My Powerbook froze, so I rebooted and now it fails to boot into OS X or at all for that matter. I hear the chime and see a gray screen and it just sits. Help! I have had so many problems with this powerbook, it boggles my mind. The hard drive has been replaced, the logic board has been replaced... I just dont understand. I thought macs were supposed to be reliable/not crash! I can't boot into single user mode or target disk mode. I just don't get it. I won't have access to Install discs until Friday, and even then I don't think it would even boot from a CD. Any ideas? Please? I'm desparate and frustrated and out of warranty. Thanks in advance.
Got a tip for us?

When your PB fails to start up, does it beep at you (apart from the startup chime)?
"Beep codes", if available, can be used to diagnose a Mac that won't boot. For example, I once had a similar problem with my iBook... and I was getting two beeps. A search on the Apple website translated this as meaning failed memory. I replaced the RAM and it worked fine.
Good luck

Pram reset or a PMU reset.

No beeps, other than the startup chime. And no luck with resetting the PMU or PRAM. Any other ideas?
