What is the reason why the fan stops when the computer is turned on?

This article to share with you is related to the computer boot fan to stop the reason is what the content. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Computer boot, fan turn to stop the solution: 1, pull out the memory stick, with a dry cloth or rubber wipe the memory gold finger part;2, BIOS settings to restore factory settings;3, to clean up dust on the computer;4, the computer host to the computer shop for testing.

The computer turns on and stops, and then turns again, and it keeps repeating that it can't turn on

Fault analysis:

The computer starts to turn and then stops. This is due to poor contact with computer hardware, motherboard or subsequent hardware short circuit, power failure, etc. The reasons for these problems are either bad environment, humidity, and long time failure to boot.

1, memory loose or gold finger oxidation

This is the most likely, and many users are solved in this way. First of all, we will remove the memory, remove is also very simple, press the memory slot on both sides of the buckle (there are unilateral buckle) can pull out the memory, we had better take out the memory using a dry cloth or rubber wipe the memory gold finger part, so as not to appear gold finger oxidation caused by the problem, the memory will be re-inserted into the memory slot, boot try. If not, you can try to replace the slot to insert the memory, and in the case of multiple memories, keep one memory first and test alternately. If not, users with discrete graphics cards can also try to plug and unplug the discrete graphics card again.

2. BIOS error

Motherboard BIOS error fault can also cause this problem, we can try to restore the BIOS settings to factory settings, we will remove the button battery on the motherboard, after a few minutes, and then install the button battery in place to restore the BIOS initial value. It is also very simple to remove the button battery, pull the buckle outward, the button battery can automatically pop out, you can directly remove it.

3, too much dust caused

Dust is the biggest killer of hardware. Cleaning dust for computers is a very necessary thing for us to maintain computers daily. Too much dust accumulates and increases the temperature of hardware, which will affect the life of hardware. Many times, hardware damage is caused by too much dust. We can clean the dust by using hairbrushes, high-powered hair dryers, and clean the dust away.

4. Motherboard and power failure

If the above method test still does not work, then it may be caused by power supply or motherboard failure, this situation for the general population, there is no suitable hardware to replace the test, only the computer host to the computer store for testing, let the store first replace a power supply try, rule out whether it is a power supply problem, if the power supply for the problem is still, finally replace the motherboard try. If the hardware can be found in the warranty range, if not, only pay for the replacement of hardware.
