M17x R1 not displaying on lcd or external monitor

So here is the situation. I'm in the middle of an M17x rebuilt buying all the parts on ebay except the motherboard which i bought straight from dell. I didn't install speakers or the optical drive haven't even done a windows install yet. I powered the system up for first time with 2 gigs of ddr3 1333 ram. powers up no led codes displayed keyboard stays on and touch buttons all stay lit up. Does this mean my system isn't posting? I get no display on vga port or on the internal monitor. please help.
