Have you tried to run the backup or bios 2? Your board comes with 2 switches for the bios.
yes, for bios 2 i can boot and normally.
=============================
edit.
Problem solved
1. Shut off the power supply using the switch on the back of the PSU, wait 10-15 seconds.
2. Press and hold the case Power On swtich, then while still holding turn on the power supply from the switch on the rear.
3. Still holding the case power on switch, the board will start, once it does release the case power on switch and shut off the power supply via the switch on the read of the unit. (Do the latter two parts as quickly as you can once the board starts)
4. The board will shut down.
5. Turn the power supply back on using the switch on the rear of the unit.
6. Turn on the motherboard by pressing the case power on button.
but when i try to Overclock again and fail, problem is back and can't solve with Clear CMOS.
i am using bios F7.
could this be the bios isue or hardware issue?
