sounds like you are referring to the system password and not the OS password. If so, locate the 10-digit service tag on the bottom of the computer. Let us know what your number is.
The person who setup your system will have it (if its a company system).
You could try your password if you are the one who installed the OS. Otherwise you may need to re-install the OS, apps & your stuff hopefully you have a backup.
