ok i think i found a big problem here my motherboard has f7 bios version and my cpu needs a f9 bios version how can i update it whitout destroy my motherboard?
Go to the manufacturers site of your motherboard.
Search for BIOS updates and download it.
Extract the zip file, open the folder and open the executable.
Further I cannot say, outside of following any instructions you can find on the site of Gigabyte (I couldn't find any).
Most important is to make sure your pc won't crash while flashing.
I had my BIOS flashed as follow
Downloaded the BIOS and extracted the zip file
Opened the folder and opened the executable
Followed the instructions in the installation package
Restarted my laptop and kept it charged (in case with a problem with the battery)
