Hi Malibu,
From your reply to DB, it seems to me your HDD clusters/sectors are
corrupted/damaged.
Try this article and see if it will help:
How to recover from a corrupted registry that prevents Windows XP from
starting
http://support.microsoft.com/kb/307545
NOTE: you can copy/rename the config by attaching this HDD as salve to
another machine having the same Operating system Specs!

Also try to download the Hard drive Diagnostic tools from the HDD
manufacturer website and test the health of your hard drive.

HTH.
