Doesn't sound funny to me. Does anyone else have physical access to this system -- especially when you're not around?
You say that you've been using "the same 4 passwords for years now." For everything? Is it possible that someone else knows your passwords?
You might want to at least consider the possibility that you've been sabotaged deliberately. Easy enough for someone with a few seconds unsupervised access to that machine to do if they've figured out the password.
Insofar as pulling the battery is concerned, that works on most older systems. There are some systems that this won't work on, and others where it may work but you actually have to use a soldering iron to accomplish the disconnection (not a worthwhile risk unless you really know what you're doing because of the possibility of heat damage to components).
If you run into a wall you can always have the OEM (assuming that the OEM isn't you

) get past the password for you.
Just one more thought. If this BIOS supports separate startup and BIOS setup passwords you might try using whatever key combination is required at POST-time to try to get into setup. Maybe one of your passwords will work to get you into the BIOS setup routine. In that case you should be able to reset the startup password.
