Well, as I mentioned, I did install a new PRAM battery, though the "old" one measured at 3.6v. Status update: as suggested, I disconnected the HD and started. The machine showed the flashing ?. Put in an OS 10.4 install disk. Machine booted to the DVD. Shut down and reconnected the HD. Booted to the DVD and called Disk Utility. Drive was visible but attempts to "Repair" failed. I erased the HD, with "zero out" as the option. Installed 10.4 and updated to 10.4.11. Seems to boot OK. The HD may be "flaky" as suggested, but the rest of the machine seems OK. I wasn't looking forward to probing the power supply pins as a "failure" there would be $$ that I would rather put to a new machine. If the rest of the machine is good, I will try finding a 2 or 3 Tb HD and give it a home. Thanks for the assist.

G5 Troubles
I picked up a G5 dual 2.0 PCI-x a couple of days ago. The hard drive had been wiped, but it started right up to the flashing "?" I stuck in a retail 10.3 disk and installed and then upgraded to 10.4.11. It ran for a day or so and even successfully started Classic. Then, after a day of running properly, it won't launch. It does start with the proper "Chime" but then shows only a blank screen for several minutes before the fans gradually increase speed to max. I have: Reset NVRAM in Open Firmware: No change. Reset PRAM; No change. Installed new PRAM battery: No change. I opened it up, wiped all the fans clean, blew out a bit of dust. No change. I am looking for ideas from anyone who has more experience with this machine that I do. I have taken apart and put into operation most other types of Macs, from a 128 through DP Mirror Door, and a few PowerBooks, so I thought I might be able to "save" this machine from the scrappers.
