IMac not booting up... need help!!

Hey guys,
I got an update from apple yesterday for I believe it was a new update for quicktime, and after installing and rebooting I found that I had no control over the menubar and the dock, as I could not access anything the only thing I could think of doing is holding down the power button to restart. After doing this my iMac would not boot up past the initial apple logo boot screen and would just freeze at that, i've tried everything I could think of and have had no sucess.
If anyone can help me with some advice it would be much appreciated!
Many Thanks,
Richard Walker.
p.s. I have a broken superdrive and i am running the latest version of leopard.

I can assure you that the problem is with you not the update. Remember this is a place for Mac users to come to with issues. The vast majority of us install our updates without a problem, primarily because of how out machines are maintained. I can only suggest contacting an Apple repair centre to have your Superdrive replaced so you can reinstall OSX. Whatever you decide, when you finally get things back, invest in a 3rd party Disk Utility like DiskWarrior as it's an excellent tool. By running it regularly as part of a maintenance routine, when you come to run updates in future, you shouldn't find yourself here again as a result. Good Luck.

Early 08 iMac not booting - You Need to Restart Message

So after lunch today, I touched the shift key to wake up my iMac from sleeping. Screen came up, but it was totally frozen with distorted green digital "crud" in various places in the display. (no other way I know to describe the green stuff, it wasn't consistent lines or anything...just random distortion).
I powered down to restart, and the following message came up http://gallery.me.com/daveoli#100064 advising me I had to restart again. Did so, and same message. Tried the following methods, all resulting in the same message coming up:
Unplugged completed, waited an hour (in case of overheating) and powered-up.
Booted holding D key for h/w test - no test just got same message.
Booted in safe mode.
Booted from CD.
I called apple support, and the tech advised me to boot holding down cmd-option-r and then p to reset pram. 3 bongs, and then release....this worked! The mac booted up. First thing I did was connect firewire drive and make a back up. Ran a disk check with disk util and everything was ok. I then started to download the hw util from the mac site...and wham, screen froze again with the green crud.
This time, restarting with the resetting the pram did not work. Nothing gets me to progress beyond that "need to restart" screen. I will call Apple again in the morning...but in the mean time, any one here have any ideas or have seen this issue before?

That's a *kernel panic.*
They are usually caused by hardware problems, but can be software.
Disconnect all peripherals, except keyboard and mouse. Reconnect one at a time to see if you can find the culprit.
If that's no help, run the Apple Hardware Test, from the separate disc that came with your Mac.

HP Pavilion dv4 notepad not booting. NEED Help!!!

Hi There,
I have HP Pavilion DV4. For some odd reason, when I turn on my notepad, I just get one flash of power light, volume indicating light, num lock light, caps lock light, and screen stays blank. Notepad doesn't boot but power light keeps flashing.
Initially I thought maybe my battery was low, so I plugged in the AC adaptor overnight and in morning it behaved the same way. I have tried all solutions suggested in blogs all over (including removing AC adaptor and battery and hold down power button for a minute, etc.) I am still not able to get my notepad to turn on. I have even tried to have it plugged in for few days, but I get the same thing from it.
I would greatly appreciate it if someone could help me out with this issue.
Thanks.

Have you tried to start it with just the power adaptor connected and the battery removed? Have you disconnected all external devices that may be attached to the notebook?

DOES not boot! Need help please!

I just bought a k7t266 pro2-u and a amd xp2400+, new case and 400 watt psu. When I push the power button, nothing happens in the computer, no fans, no drives. I see power on the front light though, which is connected ot the motherboard. Any suggestions? I may have connected the power switch wrong or something, I'm really not sure, Thanks alot to anyone who can help.

Any joy yet? Make sure all your front panel switches are connected correctly. Uplug any USB connectors that connect to the front of your case (if you have them) these can cause all kinds of shorts.
Is your board mounted properly in the case and the HSF mount on your CPU?
You can only connect the main power to the board one way. Read the manual regarding the DLEDS

I restored my iphone and updated it but the progress didn't complete and now my iphone is not working. i need help asap.

my phone was not working only the restore button was available so i restored it and they told me i have to update my iphone 5s as well. i waited till the end the update software was downloaded successfully but then the iphone restarted by itself and now its not working. the iphone screen is shown the picture when you first time open the phone to connect it to an itunes. i connected it by it not working, i restart everything still not working:( i need help asap please. thankyou

it seems like apple's activation servers have gone down under the weight of the overwhelming amount of activation requests. you will be able to activate your phone once the servers are able to catch up with the activation requests.

Not booting up/Need reset SMC/"Service battery" sign.. culprit ?

Trying to figure out if "Service Battery" is the cause of sometimes the comp not booting up (needing to do SMC reset) even though battery metter shows it charged ?

Battery Health and battery charge are different things. You can have a battery with 50% health and 100% charge, but the 100% charge is 50% of the battery's original capacity.
It is very unlikely that the bootup problem has anything to do with the battery.

27" iMac not booting after start up. HELP!

After being turned off for 8 hours, iMac won't boot up fully. After being stuck on white screen with apple logo and spinning loading icon for 20 mins, I held the power buttom down but still nothing.
Can anyone suggest steps to take?
Cheers
Sam

Hi Sam,
I agree with baltwo, If your Macintosh is behaving erratically or is not booting up all the way, you may want to try resetting the PRAM as per below;
1) Shut down the computer.
2) Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3) Turn on the computer.
4) Press and hold the Command-Option-P-R keys. You must press this key combination before the grey screen appears.
5) Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6) Release the keys.
This resets the PRAM
PRAM is a type of memory found in Macintosh computers that stores system settings. These settings include display settings (like screen resolution and color depth), the time zone setting, speaker volume, and the startup volume choice. The system settings that are stored in the computer's PRAM differ from Mac to Mac, but the purpose of the memory remains the same.

Got stuck at boot. Need help.

Guys, I need your help.
I have created a Bootcamp partition and wanted to install windows. I guess the disk is corrupted so when the computer restarted I got stuck with a black window, the iMac will not boot from the DVD. The problem is that I cannot switch back to my Leopard partition and the DVD is stuck into the superdrive (I cannot eject it). If I restart the computer it eventually goes to the same black screen. What can I do? I have a Logitech keyboard so the "Option" button is not recognized at startup to switch to Leopard. Any idea?
Thanks.
Andrew

Oh.... try to hold the "S" key for safe start-up....???

Help! Computer turns on but then will not boot up - Please Help!

I have no idea what happened to my Apple. Someone please help me. My powerbook currently is running on no battery (recall victim) and now the entire computer is no longer functioning at all. I installed iTunes 7.0 and then the trouble began. I had to restart the computer, so I did that and then the computer just wont boot up. It goes to the grey screen which shows the Apple symbol and occurs right before my log in then just continues to read. The green light for the battery is function and nothing at all is working. The computer simply will not boot up, I have tried unplugging it for the night and then rebooting it and nothing. Please someone help, what has went wrong?

You mentioned in your other thread that you had trouble with a cpu(0) hardware error trying to use the hardware test disk. Is this the hardware test disk which came with that particular machine? If not, then you need to find the original hardware test disk that came with that machine. If the restore disks that say 12" Powerbook include the words hardware test, use those instead and follow these directions:
http://docs.info.apple.com/article.html?artnum=86287
If you are using the correct hardware test disk and you get a cpu(0) error using it, then the machine has a hardware problem.

IMac not booting from HD, cannot repair disc in Disk Utility

First the problem:
I've had the imac G5 for nearly two years and its been running without a problem, now it suddenly wouldn't start up. Firstly I get two or three grey screens in succession looking as if being drawn from top to bottom very quickly, then the apple logo and timer, after a minute or so the fans start up to full power and it stays that way.
What I've tried:
Reading around discussions I tried rebooting from DVD installer and using disk utility. Result: error message: The underlying task reported failure on exit. 1 volume could not be repaired because of an error.
Because I want to sell the imac I had backed up all of my important data so I zero-wrote the hard drive in preferrence to buying a third party repair package. Reinstalled from DVD. Shut down and restarted. Everything worked except those banding grey screens appeared that were never there before. Something looks wrong. Then when i tried to reinstall microsoft office (as a test) the OS seemed to freeze and I had to shut it down again. Now it won't boot up as before. This looks like a very serious problem.
I hesitate to buy tech tool pro in case that doesn't solve it either.
Can't think if I did something to cause this. All I've been doing is transferring some data via ethernet to a newer mac. There was also a Lacie firewire drive linked to both computers as i was backing up stuff. One night I shut the iMac down and the next day it started with this problem.
Well... any educated suggestions would be most welcome,
thanks.
By the way, the memory in the mac was purchsed from a third party and installed ages ago by myself. Never been a problem with it and have been running Final Cut Studio no trouble.
iMac G5 2GHz Mac OS X (10.4.7) RAM 2GB

Long story short, I had the same problem last week, just after installing the latest software updates. I went through all the resets and disk utility verification (multiple times with phone support -- Apple Care), then took it to the local Apple store b/c nothing worked. They couldn't figure it out either and recommended that I try to backup my data on my bootable external drive before they started messing with my hard drive, since Apple stopped providing this service. I brought it home, could not boot from my external drive, so booted from the disk again, just for kicks I ran the same verification process (this was the 3rd or 4th time). This time something happened but it still failed. So I ran it three more times (each time something new happened and then it failed, until the third time when everything worked. The only problem now is that I seem to have lost all sound???? I did immediately make a duplicate of the Imac hard drive. Any thoughts on how to get my sound back? hope this helps....
Imac G5 20" Mac OS X (10.4.9)

Imac not booting, Able to get to disk ulility with snow leopard disk. Tap on had disk, not given choice to do anything. Information list that smart is certified and partition map is us formatted. How do I get mac to start up again?

Imac not starting up, keep getting white screen. Using snow leopard. Able to get to disk utilities with snow leopard installation disk. Tap on had disk, not given choice to certified disk or anything else. Information on disk states that smart status is certified. Partition map I formatted. Also tried to restore from back up, but get error: not enough disk space. Tried to erase disk, but unable. What do I do next to get mac to start up?

Thank you. That's what I thought will need to happen.
One more question. I tried using the Apple install disk that came with the computer. It's an OS 10.5.6 disk. It does not see my 10.6.8 system internal hard drive to repair. All it see's is itself 10.5.6 disk. Do you think I can use a 10.8+ disk utillity since that is a higher system it will see the 10.6.8. Where the 10.5.6 does not?
I don't want to turn the computer off for fear I'll get the question mark again. P-Ram got me going last time but for how long I don't know? It would be nice to be able to turn the computer off for the night and startup as usual to give it a rest and try to reset itself.
Thanks for your help, I know I will eventually need to re-install. But I am in the middle of a project with tight deadlines and all I can do right now is back-up. Trying to migrate to another computer temporarily to finish the job. That's a lot of extra work in the short time also.
Just trying to put a band-aid on it for another couple weeks.

Imac Not Booting From CD

I've tried just about everything at this stage, so I'm here asking for help. I have an Imac, of which I can log into the root account and has no openfirmware password. The Macos ISO is seen from within Macosx, though I cannot get it to boot from cd, whether holding down the "c" key or setting that device to boot up first from the startup disk menu. I have tried resetting the pram and nvram and reset-all within openfirmware, and the "boot-device" command within openfirmware shows exactly the same as another machine which does boot from cd. I know that both the drive and (multiple) CD's I've tried are functional.
Can anyone point me in the right direction as I am at a loss at the moment and have no further idea's of my own.

n0der,Welcome to Apple Discussions.
Is the Optical drive known good? can you read other disks?
If not do you have another Mac you could use Target Disk Mode on and hence use that Mac's optical drive rather than the iMac's internal...
Does Apple Hardware Test CD report any faults or will it not boot from that either?
