What happens when the computer turns off and then turns on automatically

Automatic power on after computer shutdown Solution:

1. First of all, check whether it is caused by hardware problems and the computer will automatically restart after shutting down, if you don't understand the hardware equipment, it is recommended to go to a professional computer maintenance point for maintenance and inspection, please do not disassemble it indiscriminately, otherwise the hardware equipment will be seriously damaged.

2. Check whether the computer is a spoof virus, use antivirus software to check and kill the virus, and repair the system.

3. Turn off the auto-restart function, right-click "My Computer" on the desktop, select "Properties" in the pop-up right-click menu, pop up the "System Properties" window, click the "Advanced" tab, and click "Start and Therefore".

The "Settings" button in the "Fault Recovery" column will pop up the "Startup and Fault Recovery" window. In the "System Failure" column, remove the checkmark before the "Auto Restart" option and click the "OK" button.

4. Turn off Advanced Power Management, click "Start Settings Control Panel Performance & Maintenance Power Options", and in the pop-up window, enable or cancel "Advanced Power Support" as needed.

1. Check the recently installed software, patches, plug-ins, and drivers to uninstall all of them, if the driver is not suitable.

3、The blue screen shutdown does not often appear on the boot,Boot press f8 to the advanced option to appear in the let go,Select "The latest correct configuration" Enter to repair,Restore the system or reinstall the system if it doesn't work。

4. If the hardware is caused by hardware problems, or the hardware is overclocked, the BIOS battery will be discharged (restore the BIOS factory default), it is recommended to plug and unplug the graphics card, memory and other hardware, clean up the hygiene in the computer, and polish the gold finger of the graphics card and memory (test whether the temperature of the hardware is too high).

There are probably several reasons for the automatic shutdown of the computer:

1. The heat dissipation is not enough, this reason may not be, because you are blowing the fan on the computer. It could also be that the protection temperature of your CPU is too low.

2. Due to memory reasons, when the memory is in contact with the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged in tightly with the motherboard.

3. Computer power supply problem, insufficient power supply is also an important factor that causes the computer to automatically shut down, and it is best to change the power supply for about 5 years.

4. Software factors, computer shutdown caused by viruses or Trojan horses is also normal. It's best to get an antivirus.

Check it out. 5. If the voltage in your area is unstable, or the voltage is low, it can also be automatically shut down, which is often the case here, especially in summer, and often automatically shut down at night. Low voltage.

Auto Shutdown Troubleshooting Methods:

1. There may be a problem with the BIOS settings, enter the BIOS to restore the default settings or take out the battery of the motherboard, reverse the buckle discharge, and wait for 5 minutes to reverse install it. Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2. If the computer is using a certain application.

If the automatic shutdown occurs when the software occurs, the automatic shutdown failure may be caused by the program software, and the program software can be uninstalled.

3. Then check the power supply, the power supply quality is poor, aging or the power is too small, which can not meet the power supply needs of the computer accessories, and the high-power and high-quality power supply can be replaced.

4. Then use the elimination method to check the memory, graphics card, CPU, CPU fan, motherboard, etc.

5. Check the memory, the memory quality is not up to standard, poor heat dissipation, overclocking, mixing and inserting of different brands of memory and the CAS value setting is too low, etc., which can cause the computer to shut down automatically, and the memory parameters can be adjusted accordingly in the BIOS.

6. Check the motherboard, the motherboard aging, capacitor failure or bursting, the motherboard power pins, the motherboard and the chassis backplane short-circuit, etc. can cause automatic shutdown, you can take the motherboard out of the chassis to check or test, and then check whether the CPU fan rotation and CPU temperature are normal, and then check the CPU fan heat sink.

If it is dry, clean the silicone on the CPU fan and reapply the good silicone. If the fan is not normal, replace the CPU fan.

7. Cleaning method: It is a method to eliminate faults by cleaning the dust of the parts in the computer host. Dust is one of the factors that can also cause computer automatic shutdown failures, dust can cause parts aging, pin oxidation, poor contact and short circuit and other failures.

For these faults caused by dust, it is generally more effective to use the cleaning method.
