you should probably do a fresh install, what you've got going there sounds like a file system nightmare. Here's what you do, put the xp pro cd in and boot to the windows xp setup. It'll come up saying something like press enter to start windows xp setup, then it'll say something like repair the current instilation or press escape to install a fresh copy of windows, you want to install a fresh copy. Once you get the the place where it asks what partition you want to install on you'll probably want to format the current one that way nothing from the previous installs accidently carry's over to the new one. After that simply follow the on screen instructions, it's relatively straightforward. Post if you have any problems, need a different solution, or need something explained more extensivly.
