Choose boot then no post at all

[decen]

I just finished putting together this build;
17 920
asus rampage gene
3x2 patriot ram
750 psu
radeon 4850
I origionaly had no power at all then i wentg through the no post thread, after going over the conections i left the keyboard unplugged and went to boot again.
I got the message choose boot location press any key.
plugged in my wireless key board, had no luck so i rebooted, and now there are no beeps and no display.
the post reader that came with the asus stays stuck on "det dram"
any advice where i am stuck is it hdd issue or ram issue what do you guys think?

okay, i am now able to get into bios but its still not seeing my hard drive or dvd. I am think i need to be in sata ports one and two not the black one but i tried that. Do I ineed to have them hooked up by the sata power on my psu or is using the adapter ok? Ive tried both an am thinking that it is a bad board. Could you hook up the dvd strait to the psu and expect it to open? or does it need to be connected to the MB to have power.
