[rnsrabbit]

So i moved my computer to a different location, before this it had no problem what so ever but since i moved this a few months later my computer just shuts down for no reason.. i bought new extension cables to plug it into the same socket that i was using before and it still doesn't work. What can i do ?

open it up and make sure nothing came loose. as always use proper antistatic precautions.
