Why do you want to flash the BIOS? unless the BIOS update has something that you can't do without, then don't do it. Why take the risk of bricking your motherboard if there is nothing wrong with it.
Saying that a couple of extra steps you should consider 1) Make sure that any overclocking is removed and the BIOS is in its default state before updating. 2) After you have done the BIOS update don't forget to clear the CMOS memory correctly. This is by using the link on the motherboard with the power cord DISCONNECTED.
