I've got quite the confusing issue and I was wondering if anyone has hit this before and knows a solution....
A quick rundown of my setup:
6700K @ 4.7ghz
16GB Gskill 3200 DDR4
EVGA Hybrid 1080
Asrock Fatal1ty Z270 Gaming K6
EVGA 850 G3
So basically, my computer has constant "buzzing" noise coming from it, no matter the load. The buzzing doesn't vary in volume, it's just always there. I originally had a Gigabtye Z70 Ultra Gaming motherboard in there, but I actually swapped out for the Asrock as I am giving the Gigabyte board to a friend for a buid. I was hoping that the buzzing was just a leaking cap or something on the motherboard, but swapping made no difference. I originally had a 1070 in my system, but that went to my girlfriend when I got the 1080. The build with the 1070 buzzed too, but the buzzing with the 1080 seems to be increased. I actually RMA'd the first 1080 I got because of the buzzing, but the second one made no difference either. Next, I tried a different power supply, and no luck.
Now I just noticed something last night that really got me thinking. When I'm wearing headphones and the playing a game, if I move my head close to the PC, I hear buzzing in the headphones and it gets louder the closer that I get. The buzz sounds like "60hz hum" to me (not sure if that phrase is universal, but I play bass guitar, and 60hz hum is a problem that happens with active pickups sometimes in that regard). Thinking it might be a grounding issue, I have tried the PC in different outlets throughout my apartment, but that hasn't made a difference either.
At this point, the only thing I can possibly think of trying is to take my PC over to my parents' house or something and plug it in there to see if the buzzing happens there, in case it is a grounding issue with my apartments wiring.
Has anyone else faced an issue like this? Or any ideas on other things to try? The buzzing is only annoying if I'm in the room late at night with my headphones off and there is no other noise in the room. So, it's not the biggest deal, but I thought I'd see if anybody had some input.
