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.

1. Check that you aren't using Internet Explorer in either computer, especially the remote one.
2. Check that they aren't completely busy (CPU 99% or 100%) because of some other reason (like having used Internet Explorer in the past).
3. Make sure your network is not saturated. Tell others to stop the porn torrents and all for a bit; stop yours too; wait 1 minute after you've closed BitTorrent before proceeding.
4. Check that your network is fine. Try copying a file from one computer to another, and calculate the transfer rate. It shouldn't be less than half of your network speed. (More information on this on demand.)

If you haven't used Internet Explorer, it's probably the cable.
