Its not loud, but you can kinda hear it in the background, and its starting to get on my nerves.
Its constantly buzzing when the power plan is set to High Performance, but when its set to Balance, i can only hear it when i'm scrolling through pages, folders etc.

What is causing it?

Motherboard is ASUS M5A78L-M LX
Power Supply is Chieftec A-80 650w Bronze
