I've got nearly the same problem on my old dual G4, I let it sit for a few months and now I get the "Gray screen with the death spin cursor". It's kind of hard to back up data if you can't get to it
. I've tried booting from the Tiger install DVD, which worked well enough to install the os, but it still refuses to boot. I even installed it on a 2nd drive I had installed last year, still the cursor of death.
I checked the firmware revision, but it's current
. I let it spin all night after I brought it up, still nothing. I'm going to attempt to zap my prams tonight when I get home from work to see if that helps. I don't want to do an install that erases the disk because there's data and work I really don't want to lose.
If anyone knows how to get out of this, I'd appreciate the assistance,
Thanks
