Weird Microphone Buzzing/Static Noise

[Kryzys]

Hey, folks.

I know this had been an issue posted everywhere on the internet, this is my first time having an issue like this since the very old speakers days. Mind you, I've had this PC for a long while before this issue started, so this isn't an old problem.
Basically, my microphone all of a sudden started to produce electricity static noises in the background which makes the whole experience tanked, it's not my headset, it's not my hardware, and the static is gone as soon as I put my hand on the case and the feet on the floor, so what could it be?
I've theorized three possible reasons:

1. Motherboard I/O shield doing something bad.
2. My PC is not grounded properly.
3. My port jack is malfunctioning.

I've searched for the solution everywhere on the internet, I've tested my microphone on a mobile device, on my sister laptop, they all worked fine except for my desktop PC. 
I have a B550M Pro VDH and A650GL, and they are relatively new, not worn, not overused.

Now I'm asking if any of you at all who had this problem before and KNOWS how to fix to find a solution for my problem.

Possibility 1. Sounds like the microphone traces might be going bad on the pc.

Possibility 2. The port might be dirty. 

Possibility 3. Outdated Drivers. 

What type of headset is this, and what connection is this: 3.5MM, Bluetooth, or XLR?

I would check for foreign material in the ports and corrosion.

Thanks for your input. 
I have Razer Blackshark, connection is via 3.5mm jack.
The first possibility is likely but the other two are not the case.
How to check for microphone traces and diagnose it, and how do I check for 'foreign material'?

To check the traces, you would need the original electrical diagram from the manufacturer. To check for foreign material, you would use a bright light to shine into the hole, or use a small, pick-like device that's not sharp. Also, check the jack for corrosion. Here's a YouTube video.

Thanks, man! But I really really doubt it's the case of wearing... my motherboard (B550M) is pretty new like around 8 months of use. This is something simple to solve but hard to pinpoint
