Distress! The motherboard light is on, and nothing else happens!

It should be that the cable is not plugged in properly, and there is a logo on it, and it should be connected according to the logo, and it is easy to burn the motherboard.

Yes, there are too many problems, and the simplest keyboard and mouse can't be plugged in.

Check to see if the boot cable is connected correctly and whether the power socket is loose.

Changing the wrench will definitely have to go to the line.

You may have plugged in the wrong power supply.

Find someone who can plug it in to help you solve it.

I guess it's a power supply problem.,My computer was struck by lightning and the condition of your machine is the same.,The motherboard light is on.,There's no response when you boot up.,Change a power supply to turn it on.。

On the fourth floor, you mess around again, change the chassis, the motherboard will burn, you will be a match, the keyboard will appear, and the battery will also appear.

1.Check all over the computer installation to see if your patch cords, power supplies, and plugs on the motherboard, are plugged in and wrong

2.Check the hardware problem, generally the motherboard light is on to indicate that it has been powered on, check whether the power supply is operating normally, just look at the fan (if the fan is slow, it means that the power supply is insufficient, not enough for the computer to start), check whether the electrolysis on the motherboard is flushed out.

3.It's just ruled out (try it with a new power supply).

In this case, the most common is that the power supply is broken, and the electrolysis on the motherboard will also flush out (that is, the top is bulging) when the weather is hot

Is there an alarm sound on the boot?

Check all the hardware at once

No problem, just plug it all in

Open again!

You can also try to change the BIOS battery on the motherboard, some old machines are out of power is this symptom.

It's also possible that the motherboard burned out.

Did you plug the switch into the wrong wire!! Double-check the inspection !!

Well, there are a lot of questions, it's hard to say.

But you can try to take the memory off and plug it in first.

Now there is no way to rule out that there is a problem in the end, because if it is a motherboard problem, this kind of failure should not be bought on October 1, and it should not be caused by a long time of booting. If the machine is not a quality issue, that is.

Is the power supply any good? I think it's a power supply problem, make sure the number of power pins is correct.

Hey,Mine is the same.,The old motherboard used to be lit up.,And then today I bought a new motherboard and it still doesn't light up.,The worst thing is that I'm short-circuited and the power supply is normal.,So the power supply should be good.,Memory and hard disk are no problem.,But I guess it's the processor is broken.,Anyway, it's not the processor that's broken or the power supply is broken.,I originally thought I could use it by buying a new motherboard.,I didn't expect it to be lit.,I'm going to take it to the computer store tomorrow to repair.,It's not that I'm bragging.,It's just that I don't have tools., If I still have a host, I can rule out which hardware is broken, in fact, many people in computer stores are very poor, like us, they will only replace the hardware and check that there is a problem, but he will not repair any hardware, because they will not repair.

Wipe the gold finger of the memory and plug it back in.

You can go to the computer city to test if there is any problem with the motherboard.

The first step is to turn off the host computer (with the power button or power cord plug of the host), open the main chassis, and then turn on the host to see if the power fan, CPU fan, and graphics card fan (if any) are rotating normally? Then observe whether the power indicator and hard disk indicator on the host are on? Are the keyboard lights and mouse on?

See if the cord is plugged in.

Unplug the graphics card, plug in the core and try it, the screen is not bright, and the screen is no problem. Then wipe the gold finger of the graphics card and plug it back in to try again. (That's how I got it in the first place).

It is recommended to plug and unplug the memory, give it a try, if you press the on/off button, all the fans do not rotate, it is recommended to go to the computer company to test it, which can quickly and conveniently solve the problem.

There are the following reasons why the computer console does not light up:

The first reason: is that your button itself has a problem, so you will not respond as soon as you press it, this is the common switch button has poor contact, so you can sometimes turn it on, decisively replace the main unit button, or replace the button connection cable of the switch key and the restart button.

The second reason: which is the problem with the filter capacitor of your host power supply, when these two large capacitors burst or dew, causing problems with power supply, it will be like this press the power button, no response, but sometimes the power supply of this large capacitor meets the requirements, and it can be turned on, so you just need to replace the host power supply. The third reason:

It is the memory or graphics card gold finger is oxidized, resulting in poor contact between the memory and the memory slot, and the poor contact between the graphics card and the graphics card slot, resulting in hardware incompatibility, and the resulting black screen phenomenon.

Solution: You can turn off the power first, open the compartment, dial out the memory, use the eraser to wipe the part of the gold finger back and forth a few times, and then change a memory slot to insert it back, on the line, if there is a separate graphics card, you can also use the same method to deal with the graphics card, just don't change the slot.

If the memory module is not in good contact, unplug it and erase the gold finger with an eraser, blow the slot clean and plug it back in.

You can take your computer to a computer repair shop for a complete overhaul.

You try it minimally first, use a single memory, motherboard, power supply, add CPU, no need to heat dissipation, start the computer and try it first, if there is still a problem, ask me again.

The hardware stability is not good, since it can be turned on, there should be no compatibility problems.

There are two situations when we usually say that the computer does not light up, one is to press the power button, the computer case is not powered on, the fan does not rotate, and the other is that the case is running normally, but the monitor has no signal.

Newly assembled computers, boot does not turn on, generally there is a problem during installation, such as the jumper is not connected, the motherboard or CPU power supply is not connected, or the power supply behind the power supply is not turned on, saving a small probability of power failure or motherboard failure.

The latter has no signal when the display is powered on, and the situation is a bit complicated, and the following reasons are briefly summarized:

1. The memory is incompatible, it may be solved by replacing the memory slot interface or flashing the BIOS.

2. The power supply is unstable, perhaps because of transportation or product problems, resulting in problems with the power supply of the CPU and the motherboard.

3. The HDMI cable or DP cable connected to the display is connected to the motherboard, resulting in no signal, if you don't use the nuclear display, you should connect it to the interface of the graphics card.

Whether the hardware is aging, wiping the fan, eraser wiping the graphics card, or maybe your battery is unstable, it is possible to rule them out one by one. If it still doesn't work, you can only take it to the computer city for maintenance.

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

Dear ASUS users, Hello!

Based on your description, sorry, not sure about the exact model of your computer.

1. If your computer is an external battery, it is recommended to turn off the power adapter first, remove the battery, and then connect the power supply to try it after the computer is placed for half an hour.

2. After powering on, press FN+F7, FN+F8 to switch;

3. If the notebook has been installed with expanded memory, it is recommended that you take out the expanded memory and then boot it for testing.
