    G5 hardware failure, help!
    Hello people

    My inlaws have a G5 rev1 and it has had a hissy fit today and now will not boot. I am a pc repair technician by trade but have very limited knowledge of Macs themselves.

    So they seem to think it could be a hard drive failure but as they system is not posting im a little dubious (on a pc id likely get a bios screen/post even with a failed drive) so i was wondering what you guys thought?

    Power light turns on and after a while the fans kick in apparently if thats any help.

    Any input would be a big help!

    Is this the REV 1 iMac G5 system? The one with the built in display? Some of the REV 1's had a recall for bad capacitors if memory serves me correctly.

    Could be. I know some of the very first 1.6 or was it 1.8Ghz G5 Power Macs had some issues. I will search around and see what I can find. Been a while.

    If the Hard Drive dies or is not there normally a Mac will go to a gray screen and show a drive icon with a Question Mark in the middle.

    Righty, ill tell them to prehaps try to get it to do that first off by removing the drive.

    Pretty sure it wont be the drive tbh unless its died in such a way its stopping the machine posting.

    That said don't G5's of this age use rubbishy Maxtor drives.......
