Hello, I have a Dell XPS M1530 and today it has decided to stop working!! When I try and turn it on...the Dell logo appears and the progress bar moves approx 1 cm and then stops (image attached) the fan is going and the harddrive seems to be making a noise too.  The only thing that seems to work is the power button, if I hold it down for a few seconds it will power down. I have tried swapping the ram around, and tried pressing various f keys as I switch it on but nothing has helped.  Any ideas??
