Hi, I have a problem with my pc in that when I plug my power cable in I Do not get the red lights to indicate power, at first I thought the switch at the back was off but after checking it was on I have to take power cable in and out a few times and switch plug sockets and eventually the red lights to on and when switched on it stays in and works fine, last night the red lights came on so continued plugging mouse keyboard ethernet in only to find the red light has gone out, eventually after a min or so swapping plugs etc it came on I switched on as soon as I saw the red lights and worked fine any suggestions?
