The next thing to check is your Motherboard. Remove all devices (hard disk, cards, memory, etc) just the motherboard connected to the power supply, just to see if the motherboard is working right. Your should be hearing a beep sound indicating that the board is alive. If yes, you may reinstall the rest of the devices you removed.If no, replace motherboard or processor.
