The computer won t turn on, and the host computer doesn t respond?

What should I do if the computer does not respond after pressing the power button? What is the problem that the computer cannot be turned on after pressing the power button? Recently, several users have reported that the computer has not been able to turn on normally after pressing the boot button, and the following will give you an analysis of the specific reasons and solutions.

Maybe it's because of the old wiring, either turn on the host computer to see the wiring, or let the computer rest for a while, and then plug it in again and turn the computer back on!

If your power supply is not very expensive, it is recommended not to repair it, and replace it directly.

The first thing to determine is whether it is a problem with the power supply.

1. Power socket problem. The first bai must first exclude the external factor of du, and sometimes the plug is loose, dao

The computer is not powered back at all, so the first thing to check is that all the answer plugs are powered on.

2. Memory module. If you can't turn on the phone, many times it is because there is a problem with the memory module, especially the machine that has not been used for a long time. Open the main chassis, take out the memory module, wipe it, and then put it back on.

3. CPU fan. The CPU fan is not working, which causes the CPU to be unable to dissipate heat and naturally cannot be turned on. Open the case and see if the CPU fan is blocked by other parts such as wires.

If not, press the power button again, if the CPU fan does not rotate, it is broken, and then you have to replace it with a new one.

4. The power supply is broken. There is also a great possibility that the power supply is broken, if the above problems are ruled out, then it is very likely to be this problem. The main reason for a broken power supply is due to unstable voltage.

That's when your host is broken, get it to repair the computer** to help you get it, they have special detection tools that can help you detect what is broken.

1. Your CPU fan dissipates heat.

Is it normal? Whether there is too much dust inside the machine.

2. Is there a problem with the motherboard? Because if the motherboard has a loose circuit, then the current or data will not be transmitted correctly. You can loosen the motherboard set screws to avoid the motherboard being unstable due to the deformation of the motherboard caused by the screws being fixed too tightly.

3. Caused by power supply or motherboard. Because the power supply is damaged, its power supply is unstable.

Do you pass the POST? If there is no response and no sound, check the CPU, check the graphics card with a long and two short screams, and check the memory with a sound.

Does the case fan turn? The power light of the chassis is on.

system? If the fan is turning, check the motherboard, graphics card, and memory.

If the fan does not rotate, check the case power supply, motherboard, and chassis boot buttons. and chassis power cables and power strips.

There are also many cases where the case power light is on. It's more complicated. If you don't get it right, you can send it to the after-sales service.

The host didn't react at all.,Right?,I'm having this problem now.,It's recommended to fix it.。

Is the line connecting the monitor and the main unit checked? Is it plugged in?

How to solve the black screen of your computer:

1. Check the display.

Whether the cable between the indicator and the computer is tightly installed;

2. Take off the inner and lower computer memory sticks and use oak.

Rongpi wipes the gold finger and puts it back (poor contact will cause the computer to boot up with a black screen);

3. Replace the memory, graphics card, display, and cable to diagnose the fault.

4. If the system file is damaged, use [U Boot U Disk Boot Disk] to reinstall the system.

Clean and maintain the memory, graphics card, and power supply (it is best to do the following things after self-testing) If you can't enter safe mode (reinstall).

If you can enter, go to full mode, antivirus and system repair.

Scan all disks for logical errors.

If this is not the case with the system (reinstall).

When you say you can't start, you mean copy

That aspect? Yes, there is no display when it is turned on.

Still can't get into the desktop, still no power. There is no display at startup, please observe whether the cable is connected, or open the host to see, there are no obvious burnout marks on the motherboard, if it is normal, you can remove the memory and clean the gold finger part with a rubber sassafras. Or directly don't go to the memory to see if there is an alarm, see if you ask this kind of question, because it should also belong to the contact with this is not very in-depth, if the above is still not recommended to find someone who understands.

Most of the reasons why you can't enter the desktop are due to system reasons. You can reinstall the system and see. If there is no power on, then you have to check whether there is power to the host, if there is you, you have to look at the power supply, we generally test the power supply is to short the green and black wires of the power supply, to see if the fan will turn, generally a good power supply will turn.
