What is the problem that the power supply of the computer is not on, and the power supply of the com

The power supply is very leathery.

I went home and bumped the main engine on the train for two provinces, and it was still turned on normally You see if the connection between your case switch and the motherboard is loose, whether the power supply and the motherboard are loose, and whether the socket has electricity.

Try again with a different power cord.

Excluding the above, it is not something that can be solved by individuals.

It may really be a problem with the power supply and motherboard, so you have to fix it.

See if there's a problem with your power outlet! The power supply is not working properly! Try it with a different board! If it still doesn't work, it may be a power supply problem!

I've also encountered this for you. It's a matter of the network card, just unplug the network card, right, if that's the case. It's good to change the network card...

Motherboard jumper issues. Back to the computer shop. Tell them to do it.

Power I fell 2 times. It's heavy, it's not bad, and Kanegawata's is even less fragile.

1.The main plug is loose.

Sometimes you accidentally touch the socket and plug of the computer, causing the plug to come loose and the computer will not turn on. You can check the plug area of the main unit and monitor.

2.Broken wires.

It is relatively easy to check if the plug is loose, but if the power cord is broken in the middle, it is difficult to check out, which is why we need to use an electric pen to check whether the test wire is energized. Check whether the wire is energized, and be sure to take protective measures.

3.The main switch is broken.

The host of the computer is a place that we often use, if you turn on the computer once a day, then you have to press it once a day, and it is easy to break over time, you can change a switch to test it.

4.The host power supply is broken.

The power supply of the host computer plays a role in stabilizing the voltage of the host computer when the computer is running. If the power is often cut off, it is easy to cause damage to the power supply, you can replace a power supply to test it.

5.There is too much dust inside the main unit.

Because in order to have good ventilation, there are many holes on the main unit, so the host of the desktop is the most prone to dust, and we have to clean it regularly, otherwise it will cause the motherboard and CPU to start poorly.

There may be several problems with the power supply of the computer host computer when it is not powered on:

1.The power plug is not plugged in properly or the plug is loose. You can check whether the power plug is plugged in tightly, or replace the power plug.

2.Power line failure. You can check whether the power line is damaged or short-circuited, or try to replace the power line.

3.The power switch is faulty. You can check whether the power switch is normal, or replace the power leakage and hunger grip switch.

4.Power failure. A power failure can be a damage to the internal components of the power supply that requires a power supply to be replaced.

If none of the above methods can solve the problem, it is recommended to contact a professional computer repairer for maintenance.

There are usually several possible reasons why the power supply of the computer is not energized:

1.The power supply is faulty. Loose power connectors, broken wires, blown fuses, etc. may cause the power supply to fail to supply power.

The solution is: check all Sakurajin power cables and plugs for loose or damaged ones, and reconnect or replace them; Check whether the fuse in the fuse box is blown or not, and replace it if it is broken.

2.The power switch is faulty. As a key component of power-on control, the failure of the power switch will also cause the computer to fail to power on. The solution is: check whether the power switch can work normally, and replace the power switch if there is any abnormality.

3.Motherboard failure. The motherboard is the control center of the computer, and if the motherboard fails, the computer will not be powered on.

The solution is: After troubleshooting the power supply and switches, if the computer still cannot power on, it is likely that the motherboard is damaged and needs to be repaired or replaced.

4.CPU overheating protection. An overheated CPU triggers the computer's overheating protection mechanism, cutting off the power supply to prevent the CPU from being nuclearized or damaged.

The solution is: shut down the computer and check whether the cooling module and fan are working properly; Restart your computer after a while, and if the power supply returns to normal, it may be caused by overheating. The heat dissipation module needs to be cleaned in time to prevent overheating again.

5.The memory module is faulty. Memory is also a critical component of a computer, and its failure can sometimes cause the computer to fail to turn on. The workaround is: After troubleshooting other hardware problems, try resetting or replacing the memory module with a different memory module to confirm if the problem is with the memory module.

Information received. You can unplug it and reconnect it to give it a try.
