I d like to ask what I should do if my computer turns on very loudly

It must be that the fan is running out of oil.

Open the case and listen to the ** ring.

Then after shutting down, remove the fan (if the power supply is in it, take the power supply apart), there is a sticker on the back of the fan, take it off, there is a circle inside, pick it off with something, push out the fan spindle, wipe it clean, and then put on some solid grease, and that's it.

The solid-state ones take longer.

It should be the sound caused by the rotation of the power supply fan, the cup and the graphics card fan.

Isn't it a buzz? In general, it is caused by the lack of oil in the long-term operation of the power supply fan, CPU fan, etc., you can refuel or change the fan. I changed all the fans in the case a while ago, and now the sound is very low.

What is the ringing place?

If it's a CPU, there's no problem, which means that your heat dissipation is particularly good.

Power supply fan. CPU fan.

Add some oil or replace it.

Press the fan one by one with your hand, see which one is noisy, it's basically a CPU, it's good to change a good one, TT fan is good, and it's also a good choice to go to the 2-hand market.

Because your fan is not of good quality.

It's definitely a fan issue, most likely a graphics card fan or a power supply fan.

How it sounds, please describe it specifically.

Open the case and see where the sound is coming from, the fan or the motherboard? If it keeps ringing, it is probably a fan problem. The fan can be cleaned or replaced.

Upstairs is the right solution! It can be turned on but it keeps ringing, 80% of the reason is the fan!!

This is the problem of the fan: most of the fans now use grease, when the computer is just started, due to the low temperature, so the viscosity of the grease is large, the resistance is large, and the sound is louder, when it runs for a few minutes or shuts down and restarts, due to the rise in temperature, the viscosity of the grease decreases, the resistance becomes smaller, and the sound is smaller. If the sound has been loud, it means that the fan should be refueled, there is a piece of self-adhesive on the back of the fan, uncover it, use a toothpick to dip a drop of sewing machine oil into it (the size of a rice grain), and then dip the self-adhesive on the line If it does not work after refueling, it means that the fan should be replaced due to aging Password cracking data station Maintenance:

Turn on the power (be sure to cut off the power, the voltage is very high and dangerous) take out the fan Take off the sticker on the back of the fan carefully If there is a small hole in it, drop a little liquid lubricating oil into it (sewing machine oil, watch oil is better) But not too much so as not to turn the fan to get oil Finally, put a sticker OK If there is no oil hole on the back of the fan, then there must be a larger round soft rubber plug on the back of the fan Hook the plug out with a needle Put the fan rotor (the metal rod with the fan) Pull it out and clean it, then apply some solid lubricating oil to its smooth metal rod Then apply lubricating oil to the part where both ends of the stator (the part with the coil on it) are recessed Install the stator and turn it twice to make the lubricating oil even, and finally install the plug and stick the sticker OK Note: Take off the sticker and oil it, please make sure that the back of the fan is clean Otherwise, the sticker will not stick to it Oil it appropriately Don't put it too much P.S. Some fans (such as graphics cards) are magnetic levitation and cannot be lubricated for them This kind of fan sound is completely due to physical collision ( For example, the power cord of the fan is slightly in contact with the fan).

I guess it's the sound of a fan. If it's the sound of the fan and it's working properly, you don't have to worry about that.
