If you aren't experiencing any problems or compatibility issues with your mobo, don't worry about flashing the bios.
As for the mobo, use the latest Nvidia chipset drivers that support your chipset from the nvidia site. I'm pretty sure the latest ones will support your chipset, but take a look at the compatibility notes listed there just to make sure.
Question about your onboard since it's not specific in your sig: is it realtek onboard sound?
