It sounds like you have something shorting out the motherboard.  I would 
remove everything you can, all add-on cards etc.  Just leave a video card, 
unless video is on the motherboard.  I would disconnect all the drives 
too.  The idea is to remove everything, so you can check just the 
motherboard alone.  If the motherboard still won't power on, remove and 
reseat the RAM.  If it still won't power up, remove and re-seat the CPU.

I would guess something inside the case was moved around enough in your 
move to cause the short.
