    I use Fedora 13 on my laptop, that means I have the full control on my root and user accounts.
    After I started the computer this morning, I found it fails to login using both user and root account: it prompts I entered wrong password. I rescued it using installation disk using following operations:
    1: make a copy of /etc/shadow,
    2: reset my password as it should to be.
    After that, I made a diff between backup /etc/shadow and the new /etc/shadow, and found it really changed! That means the password was really changed by something!
    Could anyone give me some clue about what happened? Thanks a lot!

    I suggest you install rkhunter and/or chkrootkit to find out if there's malware installed on your computer.
