If for what ever reason your OS is broken, a much easier recovery can be made if you had a copy of the eSupport Folder. The contents of this folder can NOT be completely replaced from programs and drivers on the ASUS Download Center. Some of the software within the eSupport Folder does not belong to ASUS. ASUS pays a vender for its' use. This means the software has the ability to authenticate your laptop before it can be loaded.
