Monitors Shutting Off!!!I have dual monitors and 5 out of 10 times my PowerPC boots up fine and then 1 minute later, my monitors black-out. Computer is still on, but monitors just go black. They are ON just asleep or something.
A hard re-boot of the computer and then my monitors are fine EVERY time. Other times, they come on and stay on. No pattern whatsoever! I have the monitors on different power strips because I thought that might be an issue, but it still happens at random.
Thoughts?

Have you tried changing (if possible) the VGA or DVI cable between your monitor and the machine? Have you tried a different monitor to see if the problem is monitor specific?

Monitors Off!I have two different monitors hooked up with two different cables, so it can't be that. I'm thinking it might be my graphics card, but the confusing part is the reboot and how it fixes the problem every time. I just don't feel like spending the cash on a new card if it's something simple!

Have you checked your "Energy Saver" preference settings? Maybe your monitors are set to go to sleep after a very short time (1 minute, 5 minutes, etc.).
If so...just adjust the settings as necessary.

I thought about that too, but it doesn't account for the fact that when I start my computer for the first time my monitors go blank, but after a hard reboot they are working fine. If it was a setting issue or cable issue, then I would assume it would happen every time and the reboot wouldn't help? I'm at a loss here!

Just throwing out ideas but have you tried to plug in your monitors in to different outlets? Like one in one outlet and another in a different outlet.

I have them on different power strips altogether. Main monitor is on a battery back-up and secondary is on a simple power strip. Love the ideas, keep em coming!

check what you have in activity monitor before you shut down if possible, check you memory(*)

What PowerPC is this? Perhaps if it is say a G5 the gfx card needs to be re-seated.
Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Also are you or have you been gaming or using memory heavy programs (well it doesn't even need to be those, some times parallels or other programs leave things or aren't connecting properly.. check console for if anything is mentioned there)

OK, this is above my pay grade, but when I went to Console this is where everything seemed to go wrong (SEE BELOW) and that lower list that looks like 0X0000 etc. goes for another 30 lines.
My computer is a Mac Pro 2 x 3 GHz Dual-Core Intel Xeon. ATI Radeon X1900 XT 512 MB
No gaming.
However, I still can't understand why a reboot makes it work EVERY TIME. If my monitors stopped working I'd toss the card and replace it without a second thought, but the reboot confuses the hell out of me.

Just for the heck of it...try doing both an SMC and PRAM reset:
- SMC
- NVRAM and PRAM
