My computer was working fine today until I turned it off to install a 3TB Seagate hard drive.
I tried to boot it once and the fan led's came on for a split second and then went off again...so I pressed the button again thinking I didn't hold it long enough...same thing.
I opened the case and unplugged the new hard drive and tried again, this time all of the fans came on at full blast and I could hear the hard drives start spinning but no beeps or video showed up.
I ran through all of the tests on the "No POST", "system won't boot", and "no video output" checklist and still have the same thing.
Tested it with another power supply...still the same thing. There's a debug led indicator on the bottom of my motherboard, and that's not coming on at all.
I am looking now for a new motherboard thinking that's the problem, and didn't want to just drop $200 if that doesn't actually fix my problem.
Thanks for any assistance!

I tried hitting the clear cmos button on the motherboard. I also removed the battery from the motherboard for about 3 minutes and I also tried unplugging the computer and holding the power button in for about 30 seconds.
I would personally order a new board and while you're waiting for that to come in either return the new harddrive you bought (assume its faulty and will cause the same outcome if you plug it in again) or RMA it.
