Hello, Hopefully this is an easy one, but need some guidance... I have recently encountered the GSOD (w/ spinning wheel) and then the BSOD (which flashes between dark and light forever). Hopefully my set up will save me in the long run, here's what I have: A G5 desktop Power PC w/ two internal drives. I have one whole drive devoted as my back up which Time Machine performs regular hourly back ups to. Then my main hard drive is partitioned with an "eDrive" so I can boot up from it for times like this! I have booted from the eDrive and performed the basic litany of tests from TechTool and verified/repaired disk from Disk Utility -- all checks out ok (but, still doesn't boot) Also zapped PRAM and repaired permissions. I really suspected my Firefox to be the culprit since it wouldn't launch ("extra copy still open") right before the mac went down. So I deleted the invisible file ".parentlock" from its profile folder - but no dice, still won't start. My next thought is hey, I have regular backups! BUT I don't own a Leopard install disk! So-- HERE'S MY QUESTION: Is there a simple way to use my back up to restore the probable part of my system files/folders that may be causing the hang up? Or do I need to go buy a Leopard install disk so I can use it to go through the restore process. I do have a good mac restore shop, but I'm trying to avoid the probable 250.00 fee to fix this! Thanks for any help!
