Unable to boot

Hi all,

I've just got this problem recently.
My 24" Intel (mid 2008 model) iMac won't boot pass the apple logo and "spinning lines".

The built in Hardware test (ran an extended test) returns no errors, went into single user mode... performed fsck, rebooted, still no go.

Tried booting from Disc, it gave the screen, prompting to reboot, then same situation after a reboot.

Failed to enter safe mode.

Please help..

1 thing I've noticed the screen will sort of blink once after it hangs...usually like just a frame of red screen
 
Sounds as if the hard drive went operating system went south. Boot with the Leopard instal disk and do an Archive & install after you used Disk Utility (hidden in the menu items on the Leopard install disk). You then will get a Previous System folder you can get you private data from and then through the folder away when you are done get data out of it.

Hopefully this will work with loosing all your data.
 
Yes, jbarley is correct, already tried booting from the install disc. but no go ~, it's still hanging after what seems like the disc prompting to reboot the system
 
Any help would be greatly appreciated. Had tried Firewire disk mode to my Windows Lappy with a hfs explorer... would seems it's not a HDD issue, as I can "copy" the files out of the Mac to the laptop...

any1?? running out of options that I can find.
 
it's kind of random at the lines it stops while booting in verbose mode.

but generally I'm getting

Thanks in advance

Could either be a bad hard drive or optical drive or optical drive cable. I've seen all of those mentioned go bad on those causing those symptoms. Seeing as you were able to run the hardware test I would assume the optical drive and cable are fine. If you could see the drive through target disk mode on another Mac. Go to disk utility check the SMART status of the drive and run a repair disk on the drive and see what comes up. Plus as long as you can copy files off the machine, make sure you back up what you need.
