Ok, so we all remember the power supply issues from the rev. A Powermac G5's. (...remember?) Well it just came back from the dead and bit me in the butt. I've been running a Rev. A dual 2 ghz refurbished PM for as long as they've been around. I've noticed that power supply noise in the speakers before... sort of small clicks and stuff. But it never annoyed me enough to do something about it, as I heard much of the time a power supply replacement did diddly-squat anyhow. BUT. Today I brought my G5 to a place I'll be staying for a while, and connected everything in the same fashion it had been at the other house. (G5 plugged into UPS backup, nothin unusual.) When I turned the computer on, however, a nasty noise started eminating from the belly of the beast. It sounds like high-power electrical lines buzzing... a constant never changing buzz that's very noticable even when playing music. Here are the facts: -It goes away when i put the computer to sleep. (therefore NOT the UPS.) -It is there when the computer is plugged directly into the wall (Again, NOT the UPS.) -My computer used to take about 15-20 seconds to sleep, now sleeps instantly. (since transport.) -I have a PCI SATA card installed. (random, though it may have to do with it.) Here are my questions: -Is this the problem that everybody was whining about? Or was it the small clicking noise audible in the speakers? -Could something have happened in transport? It was only a short drive, and i did all the handling of the computer myself, no dropping or anything.
