Analysis of the problem of loud computer startup sound

I believe many people don’t like to start loudly, but many people do encounter such a problem, so what should we do? How to solve this problem? Why is this so? Today, let’s take a look at why your computer makes loud noises when it starts up.

Why does the computer sound loud when it is turned on?

First of all, we analyzed the problem of loud startup sound:

1. It is estimated to be caused by the CPU or power supply fan. It is likely that the fan has too much dust or the fan is broken.

2. After observation and research, we found that the sound of the fan was loud for about 8 seconds just after pressing the start button, and then became quieter.

When did you buy your computer? Is this a used machine? Or bought it new? Under normal circumstances, there will be sound when the computer is turned on. Let's check if there is a problem with the power supply? Some power supplies are loud, like tractors!

4. When starting up, almost all fans are at full load. Although the sound is loud, it will basically become quieter after waiting for about 8 seconds. If the sound persists, your fan has too much dust or the fan is old. We can perform a series of maintenance steps, including cleaning dust, adding lubricant, and checking whether the sound is caused by the hard disk or fan

5. Open the main case and listen to see where the sound is. If it is the sound coming from the graphics card or CPU fan, we can add a little more oil. If it doesn't work, we can replace it!
