    All of a sudden buzzing sound when I turn up volume about half way. Installed new PSU about a month ago all has been fine till this week.

    Have Denon A/V amp powering speakers. Connect Denon to computer with 3.5mm mini pin to Green port for sound back of computer. Also tried Green audio port front of computer same buzzing. I did check the cord with other devices through Denon amp. Crystal clear. No buzzing. Cord is good.

    I turn off computer, switch to OFF on PSU and, unplug power from PSU. Still have buzzing sound. Hard to play games with buzzing.
