Pondering what has changed during your move and problems I've seen crop up after moving a computer to another location, I can think of two things. Your internet connection and the possibility that things came a bit loose inside the computer during transportation. If you haven't already done so, I'd recommend opening up the computer and reseating its components. Memory, power and data cables, GPU, etc. Vibrations during a move seem to cause connections to become somewhat iffy sometimes. I've also seen CPU coolers come loose so I'd make sure the cooler is firmly attached to the CPU by trying to jiggle it a little.
As far as the Internet/network, were there any problems while setting it up at the new location? In the US, it's possible to accidently insert a phone jack cable into an Ethernet port and damage the port, for example. I'm not sure if that's possible in your country. Or did you need to uninstall/reinstall network drivers to get things to work? Does the new ISP require the installation of software to use their network?
