I've been working on this one for a while, bought the parts back on black friday, when I first put it together it wouldn't post and the processor error light stayed on on the MB. I tried swapping out the MB + processor and rebuilt it, I'm not getting any error lights anymore and everything seems to boot up fine, but it's still not posting. I've tried hooking up a DVI cable to the graphics card, as well as a VGA cable directly to the MB but I'm getting 0 signal, not really sure where to go from here.
 
may want to check the bios the mobo came in.
your CPU needs bios v15 or later.
