proskater123 Posted May 19, 2012 Share Posted May 19, 2012 So I am working on a mac g5. I have not worked on very many so my knowledge is limited. So here is the issues and steps I have taken to try and fix the issue. When the mac was brought in it would: Chime the mac boot up sound Not show any video fans will start normally but after awhile would spin up to full rpm What I have tried: Reseting the pram Reseting the pdu checked the onboard battery for 3.5 volts started without the battery tried new ram After some more diagnosing, the Mac will start once out of every 10 times it starts. (This is just a rough estimate. Not actual) Even when it does boot after about ten minutes it will freeze, and fans will be at top rpm. Then when I try to reset it, sometimes it will not boot with no mac chime, not boot with mac chime, or boot with mac chime. It is very random. I am very clueless as I have not had many times to work on a mac. What would you say is the problem? The logic board, cpu, pdu or something else? I have disconnected both hard drives and still received the same issue. Quote Link to comment Share on other sites More sharing options...
