What to do if the electric fan on the CPU keeps turning

There is no other way but to change the power supply, believe it or not!

You can press and hold the power on button for about 30 seconds, which can power off the main unit.

No need to pull the plug. Try it, it works.

Go and change the power supply, if you can't change the motherboard, if it doesn't work, you will change it all!

If you have a problem with your power settings, you can fix it by redesigning the power supply in the window!!

If you have a problem with the motherboard, you can see if you can fix it.

The most straightforward way: pull the plug!

You can try to check the motherboard.

1.Turn off the power on the board.

2.Maintenance.

To be precise, it's not your power supply problem, it's your motherboard's service circuit that is faulty, and I suggest you take it to the repair department to check it.

If it's not a motherboard issue. There is no other way than to change the power supply...

It's super simple, unplug the power and solve everything, and it will definitely not turn again!

First of all, confirm your question, has this been the case before? Or has it just recently appeared?

If this problem persists, it is recommended to check whether the jumper on the motherboard is plugged in correctly.

If it's recent, what did you do with the computer before it appeared? It may be that there is a problem with the power supply, and you can try to test it with a different power supply.

1. The power supply is faulty or the power supply voltage is insufficient.

2. The switch or rerest key on the host does not pop up after pressing it.

3. The CPU and CPU socket are not fully contacted.

4. The power supply circuit of the motherboard is faulty.

There are two possibilities as you say:

1. The fan stops after a turn, and it doesn't stop and stop repeatedly, 80% of it is a switch problem.

2. The fan stopped after a turn. Repeatedly stop and stop, it must be 3, the CPU and the base are not in good contact.

3. The most likely thing is that the CPU fan is broken or the fan is oiled and needs to be replaced.

1. If you say that you can't enter the operating system means that the screen does not display a black screen, this must be a hardware failure, and the time and time may be caused by the motherboard problem and the continuous restart, or other problems. It needs to be repaired.

2. If your screen is displayed normally, but the system cannot start normally, first ignore the problem of fan rotation for the time being, and reinstall the system first, if the same is the hardware failure, the system may not be able to start the system may be caused by a hard disk failure or a motherboard failure.

3. If your system can start the system after reinstallation, the next Master Lu will look at the temperature of the graphics card and CPU, the CPU fan is adjusted according to the temperature, if there is a problem with heat dissipation, clean the fan shaft and replace the fan if it doesn't work, and the fan problem of the power supply also needs to be disassembled and cleaned up and refueled, and if it doesn't work, change the fan.

There are many reasons why CPU fans can turn and stop from time to time, mainly in the following aspects.

1. The CPU temperature is low or the computer is in a dormant state, and the PU fan rotates and stops when it is normal.

The CPU works normally, according to the computer cup control, the computer CPU fan turns and stops, for example, the CPU temperature is relatively low, and the computer is in a sleep state.

2. Caused by CPU fan problems. For example, the resistance of the CPU fan is relatively large.

Solution: Clean the CPU fan, add lubricating oil to the CPU fan, and replace the CPU fan if it is damaged.

3. Caused by CPU fan power supply problems. For example, it is caused by insufficient voltage to the CPU fan.

Solution: There may be a problem with the computer power supply, repair the computer power supply.

4. Caused by computer motherboard problems.

Solution: Repair the computer motherboard.

5. Other hardware failures of the computer.

Solution: After-sales inspection and repair, replacement of damaged computer parts.

Expand your knowledge: The computer CPU fan turns and stops for a while, which can be roughly divided into two situations;

1. The fan is running normally.

First of all, if there is no problem with the heat dissipation of the computer, it is normal for the computer's CPU fan to rotate and stop for a while, and then repeat the cycle. Because the CPU fan is mainly used to take away the heat generated by the CPU, if the running program is small and the running program is less, the CPU occupies very little, so that the heat generated is very small, and if the heat can be dissipated normally, the CPU fan does not rotate. The CPU fan will only spin at a high speed when running multiple programs or large programs, and it will continue to rotate to remove heat and ensure that the computer works properly.

2. The fan stops abnormally and intermittently.

If this is the case, it is recommended that a Master Lu monitor the CPU and fan speed, if the CPU temperature is very high and the fan does not rotate, it is recommended to contact the after-sales service and ask a professional to check.

Let's change to a better one, after all, it's the heart of the computer It's a pity if it burns.
