Buzzing noise coming from Mic

Didn't know where to post and what topic to pick so I'm going to try here...

as the title suggests I have been hearing intermittent buzzing noises coming from my Microphone as well as people that I'm communicating with...they tell me the noise is unbearable. I can hear it faintly but the people on the other end that I'm talking
with in skype or what ever voip I'm using are saying it gets extremely loud. Note that it's not a static sound it is a buzzing sound as if someone is getting electrocuted

I have tried many things to fix or correct the problems doing the following

-trying a different mic

-switching from usb to pins and vice versa

-trying different usb slots both front and back of case

-reformatting computer

-checking to see if motherboard is properly secure and grounded to tower

-grounding the case using a copper wire

-trying different outlets

-adjusting sound settings

I would like to note that I also used my microphone on my laptop and the noise was happening ONLY in my room where the desktop computer is located....I was not hearing the noise coming from my laptop in other rooms. This suggests that there might be something
wrong with my room that's discharging some sort of EM field. If this is the case do I need an electrician to check my room?

Any advice or help on this matter would be greatly appreciated

N95 buzzing noise

I also have that slight buzzing noise which is bearable and it doesnt affect my calls or anything like that

Though once in a while usually after the phone has been plugged into the computer and alot of file transfers and apps installed i get a much louder buzzing noise that kills the battery in like 2 hours the only way to kill the noise is to switch the phone off
and than on again anyone else have this problem
