Please help me get rid of frustrating audio interface noise! I have a new pc and a presonus firestudio mobile audio interface. When I plug in the firestudio via firewire there is a pulsating sound and some buzzing sound.

When I just use the firestudio for playback of films or songs through my active monitors none of these sounds occur. They only occur when I try to record something through any of the inputs.
People tell me it is a ground loop problem. I have no idea how to mess with cables or anything to solve the problem. I don't think I can use a ground loop isolator because there is nowhere in the chain to put it as the chain only consists of cpu--->firestudio and i'm listening with headphones without monitors plugged in. Some people say I need to break the ground on the mains plug for my pc but I'm not sure how to do that either.
I tried a friends focusrite interface which was usb, it was even worse!
Any ideas? I will be eternally grateful to the person that helps me fix this!
