G5 wake up issues

2010-10-30 Thread DLC
Greetings all,
Just need a little direction.
One of the G5s in our music lab (1.8GHz/DP/June 2004 model) recently
went through a nuke-and-pave (as Bruce likes to say :-),
putting a new copy of OS 10.5.8 on it.
Since then it does not like to wake up if it falls asleep (kind of the
opposite of the more common doesn't go to sleep issue),
or perhaps more accurately, it *may* wake up but unsuccessfully fires
up the monitor. Only recourse is to do a hard shut down and a restart
in order to regain functionality.
I've reset the board with a battery/power cord pull, pressing the PMU
button waiting several minutes and reconnect; and I've zapped the PRAM/
NVRAM with no luck on either. I've not yet booted into single-user
mode, thinking that the OS is too new (its only visits on web are to
do the Software Updates), but will try that on Monday.

Beyond that, any other suggestions/ directions?

Thank you in advance for any thoughts.
Best regards,
Dana

Are there any PCI cards in it?  They can cause such a problem.  If there are 
such card(s), try removing them.
