Since you have moved 160 km from your previous location check the power source voltage if it is the same as the previous location. Disconnect the power cord of your computer and open it. Examine the connections. Try resetting the ram. video cards, power cables, etc.
Hope this help.
With the side off the machine check and make sure the cooler fan is running. Check and see if the cooler heatsink was loosened in your move.
There is a chance, during the move of the system, that the heatsink-fan unit has separated from the processor and the processor is thus not being cooled properly. This can happen if one of the pins that holds the heatsink-fan unit to the motherboard has released. You should try removing and then reattaching the heatsink-fan unit to ensure that this is not the case...
