Get a CPU that works with the board since day 1.
Was it a new brand new board or a 2nd hand one?
Im sort of surprised there is no life, no LED illuminated on it etc.
Check the PSU works by doing the "paper clip" trick, take the 24pin out of the board and sort the green wire to a black (ground/common) wire and this is the same effect as pressing the case power button, see if the PSU fan spins or attach a case fan to on of the PSU cables and see if it spins.
