[QUOTE="jasongoldworthy, post: 1814816, member: 395464"] hi guys I have been given the above iMac from a friend they said it wouldn't no longer boot so I took it apart and discovered just 2 of the diagnostic lights come on when you press the power button the 1st one is on as soon as you plug it in but the second one then comes and and stays on but there is no chime no nothing, now if I remove the ram and boot it I get a single beep that means no ram if I remember correctly I've tried the ram in my 27' iMac and its fine so its not the ram thats bad, any suggestions on what I can check next ? could it be a bad GPU ? or even a bad logic board thanks [/QUOTE]
