The computer power does not start, and the computer power does not respond when it is turned on

You can first determine whether the power supply is really broken First unplug the end of the power supply connected to the motherboard, use a binding wire or needle-nose pliers (conductor is OK), one end is plugged into the green wire hole connected to the power supply and the motherboard, and the other end is plugged into any color hole, and the power supply is connected If the power supply fan turns, it means that the power supply is not broken, if it does not turn, the power supply is broken

If it's not a broken power supply, I think, it's a broken motherboard

You can also unplug each piece, one by one, and eliminate it to see what is missing when the computer can work

I know, that's all there is to it, and I hope it can help you a little

It is estimated that the northbridge chip of the motherboard is broken. You can't get it right. My computer got a different motherboard for this.

If you can enter the BIOS, you may not be able to enter the BIOS, and the BIOS of the motherboard may be broken.

Is there an alarm? Or check out the main version.

It is normal for the mouse to be bright, even if the power supply is broken, it will also be bright, and the CPU fan will also turn, because the voltage does not need to be high to drive them, of course, it is not necessarily that the power supply is bad, and the motherboard is also very likely. Pay attention to check and see, there is no dripping sound, do you see if the motherboard is lit up? If the hard disk is rotating, there is nothing wrong with the power supply.

What do you know about the following things? Dust removal is also necessary, but now I guess it's the motherboard's business! Good luck.

Your phenomenon can only mean that the motherboard may not be broken, check it with the hardware detection card, it may be a problem with the CPU, the general CPU and memory, and the graphics card do not like to be bad! The power supply may not be broken, because the other hardware indicators are on!

See if the connection between the motherboard and the switch has fallen off, you are likely to have lost your feet twiceHehe, it seems that you are also a little grumpy!Hehe

Is there a problem with the cable adjustment of the motherboard!

It may be the main version, but first check to see if your phase power supply is broken.

The computer boot power does not respond to this, first of all, check whether your power connection socket and your computer connection is normal, if it is normal, the computer will respond after clicking the boot button, if there is still no response, then your computer may have a problem to the computer maintenance department to check.

2.In addition, if the computer case has been turned on, but the display screen is still black, then it is possible that the power supply of the display is not connected or there is a problem with the connector connected to the computer case,..

3.If there is no problem with the above, then it may be that there is a problem with the motherboard wiring, then we need to send it to a computer repair shop for a professional to overhaul it.

Ask if the motherboard is broken, whether it should be repaired or replaced.

Repair** is too expensive, it is recommended to replace it.

Share how to disconnect the power supply and determine whether it is a motherboard failure or a power supply problem.

The system does not boot at all, the power indicator is not visible, and the cooling fan is not heard. Part, it can basically be regarded as a power failure, check: whether the power cord and plug are powered, the motherboard power plug is connected, and whether the power supply is normal.

UPS power failure confirmation, the easiest alternative, but ordinary users may not have spare parts and other powers at home, you can try to use the following method (note: be careful):

Hard disk, CPU fan, disc or better, then ATX motherboard power plug with two pins connected with wires (pimple against his plug, the upper pin from the left number 4th and the low pin from the right number 3rd, the direction must be correct).

Then turn on the ATX power switch, if the power supply fan rotates, the power supply is normal, otherwise the power supply is damaged. If the power supply can be connected directly to the power switch on the motherboard, if it is normal, it will damage the power switch of the cabinet panel.

The motherboard can not use the keyboard interface, unplug the keyboard, and then reinsert it to start the system normally, after using it for a period of time, the keyboard does not respond, this phenomenon is mainly caused by repeated loosening of the motherboard keyboard keyboard interface, delete the good motherboard welding;

It can also be a live plug-in keyboard that will block the fuse plug on the motherboard (with a marked fn on the motherboard) and replace it with a resistor of 1 ohm watt.

The computer power can't start and can't turn on the situation that many friends should have encountered, so what's the problem of? How do we solve it? Some users don't know much about it, so today I'm going to sort out and share with you how to deal with the power that doesn't turn on the host.

Here's how to deal with it:

1. Unplug the power plug, then press the power switch of the computer, release the remaining power in the host, then turn on the power and restart the machine (if it is invalid, turn to the next step, the same below);

2. Open the chassis and wash and dry your hands with water. Unplug the memory module, and turn it on and off, plug in the memory module again, and turn it on;

3. Unplug the graphics card, then replug it in and connect the graphics card and monitor, and turn it on;

4. Unplug the hard disk data cable and power cord for modification, power on and off, plug in the data cable and power cord again, and turn on the computer;

5. Find the motherboard battery and remove it carefully. Mott uses great force to prevent the tool from scratching other parts, short-circuit the two contacts of the battery on the motherboard (not the positive and negative poles of the battery), power on and turn on, and then put the battery back in place and turn it on;

6. Disconnect the host from other (display) components, turn on the host to observe the hard disk light, etc., to see if the host is running;

7. Find experienced people to deal with it;

It's likely that your computer's power supply is malfunctioning or that the power cord is not in good contact.

First of all, check whether the contact between the power cord and the computer is good, if the power cord is loose and leaking, etc., you can replug and unplug or replace the new power cord.

If you rule out the contact problem with the power cord, it is likely that there is a problem with your computer's power supply and you need to replace it with a new one.

PS: Many friends often ignore the importance of computer power supply when pursuing computer with shouting, I hope you try to choose a big brand guaranteed power supply when buying a computer power supply, so as to make the computer run more stable.

Summary. If the power supply is abnormal, plug and unplug the power cord of the host.

If the circuit of the motherboard BIOS is abnormal due to a sudden power failure, you can release static electricity to the motherboard.

If the system hard disk self-test is caused by an abnormal power failure, it will automatically enter the system after waiting for a period of time.

If the computer blue screen is caused by an abnormal power failure, you can choose the last correct configuration, or enter the safe mode to repair the system files.

The power is not turned off, and the computer cannot be started again.

Hello, what do you say?

It depends.

Haven't you started yet?

No, you have to wait for the power to be turned off for 5-6 hours, and then turn on the computer to turn on normally, before the power was turned off for 3 hours, because the power strip was not turned off with an electric mattress.

You say it's the power supply or the motherboard.

Does this happen all the time.

Often. There is a high probability of static electricity problems on the motherboard.

How long has the computer been bought, what brand.

After-sales service is available.

Ten years, assembled.

Thank you.
