Question Mic buzzing sounds (grounding issues?)

[Laponac]

I just moved into new apartment, setting up my and my gf's PC, everything works just fine

Until I started using my mic, it's Razer Seiren X. There is constant buzzing coming from it. I tried many things to fix it, turn volume of it down, switch USB ports, switching to dedicated audio USB port on my MOBO and no luck, when I put my hand on PC case buzzing gets bit lower, so that's why I am %100 sure its grounding issue. I even tried 2 different outlets and different cables to plug in whole PC, still same, tried mic on GFs PC, still same, same buzzing.

I am no expert in electricity so not sure if just whole power management in new apartment is bad and there is bad grounding or something, so I am trying to figure out what my options are to get this fixed as I am certain it's not up to just my pc since I tested it on my GF's PC as well.

Grounding issues that crop up after moving into a new abode is not the computer's fault, it's the issue with your wall outlet and quite probably the entire abode's wiring. Call in a certified electrician and have them scope out your wall outlet at the very least and the wiring in your abode.
