I get gray screen with flashing ? and a face... Have reset NVRAM PRAM.. Still won't boot... need help
PowerMac, Mac OS X (10.5.8), Power PC G5
Does anything show for a boot source if you hold Option or alt key at bootup?
Can you boot from your Install Disc?
Does anything show for a boot source if you hold Option or alt key at bootup?

I don't have a boot disc. When I boot holding down the shift key I get a gray screen with a little folder that alternates a flashing ? and a flashing profile face.
When I hold the option key I get a blue screen with a what appears to be a refresh
circular arrow and a separate option of an arrow pointing to the right of the screen. When I click on the circular
arrow a little clock starts but nothing ever happens. When I click the other arrow also nothing happens.
I rebooted with the option F O and followed the suggestion to reset-nvram and then reset-all.
before I did all that at open firmware page I received some weird error messages as follows:
invalid memory access @ SRR: 00000000 ff84601c SSR1: 10000000 0200b030
then
illegal instruction @ the following locations , all beginning with
SRR0: 00000000 ff8b6ffc
" 86d9b4
" " a4
846174
" 8497cO
" 84825c
" 86d9cc
and so on with mostly the 1st referenced ff8b6ffc
Did the mac-boot which brought me back to the gray screen ..with little flashing folder again
F O page reads at the top

Welcome to Open Firmware, and the system time ( ) and date
to continue booting, type" mac-boot" and press return
release keys to continue:
The Boot drive should show between the circle arrow & right arrow, so something is messed up big time, I'ds ay the HDD except for those errors.
If you're sure the RAM is good, try the Hair Dryer trick...

No power light at all...

It can show on any G5, and even many other computers & electronic devices of the period.

Well, I followed all your links and have been reading like a madman/gal... Did the hair dryer trick but maybe not long enough. Will try again but it got so friggin hot it scared me. Is there any commands I can do in Open Firmware to try and do some diagnostics or something? I am new to Apple/Mac. if this was a pc I'd have at least figured out something by now, but I am so intimidated by this monster I don't know what to do next! Any additional help would be so appreciated.... this much I know, and can't remember if I referenced...

Try Verbose mode...

CMD+v keys on bootup, watch for clues.
No luck for Verbose or single user mode? One thing I didn't mention and is a shot in the dark butttt
I just got a new smart phone and I recall it was after a "sync" that this happened, could it be related?
My smart phone when trying to connect via wireless does reference a Mac address, how did it know
I had a mac if a wireless connection wasn't set up?
Is there a mem test in O F? That I could try since my error messages are memory related
Grateful for all the help

Purely coincidence I think.
There's MAC Adresses & Mac addresses...

Not unless already installed.
Boot off your *original* Install Disk , then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.
The Memory test can really only be trusted if it finds a problem, not if it doesn't find a problem. 😟
Memtest OS X...

There may be other options that cannot be mentioned here, but if anybody had those clues they couldn't contact you because only you can see your eMail Addy in your Profile here. 😉
Any other suggestions appreciated, contact info updated in bio: Thx for the tip
