What's with the noise on the computer? Computer noise causes and solutions
As a necessary product for our life and work, computers are used for a long time, and it is inevitable that there will be some small problems. Some computers will suddenly make a lot of noise, affecting our mood, it is really very annoying.
In order to solve the noise problem, we have to "right medicine" to find the cause of the noise, the following Xiaobian will introduce the causes and solutions of computer noise, come and see!
1. Abnormal rotation of computer fans and excessive dust accumulation
The biggest source of noise in computers is fans, such as computer fans, CPU fans, graphics card fans, and case fans. Because of the frequent exchange of external air, in the environment of dry air and too much dust, often because of the lack of oil, dust caused by rotation, emit "buzzing" noise, at this time we need to clean the dust of the fan and the entire computer, and add lubricating oil to the fan, if the problem is still please replace the fan.
2. Plug and power cord are in poor contact
Sometimes the computer will make a "sizzle" sound, which is not loud but annoying. In fact, this is mostly due to poor quality or mismatched plugs and power cords that cause poor contact, resulting in noise. Therefore, when purchasing or assembling a computer, be sure to choose a regular plug and power cord, in addition to avoiding noise, but also to ensure safety.
Three, screw loose
Brand computer: Because the chassis and hard disk, optical drive, fan, etc., are mostly fixed by the buckle, there is rarely noise for this reason.
Assembling computers: The use of screws is more, such as case cover, power supply, hard disk, optical drive, motherboard, fan, etc., to use screws. If the screw is not tight during installation or there is a tremor in the later use process, it is easier to cause noise. The more common ones are the noise caused by the loosening of the chassis cover screws and power supply fixing screws.
Four, motherboard, chassis deformation
In the assembly of the computer, do not figure cheap, think that the chassis is not as important as the CPU, graphics card, the use of inferior, in fact, the inferior chassis is easy to deformation in the process of use; Motherboard is the same, the quality of the motherboard is difficult to bear the weight of the CPU, the fan, will also occur deformation, once the motherboard or chassis deformation, in the chassis fan or hard disk rotation, it is easy to produce noise.
Capacitor, inductor welding or damage
Sometimes you will hear a slight noise from the motherboard, at this time, it is 80% because a capacitor or inductor on the motherboard occurs virtual welding or damage. You need to disassemble the computer and examine the motherboard carefully. For example, some electrolytic capacitors, or bulge, or leakage problems, you can see with the naked eye, but if it is the inductance coil, you have to work a little.
Matters needing attention
Prevent static electricity. Static electricity is easy to damage the integrated circuit, so before opening the chassis, it is best to touch the grounding conductor with your hand or wash your hands to release the static electricity that may be carried on your body. If conditions are available, you can wear static electricity rings to effectively avoid static electricity problems.
The above is the reason for the computer noise and the solution, not friends can refer to this article, I hope to help you!
