You did unplug the unit before changing the CPU ?
Inspect the motherboard for bulging/leaking, or displaced capacitors.
If you have a keyboard plugged in & get a "no KB" error either the HB is bad, but you said you bought a new one, the KB PS\2 port has failed, the southbridge chipset has failed, or your reflashed bios has become corrupt.
As a kind of last resort try a new CMOS battery.
Other then that, if you can't get by the No KB error the motherboard is useless.
