Anonymous users2024-02-13The sound emitted by the power supply part is generally a relatively low "buzzing" sound. If it's a continuous "chainsaw" sound that rings for a while when you first turn it on, it's probably a fan problem. Solution (1) Brush the ash and oil; (2) Replace it with a new one.
If you are not afraid of trouble, the former is both economical and practical. You can use a small brush or a large oil brush to blow while brushing (it is best to have a "leather tiger" for blowing soot, or you can use a hair dryer to hit the cold air gear, or even use a pump to install a "gas needle" for playing basketball); To apply oil, uncover the circular covering film in the middle of the fan, let the shaft be exposed, drip a little high-grade lubricating oil (do not use cooking oil, because the cooking oil will be sticky for a long time, affecting the operation of the fan), and then cover the film. Sometimes not all of them are ringing, how can you tell which fan is ringing?
You can take a chopstick, turn on the case to turn on the power, put one end of the chopsticks on the board with a fan, and the other end on the face, feel the vibration, and the vibration disappears with the "roar". After brushing and oiling, the problem could not be solved, so it had to be replaced with a new one.

Generally, the fan of the machine will spin wildly for a while when it is turned on.
It's also possible that your case enclosure is not of good quality.
Can't stand the crazy rotation of the fan.
You can check which fan is having the problem.
Computer consumables are sold in the market.
Just put it on.

Anonymous users2024-02-10Can you change the power supply and see if it still rings ?
The computer is not very fragile, and if you unplug the power supply and dust it for him, I think it shouldn't be a big deal!

Anonymous users2024-02-08Normal brand machines are like this.
It is best to meet politely, raise this kind of problem face to face, and tell them euphemistically: because the parents do not sleep well, because this inadvertent sound affects the rest of the parents, and they are worried that the body will not be able to bear it, and there will be problems. Anyone who is kind will be moved by your parents' physical behavior, so be careful in the future. It's much better than the way to write a note and stick it to someone's door.
According to the "Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution". >>>More
This sound is the sound of the fan, when it is just started, the lubricating oil in the fan is not completely melted, and it will produce noise, and when the operation is stable, it will be fine.
You can take appropriate measures to protect your rights
According to the provisions of China's "Noise Pollution Prevention and Control Law", the problem of domestic noise disturbance shall be handled by the public security organs. Noise from daily life includes: noise from entertainment activities, loudspeakers, ceremonial celebrations, car alarms, pet barking, loud hawking, etc. >>>More
The noise of the computer depends on what characteristics there are. A slight whirring sound is the "wind sound" when the fan is working, which is normal. If it is an intermittent "click" sound (the sound is also soft), it may be the sound of the hard disk reading, and you can't do anything about it, except for the backup of important files, you can ignore it. >>>More
