Have you used a multimeter to test the PSU ? If you try this look for instructions PDUs do not like no-load conditions. You cannot detect a rancid burn smell in the PSU ? No blackened or brown parts ? A used unit from the swap list will be much cheaper than a new one or having it rebuilt. I don't know about converting a standard unit. you could try a web search using the PSU swap out parameters. It is doubtful you could repair it yourself. A zapped power handling diode or condenser is possible. But again you would probably need to have a pro solder it in. you have to find it first. >From what you describe this machine should smell bad inside the case and / or PSU . But the smell dissipates over time. Such damage should be easy to see and smell. -- Adrian D'Alessio aka; Fluxstringer fluxstrin...@gmail.com http://www.flickr.com/photos/fluxstreamcommunication/ http://www.facebook.com/FluxStringer http://www.linkedin.com /in/fluxstreamcommunications http://flux-influx.blogspot.com/ http://fluxdreams.designbinder.com/ http://twitter.com/FluxStringer -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
