How incredibly frustrating for you. Just received all your new gear and this happens. I speak from experience here as I have had many issues with pc's over the years.
If you are getting no POST and cannot access the BIOS you may have killed the CPU also or in fact any of the critical components...let's hope not.
1) Make sure the cpu is properly seated and the cpu fan secured. Why? because I had exactly the same problem as you have now before.
2) Insert 1 stick of RAM in slot 1 or A1 w/e
3) Don't connect up all your hardware,just the GPU to see if you can see the POST and BIOS.
IF successful, then connect the HD. Don't assume your HD with OS on it will work. When you use a new MB this usually means a fresh install of OS..it did in my case. Worry about updating BIOS later if you can't see the bloody thing it's an RMA job i'm afraid.
ps
Get the Overclock video up Tom me ol' mucka i'm looking forward to it.
