If the motherboard is broken, will the power supply fan turn?

Will turn. Will definitely turn. As long as the power supply is not broken.

Because the button you turn on is the cable that connects the motherboard to the power supply. You press the power button. The tentacles on the motherboard are connected to the activation switch of the power supply.

The power supply then outputs the signal to the motherboard. The first one is the DC12V interface of the fan. So if the motherboard is broken, the fan will definitely turn.

As long as the power supply and fan are not broken, they will definitely turn. How to test if the fan is broken? You unplug the fan's socket.

Be sure to unplug it. Otherwise, the motherboard will really be burned. with two wires.

Insert the red and black wires of the fan's cable connector, respectively. Then use your phone's battery as a test power source. Red + pole.

Black wire connection-pole. If the fan turns. It's not bad.

Then it's time to consider that it's your power supply. Sometimes the power supply is broken. We usually think that there is a problem with the motherboard.

In fact, the power supply is really bad fast hardware.

If the motherboard is broken, it is also possible for the power supply fan to turn, after all, there are many bad situations, and the power supply will not turn only when the motherboard is not powered on.

If the motherboard is broken, the power supply fan may not rotate, and it is impossible to judge whether the motherboard is good by whether the power supply fan is running.

As long as the motherboard boot circuit part can work, after pressing the computer power button, by shorting the power signal cable, the power supply starts to work and the fan can turn, but this does not mean that the motherboard is good, and other problems will still cause the computer to fail to boot or the motherboard is used abnormally.

Hello: 1, the motherboard is broken, the power supply [It is possible for the fan to turn or notIt depends on where the damage is and how much damage it is.

2. MotherboardDamaged placesThe impact on the power supply is also different

a. Short-circuit fault of power supply line, or other faults, will cause power protection, but will not affect the rotation of the fan.

b. If the starting circuit of the computer motherboard fails, or the power fuse is disconnected caused by a large short circuit, the fan will not rotate.

If the power supply line is broken, there is no circuit in the power supply, then the power supply fan will not turn, if the power supply line is fine, but it is faulty in other places, the power supply fan will still turn after starting, but the computer function will be affected.

1. It can only be said that it maybe, depending on what circuit of the motherboard is bad and what is the severity of the bad, 2. The entire motherboard of the short-circuit cannot be powered on, the power supply cannot be started, and the fan will not turn

It depends on that part of the motherboard that is broken.

The motherboard is composed of hundreds of components, and if different components are broken, the faults will be different, and it is difficult to say whether it will affect the fan.

When you ask this, it's like, "When a person is sick, will he be blind?" "A truth.

1. Will turn. Will definitely turn. As long as the power supply is not broken, because the button you turn on is the cable that connects the motherboard to the power supply.

As soon as you press the power button, the antennae on the motherboard will be connected to the activation switch of the power supply, and the power supply will output a signal to the motherboard, and the first one is the DC12V interface of the fan.

Heng Belt Pei 2, so the motherboard is broken, and the fan will definitely turn. As long as the power supply and fan are not broken, it will definitely turn, how to test if the fan is broken, you unplug the fan. Be sure to unplug it, otherwise it will really burn the motherboard.

with two wires. Insert the red line and black wire of the fan wire interface respectively, and then use your mobile phone battery as the only test power, 3. Red + extreme black wire to the pole, if the fan turns. It's not broken, then you have to consider that it's your power supply problem, sometimes the power supply is broken, we usually think that there is a problem with the motherboard, but in fact, the power supply is really bad and fast hardware.

Summary. What about the display? It's still not responding.,Don't say it, I'll default to your monitor not responding.。

First of all, your keyboard is not lit, the system is not installed or the boot is lost, the monitor does not know whether it is bright or not, and the lack of light is most likely a problem with the graphics card, or you try to wipe the gold finger and connection cable of the interface.

It is also possible that the memory is turned but you said that the fan turned, if the memory is broken, the fan will stop after a while, and it should not be the memory.

If the motherboard is broken, can the CPU fan be rotated?

There are many kinds of broken motherboards, and if the power supply line is not broken, the fan can still rotate normally. The next time you ask a question, just say the question, you have another question, ask the fan what to do.

What happens if it doesn't start? What the display outputs.

After the fan is turned, the keyboard light is not on, can I control the case and the keypad?

The keyboard light does not light up, and the host computer cannot start.

What about the display? It's still not responding.,Don't say it, I'll default to your monitor not responding.。 First of all, your keyboard is not lit, the system is not installed or the boot is lost, the monitor does not know whether it is bright or not, and the lack of light is most likely a problem with the graphics card, or you try to wipe the gold finger and connection cable of the interface.

It is also possible that the memory is turned but you said that the fan turned, if the memory is broken, the fan will stop after a while, and it should not be the memory.

The monitor didn't respond.

The main problem is that the console won't boot and the monitor won't light up.

It's not like that, the host boot that ordinary people refer to is just entering the system. But in fact, it's just called the entry boot, and there are many operations before that. Even if you don't have a hard disk display, it can be lit.

If it doesn't light up, it's probably a problem with the graphics card, or you try wiping the gold finger of the interface and changing the cable.

The monitor will light up, but when it turns on, the screen will turn off, and the host unit will not turn on.

The platform does not allow private contact, I have sent the processing plan, I have already sent the solution above, will you operate and not give me feedback? If you don't know where the graphics card is, I can tell you, I can't help it if you don't give me feedback all the time.

If it doesn't light up, it's probably a problem with the graphics card, or you wipe the gold finger of the interface and change the cable.

It depends on the situation, if the motherboard burns along with the graphics card, it will definitely not be rotated, and if there is a problem with the graphics card socket of the motherboard, the graphics card fan will not turn, but this does not mean that the graphics card is broken.

It depends on what kind of bad it is.

Some of the bad ones may also power the graphics card.

If the graphics card slot part is broken, it will not be powered and will not turn.

If the control fan is not broken, it will rotate, depending on the degree of damage to the motherboard.

If the wiring responsible for supplying power to the fan is okay, the fan will still turn.

1. First of all, we conduct a comprehensive check on the connection between the computer monitor and the host, and plug each connection back to see if there is a connection problem.

2. If the fault still exists, then we need to open the chassis to see if the chassis contains metals and other substances, causing a short circuit in the computer host circuit, and then we smell the computer to see if there is a burning smell, and see if there are damaged components around the motherboard and around the CPU.

3. After checking the whole chassis, there is no abnormality in the chassis, then we will dust the chassis.

4. If it can't be turned on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

5. If the fault still exists, it is likely to be the fault of the memory card, graphics card, CPU, motherboard, etc., at this time, we only need to plug and unplug these hardware, or replace it again, and try to find the cause one by one.

It should be that the power supply is broken, and the power supply is responsible for supplying power to the motherboard and CPU, is it the reason for the low voltage?
