I'm hoping someone can give me some advice. I've been all over the Internet looking for answers. Last night I was surfing the web and doing some CS3 work, when my Powermac G5 dual 2.0Ghz grayed out with a kernel panic. I restarted the system and none my apps would work longer than 2 min. After a couple more restarts, none of my apps would start. After another restart, I just got a hanging blue screen after login. I unhooked peripherals, and I thought it might be ram, so I tested out different configurations, but I still got the same error. I then thought it could be my hard drive failing (original 160gb). After trying disk utility and fsck -fy, the drive still didn't want to boot, so I purchased Disk Warrior. I threw in my old 80gb with OSX installed, and ran it through the DW rebuild/replace. I was able to view the files in the 160gb, so I backed it up. Even after this, I couldn't get my 160gb to start up...just the login screen, then blue screen. I also reset PRAM, but no go. Then the next time I tried to boot using my 80gb, the same thing happened --BSOD! Now I have two drives that don't boot, but I can verify these disks without issue in Disk Utility and run through Target Disk Mode, and DiskWarrior replace/rebuild. HOWEVER, when I tried to archive/install Tiger on the 80gb, it eventually times out and asks me to try again (3x's now). I even tried erase/install and it still doesn't work. I can boot using the Tiger install cd's, and through Target disk mode. I don't have the hardware/original disks that came with it. I haven't tried to reinstall on my main 160gb yet.....any thoughts before I do? I'm hoping I just have two bad HDD's instead of a more expensive hardware issue. Sorry for the long post, but thanks for any help!
