1. If during use, there is only a buzzing sound when the host is noisy, it can be determined that most of this noise comes from the fan. Perhaps due to the prolonged use of the fan and the relatively dry interior, the fan in the host may produce buzzing noise, which is a normal phenomenon during the use of the computer. The correct solution is to disassemble the computer's main unit, prepare a brush, and then clean the small fan inside the main unit. Generally, the small fan is covered in dust, which affects the computer's heat dissipation and causes noise. During the cleaning process, the small fan should not come into contact with water. After cleaning the small fan, add some lubricating oil, and the noise of the main unit will disappear.
2. If the computer host produces clicking noise, one of the reasons may be that the power cord inside the host touches the CPU fan, or it is caused by the graphics card cooling fan. When encountering this noise, we can first turn off the computer, then turn on the host, and check if there are any wires touching the part of the fan. If the wires are messy, we can reorganize the wires and then turn on the computer, Basically, this kind of noise can also be solved.
3. In addition to the two types of noise mentioned above, there is also a common type of noise that comes from the computer hard drive. It is usually caused by internal damage to the hard drive, and if you try to touch the computer hard drive with your hand and feel a vibration, then this type of noise is caused by damage to the computer hard drive. In this case, we need to first backup the data in the computer, Then replace the computer hard drive in a timely manner to solve the problem of noise generation.
4. The power supply of a computer is also one of the sources of noise, which is usually caused by the cooling fan of the power supply and the internal circuit of the computer host. During the inspection process, we can observe the approximate location of the noise based on the sound. If it is a problem with the power supply, you can go to a professional repair center for warranty. If the warranty period has expired, you can try to clean the dust around the computer first, Alternatively, it is possible to replace the power supply.
