If you are still around, can I suggest switching everything off. First check the connection to the wall socket, then each connection you have into your 'power protection' bar. OK, they're allright. Now check every connection you've got to your PC, Monitor and Printer if attached. Then switch on power and boot up, and I've got my fingers crossed. Please do not skimp the checks.
While you've got the box open, make sure all the connections to the mobo are firm - something may have come loose during the move - and also make sure there are no loose screws etc lying on the mobo and causing a short.
