hi ,
i'm so sorry about this late
it was because of two reasons : the approval of your PICs and my meeting
at all it's time to update your BIOS
first go to HP drivers website
then select your OS and look for BIOS then download it
note : the bios update can be found with the same versions in 8 and 8.1 and 7
now start the setup
it wil ask you to choose : internal or USB falsh
i prefer internal setup
next next next
till it tell you
don't turn off your PC while updating or change the power source
**be careful while updating your BIOS
