This problem started yesterday. I turned on my pc and on idle I could hear a loud click from my pc. I built it myself so I know it's not my fans. I don't know where the sound could be coming from. It's really annoying. It's not my gpu because it's being watercooled. And my psu is brand new. Help would be greatly appreciated. Thank you.
