I got a new pair of headphones today and after awhile I noticed a quiet buzzing noise when I move my mouse around or type on the keyboard, soon I heard the noise without any user input until I restarted my PC then it was just buzzing when using my mouse and keyboard.
I tested several headphones and heard no noise however these new ones are better than my old ones, I've also tested them on my brother's PC and heard no buzzing.
I'm using my onboard VIA HD Audio driver(up to date). I still hear the noise even if I disable all audio devices.
Motherboard is a Gigabyte M4A785TD-V EVO. Is this what's to blame?
Rig, although I can't help but think most of this wont help with this.
