Have you tried resetting the bios? Plus unplug the power supply and hit the power button a few times. Plug it back up and see what happens. If nothing, my guess would be the board or power supply. You got another power supply you could try?

You can do a couple things here.

1. Try resetting the cmos by removing the motherboard battery. Unplug power from power supply, remove cmos battery, press and hold the power button on the case for 10 seconds, then wait 10 minutes. Then reinsert battery, reconnect power and try booting up.

2. Check all your power connections, when replacing the hard drive you may have jiggled something loose. Check main motherboard connector, 4/8 pin cpu power connector. Make sure video card if using dedicated card is securely in slot. May help to remove and reinsert video card.

3. I've seen bad hard drives cause this sort of issue, try disconnecting both power and data cords to the hard drive and see if the system posts.
