Has anyone else had their PC plug fuse? Ours fused about a week ago for the first time ever - we leave it plugged in all the time, even if the PC is turned off. The PC was turned off last night and the switch at the wall was off too. When I turned it on, the lights came on, but i went out of the room ana when I came back, it was completely off and when I moved the plug, it sparked! Does anyone else have experience of this?!!
