About six months ago I build my first system and it's worked fine except for a buzzing in my headphones. I haven't bothered to do anything about it because it's quiet enough that I don't hear it if I have music on or anything, but it's an odd problem and I would like to fix it.
I'm pretty sure it is CPU feedback causing it because it occurs every time I move my mouse but this seems to only happen on old mobos and I'm using the b450 Aorus m.
When I was building my system I struggled to get the motherboard holes lined up with the case standoffs so I tore off the squishy foil part on the back of the IO shield which I wasn't sure was supposed to be there or not. In hindsight that was probably pretty dumb but could that be causing the problem or is it a faulty mobo? The buzzing is in both the front and rear audio jacks and I don't have USB headphones to test if it happens through USB.
If that is the problem is there any reason I shouldn't just remove the IO shield?
