This is embarrassing.. I clocked it down to 4.5GHz and 1.250V and now it wont turn on, it just says A3 in the right buttom. I read it was a harddrive error. Ehmm, can someone explain?
To get your system up and running again, clear the Cmos/reset the BIOS buy either using a button, if provided, swapping the CLR Cmos jumper and back again or remove the button battery for 15-30 seconds.
The reason you are having issues is most likely your inexperience with the bios settings. If you have not already done so please Read up on the settings in your BIOS and what they do, and Read up on how to OC a Intel CPU.
Edit: Overclocking is NOT an instant gratification Item. You must take your time and start small and work your way to big or run into issues. OCing is an art not a club to wack your mate with and then happily ever after.
