PROBLEM SOLVED BY ACQUIRING NEW COPY OF WIN XP. IT WAS THE CD THAT WAS FAULTY Had it working for a few days and realized tonight that I had it formatted in fat32. Since I need to hold files bigger than 4gb I thought I re-format the drive and do a new installation of windows and now I get the error message: STOP: c0000221 Unknown hard error /ntdll.dll I found this out about it: To resolve this problem, obtain a new copy of the corrupted file or reinstall Windows XP. If you continue to receive any one of the error messages that are described in the "Summary" section after you reinstall Windows XP, a hardware problem or a network problem may exist.
