The computer turns off automatically when it is turned on.。。 The master asks for help

Check if the monitor cable is loose Check if the graphics card is damaged If there is an onboard graphics card, it is recommended to remove the discrete graphics card and try it.

Has the machine moved, has it been installed, has anyone moved the CMOS?

If nothing has been moved, it is estimated that there is something wrong with which part, and whether you heard the long and short dripping sound when you turned on the machine, such as two long and one short, two short and one long. Judging by this voice, something is wrong.

However, in general, this situation is mostly a problem with memory or graphics card, and the way to replace these two pieces first is to find out what is wrong. If it's not memory or graphics card, check the CPU again, and then the motherboard.

If you change the environment, it's okay, it's caused by voltage instability.

Generally, the automatic shutdown may be caused by too much dust in the CPU fan, so it is recommended to clean up the dust on the CPU fan and heat sink and add new heat dissipation grease. If it is not a problem, it may be caused by problems such as motherboard parts or power supply, voltage instability, etc., if you can't find out the reason, it is recommended to repair it, because automatic shutdown is not a small problem. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

If the memory module is loose, unplug it, wipe the gold finger with an eraser, and then insert it back in, if it doesn't work, repeat the process.

Dust the case and clean it up well It's really not good to do the system It's simpler If it's already turned on and shut down in about 10 seconds, it means that the CPU is overheated I've encountered it, but I don't know if our request is the same.

Auto Shutdown Troubleshooting Methods:

1. There may be a problem with the BIOS settings, go to the BIOS and restore the default settings.

2. If the computer shuts down automatically when using a certain application software to return to macro, the automatic shutdown fault 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 substitution method to check the memory, missing notebook graphics card, CPU, and motherboard.

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.

Half of the words make people guess? Leaky shed?? What kind of information ?。。 Now how can people not even know how to ask questions?

It's like saying you want to eat, I know you want to eat, why do you want to eat?

You rebuild the system.

Send it to the factory to repair it, isn't it a good idea, give some points, hahahahaha.

1.: Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.: Memory reasons. When the contact between the memory and 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, or you can change the socket to see if it is down.

3: Check whether the CPU is overheated, whether the CPU fan holder is stable, if it is broken or unstable, it can't hold down the CPU fan, the CPU fan has insufficient heat dissipation capacity, the CPU temperature is too high, the automatic protection function of the motherboard will automatically shut down, and the CPU fan screws are loose!

4: It may be caused by the unstable voltage of the host, just replace it with a high-power power supply.

It may be that there is too much dust on the fan, which causes the automatic shutdown, and it is normal to clean up the dust!

Most of them are caused by the failure of the CPU cooling fan or bracket, which causes overheating, and the motherboard's self-protection power is cut off. Solution: Check whether the CPU cooling mechanism is loose and whether the fan is normal.

Experienced the problem, the key is broken, and it is easy to weld to death when pressed. Solution: Change the button, or tap it to see if it pops back.

If you preliminarily judge the power supply problem, you can consider changing to a high-power power supply to try.

You can basically confirm that it's a fan problem, no, and see if the fan has any strange sounds.

Can you be more specific? For example, what brand it is, the voltage on his side is not 、、、

Is it that the voltage in his house is unstable?

Oh, that's because you have a problem with your computer.
