How to solve the sudden pause of the computer, it is useless to turn on the key

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 shuts down automatically when using a certain application software, the automatic shutdown failure may be caused by this 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 pulp, the motherboard power pins, the motherboard and the chassis backplane short circuit can cause automatic shutdown, you can take the motherboard out of the chassis to check or test, then check whether the CPU fan rotation and the CPU temperature is normal, and then check whether the bottom of the CPU fan heatsink is dry, if it is dry, clean the silicone on the CPU fan, and then recoat 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.

8. The power supply system is unstable, which can also cause the occurrence of automatic shutdown faults, and a UPS backup power supply with voltage stabilization function can be considered.

This is a problem with the heat dissipation of the notebook, and there are several possibilities. First, there is a problem with the thermal design of the notebook, which is congenital and cannot be solved, so they can only consider themselves unlucky, and they can't solve it if they go to repair it; The second is: due to the use of a long time, such as eleven months, twelve months, anyway, there are still a few days to exceed the warranty period, this problem, this situation is like the reason for the face, there is a problem with the heat dissipation of the notebook caused by dust, this situation is often as long as it runs, such as online games and other heat dissipation is relatively large, there is an automatic shutdown, this situation is best sent to the maintenance department, please help you do the division, to remove in front of you, on the one hand, you can learn it, On the other hand, it is to prevent maintenance personnel from changing memory modules and other things for you (now people, the heart of harm must not be there, and the heart of preventing people is indispensable); Third, the system is heavily poisoned!

This situation is easiest to deal with, reinstall the system, and then disinfect the virus.

Analysis of the reasons why the computer cannot shut down normally:

1.Caused by Trojan viruses.

The sound file is corrupted and the computer cannot be shut down.

Incorrect settings will cause the computer to fail to shut down properly.

4.The Advanced Power Management (APM) feature on your computer can also cause shutdown, freeze, or black screen issues.

It means that there is a problem with your computer. Find a computer expert or an expert to help you fix it (you can also use some software).System reinstallation is the one-size-fits-all solution to a problem with your computer (your computer's hardware isn't damaged).

Generally speaking, shutting down a computer abnormally is harmful to the computer (usually not directly manifested).

The icon becomes larger when Safe Mode is turned on because Safe Mode works by booting the computer without loading third-party device drivers, so that the computer runs in the minimum mode of the system, so that users can easily detect and fix errors in the computer system. Safe Mode automatically disables all non-system startup items, freeing Windows local control over these files. The size of that icon is related to other software.

It should be that the CPU bracket is broken, and that thing is only a few dollars, so buy one and replace it yourself.

Is it caused by CPU overheating.

A lot of such questions? But isn't it always okay?

I think it's very likely that the fan is broken, or it's poisoned, and it's unlikely otherwise, so I suggest you take it apart to see if the fan is running.
