It's very easy to use. First, undo any overclocking you've done. 2nd, download and unzip the bios file to a folder you can find. Next, start Asus Update and then choose 'update bios from a file' and point it to the bios file and hit next. Check the message that comes up at the bottom right part of the window, and then hit flash. Restart the system when it prompts you and you're done. Good luck. Peace.
