Can anyone help me troubleshoot me R3E?

I have 6gb (2x3gb) Corsair dominator 2000mhz ram installed, a xeon 6 core CPU, and i want to run a revo drive and two 580GTXs in SLI...


But I keep getting this error on boot where the VGA and Boot device LEDs stay lit and obviously no post.

I have tried using a back up VGA, same problem, tried without the revo drive with just DVD drive installed, no post.

Any ideas?
