    Is there anything in the CD or floppy drive for this computer? If so, remove it as this may cause problems also.

    Was the PC being worked on before? Just to be sure, select the option to view all hidden files and operating system files to see if there are any other files in the root folder.

    From the sound of it, you might have to reinstall Windows if it still won't bootup. You can try running a repair install which will install over itself, but I recommend doing a clean install. It's just a cleaner way of doing things and you don't need to worry about problems that may arise from an "upgrade install". If there is any data that you can backup, do so before reinstalling Windows. If you only see the Windows folder, then you are most likely out of luck as XP stores the user documents/files in Documents and Settings folder in the main/root drive.

    I don't know that you can. I can think of two possibilities at first glance:

    1. Serious malware has deleted things.
    2. A hardware error has caused a hard drive corruption, thus losing data. This has happened to me.

    Best course of action (if you wish to keep the machine) is to get another hard drive (maybe bigger) and reload Windows. Then slave the old drive and recover what you can.

    Sometimes an unclean shutdown (e.g. due to a power outage) can cause filesystem corruption, but assuming NTFS is used, it is fairly rare for such serious corruption to occur due to the use of the transaction journal. Windows 2000 is in my experience more prone to this than XP/2003 and later.

    In any case, running chkdsk /f (from another machine or using Recovery Console or similar) may help. It also may very well not help, but it's a simple thing to try before having to do a reinstall.
