disconnect all cables from drives. reseat all ram & cards. try other ram & videocard. try clearing cmos as have found that to work sometimes to kickstart a stubborn system. get a new motheboard.
Pull out the battery in the motherboard. Place a screwdriver over the terminal to short the terminal out for about 10 seconds. Place the battery back in correctly. It may boot up now.
