Troubleshooting advice would help too, but I am fairly certain I have a PM G3 beige minitower that is on its way out. Fresh PRAM battery, all expansions removed, minimal system connected (with the exception of a SATA card later on). Power supply voltages are golden, within 10% or less of the rating.
Symptoms:
Symptoms:
- No chime at boot but it does boot. OS 7.6.1 and 8.0 can play audio through the speaker when using them in a Norton Utilities envrionment, so I know that part at least works.
- Boot RAM test takes a very long time. After a long period of being unplugged, nuked PRAM or otherwise, sometimes it does not show video at all.
- Intermittently responds to ADB power-on/power-off keypresses.
- CPU barely heats up, contrary to my experience with the G3 in the past.
- Sonnet PCI SATA card, designed specifically for this Mac, being used as a disk, and OS 9.2.2 can see it but OS X of any version cannot.
- In fact, OS X can see IDE disks on the motherboard's controller, but no SCSI disks, or intermittently it can see SCSI. OSX install takes an eternity to complete, which in past runs with this computer, is a new problem--usually it takes about an hour at the most, with this taking up to 3 hours now if it's installed to a CF card under IDE.
- OSX 10.1 and 10.2 can complete their installer, but 10.3 kernel panics despite being rated to run on a G3.
- All RAM sticks test fine in other machines.
