So I found out its possible to use a 2nd gpu for encoding on OBS (no SLI or crossfire) and had a spare gtx 550ti laying around and decided to try it out. I plug in everyithing, turn on my pc and 1st thing I notice after it booted is a static-beeping type of noise both in the back and front 3.5mm jack and the noise makes different tones depending on what apps are running and what jack i plug it into. Anyone have any ideas besides me somehow damaging the motherboard?
