Jan 17, 2014 4:45 PM in response to Suzanna Pilatby BDAqua,Hi Suz,
Hold alt key at bootup, do you see any boot choices?
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).

Jan 17, 2014 6:26 PM in response to BDAquaby Suzanna Pilat,TKU for answering! I do not have an 'alt' key... Before my G5, I had a Sun machine. Never had a Windoz machine. Is the alt key the Apple command key?

Jan 17, 2014 6:58 PM in response to Suzanna Pilatby BDAqua,Sometimes it's called option key on a Mac, Apple or Command key, (CMD) is different key, no idea what it might be on a Sun KB.

Jan 18, 2014 10:52 AM in response to BDAquaby Suzanna Pilat,OK TKU! I will try just pushing the 'option' key and let you know.

Jan 18, 2014 1:17 PM in response to BDAquaby Suzanna Pilat,well 'option' did nothing - neither did safe boot. Other ideas? Seems it doesn't recognize my keyboard.

Jan 20, 2014 10:08 AM in response to Suzanna Pilatby Adam Simpson5,Hi Suzanna, there seems to be a bit of similarity with my G5 problems, except I had leopard. My keyboard has stopped working also. Have a read of my posts too, we may end up in a similar situation.

Jan 23, 2014 1:29 PM in response to Adam Simpson5by Suzanna Pilat,TKU Adam! Haven't had a chance yet to look at it. I put on new keyboard and mouse but did not help. I left it on and the fan started roaring.
-
Jan 23, 2014 1:35 PM in response to BDAquaby Suzanna Pilat,I thought I would try another keyboard and mouse as I had another working one near, but no go. Left it on a bit and fans started roaring again so shut down.

Jan 23, 2014 1:47 PM in response to Suzanna Pilatby BDAqua,The fans roaring are normal safety feature when no OS takes over control of the fans, that said no use leaving it like that, but not dangerous.
So, holding alt or option key at bootup shows no boot volumes?
Long shot, but...

No power light at all...

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

Jan 30, 2014 6:34 AM in response to BDAquaby Adam Simpson5,Hi, yes upon pressing the power button, there is like a big hum (kind of sounds like the fans going briefly, but it probably isn't that).
