Interference with headset causing mic buzzing

[AntonChigurh]

So I recently purchased an Archer T5E wifi card for my pc. However, after installing the card, one of my friends remarked they were able to hear a buzzing noise whenever I talked on Discord. I'm 99% sure this is caused by some sort of interference from the wifi card, as I did not have this issue until I installed the card. I've been pulling my hair out trying to find ways to fix this, but nothing I've tried has seemed to work. If any of you audio wizards could help I'd be very grateful.

 

BTW I have a pair of HyperX Cloud II headphones, if that helps any.

Using the USB dongle? If not try that. And vice versa.

USB dongle for my headphones or the wifi card? Cause I am using the USB dongle for my headphones but my wifi card is PCIE

Okay so I've tried a couple different things. I thought potentially the cause of the buzz was a ground loop, so I switched my PC's wall outlet. No dice there. However, I noticed when I touch my PC case the humming goes away. No clue why that fixed it, but I obviously cant touch my pc case 24/7. I tried changing the USB port my mic is plugged into, which didn't help at all. I'm so confused here. Honestly I might just break down and buy some new headphones.
