When the system locks up in the BIOS, that isn't a good sign. You could try doing a proper reset, using the jumper on the motherboard, and then see how it goes.

If you still have the problem, I personally would start by checking the RAM in pairs, as this is a common sign of a bad RAM stick.

Also, since you moved, you may want to remove and reinstall the heatsink on the CPU. I would also check around the mounting holes for any damage.
