Reinstall your system. =)
Seriously, this isn't Windows. Reinstallation is always a last option, always, when using Linux. If your not going to post anything that might actually give alternatives or solutions to this problem, just skip it and go on to the next thread/post.
For the problem, try booting your system into single user mode to change root's password, etc. Or you can use some other form of a boot disk to change the password, etc. Usually distro's like Mandrake come with a rescue option on the cd's, you can possibly boot back into it and at the boot screen see if it has a rescue option.
