Squeaky sound from computer

Since December 29 I hear an unpleasant electronic squeaky noise from the computer, it is audible up to about a meter from it (from the back of the computer), the computer is behind the second monitor and its back is facing me.

The sound is not the same whole time, sometimes it is louder, sometimes quieter. This morning(live in Poland) I went into the bios to see if it is there as well, and so it is, and it was the loudest so far. But after about 40-60 minutes it quieted a little, the same in the evening - it was turned off at 3 p.m. and turned on at 7 p.m., it squealed a lot and later slighty quieted.

I tried to locate the place of the sound (the fans make it difficult) and it is audible near the graphics and the power supply. I'm pretty sure it's not a whining coil from gpu (I used to play Portal 2 and when loading between locations the fps was above a thousand and the coil started squeaking) - the current sound is not that bad, I would say it is more electronic and kind of slightly vibrant. The load on the computer does not affect the squeaking in any way, the fans even drown it out. The fan-off mode in the graphics also does not affect the squeak in any way. Therefore, in the end, I would guess that it is something in the power supply.

Below I am sending a sound sample from the power supply.

I do not have any spare power supply or graphics card to replace, so I have 2 options:
1) take the computer to a computer repair shop to confirm where these sounds come from,
2) send the power supply for warranty.

Anyone ever had a problem like this? Or knows what it might be?

Have you cleaned your PC lately or ever, that is, have you blown out the dust that may accumulate inside the case?

From what you describe I'm wondering if the PSU fan has a bad bearing or perhaps has dust around the hub. The squeek could be any of the fans' hubs as they should be the only moving parts in your case.

So I turned off all 4 case fans and CPU fan for few seconds, and I'm 99% sure it is coming from PSU, specifically from the fan. I also found, using long cardboard tube, different sound - quiet chirping sound inside PSU.

I'm also wondering why the sound was sometimes loud, sometimes quiet, sometime almost unhearable.
