Why does my computer stop after a few seconds of turning it on?

I've also come across situations where we discuss them in a variety of situations.

1.Most likely: memory issues.

Remove the memory, rub the gold finger repeatedly with a clean eraser, both sides, and then make sure that there is no power, plug it back, you can try to change the slot. If you still can't turn on after wiping it back, it is likely that the memory has been burned. My laptop was broken, but it was still under warranty, and I replaced it for free in between!

2.Possible cause: Motherboard.

Unplug all the wires on the motherboard and see if the joints are oxidized, and if they do, I don't know what to do, after all, I'm only in junior high school. Check it out on the Internet. Also, take a closer look to see if there is a black spot on the motherboard, and if it is, then congratulations, the motherboard is burning.

Hard disk. Remove the hard drive and shake it slightly. When the normal hard disk is shaking, you can't hear any sound, if you hear a sound inside, the sound is the friction between the head and the disk. Congratulations, too, the hard drive is rotten.

3.The least likely reason: CPU. If the CPU is broken, the motherboard will alarm you, and listen to it yourself to see if there is a tick sound.

If none of the above works, I'm helpless.

There are many reasons, such as insufficient voltage, if it is not very likely that the motherboard is burned out, it is a bad power supply that burns the motherboard, take it to repair, it can repair dozens of pieces, and it can not be repaired only by replacing the motherboard.

Check whether the switch is in poor contact, it may be that the switch is stuck, and also see if the CPU fan is connected, and this phenomenon will also occur when the power supply is overheated, check step by step!

You redo the system.,It's possible that the system files were lost by you.。。。

The reason why the computer will automatically power off in a few seconds after it is turned on is that the car is peaceful and the treatment plan:

1) The first reason: the power supply of the host is faulty, such as the filter capacitor of the power supply is bulging and leaking, resulting in insufficient power supply, it will form an automatic shutdown or restart of the computer, and the treatment method is to replace the power supply.

2) The second reason: The video memory integrated block of the graphics card is soldered, resulting in poor contact with the motherboard PCB board after powering on, it will automatically shut down or restart.

3) The third reason: the radiator falls off, and the motherboard detects that there is no cooling device, and the computer automatically shuts down due to the activation protection. Jianyi can open the main chassis and reinstall the radiator.

4) The fourth reason: the boot circuit of the motherboard is faulty, there is a problem with the power supply of the special CPU, the CPU cannot start, the motherboard starts the self-protection circuit, cuts off the power supply, and automatically shuts down. Jianyi repairs the boot circuit, especially the CPU power supply.

Old-fashioned CPUs may be CPU pins broken)

The power goes off a few seconds after the computer is turned on, probably because there is a problem with the computer's main unit, or the computer's power strip is not plugged in tightly.
