Why does the computer automatically shut down and what to do

The problem of automatic computer shutdown can be divided into two kinds, the first is the problem of software, such as viruses or some wrong programs when executing programs** can cause automatic shutdown. The second situation is hardware problems, such as the CPU or graphics card chip, motherboard chipset is too high temperature, which will cause the hardware to automatically protect the shutdown phenomenon, and there is also the possibility of aging of the internal components of the power supply or damage to the motherboard power supply components.

The easiest way to deal with the software is to format the entire disk and reinstall the system and software, or pay attention to it slowly, and then uninstall the software and reinstall it.

The processing method of the hardware is to enter the BIOS first, and see if the setting of the automatic protection temperature in the PChealth item is too low, because when the hardware temperature reaches the value you set, the computer will automatically protect and shut down, if there is no problem with this, just look at the situation of the heatsink and fan of your CPU and graphics card, whether the silica gel between the CPU and the heatsink has dried up, whether the fan has been aged, etc., if these are all right, It is recommended that you use the elimination method to replace the power supply, motherboard, and CPU in the same way.

The computer shuts down automatically, why? How to solve it?

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated and whether the CPU fan holder is stable, if it is broken.

Or it is unstable, the CPU fan cannot be suppressed, the CPU fan has insufficient heat dissipation capacity, and the CPU temperature is too high, and the motherboard's automatic protection function will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to use 360 Antivirus 360 Security Guard to repair it in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

The computer shuts down automatically, why? How to solve it?

1.Poor heat dissipation: The monitor, power supply, and CPU generate a lot of heat during work, and working for too long will also cause the power supply or monitor to dissipate heat poorly, resulting in computer crash.

2.Reason for moving: During the movement of the computer, it is often loosened by the internal components of the machine, which leads to poor contact and computer crash.

3.Excessive dust in the machine can also cause crashes. If the floppy drive head or optical drive laser head is contaminated with too much dust, it will lead to reading and writing errors, and in serious cases, it will cause the computer to crash.

4.Device mismatch: For example, the main frequency of the motherboard and the CPU clock do not match.

5.Software and hardware are incompatible.

6.Loose memory modules, virtual soldering, or quality problems with the memory chip itself cause the crash.

7.The hard disk is aging or due to improper use, resulting in bad sectors and bad sectors. In this way, the machine is prone to crash while it is running.

8.The memory capacity is insufficient.

9.Inferior parts.

10.Viruses can dramatically reduce computer productivity and cause frequent crashes.

11.There is too little space left on the hard drive or too much fragmentation.

12.There are too many programs to start, which exhausts system resources, so that the data required by individual programs cannot be found in memory or virtual memory, and abnormal errors can also occur.

13.Illegally opening or releasing programs in illegal formats or parameters can also cause computer crashes.

The computer shuts down automatically, why? How to solve it?

Reason for automatic shutdown of the computer:

1.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).

2.When the core components of the system are damaged, the running computer may automatically shut down. Kingsoft security experts are here to provide you with special killing tools and system repair tools, please click Fast**.

3.In the running software, there are some software with the option to shut down when the task is completed, and the user may not have noticed and turned these switches on.

These software are more common, such as Thunderbolt, Express, anti-virus software, 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.

The purpose is to automatically shut down the computer when a task is completed when a task is running a more time-consuming operation.

4.Other hardware reasons.

The solution to the automatic shutdown of the computer:

1.First of all, check whether there is a problem with the hardware, focusing on the power supply of the motherboard, CPU fan, host power supply, and power socket.

2.Check if there are some applications that have enabled shutdown after the task is completed. This is evident from this. The feature is that before shutting down, there will always be a program that has been run, and a dialog box will generally pop up to remind you to shut down.

3.Resolve virus Trojans and repair system damaged files. With the latest version of Kingsoft Antivirus 2011, you can complete virus removal and system configuration repair at one time. "

The most important thing is the voltage, or it could be too much dust, if not these two reasons, try reinstalling the program.

Because it's a computer, it's smart, and you can shut it down by yourself without having to do it by yourself!

See if it's who gives the settings to the automatic power on/off.

The computer shuts down automatically, why? How to solve it?

After automatic shutdown If it can be turned on normally, then this situation belongs to the self-protection function of the system.

Because there is an automatic power-off protection function in the motherboard BIOS settings, that is, when the computer is overloaded or encounters other situations that damage the CPU or system, this information will be fed back to the motherboard chip in time and react, because the BIOS is set up with this protection function, so in order to protect the CPU from damage, the system will automatically power off.

Your computer should be cleaned of dust or the fan is not running well, which usually occurs when the CPU is overheated or the CPU is overloaded due to the computer running for a long time. Excessive dust and improper fan operation will lead to poor heat dissipation and overheating of the CPU, which will trigger the automatic power-off protection function. If that's the case, just fix the heat dissipation problem!

If the computer cannot be turned on normally after power failure, it is estimated that there is a problem with the hardware or system files.

First, use the replacement method to troubleshoot the hardware problem (mainly check the motherboard and power supply).

After the hardware is eliminated, it is a system problem, and it can only be solved by reinstalling the system.

Frequent automatic power outages can cause harm to computer hardware, and the consequence is to shorten the life of the hardware.
