Lol, that will teach you not to fiddle with wires unless you know for sure what you're doing.

Do you have any USB devices plugged in? I've heard several people say that sometimes XP has trouble shutting down when it has certain USB devices plugged in. (I know that in saying this, I invite a multitude of MAC users to bash XP, but I had to say it because it's true).

I had that problem a while ago with my keyboard, I just used the PS/2 adapter that came with it and it shut down just fine. Also, one of my friends said that MS had a patch for this problem. I never looked because I fixed it before I had a chance to.
