I recently built a system similar to yours (see sig).
My first board would post OK (signaled by a single beep from the speaker). It would NOT get into the BIOS and display anything (neither by my video card nor the built-in video).
I had to RMA it. The second board worked fine and I am very pleased with it.
In reading the reviews on the Newegg site (where I purchased the board) it APPEARS TO ME that these boards have quality problems. Some work great - some are DOA.
The best advice I can give is to remove the board from the case and place it on a piece of cardboard. Leave nothing but 1 stick of RAM, processor, cooler and video card. Try it that way and see if it gets into the BIOS.
Note that if you use a video card that it fits snuggly down - the cardboard sometimes interferes with this (drove me crazy until I raised the edge of the cardboard a bit).
Plug in BOTH power connectors, case connectors (e. g. power, speaker, reset, etc) and try again.
If it fails - RMA the beast and hope you get one that works.
