Why does the computer restart after shutting down?

The reason why the computer automatically restarts is:

1.Unknowingly, the Trojan trap designed by the hacker was run, and once it entered the netizens, it would become the puppet of the hacker and be manipulated at will.

2.Driver incompatibility problem, due to the incompatibility of the program, the computer will also automatically restart.

3.Hardware problems, memory, power supply, hard disk and other hardware problems will cause the computer to automatically restart.

The solution to the automatic restart of the computer frequently:

1.First of all, check whether the memory, power supply, and hard disk are plugged in firmly;

2.Then check whether the computer is poisoned, it is recommended that you install Kingsoft Guard to carry out a comprehensive investigation and killing of the computer, because Kingsoft Guard has the advantage of traditional antivirus software, and can automatically damage the system problems due to viruses and Trojans.

How to use: 1. Enter the main interface and enter [Kill Trojan].

2. Then click [Quick Scan].

3. Check whether the temperature of the hardware is too high, because the motherboard has a protection device, when a device in the hard disk reaches the temperature warning value, it will restart, and the temperature detection needs a hardware detection tool to see, which is not visible to the naked eye.

Then switch to the "Hardware Detection" function, which will automatically help you detect the hardware device details of your current computer and what the current temperature of the current hardware is, when your hardware temperature reaches a dangerous value, the temperature number color will become more and more red.

You can also set the temperature display to the desktop, and you can detect the hardware temperature in real time at any time.

4. Uninstall programs compatible with the computer department, it is recommended not to use the beta version of the program, because there are many bugs in this kind of program, it is recommended to uninstall and install the genuine program.

It may be a motherboard contact problem. You can check it.

In terms of software, try to start running shutdowm s t 0 or press and hold the host power button.

The hardware may be a motherboard issue.

Many friends may encounter such a situation, the computer is running well and automatically shut down or automatically restart, we often receive similar requests for help from netizens. Obviously, whether it is the automatic shutdown of the computer or the automatic restart of the computer is abnormal, so why does the computer automatically shut down and restart automatically?

Analyze the reasons why the computer will automatically shut down or restart. We also use the software-first approach to exclude hardware.

1. Viruses in the computer.

Generally speaking, many computer viruses will find this situation, when computer applications and core components are damaged by computer viruses, the computer may automatically shut down, and when there is malicious programs installed in the computer virus, it may be restarted to complete the installation of malware. The principle is similar to when we install some software. It is also common to find that some important security software needs to be restarted after installation.

2. The computer contains running software, and the task of automatic shutdown at the end of the operation is completed.

This situation is very common, and it is also a low-level mistake that novice friends are often prone to make, some of our more common software, after the software runs can be set to automatic shutdown, etc., such as more common, such as Thunderbolt, Express, antivirus software (360 antivirus and Kingsoft antivirus, etc.), bt**, **** and so on. In the software settings, there is an action that automatically shuts 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 more time-consuming operation, so if you find that the computer automatically shuts down, you need to check if there is any software that has such a setting.

Hardware: Three: Computer hardware heat dissipation problems lead to automatic shutdown.

Poor heat dissipation, power failure, and motherboard failure may cause the computer to shut down automatically or restart repeatedly. (Reboot is an important feature: sometimes it shuts down, sometimes it restarts), and it is more common for the computer processor (CPU) to have poor heat dissipation and excessive temperature, causing the computer to restart repeatedly.

Four: the computer host computer power switch is not in good contact.

I have encountered a computer like this, the computer is always automatically turned on after the regular shutdown, sometimes a boot is not into the page on the shutdown, the problem is very strange, and finally after a large number of elimination found that the computer host computer boot button internal failure.

Five: computer power supply problems.

The computer power supply is the power source of the computer, known as the heart or power station of the computer, if there is a problem with the computer, such as the unstable output of the computer, it is easy to cause the computer to restart or shut down.

Finally, let's talk about the solution of the automatic shutdown or restart of the computer, since the reason is found, the solution is relatively simple, if the automatic shutdown of the computer is caused by a virus, we first need to do a full scan of the computer, if the core components are damaged, need to be repaired, or system restoration to solve.

If it is due to some software that has set it to shut down automatically after the run, you only need to set it again to solve the problem. In terms of computer hardware, if the problem is caused by poor heat dissipation, you can try to clean the dust, add a cooling fan, etc., and if it is a computer hardware failure, you need to take it for repair.

The laptop uses AC power normally, and it turns off after a short time to remove AC power. It is preliminarily judged that the battery of the notebook has been seriously depleted.

You can rematch your laptop's battery. In addition, when using the laptop under the normal condition of alternating current, pay attention to whether the cooling system of the laptop is normal. If the heat dissipation temperature is high, deal with the laptop's heat dissipation system first.

Check to see if the software and notebook requirements are the same, and whether there is overwork.

It may be that the high temperature protection is up, and you can touch the back of the notebook with your hand to see if it is hot.

It may be that the battery is not working, and the power consumption is a little larger.

Is it a problem with the battery.

PC restarts automatically? Please take a look at the content below, I hope it will help you.

1. If it is an automatic shutdown when it does not enter the system, it goes without saying that it must be a hardware problem. If the CPU is overheated, there may be problems with the memory, graphics card, power supply, and hard disk

Clean up all kinds of fans, and use an eraser to erase the gold finger of memory, graphics card, and hard disk.

Press it again to check the data cable and power cable. The fan can be blown clean with a hair dryer, and the dust paper on the center shaft of the fan is removed and a few drops of cooking oil are dropped.

It can also reduce noise and increase speed.

2. If the computer is shut down after entering the system, it is recommended to click F8 at startup, and click to enter the system with the last correct configuration, and try to solve it!

3. Open the hardware detection software, such as the host hardware and operating system benchmarking software

ultimate

to detect the CPU temperature.

and other important parameters, the general CPU temperature is too high, the computer will automatically shut down in order to protect itself, and check the power supply, it is not normal, the system does not want to work stably!

4. Then check it with software to see if there is a virus on the computer, such as turning on the automatic shutdown software, it is recommended to check and kill it all!
