Are you being prompted for the password??
Anyways, you'll have to do a 'rescue' here to log in. Do that using 
your distro cd or a boot floppy if you have one.

Once you've logged in, check if you have a file called '/etc/nologin'.
If it exists delete it...that doesn't allow logins if it exists. 

If it doesn't, check your 'syslog' to see about the failed login attempts.
Maybe you get something there.
