1.6GHz G5 (mid-2003 model) not starting up properly anymore.
No red lights visible on the logic board or at the back of the machine. The start up chime only works very rarely, and the start up sounds are not what they used to be.The keyboard does not respond either, and there is no video on the display.
I have tried reseting PRAM and NVRAM. I have pressed the PMU button and put in a new PRAM battery too, but all these things have not made a difference.
The background to this is that I have had video issues for a while, whereby video would only come on after a few restarts.
Any advice on how I could, at the least, rescue the data would be much appreciated.
