|Is your PC working?|
If it ain't broke don't fix it.
Bios updates should only be performed if you have a specific problem that is addressed by the bios update.
If you get it wrong you can turn your perfectly good motherboard into a doorstop.
"My bios has been recently out-dated" is not sufficient reason to take the risk.
Do you have a problem that is addressed by this bios update?
