Annoying buzzing sound from audio output.

[Energize]

Often when connected to my pc I can hear a buzzing/electronic sound which is more pronounced with certain activities, for example right now when transferring files from one drive to another even with the sound muted. Will getting a soundcard stop this issue?

I also notice that with the sound muted in windows, I can actually hear the sound very faintly through the headphones. When using one of those plug in sound level controllers where you turn a dial, the headphones are silent however.

same problem
its hard drive noise
i think my sound card is broken (asus xonar dg)

Funnily enough I just actually removed my hard disk last night as I've replaced it with an external one I only connect when I need to make backups. Hopefully that will remedy the problem!

unplug the front panel usb headers from the motherboard,then see if noise stops

Will do, I noticed the buzzing from the front panel was particularly bad.

Disconnected front panel (probably a good thing since sparks come out if I try to plug a usb device in) and with the hdd removed there's still no difference. One thing of note is that the noise changes pitch depending on what's being displayed on the monitor.

Will try disabling power save mode next.
