Also even if I have 2 DDR's in there it should at least give me an error message on the screen right?
You have to have the ram in the correct slots- if they are wrong it says -incorrect memory will cause system no boot.
If it were me, I would unplug everything, then start again. Are you sure your processor & HSF are seated properly? Also pull out the ram, use only 1 stick in the correct slot. Be sure all of the front power connectors are correct. It's pretty easy to hook these up wrong. If you hooked up the sound wires- disconnect them for now.
Are you able to see bios at all or do you get the no signal error? If so, something is not connected properly.
If the online manual is better than the one that came with the board, print out the main pages of it and follow them.
Are you getting any beeps at all?
