Run one gpu only with only one psu, and borrow a buddies board and cpu if you can, then swap parts until you get something working. Test the psu and gpu with the known good board/cpu combo before swapping the cpu/board around. Bear in mind though that you might fry your buddies board and cpu if the board is totally hosed so just be careful. If you have a DMM read the debug voltages on the board to see if any of the voltage regulator circuits on the board are dead.

Thanks stren. It good to know that the CPU led may be mis-leading me.
