So, a few weeks ago I built a gaming PC using all new parts, but all of a sudden I am hearing a crackling sound coming from the back. It's loudest on startup, but never seems to go away and is driving me crazy. I've never noticed it before, but when I was installing a game, it became incredibly loud and worrying. Any ideas? Because I don't think it's ever done this before.
