Music skips over network

I've had this setup for a long time. I have a computer with a 160gb drive in my room that's hardly competant enough to run five programs at once so I still use my computer in the dining room which is way more powerful. I listen to music off the 160 drive in my room over the network. Well it hasn't been until recently that the music randomly halts for a little bit then keeps going, usually halting four or five times before it stops. This happens as if the computer on the network is busy, but I've had nothing running and it's still skipped.

I've tried ending processes, stopping all torrents and closing my bt client (haven't ran it since yet the problem still persists), shutting off both computers including the modem and pulling the network cable, then starting everything back up and nothing worked.

put the 160gb drive into the more powerful computer.
