Your post did not show before I posted. AS you are hearing Beep Codes, have I got the wrong MB? http://www.evga.com/...132-LF-E655.pdf
Unfortunately there are no published error codes for what you are hearing. The stop at 2E LED is no VGA device detected, it should change when you install the GPU.
Yep, try entering BIOS to load optimal Defaults. Your RAM has been deteced.
Have you the keyboard plugged into the back of the case? When you Boot, do you see LEDS on the keyboard flash?
Hope you get a good sleep.
