Hello everyone, Lin Fei to answer the above questions, win10 computer automatically restart after shutdown, computer automatic shutdown restart is what many people do not know, now let's take a look at it!

The reason why the computer shuts down automatically:

First of all, software

1. Virus destruction. Soon after the computer appeared, the computer virus appeared. When the network has become the main artery of information in today's society, the spread of the virus is more convenient, so it interferes with and destroys our normal work from time to time. A typical example is the "shock wave" virus, which caused serious damage to computers around the world some time ago. When it attacks, it will also prompt the system to start automatically after 60 seconds. In fact, as early as in the era of DOS, many viruses can restart computers automatically.

Whether it is damaged by the virus or not, we can use the latest version of the antivirus software for antivirus. The virus is usually found. Of course, there is also a possibility that someone maliciously intruded into the computer when surfing the Internet and placed Trojans. In this way, the other party can remotely control all the activities of your computer, including restarting the computer. For some Trojans, it is not easy to clean up, it is better to reinstall the operating system.

two。 The system file is corrupt. When the system files are destroyed, the basic files such as KERNEL32.DLL under Win2K and fonts under Win98 FONTS directory are destroyed, and the system will be forced to restart when it starts. You can do an experiment by renaming fonts in the WIN98 directory. When the computer is turned on again, the computer will turn on again and again. For this kind of failure, because the normal desktop cannot be accessed, it can only be installed or reinstalled.

3. Timing software or mission planning software works. If you set up a restart or load some working programs in the Task Planning Bar, the computer will start again when the time comes. In this case, you can open the Startup item, check whether there are unfamiliar execution files or other scheduled working procedures, and then block it before starting the check. Of course, you can also start it by typing the "Msconfig" command directly into "run".

Second, hardware

1. The power supply voltage is unstable. In general, the working voltage range of household computer switching power supply is 170V-240V. When the power supply voltage is less than 170 volts, the computer will restart or shut down automatically. Because sometimes can not feel the fluctuation of the electricity voltage, will be mistaken for the computer inexplicably automatically restart.

Solution: for areas with unstable power supply, you can buy UPS power supply or 130-260V wide switching power supply to ensure the stable operation of the computer.

two。 Poor quality of jumpers or power sockets and poor contact. Most of the power patches on the market are of poor quality. The internal contacts are welded by hand, and acid flux is often used, which can easily lead to oxidation of solder joints, resulting in open circuit or leakage between hot wire and zero line. Because of manual welding, and because of the poor elasticity of phosphorus brass, it will lose elasticity in a short time, resulting in poor contact with the power plug of the host or display, resulting in large contact resistance. Working long hours will generate a lot of heat, which will lead to false connection. The host is rebooted or the display is flashing black.

Another possibility is a wall outlet for home use. Most wall sockets are not installed by professionals, so the wiring inside the sockets is very irregular. In particular, if we often use high-power electric heaters in these sockets, it is easy to cause internal heat, oxidation, virtual connection, intermittent power outages, computer restart or monitor flicker.

Solution: instead of finding ways to save money, it is better to buy cheap and inexpensive patch boards and some famous brand plug boards, because they are all automatically installed and crimped by machines and do not need manual welding. For the problem of virtual connection inside the wall socket, you can try to replace the mainframe with the wall socket to see if there is the same automatic restart problem.

3. The computer power supply is insufficient or the performance is poor. This situation is also common, especially after adding new equipment to your host, such as a premium graphics card, a burner, and a hard disk. When the host is working at full speed, such as running large 3D games, burning CDs at high speed, or preparing to read CDs, dual disks may copy data at startup, which may cause power protection to stop output due to transient lack of power supply. However, when the power supply stops output, the load is reduced, and then the power supply is started again. Because the recovery time after protection is very short, it shows that the host restarts automatically.

On the other hand, the performance of the host switching power supply is poor. Although the voltage is stable and within the normal allowable range, the harmonic content in the output power supply is too large, which will lead to frequent mainframe crashes or restarts. In this case, it is normal for us to test its voltage with a multimeter. Better get a good power supply.

Solution: now replace the high-quality and high-power computer power supply.

4. The mainframe switching power supply plug is loose, the contact is bad, and the plug is not tight. Most of these situations will occur on the DIY machine. The power cord of the mainframe power supply is not certified by 3C and does not match the power outlet. When shaking the table or touching the mainframe, the mainframe automatically restarts, usually accompanied by a slight flapping of the light.

Solution: replace the high-quality 3C certified power cord.

5. Motherboard power supply ATX20 socket virtual welding, poor contact. This kind of failure is not common, but it does exist. The main thing is to move the ATX20 pin plug left and right when the host is working normally to see if the host will restart automatically. At the same time, check whether the Reed inside the 20-pin power plug is oxidized, which can easily lead to large contact resistance, poor contact, and lead to the mainframe crash or restart. Sometimes, it is necessary to check that the cable at the end of the 20-pin plug is secure.

Solution: if the motherboard is a virtual solder joint, just fix it with electric iron. Note: when welding motherboards, hard drives, graphics cards and other computer boards, be sure to ground the soldering iron correctly, or pull the power plug when welding. If it's the power supply, you'd better change to a good power supply.

6. a central processor

Solution: try to block the second-level cache (L2) or the first-level cache (L1) in CMOS to see if the host is running properly, or simply replace it with a good CPU. If it can operate normally after shielding, it can still make do with it. Although the speed is slower, it will save money.

7. Memory problems, if a chip on the memory bar is not completely damaged, it is likely to pass the self-test (most of them must be set up with POST), but it will restart unexpectedly due to the failure of the function caused by the high heat generated by the memory at run time. Most of the time, when the memory is damaged, the alarm will be turned on, but if the memory is damaged, there will be no alarm, and there are still faults that do not power up. It is best to use the elimination method, which can quickly determine the fault location.

8. Optical drive problems, if the optical drive internal damage, will also cause the host to start slowly or fail the self-test, or it may be a sudden restart in the course of work. For the latter case, if we replace the optical drive, it is likely to be caused by the different power consumption of the optical drive. What you need to understand is that although the ATPI interface of the optical drive is the same, the pin definition of different manufacturers is different. If there is a problem with the hard disk line, there may be no problem with the use of a certain brand of optical drive, but it is impossible for other brands of optical drive to work, which requires attention.

There is a problem with the quality of the 9.RESET key. If the RESET switch is damaged and the internal Reed is always in the short position, the host will not be able to power on self-test. However, when the elasticity of the RESET switch weakens or the button on the chassis is not easy to pop up, it will appear in the process of use, because of occasional touch of the chassis or sudden restart of the host computer under normal use. Therefore, when the RESET switch can not press freely, be sure to check carefully, it is best to replace the new RESET button switch or lubricate the external button of the chassis.

There is also a situation, because the RESET switch leads in the chassis are peeled off too much during welding, coupled with the repeated unpacking in the process of use, it will cause the RESET switch lines to be too close and cause collisions, resulting in the host restarting automatically.

10. Access to the network card or parallel port, serial port, USB interface to access external equipment automatically restart, this situation is generally due to external faults, such as printer parallel port damage, a foot to ground short circuit, USB equipment damage to ground short circuit, network card workmanship is not standard, when using these devices, it will cause computer restart because of sudden power short circuit.

Reason 3. Other reasons

1. Poor heat dissipation or temperature measurement failure, CPU poor heat dissipation, frequent problems are CPU radiator fixed clip falling off, CPU radiator and CPU contact between foreign bodies, CPU fan after long-term use of the radiator dust too much, these cases will lead to CPU poor heat dissipation, accumulation temperature is too high and automatically restart.

In addition, the temperature measurement probe under the CPU is damaged or the temperature measurement circuit inside the P4 CPU is damaged, and the BIOS on the motherboard has BUG temperature measurement inaccurate under some special conditions, which will cause the host to restart automatically during the working process. Finally, if the CPU protection temperature set in CMOS is too low, it will cause the host to restart automatically.

two。 Fan speed measurement failure, when the CPU fan speed circuit damage or intermittent disconnection of the speed line, because the motherboard can not detect the fan speed will be mistaken for fan shutdown or restart automatically, but the inspection may see that the CPU fan rotation is normal, and the speed measurement is also normal.

3. Strong magnetic interference do not underestimate electromagnetic interference, many times the computer crash and restart is also caused by interference, these interference not only from the chassis internal CPU fan, chassis fan, graphics card fan, graphics card, motherboard, hard disk interference, but also from external power lines, frequency conversion air conditioning and even automobiles and other large equipment interference. If the interference performance or shielding of the host is poor, the host will restart unexpectedly or crash frequently.

At the end of this article, I hope it will be helpful to you.
