What is the reason for my computer to shut down automatically?

The reason for the automatic shutdown of the computer:

1.Poor heat dissipation of the host, which is the most common one, is mainly manifested as: abnormal computer sound, such as the sound of a fan turning; There are burnt marks on the motherboard and other accessories, or there is a burning smell on the motherboard; The temperature of major components such as the CPU, such as the temperature of the CPU, is too high.

2.Virus Trojan damage, if there is a virus Trojan intrusion, then the core components of the system will cause damage, at this time, the computer is likely to shut down automatically.

3.The impact of running software, many software will have the operation of automatically shutting down after completing the task in the settings, the common ones are Thunderbolt, Express, anti-virus software, etc., mainly because this kind of software is relatively time-consuming, so it will automatically shut down the computer after completing the task.

4. Procedural problems, some programs will often produce automatic shutdown in use.

5. If there is a problem with the BIOS settings, go to the BIOS to restore the default settings, and then eliminate the automatic restart or shutdown of the BIOS heat dissipation preset.

6. Power failure, this kind of situation is often generated in the case of excessive system load, the load is too large, the operation of the hard disk and CPU is aggravated, and the power supply can not withstand the sudden increase in voltage, the computer will shut down by itself, and a higher power supply is needed.

7. Excessive dust in the chassis, the computer will be used for a long time, which will cause excessive dust in the chassis, which will cause the motherboard to short circuit or poor heat dissipation, and then cause the computer to shut down automatically.

8. High indoor temperature, high indoor temperature, especially in summer, and long-term running of large-scale programs, such as 3D large-scale online games, etc. The solution to the automatic shutdown of the computer:

1. Install Master Lu and other software to monitor the various conditions of your computer from time to time; Pay more attention to accessories such as computer exhaust fans.

2. If you find that there is a virus Trojan intrusion, you should apply antivirus software for antivirus in time, and put it in antivirus software.

3. When running anti-virus software, express trains, etc., pay attention to their settings, because many of them are tacitly set, and they will automatically shut down after completion.

5. For BIOS settings, just go to BIOS and restore the default settings.

6. Indirectly, the power failure is also caused by the operation of the system, and in this case, it is necessary to replace the high-power power supply to ensure its demand.

7. Dust will cause parts aging, pin oxidation, poor contact and short circuit and other failures, so the computer should be cleaned regularly.

8. When using the computer, pay attention to the environment; At the same time, do not turn on the computer for too long at once or run large software at one time.

Hello, it is recommended that you first use the system first aid kit to check and kill 1 virus, and then use Master Lu to see if the temperature of the hardware is too high, if these two aspects are normal, you can reinstall the system 1 at your discretion, if it will be shut down or restarted frequently, the problem may appear on the computer hardware, it is recommended to go to the after-sales or repair shop for testing.

Task Manager has malicious program tools.

This can break the program's startup items.
