Okay so I recently built my first computer and I recently noticed that my psu was making a clicking noise. The computer works fine and I'm writing this right now with it. I'm not sure what the clicking noise means. It isn't like a buzzing noise it's just a very faint clicking. I doubt it is dust or anything like that since I've only had it for about a week. If I shut down my computer I still hear the clicking noise coming from the psu. What is this clicking noise?
