Buzzing noise when selecting text/moving heavy processes' window

[Vitality]

Few months ago I built a new PC because it's better than trying to upgrade my older one. So I decided to buy everything new except SSD and PSU.

Here is the list of what I currently have:
Motherboard: MSI Z490 Unify
Ram: TEAMGROUP T-Force Xtreem Samsung IC 16GB Kit (2x8GB) 4133MHz (PC4-33000) CL18
CPU: I7 10700K
SSD: Samsung Evo 860
Cooler: Noctua nh-d15
GPU: EVGA GeForce RTX 2070 SUPER FTW3 ULTRA GAMING, 08G-P4-3277-KR
PSU: Seasonic Tx-700

When using programs that are taxing such as Visual Studio or any heavy program, I can hear a buzzing noise coming out of the motherboard (NOT from my headphones) when selecting program code with my mouse. I also can hear the noise when moving Visual Studio window. The noise seem to stop whenever i stop dragging that window.

I already swapped the motherboard from an Asrock motherboard because I thought it was the problem. The PSU was also swapped from an evga one because i thought the connectors were poor.

Therefore, the things i suspect are:
-it's either a bios option that's in newer motherboards
-Bad CPU (Since CPU controls IO)
-Bad GPU (the RTX 2070 is known to have a buzzing noise in general. However, I don't think it's 100% the issue here, because it seem to depend on mouse input, which is IO side)
-Bad Ram (unlikely because it comes out normal after testing)

People who had the same issue, which component turned out to be the cause?

That sounds like a coil whine, and usually comes from the GPU.
Me personally don't like it but from what I've read online doesn't necessary means that anything is wrong, especially if you are not experiencing any issues.
The SMPS use frequency above the hearing range but sometimes the coils can oscillate below that frequency and we can hear it.

Yep does that. I'll tell you another one. In case you accidentally spill water in the power socket, that causes another kind of noise, too.

This kind of noise can come from rapid changes in system load (which are caused by dragging the window or other actions) which cause changes in electrical current draw. That current passes through inductors (coils) which can make a buzzing or whine noise under certain conditions.

I think one of my old athlon xp 2500+ systems did something like this.

This kind of noise probably does not indicate a fault in any of the components.

They way I would fix this is by replacing the mainboard or PSU. But since you already did that... I guess you can try taking the GPU out and using your CPUs integrated GPU to see if that changes anything.

In the BIOS there are settings called "spread spectrum". These are meant to stop EMI. This is just a wild guess but you can try toggling them to see if it changes anything.

sometimes power supplies do this as well :
you can try to use something like this to specify where it comes from- no joke:

no joke:

Nope - it is no joke. This method is often recommended. Use the inner tube from a paper towel or aluminum foil roll like a stethoscope to see (hear) if you can pinpoint the source of the sound. Toilet paper roll tubes are too short. Gift wrap tubes work great as you can stand further away which can help with isolation - and you can cut them to a size that works best for you.

I have an old canister vacuum hose I use. I really like that because it is so flexible, you can manipulate it in just about any way without it crimping or folding on itself. And you can fit the end with a reduction nozzle to focus in even closer.

Hey, I have nearly the same setup with you. I had a 650 watt PSU and there was no noise at all. Now I use 850 watt PSU with the same setup and ther eit is the buzzing from somewhere near to the CPU. Have you found any bios settings to solve it or have you solved the problem some how ?
