New build not working!

Hi everyone. I just built my first computer and I turned it on for the first time and got no signal on my monitor from one of my graphics cards (I'm running two 6770s in Crossfire). So I took apart my computer and I think it is because of my CPU. I have a red CPU light (all the others are green) on my Asus Crosshair V Formula motherboard and I got a little bit of Coolermaster CPU paste (came with a Hyper TX3 cooler) on my CPU pins (AMD Phenom II 1090T) and in the socket. I also booted the computer up without the CPU, and the exact same thing happens, so I think the CPU may be dead. Is this the source of my problems and, if so, how do I fix it? Thanks
