My iMac 24" inte will not boot. Monitor lights up with squiggly little lines, but that's all. Help??

Can you run Apple Hardware Test. In you case it is not so much to see what it finds but to see whether you can boot it at all.
Or try a safe boot.
It may be time to take to apple for repair.

I have tried resetting PRAM and all other items listed in the Apple support site. This happened after an update to iTunes was added. Also this is happening to other people. Please help.

IMAC 21.5 " allinone will not boot after OS re-installed

Had to erase HD and re-install Snow Leopard from installation disc. It completed OK but sys will not boot, tone sounds and Apple logo comes up and 'wheel' is spinning, but that's it. Waited for over half hour before shutting down. Thanks for any help anyone can provide.

Try a safe boot by holding the Shift key down between the startup tone and logo.
If succesful, go to System Preferences > Startup disk > select your HD and restart.

Imac intel circa 2005 will not boot

I was woundering if anybody might point me in the direction of resolution to this problem. My intel circa 2005 iMac will not boot - OS Tiger - get a blue screen. Funny thing is that when I reinstall OS the computer works alright for a day or two then crashes when I open a programme such as iPhoto. I then reboot and get the blue screen of death again. I have done this several times. The reinstall works again only for a day or two then back to square one. I have clean installed reformated the hard drive etc all the resets etc. I have also run the hardware test extended and this said all was ok. Ran disk utility and seemed to write 'zero' alright on the whole disk. My gut feeling is the hard drive is on the way out but the ability to write zeros to the whole disk has stopped me from replacing this. Has anybody experienced this before and found a fix without buying a new iMac?

IMac modell 8.1. will not boot, screen issues

Hi!
My iMac 24" modell 8.1. (IC2D - 2,8 GHz) will not boot from install disc OS X 10.6. When I turn the machin on I hear the sound ok, then the grey screen appear with the black apple logo and the spinning wheel starts up. Then nothing happens. I hear that the superdrive is spinning up with the install disc, but nothing happens on the screen.
The screen has much flickering/distortion, so I removed the LCD display and checked all the three cables between screen and logic board to see that they are secured.
I have installed an 2 TB HD in this iMac formatted in Mac OS X extended journaled. The 4 LED lights on the bottom of the logic board are on and green. Remember back with my PM G5 that I had to push a cuda button, is there any such button on this iMac?
Any suggestions?

No, you want to run DU from whatever version is on the boot volume. The original version it shipped with was 10.5, but if it's now 10.6, he wants to use a 10.6 disc to repair with.
For the video symptoms, I would run the Hardware Test, in extended from the 10.5 disc, if it will boot to that.
http://support.apple.com/kb/ht1509
And Roam's suggestion to try a Safe Boot is a must.
EDIT: Permissions Repair should be done -- and I don't think this is appropriate to do now, anyway -- from the normal boot volume, not from the DVD. And, certainly not from the original disc.

MacBook Pro will not boot up, stops at Apple logo

My daughter's 3 year old MacBook Pro will not boot up. The grey screen with Apple logo comes up and it looks and sounds like it is going to boot up but after 30 seconds it goes black and turns off. Any ideas or suggestions would be appreciated.

The internal HDD will have to be replaced. Since you cannot get the MBP to acces the internal HDD, you will have either use Target Disk Mode:
http://support.apple.com/kb/HT1661
Or take out the HDD and place it in an enclosure and then connect it to the MBP via USB. (After you have installed the new HDD and the OSX)
You may or may not be able to get information off of the HDD.
Ciao.

Laptop will not boot, no display and flashing caps key

Hi,
I am attemping to repair a laptop for a family member, their baby threw up on the keyboard, although after they cleared it up they said it was still working (booting into windows, mouse working etc). They took the old keyboard out themselves but it looks like they were a bit heavy handed with it; there are quite a few scratches on the metal plate underneath the keyboard and the plastic surround. I have not yet been able to confirm if the laptop was still booting after the keboard was removed.
Anyway - I went to their house to do what I thought was going to be a relatively easy job, simply connecting the new keyboard. Now the laptop will not boot, there is no display on the screen and we get a flashing CAPS/F12 key. I have looked at the table for LED codes, but I am not sure if it is one flash lots of times, or six flashes. The warranty has also run out so sending to HP not really an option.
There are six short flashes, with quite a long pause between each one. After this the laptop powers off and after another pause turns itself back on and starts over. If it is one flash (CPU) then I guess they must have shafted something on the board by shoving the screwdriver in underneath the keyboard to prise it away from the laptop. There is however not an awful lot of stuff exposed - there is a fairly substancial metal plate under where the keyboard would sit to protect the laptop.
I am hoping at the moment that it is showing six flashes - which is BIOS authentication error. I am not that familiar with HP products, but could this be caused by installing a non-genuine keyboard? The keyboard looks the same from the top, but was bought for less than a tenner on ebay.
If anybody has any ideas that would be great.
Aaron

Help! iMac G3 Indigo crt will not boot

Hello,
I'm an A+ PC technician and I'm trying to get an G3 iMac Indigo back up and running for a friend. I own a G4 Mac Pro so I'm somewhat familiar with Mac hardware and OSX and System 9.
Here's what I've done so far to get this little machine going again and it symptoms presented when I received it:
1. The system when powered up would chime once and boot to a smiley Mac then do nothing else.
2. When alternately booting using the option key to get to the drive option screen it would only show the HD and no CDROM drive. No other key combination would change this (CMD-OPT-P-R zapping the PROM) or booting into Open Firmware and reset-all.
3. I purchased a retail copy of System 9.0.4 that is bootable (I checked it in my G4 system) and held down the "C" key to boot from the CDROM-No go-as well as the Option key-no CDROM displayed.
4. I removed the HD, changed the jumper to slave and installed the HD in my G4 Mac and checked the drive integrity via OSX Hard Drive utility and the HD was repaired. The HD had a version of System 9 installed. Once the HD was reinstalled the G3 would still not boot.
5. I again removed the HD and again installed the disk as slave in my G4. I did a clean install of System 9.0.4 to the drive and removed the drive from the G4 and reinstalled the disk into the G3. Still no boot and now the G3 iMac displays the dreaded flashing ? mark folder after booting. The Option key also shows no drives attached now. No HD or CD.
6. I purchased a used replacement CDROM drive and installed it in the system-still no boot, no drives attached, nothing changed via zapping the PROM.
7. I changed the jumper settings in the G3 to master for the CDROM drive on the new CDROM and Slave for the HD. Still no boot,no drives displayed, zapping the PROM-no change.
8. Today I changed the PROM battery by exchanging the PROM batteries from my G4 system to the G3 and there was still no change. The old battery from the G3 is fine since my G4 system rebooted with it installed. I have also reset the PMU switch after the battery install.
I've probably done more harm to this system than was necessary by my trouble shooting actions. The HD was probably bootable before I did the clean reformat and install of System 9.0.4. but I'm not certain.
Tell me if I've overlooked something or done something wrong along the line.
Thank you for any assistance this community can give.

seeing the smiley Mac means that you have a classic version of Mac OS installed on the hard drive.
2. When alternately booting using the option key to get to the drive option screen it would only show the HD and no CDROM drive. No other key combination would change this (CMD-OPT-P-R zapping the PROM) or booting into Open Firmware and reset-all.
you need to have a bootable CD in the drive for you to see the CD in a drive. Mac OS X works with media not devices.
I have a bootable System 9.0.4 CD.
only show the HD
So, Mac OS is showing a bootable partition, not a hard drive.
3. I purchased a retail copy of System 9.0.4 that is bootable (I checked it in my G4 system) and held down the "C" key to boot from the CDROM-No go-as well as the Option key-no CDROM displayed.
See Richard's second paragraph having to boot up from the original cd to get cd reader to work again.
http://discussions.apple.com/thread.jspa?messageID=5966197#5966197
I'll try disconnecting the HD and leaving the CD drive connected to see if this works however it should be set as master on the cable.
4. I removed the HD, changed the jumper to slave and installed the HD in my G4 Mac and checked the drive integrity via OSX Hard Drive utility and the HD was repaired. The HD had a version of System 9 installed. Once the HD was reinstalled the G3 would still not boot.
Did you set the harddrive to master? Master is a must. Cable select doesn't work. You need to set the hard drive to master mode. There is usually a label on the hard drive that tells you what jumpers you need to set. If you are not sure, give us the name and model number of the hard drive and usually someone will be able to tell you how to set that drive.
Did you check all of the cables? Put everything back and verify that all works.
The HD is set to Master and the CD is set to slave with the correct jumper settings and the cable is attached.
5. I again removed the HD and again installed the disk as slave in my G4. I did a clean install of System 9.0.4 to the drive and removed the drive from the G4 and reinstalled the disk into the G3. Still no boot and now the G3 iMac displays the dreaded flashing ? mark folder after booting. The Option key also shows no drives attached now. No HD or CD.
I suggest that you reformat the drive then re-installed your software.
When I did the clean install of MacOS 9 it was after a reformat and reinstall of the OS.
6. I purchased a used replacement CDROM drive and installed it in the system-still no boot, no drives attached, nothing changed via zapping the PROM.
7. I changed the jumper settings in the G3 to master for the CDROM drive on the new CDROM and Slave for the HD. Still no boot,no drives displayed, zapping the PROM-no change.
8. Today I changed the PROM battery by exchanging the PROM batteries from my G4 system to the G3 and there was still no change. The old battery from the G3 is fine since my G4 system rebooted with it installed. I have also reset the PMU switch after the battery install.

Do you have firewire? You can use target disk mode. Some people have claimed success when installing through target disk mode. Use your g4 to load the software onto the target disk.
Firewire is not an option with this G3 iMac. The Indigo G3 doesn't have Firewire installed.

My iMac 10.5.8 will not boot or restart, until I power off and on

My iMac will not start up when shut down, or awake from sleep.
To get it to start i must turn off the power, and turn it back on, then it starts up and runs fine.
If i Restart it, it switches off, and will not power back on. The machine still works great but is begining to be a pain in the back-side cycling the power every morning.
I have done an SMC Reset, and that did not change it.
I have also added a new user, and when i logged in as the new user, it did restart a couple of times (cannot remember the exact amount) and then when i switched back to my normal account it restarted fine... i assumed it was fixed... but after that it's gone back to it's old painful self..
Any help would be appreciated, thanks
BG.

I just installed snow leopard yesterday through a disk I brought from apple., I had to keep the mouse moving during installation because every time it started sleeping I would need to cycle power which then restarted install!
I don't think the install fixed it because updating to 10.6.8 required a restart, and it wouldn't restart again. Painful.
The machine runs fine while it's running, never crashes, performance is fine. It is my work one so I won't be on it again till monday. I will try the repair advice then. I just accidentally selected that it solve my problem (on my iPhone trying to scroll up!!) please ignore that

IMac DV G3 400MHz will not boot with OS8.6 or 9.2.2 CD-ROMs

Here is the situation: I have burned copies of the install disks for OS 8.6 and OS 9.2.2 that I wish to install onto our iMac DV. I insert them into the computer while running OS X and it reads it correctly. However, when I attempt to boot from the CD, it skips it and starts booting from the hard drive.
When I am in OS X, I check the Startup Disk preference, and I set it to the CD-ROM, which it detects as containing a system folder. Then when I reboot, it continues to skip the CD and go right to the hard drive.
When the hard drive is formatted and does not contain an OS, and it only has the CD-ROM inside, it gives the Missing System Folder icon upon boot.
The machine has Firmware 4.1.9 and works well in OS X. It is currently formatted with five partitions on a 10GB hard drive, all formatted as Mac OS Extended. All partitions have the OS 9 drivers within. It has a 400MHz G3 with 256MB RAM.
Any thoughts?

While I am working on acquiring a pressed version of OS 9.0 and OS 8.6, I have additional information for you: I am able to boot and install from burned media for OS 10.2, 10.3 and 10.4 on this machine (which is an Orange iMac DV per the above note about the SE version). This tells me the machine can boot from burned media, but not into those OSes.
Another interesting fact: on a hunch, I copied the System Folder from the OS 9 install disk to the root of one of the hard drive's partitions, and then switched the Startup preference to that folder and tried it. It booted far enough into OS 9 to give me a happy Mac icon, then show the Mac OS 9.0 logo, but then popped up a message saying that the media was only able to boot from a removable drive, and that I would have to restart. Predictable, to be sure, but it shows the machine is at least capable of booting to OS9 somehow...

Imac freezese an now will not boot up

I have a 24in imac late 2006 which has recently been difficult to wake up with screen pixilation etc. Now it just freezes as soon as you touch anything and I cannot even get it to boot up now. Have reset smc and pram and now just have a blank screen. Have read how there is a problem with video card over heating but think it might even be more than that. Have applecare thank goodness.

I had the same thing happen to my 2006 24" iMac - the screen image had a strange grid pattern covering it, and I couldn't get past the grey apple loading screen before what looked like a kernel panic.
I took the mac in for repair at my local Apple-Authorised place, and it turned out to be a defective graphics card causing the problem. It was replaced, and now things seem to be running fine once more.
I suggest getting your mac checked out :o)
