The computer will automatically shut down if it doesn t turn on

Auto Shutdown Troubleshooting Methods:

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

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.

Generally, this situation is due to the motherboard, memory or power supply, so it is recommended that you try them one by one. If you don't have the conditions, it's best to take it to the computer city for testing.

There can be a variety of reasons for the problem of your computer automatically shutting down shortly after it starts, here are some possible ways to fix it::

Clean up the dust inside: Too much dust can cause your computer to dissipate heat poorly, which in turn can cause your computer to shut down automatically. The inside dust can be cleaned using a vacuum cleaner or compressed air canister.

Check the power supply: A power failure can also cause your computer to shut down automatically. You can replace the original power supply with another power supply for testing, or use a power supply tester to measure whether the output voltage of the power supply is normal.

Check the radiator: A malfunction of the radiator may also cause the computer to shut down automatically. You can check if the CPU heatsink is installed correctly and if the fan is working properly.

Check your hardware: Hardware issues can also cause your computer to shut down automatically. You can check whether the memory module is loose or damaged, whether the graphics card is normal, whether the hard disk has bad sectors, etc.

Check your system settings: Some computers shut down automatically due to problems with your system settings. You can disable the option to automatically shut down in the system settings, or reinstall the system.

If the above methods do not solve the problem, it is recommended to contact a professional computer repair personnel for repair and repair.
