    Power Mac G5 wont boot
    I bought a used Power Mac G5 1.6 yesterday, and was told that it worked. When I got it home, what happens is i push the power button and the white light comes on, the fans momentarily start for less than a second and then everything goes away. I have an unformatted hd inside because the previous owner kept his hard drive.

    Im wondering if it is a logic board or power supply issue. Ive tried different memory in it, and get the same result.

    after finding a good PRAM battery, that does not appear to be the issue. So, about every third time i push the power button the come with for a fraction of a second start to "whirr" but then stops. Nothing is coming up on the screen.

    Check and make sure the RAM is properly installed. If it looks good the odds are it's the motherboard.

    Then it's likely the MB. It could be the power supply I suppose....

    Frankly, it's not worth the money to fix it.

    Yes power supply at a guess and 1.6GHz G5, the first release of the G5 range, were a terrible machine which Apple quickly updated. Trust you did not pay more than say $40.00 for it. Shame you did not do a search of the threads first:-

    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    well you cant always do research first. i paid $50, so i guess ill just part it out, and sell the 4gb of Apple RAM that was in it, and try and get something for the rest.

    you wont get anything for it other than the RAM. there is quite a good community of case modders who love the G5 case, and are struggling to get their hands on one. I'd look online for some forums.
