FF means fully functional, so you're okay there. If there was something wrong with the mobo you'd see an error code on it.
First of all you definitely want to use a PS/2 keyboard (the purple connector) when you first boot it up. USB sometimes doesn't work.
Second, make sure your graphics card is in the right slot.. It should be in the slot closest to the processor (See this article for pictures:
