my toshiba starts up and and goes to a black sceen with a blue box needing a password what kind of password is thhis


Bios PASSWORD can be reset by resetting the BIOS. Take unit to a service place like geek squad and ask if they can clear the CMOS. If you are techie enough you can do this yourself. By removinng the CMOS battery for a few minutes (not the main battery) it is a button type cell.
