This may sound redundant, but have you checked to see if anything shook loose during your move?
Just for the sake of certainty, I would start by double checking the power cable, making sure that it is in snug. Then make sure the PSU switch isn't off( believe me, its often over looked).
If all connections are secure, the next step would be to swap out the PSU if you have another one. It is certainly possible that something became loose during the move and is shorting your system. Try breadboarding to rule out a short.
