I have a Power PC G5 quad running 10.5


I have the old apple cinema display with the adc to dvi adapter.

It has been running fine until....

Today, i had to unplug the display, and remove all usb attachments from the G5 and move the computer to have my room painted.

I just put it all back together, correctly, and when I power up the G5, the display does nothing, and i hear the copmuter power up, but after about 30 seconds, the fans start running full speed and don't stop.


And so without any monitor, i have to force shut down the computer (or let the fans run full speed for eternity...)

When I push the power button on the display, the power light within the button lights up, but goes dim when I release the power button. And the display never turns on.


I'm wondering what went wrong.


Any thoughts?


Thank you all!!!

PowerMac, Mac OS X (10.5.8), quad core
