New build-usb speakers are making crackling/high pitched noise

My guess is that it has to do with the case or motherboard.(i tested the speakers on another computer and it was fine)
case- nzxt gama classic
mobo-gigabyte z68ap-d3


OTHER PARTS- doubt any of this is the reason
speakers-shity 10 dollar speakers from microcenter
cpu-i5 2500k
ram- 8gb patriot
psu- 600 watt ocz
gpu- saphire 6870
hd- some 120gb i pulled out of a broken netbook( will be upgrading soon possible ssd?)
monitor 22 inch hanspree 1080p(possible interference)

PLUGGED INTO IT
speakers
monitor
wireless keyboard
wired mouse
ocasionally phone charger

MORE INFO- When i plug in my speakers it makes a crackling/buzzing/highpitched anoying noise. Even when i just touch the tip of the metal piece to the green port it makes the noise(not inserted). This happens on the front case port, the motherboard port, and even a sound card port.

STEPS I HAVE TAKEN
1. reinstalled driver
2. tried multible ports INCLUDING a sound card(found lieing in an old computer)
3. switched usbs
4. taken out keyboard and everything else that was plugged in
5. a little bit of inside rewiring of my case (while i was installing some fans)

I feel like its some sort of interference. I just have no idea from what.


Any ideas?

thanks

  1. That's actually normal for the AUX cable to make that noise. My computer does it, when I hook my iPod up to my parents' sound system it does that, when I plug any AUX device into my car it does, that, you name it
  2. but wheen i plug it in to anyother computer it doesn't. It even makes it when the sound is muted (on my computer).

    Sounds like some bad speakers then, that's the only thing I can say.
