You can follow the advice given by the others to reset the password, but you cannot install OS with a USB CD-ROM. You, most definitely, will need to change your CD drive before you can install a new OS.
I'd like close this one with a "Didn't see that one coming" Removing the Cmos battery did nothing. And as it turns out there was nothing wrong with the CD rom, I had a stop code that indicated hardware failure.
It turned out to be the memory that was causing problems, I never thought to check because it was a new chip. I guess live and learn, i replaced the ram and installed OS just fine.
