My desktop computer won t boot for no reason

Personally, I think it's because the data circuits on your motherboard are in poor contact, or there is too much dust and static electricity in the host. Because your computer basically doesn't touch it under normal circumstances, it stores a lot of static electricity at this time; When you take it to the maintenance point, you move, touch, and open the chassis again when you get there, so that the static electricity in the chassis can be discharged, and the main unit becomes normal again.

Suggestion: Connect a ground wire to the main unit, connect one end to the rear face plate of the chassis, and insert one end into the hole of the ground wire in the middle of the three-pin socket.

The possibility of a problem with the power supply is relatively small, and it is more like a board card and a poor contact with the data cable.

Most of your questions have something to do with power strips!

The refrigerator is a large power consumer, and it interferes with other electrical appliances, so it is recommended to lead the refrigerator line to other places to try it!

Is the power supply at your home not very stable? Check if the voltage is low.

The line contact of the button is not measured.

Look at the offline is there a problem...

It should be possible to do what was said upstairs, or unplug the power supply and plug it in after a while. If it's mostly a motherboard problem.。。 But it's the specific problem of the motherboard, I don't know very well.

I've been in this situation before. Okay, all of a sudden, I can't open it, pull it out, and it's good again after a while. Later, I changed the board.

If the warranty period has not expired, it is recommended to find them to replace the motherboard.

1 There is a problem with the power supply.

2 Switch issues.

Maybe you've had a power outage in your home.

Let's not talk about that, let's talk about the solution.

If you have this problem, you can unplug all the power cords, unplug the power button on the computer, and press the power button on the computer, in order to release all the static electricity, and then solve the problem of powering on.

Do not share an outlet with a refrigerator on your computer.

Is there a problem with your home's power supply?

If the computer fails to start pressing the power button, check the circuit and the power supply of the computer if the computer is not powered on, open the side panel of the computer for inspection, disassemble the side panel of the computer, take off the memory module, and wipe the metal contact point of the memory module with alcohol, which can prevent the computer from not starting due to poor contact of the memory module. If it still can't be turned on, it may be another hardware problem and should be sent for repair in time.

Questions. The battery is flashing.

I'm sorry to sort out the answer for you, I hope you understand.

If the flashing can't be opened, it's a hardware problem, and you can't repair it.

Questions. Thank you.

You're welcome to thank you for your support

1. First of all, we can check whether there is a power switch failure, which may cause the power switch button to be pressed and cannot be reset due to the aging of the switch button, resulting in the phenomenon of not being able to start normally.

2. It may be that there is a fault in the memory, if there is no normal start-up sound when the machine is turned on, and there is no memory alarm sound, we need to re-insert the memory and wipe the gold finger with a soft cloth.

3. It may also be that the BIOS chip is oxidized or released badly, or because of the environment, the pins of the chip are released due to oxidation.

4.If you turn it on, the fan will restart after a while, the motherboard battery will be deducted, and you can discharge it with metal.

Of course, reinstalling the system can solve 99% of the problems, but it can't deal with the ability to reinstall the system.

Not easy to look at.

The computer cannot start normally after changing the new network card The computer cannot start normally after changing the new network card, because the network card driver does not match. 1. First of all, you must determine the model of this computer, and whether the system is 32-bit or 64-bit. 2. You can first use the computer to open the official website of the notebook, find the service and support, and then find the corresponding network card driver, and then ** to this computer.

3. Extract the file and click on the steup. Run and install. 4. Then restart the computer to access the Internet.
