Do you have at least 512 MB of RAM?  Given that the computer came with Windows 2000, I think there's a good chance that it doesn't, in which case it has no business running Ubuntu.  In my opinion, Ubuntu is bloatware.  It has its merits, but running on very old computers is not one of them.  Ubuntu is roughly as resource-hungry as Windows XP.

Try a lighter distro for rescuing files, such as Puppy Linux, antiX Linux, or Damn Small Linux.  I know for a fact that Puppy Linux can recognize Windows files.

If booting from a live CD doesn't work, then try booting from a USB drive instead.

I have tried many different things, including the video card corrections, but it stops at "checking 'hlt' instruction..."
