Power Mac G5 main light just flashes.
I have the same problem. Nothing comes up on the monitor. I basically have got the mac pro g5 from a house clearance. I was just helping out someone & spotted the mac plus monitor. The person I was helping is just into furniture & isn't interested in computers at all. From what i can see inside the hard drive is missing & the ram. I have an iMac at home & have no idea about these towers.
Main light on the g5 flashes once every 5 seconds for 27 flashes on the 28 flash it flashes 3 times in a row.Then it will start the process again. Fans are running non stop
nru4 are the last letters & number. Just ordered a dvi to mini dvi so I can connect the monitor to my iMac, just so I can check the monitors fine.
Also got a 250gb hard drive. still need to get ram though. one flash is missing ram, Im wondering the 3 flashes might be missing hd.
Is this a good question?
