If unfortunately, the system's frequency that you are selected is not
functioning, there are two methods of booting-up the system.

status. All the CMOS data will be loaded as defaults setting.
Method 2:
Press the <Insert> key and Power button simultaneously, after that
keep-on pressing the <Insert> key until the power-on screen showed.

It's strongly recommended to set CPU Vcore and clock in default setting. If the
CPU Vcore and clock are not in default setting, it may cause CPU or M/B damage.
