In a systematic approach to fault diagnosis (that?s trial and error to me and you) I took out the second hard drive, both CD drives, second graphics card, sound card etc until I was down to a basic system but this still didn?t work. I then disconnected the hard drive and replaced it with an old one that, although worked, wasn?t being used and guess what? It worked! Looks like I have a duff hard drive on my hands.
Anyone want to buy it?
