Static sound from pc

[Kimbou1]

Hi all

 

My pc is making a high pitch noise, almost like a static sound. Its really hard to tell where it comes from, but when i put my ear on the cpu backplate i can hear it really good. 

 

The sound isnt "stable", it goes up and down, and when i move the mouse the sound follow the movement, and when i start a game it gets even worse. 

 

But when im in bios its gone. 

 

So far i've tested with :

 

- New psu

- New gpu

- 2 different cpu coolers

- New motherboard

 

The pc :

 

I5 10600k

Tuf 3060ti

Asus tuf z490

16 gb ram 3200mhz

Corsair rmx 650w

 

The sound is driving me crazy, and i dont know what more to test. 

 

Could it be drivers? Coilwhine?

 

I can also hear a rattling noise from the power adapter for my asus monitor, is that normal? 

 

Would really appriciate some tips!
