@ blufire I just turn off the PSU switch or unplug it if you dont have one

let the ASUS light turn off at the bottom and turn it back on and power it up

it should start if it was an Overclocking that failed to reboot ive done it many times

and cas6 never worked for me on this mobo its been along time since I tryed it but it didnt work

why dont you use the x9 mulit ?
