This is not helpful...
We need to know if the your Windows was OEM or RetailEDIT:
First like getochkn
said, you should't try overclocking before you have the system running up properly
So reset the bios settings to default.
Change the boot order so that your hdd which has the OS installed is listed first.
Note that it's still likely you will need to re-install Windows since you changed the mobo + cpu
