What s going on with the CPU fan turning and stopping

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. An electric fan. Monitor the CPU as well as the fan speed if the CPU temperature.

If it is very high and the fan does not turn, it is recommended to contact the after-sales service and ask a professional to check it.

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.

Start the computer and find that the computer can't turn on, the monitor doesn't respond, and in less than 10 seconds, the computer stops running, unplug the power cord and open the case, and then press the computer switch button with the power cord in your hand, and see with your eyes that the CPU fan turns and stops, and the computer can't start and can't turn on. So do you know what to do if the computer CPU fan turns and stops? Here are some relevant information I have compiled about the computer CPU fan turning and stopping for your reference.

The solution to turn the computer CPU fan and stop itIf there is a problem with the power supply or the motherboard BIOS settings, first turn on the motherboard battery.

Go down and put it back in after a few minutes.

As you can see in the image below, you will understand.

The new motherboard battery is not expensive, only less than five yuan, and the way to change it is very simple, turn off the computer with a Phillips screwdriver.

When opening the computer case, be careful to touch the computer hardware.

Be sure to touch the metal with your hands before to prevent static electricity from harming the hardware. with"hands"Buckle it down and put on a new one! This is shown in the figure below.

After the motherboard battery is replaced, you enter the BIOS system to set the time, you press F1 to enter, you can use the arrow keys to move the cursor to select the setting options, then press Enter to enter the submenu, use the ESC key to return to the parent menu, use the Page Up and Page Down keys to select specific options, the F10 key to keep and exit the BIOS settings, some machines are not saved by pressing F10, you can press the FN key combination to save.

If you suspect that there is a problem with the power supply, unplug the original power supply and plug it in again, boot the test to see if the fault has been solved, if not, you can only replace it with a new power supply or a good old power supply, and you can solve this fault. I just solved the problem that the computer can't turn on and the CPU fan turns and stops through the second method.

Note: There are many reasons for computer malfunction, and not every method is effective, just a reference. The above two methods hope to help users, it is best to ask a professional to check and troubleshoot!

1.The CPU fan stops as soon as it turns.

2.The computer can't turn on normally, and the fan stops when it turns around.

3.The computer doesn't start, and the fan stops when it turns.

4.The motherboard CPU fan turns and stops.

5.What to do if the computer CPU fan won't turn.

6.How to adjust the speed of the CPU fan.

1. In this case, the power supply is broken somewhere, so that the power supply load power is reduced, and the host can not be started normally, and the power supply should be replaced with the same power as the bad power supply, which should be about 100 yuan.

2. The CPU is the brain of the computer, so the power supply, it is not only one of the important accessories of the computer, but also the heart of the computer. The computer power supply fan is the function of cooling the heart, and the computer power supply fan does not work, which directly affects the stability of the computer power supply.

Summary. Close the small white blocks at both ends of the desktop memory slot inward to the close buckle first, but do not make a snapping sound. Smoothly plug in the memory module to make the memory module tight.

If it still can't be installed, pay attention to whether the memory module is installed in the opposite direction. If the direction is correct, close the small white pieces (buckles) on both sides a little more. Wait until the memory module is almost plugged in, and then buckle the small white blocks at both ends.

You will hear a Kata, and the memory module will be installed. Don't make a miracle out of memory module installation, and dial the small white block reasonably. Pay attention to whether the socket type corresponds to the memory (DDR5 and DDR4 are different).

Won't turn on. Kiss. <>

Hello, glad to answer your <>

Hello, the computer CPU fan stops when it turns once, and then turns again, this situation is that the memory module is not plugged in tightly.

The black screen can't be turned on, and when you press the power supply, it will keep restarting, and the CPU fan will only turn for a few seconds. This state is that the memory module does not read the bar. It's not plugged in tightly or there is a problem with the slot. You plug it back in and try it.

When installing the memory module, look at the card slot, and you must hear a click at both ends to snap into the position. If you're a newer motherboard, you're bound to have a clicking sound. If you don't hear it during installation, you didn't plug it in tightly.

Close the small white blocks at both ends of the desktop memory slot inward to the close buckle first, but do not make a snapping sound. Smoothly plug in the memory module to make the memory module tight. If it still can't be installed, pay attention to whether the memory module is installed in the opposite direction.

If the direction is correct, close the small white pieces (buckles) on both sides a little more. Wait until the memory module is almost plugged in, and then buckle the small white blocks at both ends. You will hear a Kata, and the memory module will be installed.

Don't make a miracle out of memory module installation, and dial the small white block reasonably. Pay attention to whether the socket type corresponds to the memory (DDR5 and DDR4 are different).
