    Tried everything from archive and install (wouldn't read disk2 until the 9th try and ended up with 9 system folders). Then tried an Erase and Install. Still it refuses to boot. Get's hung up at the blue screen. Will only boot in safe mode. Now for the last few days even the startup chime is missing. Tried PRAM and NVRAM resets. no help. Won't boot from DiskWarrior boot disk either. Just hangs

    Now is a great time to invest in an Intel Mac... :rolleyes:
    Judging by the fact that you can still boot into safe mode, and OS reinstalls don't fix the problem, I would say that one of the semi-critical peripherals has failed and breaks the boot sequence. Sadly, this may require a replacement of the logic board.

    Yeah....OUCH. Someone mentioned bad capacitors. She tells me that they look swollen and cracked. Some she says, appear to be leaking. I'm unsure. I know that many are fixed in place and insulated by a wax. Others have said that the Video Card that was used in that model was not the best choice they could have made, and may be causing the problem.
    I'm Baffled. Gimme my PowerMac. I cobble together parts and HAL runs great. Using a DELL monitor right now. It was $5.00 at a garage sale. plugged it in and I'm back up. Hahahahaha

    Good News

    Damn I LOVE Apple:
    Turns out that Apple knew there was a problem with the motherboards on her model. They had a repair program that expired last year. She phoned Apple in California. Since we've owned and operated our own Print Shops for near 30 years and have purchased and "Registered" many Macs for our business, Apple had us on file and knew about us. Yes the repair program is over.
    BUT>>>>> In recognition of our many purchases and loyalty to Apple over the past 20+ years, starting with our Classic II, thru our Performa's, the iMacs and PowerMacs, They are going to refurb her iMac for Free. Bring everything up to factory new shape. She has an Appointment at the Apple Store in Jacksonville on Sunday at 1:30, AND a repair order number direct from Cupertino. Not just the Motherboard problem but they will replace anything that they find not up to factory spec.
    I guess after spending 10 thousand dollars plus, on Apple computers and periferals and software has payed off. Hahaha

    Had the same problem, but I figured it out...

    I had the same problem. I booted up in safe mode and clicked on accounts and went to startup items. I took out most everything. I then restarted and it worked. Turns out there was software not compatible with 10.5 in the start up items and it caused it to not boot.
