So the other day my speakers started to have very bad background noise. I power off my speakers and I heard a buzzing sound from the back of my case. So I unplugged my power supply and it stopped. I removed my power supply and plugged it into the wall and it still made the noise. While I told myself I'll just RMA it and I proceeded to install my original power supply an Antec 380w but before I completely installed it, I tested it out with only the power connected to the motherboard. And to my surprise it started to do the same thing but at a lower buzzing sound. I've tested the power supplies on a different outlet and it still made the same buzzing sound. Could my motherboard cause this problem or just bad luck and both power supplies going out at the same time?
*EDIT*
In the process of typing the message, the background noise and buzzing sound stopped.
