Hi!

So I built a pc(bought all components and same company put them all together too). It was 4 days ago, when I got it. And yesterday I started hearing weird noises from the computer.. And what's more weird about it, when this noise comes from my pc, then at the same time there is a noise in my speakers/headset.

Notes:
I have 5 plugs plugged into one extension cord(two lamps, speakers, monitor and pc)
It starts at random time.
It stops randomly.
I used HD Tune, it said that everything is okay.
The more I turn volume up in my speakers, the louder the noise from the speakers.
It starts slow and then this crackling or sth gets faster randomly and then stops, and starts again..
Also one USB 3.0, audio in and mic in holes dont work in the front panel of my pc, but USB 2.0 hole works.

Specs:
Intel Core i3-4170 3.7GHz
nVidia GF GTX750 Ti 2GB GDDR5
8Gb Kingston HyperX Fury RAM
MSI H81M-P33 Motherboard
Xilence ATX Performance C 500W PSU
Western Digital Caviar Blue 1TB SATA 7200RPM

Noise:

Turn the volume up to hear it.(It's not a screamer, I promise)

it could be our power supply, just like when an alternator in your car is going bad it causes a whine in the stereo. a powersupply failing has been known to cause similar issues. get a powersupply tester and make sure it is working ok and not over volting your computer that can damage components.

Well it stopped right now, it isn't there right now. It starts randomly, and like I said, it starts slowly, and then it sounds like something speeding up, going faster, maybe some fan or disk or something, but it comes from the speakers at the same time as from the computer.
