how do you figure that your motherboard is making sounds?

capacitor squeal in your PSU

happened to me awhile ago too, i fixed it by upgrading to the titan x

Garbage / unshielded onboard sound card. Fix it by getting an external DAC or a dedicated soundcard.

If you're running Windows try changing your power settings.

If that doesn't help, replace PSU.

This.
Deal with it

Same thing happens to me. It's called coil noise. Slight vibrations from an inductor coil as power consumption fluctuates.

Sometimes it's possible to cure by potting the offending inductor(s) in epoxy. It may also reduce it if you disable frequency scaling on your CPU (BIOS may have a setting; Windows: set CPU minimum speed to 100% in power settings; Linux: set cpufreq governor to performance).

By listening for where it's coming from. You can move around and separate components.

That sounds more like a sound coming from your speaker when something causes interference in your sound card. This thread is about the board itself making noise, even with no speakers or even PC speaker/buzzer attached.

>tfw I used to be that fat
Jesus christ, I'm amazed how I still didn't just spontaneously drop dead.

You can also use this noise to extract encryption keys from a foot away using nothing but the mic in a cellphone, or further with a better mic.

To remedy this just use a class A tube power supply.

Where can I buy an ATX compatible tube PSU?

INCREASE PCI LATENCY TIMERS.

Thank me later.

>Hard drive starts clicking

getting a dedicated audio card didn't fix it
getting a new psu did

stop buying cheap psus

What the fuck is that thing in the pic

A very fat human with a very fat forehead.

The average American.

Can you hang glide with all that extra skin

It's your PSU first off, and it's because it's a cheap piece of trash.
