I went out yesterday and bought a new cable and it is still doing the same thing. On the back of the computer it is still showing three green lights and one yellow, and dell says if that is happening then to make sure there is a connection from the hard drive to the system board. Everything is connected with the hard drive and it still does it. So I hooked the old hard drive up and all the lights turn green but now I get a message on screen saying that there is a disk error and that i should press ctrl alt delete to restart and I did that and the same thing keeps happening.
