Freeze, reboot -- can't find startup disk!

Hi. Proud owner of a new iMac Core 2 Duo running 10.5.6 flawlessly for about three months.

Until yesterday.

Four times in 24 hours, when I jostle my Mac out of sleep mode, any open applications hang. I cannot force quit -- the finder hangs as well. So I have to power down and reboot. At which point I am greeted with a question-mark-in-a-folder icon at center screen, and the iMac will not startup. I resort to starting up with my Jaguar install disk, then try to run Disk First Aid -- but first aid cannot find my Mac to repair! It doesn't find it as a "Startup Disk," either. What gives?

The only way to fix things is to shut down (vs. restart) from the install disk, then let the computer sit idle for 30 seconds, then hit the power button and reboot. That seems to do the trick after a few tries.

Any ideas or solutions? This is ... annoying. Expensively annoying.

Thanks.

iMac 3.06 GHz Intel Core 2 Duo, Mac OS X (10.5.6)

rkaufmann,

I'm sorry, I misspoke (misptyped, whatever). I am using the Leopard disk my computer came with, not a Jaguar disk.

That said, I appreciate the link to the article. I will try resetting the PRAM, and also the tests re: the mouse. The mouse HAS been acting up lately, and I wonder if that's causing trouble ...

Thanks for the speedy reply.

well... i did face similar problems 2 years back.. but my mac is an ibook g4...

my screen freezes n when i reboot it, i saw a question mark within a folder... i can't boot it from other sources n i reckon it was my harddisk had crashed... i sent it to apple centre n the technicians can't boot it from my HD as well as via the disk... meaning i really have to change my hd... my applecare warranty was way over n i'm paying abt a hundred plus to get the hd replaced...

if u are still within the warranty period, get it fix... they usually wont charge u a single cent which i had once replacing my entire CD rom drive... give them a call n don't try rebooting...

as long as u see a question mark in a folder before startup, very high chance ur hd has crashed...

Well, I was being poetic, I guess. I just meant "when I wake the computer from sleep mode."

It doesn't happen every time, but ... maybe every fifth time I wake the iMac from sleep, all open applications hang (one by one) as well as the finder (which I discover when I try to force-quit anything).

I am forced to hard restart (hold power button in), and then, maybe every other time ... the folder / question mark icon. Sometime another hard restart does the trick. Sometimes it doesn't.

Starting up from the 10.5.6 disk my computer shipped with doesn't seem to help, as when I do (and then run "startup disk" or "disk first aid,") it often cannot find the iMac at all.

And yet ... if I shut down and reboot, all (every other time) is fine again.

Thoughts?

HI,

*"Starting up from the 10.5.6 disk my computer shipped with doesn't seem to help, as when I do (and then run "startup disk" or "disk first aid,") it often cannot find the iMac at all."*

That sounds like hard drive failure. If you can, now would be a good time to back up all important data to an external source just in case.

Sounds like it's time for service. This is a 3.06 iMac so it's fairly new? Under one year warranty?

This just happened to me a few days ago on my imac 24" that is one and a half years old (not under warranty). I know, I should have bought applecare. 🙂 But the HD was completely gone. They couldn't even retrieve my data.

I had to have a new HD put in. And now I am working away trying to get the computer back to the way I had it before the crash - Luckily I had time machine backing up my files on an external drive - but not my apps, so here I am installing updates and then all my programs back on, etc.

Good luck to you.... My advice is to take it right away to have it repaired or replaced. Mine crashed about 5 times over a period of 2 or 3 weeks before it completely went out. The first 4 times or so I was able to either start up while holding the option key and it would find the HD, or I would have to use the Installation disc 1 and have it run disk first aid and repair it - or so I thought.... If you take it in when it first starts behaving this way - they can possibly get your data and replace your drive before it is totally gone.

It is under warranty, and I've just booked some time with the Genius bar at my local Apple Store.

At this point, I just hope I can reboot one last time to finish backing up my music library (it keeps hanging mid-backup, dagnabbit!) before I turn the machine over to the pros (and run the risk of losing everything on the drive).

Thanks for your help. Wish me luck!
