Noob Question-Bios Updating

[sidthesexist]

OK due to a Blue Screen/Instability problem it looks like i will have to update the sound drivers on my computer. But to do this i will need the latest Bios revision. Having never had to update a bios before and there being several updates available, do i need to install each in the order they were released? Or do i just install the newest and will this have all of the previous updates as well? Board is a GA-Z77-D3H by the way.

Thnx

Thnx, System isn't overclocked so shouldn't be a problem there.

Thnx All, done now and upgraded to the F23 bios, was a heart attack moment when trying to reboot to windows afterwards and getting constant blue screens. After a snoop in the bios i found that the onboard graphics had been switched back on which i believe (hope) was causing a conflict with the installed card and causing this? Seems to boot fine since the onboard was disabled. Now to see if this has cured the crashing problem in games..
