imac won't start up

my imac won't start up. It gets to a screen that has a computer face (smiling) and a beach ball spinng. It won't go past this point. I have tried holding keys command+s at start up but nothing happened except lines of code on the screen. It would not accept typing more info. Any suggestions?

Hi Weed,
OS version is X (10.X?) I'm not sure. I'm not a mac guy. (The imac is my daughter's.) Just before the problem everything was OK. Nothing out of the ordinary, as far as I know. We don't have virus protection. Could it be a virus?

njxbean,
I can't get it to boot with any disk. I have tried all the ones I have. No good.

Should I reformat the hard drive. If so how?

There are no virii for OS X.

You cant even boot from the OS X installer disc?

try zapping the p-ram.  Hold apple + option + P +R while booting the computer.  Wait untill u hear 3 chimes then let go.  However, you should be able to boot with a cd.

rmontjoy,

To boot from your CD.

- Power On your computer, immidiately insert the CD, and press and hold C.  If you do it quick enough, it will boot from your CD-ROM.  Else, with the CD still inside, restart the Mac and press and hold C.

OR

- Press and hold OPTION key, and turn on your computer.  It will enter a special boot page.  Insert your boot CD.  Click on that CD and click the RIGHT ARROW on the lower right of the screen.

OSX has no virus... (at least for the moment). :)  I think you'll just need to do what njxbean suggestion (repair the disk and the permission).

Good Luck.

Good Morning,

I have tried all the above suggestions and nothing works.

Any more ideas? Is this a throw away?

What happens when you try to boot from the installer CD?

njxbeanCommented:
You should try to be a bit more descriptive as to what happens when it doesnt work.  So you cant boot with ANY cd?  what cd's are you trying to boot with?  Do you have another mac?  you can try booting it into target disk mode and then repairing the permissions that way.

Thanks for your replies,

It will not boot from any cd. I have tried the OSX cd, the os 9 cd, and one other one that came with the computer. None of them works.

Everything I have tried results in the same outcome-- a smiling computer face in the middle of the screen and a rotating "beachball" in the upper left corner of the screen.

The "optioon" key hold down during start up did produce a screen that gave me a chioce of booting fron the hard drive or a cd. I selected the cd option, with the OSX cd in the drvie but got the smiling computer screen--nothing after that.

When you boot with the os 9 cd, you see the computer and a "spinning beach ball"?   YOu might wanna try target disk mode at this point.

Hi njxbean,

Thanks for your reply.

I don't understand target disk mode. Please explain.

oh.  Sorry for not explaining it.  What you need to do is connect the imac to another mac using a firewire cable.  Then, boot the imac up while holding "T".  You should see a firewire sign on the screen of the imac.  Then, on the other macintosh, you should see the imac harddrive mount to the desktop.  Once that is mounted, you can try repairing permissions or running diskwarrior.  If need be, backup your data, then format and reinstall the os on that drive.

Rmonjoy,

Have you ever wait for how long does the 'rotating beachball' last?  For some mac, it will took a while to boot from CD (and I really mean a while like around 4-5 minutes or even more if you have a scratched CD, a dirty or old CD DRIVE, or a CD-R disc.  On one of my eMac (new), it refuses to boot from a CDR boot disk, but other eMac got no problem.).

Have you try to boot with Apple Hardware Test CD?  Use this CD to check your Mac hardware.

Hi Ray!

i had the same problem as well and twice it had happened to me! talk about bad luck! but luckily I was still on warrenty so I took it to the apple care centre and I was there for about half a day as i wanted to see what they do as well. The CD that comes with the Mac will do the trick. It will boot up but like what idarmadi said it takes very long. You will have to wait. Like what njxbean said...repair the permissions! Hope this helps!
