 100%, the computer will freeze and automatically shut down. , Jianyi uses anti-virus software to perform full anti-virus in safe mode. If anti-virus fails, then reinstall the system or restore it with one click.
The fifth reason: Your computer uses some software that can set a scheduled shutdown. If you set a scheduled shutdown, it will shut down at that time. For example, if you use: Thunder, Express, Anti-virus software, BT download, video playback, etc. In the software settings, there is an action to automatically shut down after completing a certain task. But generally the default setting is off. Its purpose is to automatically shut down the computer after completing the task when running a time-consuming operation.
Thanks for the invitation
In your case, if the computer can still be turned on after it is turned off, it means there is a heat dissipation problem. But as you said, if it automatically shuts down at %20 and then cannot be started, then it is caused by a weak battery. The only way is to replace the battery. I don’t know if you plugged it in for charging when using it. If not, it’s a power issue. You haven't made it clear yet. If you don't understand, you can contact me.

With the continuous development of technology, computers have become our life One of the indispensable tools. However, sometimes we encounter some annoying problems, such as the computer host automatically shutting down. This problem not only affects our work efficiency, but also affects our mood. So, how should we solve this problem? This article will introduce you to some methods to solve the problem of computer host automatically shutting down.
First of all, to solve the problem of the computer host automatically shutting down, we need to check whether the hardware is normal. It may be due to insufficient power supply, poor heat dissipation, memory damage, etc. that the computer host automatically shuts down. In this case, we can first check whether the power cord is loose and whether there are power fluctuations and other problems. If the power supply is insufficient, we can replace it with a high-quality power adapter to ensure that the computer receives a stable power supply.
In addition, heat dissipation problems are also one of the common reasons why the computer host automatically shuts down. If the CPU temperature is too high, the computer will automatically shut down to protect the hardware from damage. Therefore, we can clean the cooling fan, replace the cooling grease, etc. to solve the cooling problem.
In addition, if the memory is damaged, it may also cause the computer host to automatically shut down. We can solve this problem by replacing the memory module or testing the memory.
In addition to hardware problems, software problems may also cause the computer host to shut down automatically. Problems such as system crashes and virus infections may cause the computer host to shut down automatically. In this case, we need to check for viruses, update system patches, reinstall the operating system, etc. to solve the problem.
In addition, some incompatible software may also cause the computer host to shut down automatically. When installing software, we should pay attention to the compatibility of the software and avoid installing unsafe or incompatible software.
In addition to solving the problem, we can also take some measures to proactively prevent the computer host from automatically shutting down. For example, measures such as regularly cleaning the dust inside the computer, maintaining good heat dissipation, and not frequently cutting off power can help us reduce the possibility of the computer shutting down automatically.
Automatic shutdown of the computer host is a difficult problem, but as long as we patiently find the cause and take effective measures, we can solve this problem. I hope that the methods provided in this article can help everyone solve the problem of automatic shutdown of the computer host and keep our computers running stably.
Problem analysis:
Generally, automatic shutdown may be caused by high temperature caused by too much dust on the CPU fan.
If this is the problem, clean the dust on the CPU fan and heat sink, and add new thermal grease. If the cooling fan is broken, replace it.
If this is not the problem, it may be caused by problems with motherboard components or power supply, unstable voltage, hard drive failure, hardware overclocking, etc. There is also the incompatibility of new hardware. If you cannot find out the cause, it is recommended to repair it.
Common problems and solutions:
1. Voltage instability
Generally, the working voltage range of the switching power supply of home computers is 170V-240V. When the mains voltage is lower than 170V, the computer will automatically restart or shut down. Because we sometimes cannot feel the fluctuations in the mains voltage, we mistakenly think that the computer has automatically restarted inexplicably.
Solution: For areas with frequent unstable power supply, we can purchase UPS power supply or 130-260V wide switching power supply to ensure stable operation of the computer.
2. Poor contact
①Poor contact at the socket
Solution: Buy some famous brand power strips, because the inside of them are automatically installed and crimped by machines, and no manual welding is used. As for whether it is a virtual connection problem inside the wall socket, we can try changing the host to a wall socket to see if the same automatic restart problem exists.
②Poor contact of the power cord
Solution: Replace with a high-quality 3C certified power cord.
③Poor contact on the motherboard, hard drive, etc.
Solution: If the motherboard solder joints are weak, just use a soldering iron to repair them. If the problem is with the power supply, it is best to replace it with a good one.
3. Performance issues
This situation is relatively common, especially when we add new equipment to our host, such as replacing a high-end graphics card, adding a recorder, or adding a hard disk, it is easy to occur.
Solution: Replace with a high-quality, high-power computer power supply now.
4. CPU problem
Some functional circuits inside the CPU are damaged, and when the second-level cache is damaged, the computer can still start, and even enter the normal desktop for normal operations, but it will restart or freeze when a special function is performed. , such as drawing tables, playing VCD, playing games, etc.
Solution: Try to block the L2 cache or L1 cache in CMOS to see if the host can run normally; otherwise, just use a good CPU to replace it. If it can run normally after being shielded, you can still make do with it. Although it is slower, you will save money after all.
1. It is a common phenomenon for laptops to automatically shut down when the computer gets hot. This is a way of self-protection for the computer. This means that the laptop has been used continuously for more than a year and a half.
2. The reason for automatic shutdown is that the CPU is overheated. In order to protect the CPU from being burned, the computer shut down.
3. After the automatic shutdown, the user is warned that it is time to clean up the dust on the notebook. Dust cleaning must be done every one and a half years or so, otherwise this situation will happen again. If the operator has experience in dismantling the machine, he can dismantle the machine and clean the dust by himself. The radiator and fan are the most dusty.
