If I boot into safe mode, I can use the G5 with limited functionality due to safe mode; BUT everything works in safe mode. I get video, audio, I can manage files etc. It’s only when I boot normally, I hear the chime, I get to the desktop, but seconds later, the screen goes black, and monitor shuts off indicating no signal going to the monitor. Once again, if I boot into safe mode, everyworks. Really baffled, not finding much help online either.
