Hi,
This is a generic fixit for PowerPC Macs but always worth a try:
- Unplug the unit from the mains.
- Remove the NVRAM battery
- Leave to stand for *at least* 2-3 hours
- Power up
The issue is the NVRAM (referred to as PRAM on a Mac just to be
contrary) becomes corrupt as the battery runs down. If the machine has
been stood unused for a long time it may have this aforementioned
amnesia.
I have, however, heard a lot of sorry tales of PowerMac G5s suffering
all manner of weird problems with PSUs, leaking liquid coolers and
more. It's worth thoroughly checking the whole system over before
proceeding.
