Different room movement; Could be too many electronic / powered devices on that 'circuit' depending on the 'layout' inside the wall (what hooks up to it - easiest test, turn off the 'breaker' for each one and when you see what plugs don't work, they are all on the that same 'circuit'). Second consideration would be some cable got loose inside the PC. Reseat all power connection points to make sure they are firmly seated. Same for the Video / other cards, that may have 'jostled' loose during the 'move'.
