Windows 10: System security code locked out

I bought a used computer and it was factory reset. When I booted it up it was fine. The next time I booted it up it has a password for the BIOS. I can not reset anything because when I go into my security settings it is not highlighted. It says password set. I have spoken to previous owner and she said she never set a password for that. How can I get this resolved so I can use my Dell computer

Security code = Lock code in 9300

security code and lock code is the same thing.

S60 handsets seem to say lock code and S40 handsets say security code.

S80 handsets seem to us a mix between both references

 

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

Security code = Lock code in 9300

In Nokia 9300 Cover phone asks Security code when I set up Lock code in use by Sesk > Tools > Control Panel > Security. Manual says very little about Security code. In panic remembering PIN & Security/Lock is a challenge.
