when i start up my macbook pro i have the problem that nothing happens except the screen goes the familiar grey that it normally does except that no little apple logo appears in the centre, sometimes the computer will switch on without any problems but most of the time nothing happens.
the chime sounds still occurs but nothing apart from that and the grey screen. the computer also switches off really easily like as soon as i tap the power button.
