I read OP more closely & see the mention of the red & green leds.^_^
What I would do now, and I am listing these in the order of what I think is least painful. And, you have not commented about any beeping or anything else from the system. So, I don't think the CPU is getting enough power or is not correctly seated.
1) is get a new hefty PSU from some local store. If this does not help, then you can return it so pay close attention as to how it was packed so you can make a good attempt at stuffing all back in. If this is the issue, you could still order a better PSU from 'egg & return the local one.
2) take the CPU out, check the socket with a magnifying glass ... although I cannot imagine that you will see anything ... but look anyway:\. Replace the CPU being just as careful as originally to get make sure that it is seated correctly before placing the HSF back on.
Maybe you could take a pic or 3 of your m/b installation with everything plugged in???
