Turn your CPU on and hit f8 rapidly, DONT STOP. Eventually you should get the boot menu screen. Choose to boot into safe mode. You should be able to get in and backup your important files (using Cds, floppies, whatever you can) just get your important files backed up! You may never be able to get in again! Now that you have your important files backed up you can try some things. First off, power down your cpu, unplug the power cord from the back, open it up, look for a silver circle that has a + on it. This is called the cmos battery. While your computer is unplugged take the cmos battery out. Put the battery back in. Now there shouldn't be any passwords. If you still cannot get in you may have to format, in which case you should try to get in via safe mode so you can back your stuff up.
