+1 on that recommendation. BIOS flashing is not something to be scared of, but reasonable steps should be taken to ensure the probability of success. Make back up, flash in BIOS using Q-Flash, have the machine connected to a UPS. The flash should have a purpose, resolve a specific issue, address a security concern, enhance the feature set or compatibility. Flashing just to have the latest BIOS rev available for your hardware is not recommended.
