I have an Intel DG965wh Motherboard.When I use new Active PFC PSUs; system tries to boot but it cant. Power fan spins for 3 second and stops and again spins and ....
but when I use old ATX PSUs there is no problem.
Please guide me.
make sure the 4 or eight pin atx cpu power pin is plugged in and your using the right cables. on newer power supplys the six plus two cables are for video power. most new power supplys use two four pin or one eight pin that clipped in the middle.
