Static problems with my soundcard

[bluetoast]

I recently bought a nice pair of krk 6 g2's. The first thing i hear when i plug them in to my sound card is a a pretty consistent, audible buzzing noise which i don't hear on my z-2300's. Initially i thought this was because of dirty power so i tried plugging the same speakers into my ipod and no problems. Does the power supply might have anything to do with it? My operating system is Winxp pro 32bit.

Fixed, had to turn the volume all the way down on each speaker.
