Trying to format laptop

Hello!
This is my first time in this forum,
and I have problems in my Laptop as I try to format it blue screen always appear and I have try to consult with my fren they told me that "I have to update BIOS" It seem a strange word to me so I request any one can help me for this problem.
Thanks.
 
By updating your BIOS, your friend meant for you to go to the web site of the laptop manufacturer and download the latest BIOS update under Software/Drivers.
What kind of laptop and model please?
