I have tried 4 different cpus and 2 differnet motherboards and the boards just wont post. I now have a brand new motherboard and cpu and new memory and it still wont post. The board takes a 24plus 4 pin power supply. The power supply is the only thing they have left in common. I do get power to the board as the cpu fans fun no problem. I was told it could be a short in the power supply. Is it possible I need a new power supply. This one is less than 6 months old.
