Speakers.

Suddenly my sound card has been producing an odd humming noise thru the speakers and i have no idea why or what caused this, the only recent thing i did was upgrade the RAM and a GRAPHICS CARD. why I think this is the sound card and not the speakers is because when I plugged in headphones (non-USB) they played the sound, however USB headphones play the normal sounds.

Steps already taken.

Turned Off/On.
unplugged all affected equipment.
Uninstalled and reinstalled Drivers in Device manager.
asked google.

 

fan on graphics card?

 

what about it?

 

The new card (graphics card) could be producing interference. This is the greatest downside with onboard chipsets. They are succeptible to any interference inside the case created by any other addon cards.

Swap the old gpu back in and see if the problem goes away.

A USB device is outside the case, and thus not affected.

 

That sounds about right, Is there anyway to fix it with the new GPU Installed? Im not ready to play around with the set up for about another month, don't want to accidently damage something and i would rather the new GPU take precedence.

You also stated that A USB is outside the case and not affected, would the speakers not fall under that category as well?
