Change your boot priority. If you can't figure something as easy as this out maybe you shouldnt be overclocking.
In my post I said my primary boot device was set to my hard drive, only when I increase the core clock the message error will show weird huh? It shows for a second and my computer becomes irresponsive but the fans are still running. Also I have to reset cmos to get it to work. I have tried many times with no success and now my computer time is not correct and I cannt sync it with one of the internet time websites.
