Have you tried a F9 on boot?
Before you do anything back up your eSupport folder to a safe location. Is there a serious problem that you can't fix that you want to restore to factory condition? If not there is probably no advantage to doing this.
eSupport folder contains all your drivers and software some software that is not available on the Asus Support Download site. So do not lose it.
