Bit torrents killing my internet?

[Dr. Boogie]

For a while now, I've been wondering why my internet connection keeps dropping off for seemingly no reason, and I've come to the conclusion that somehow, bittorrent is the culprit. I don't know why, but my connection just quits working after a random amount of time, and without any messages from Windows about there being something wrong with the connection.

Anybody know about this, like how to fix it, or does this have more to do with my ISP?
