WONT START AT ALL

Dear all, this is frustrating. The system just wont start up, chimes and spins around but just goes up to the apple logo and that is it. I leftit in sleep mode all night by mistake and the following day refused to start. Any ideas pls? I've done all the suggestions to reset the pram/ram.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

Itunes Wont Start At All No Error Messages Nothing HELP ME!!!!!!!!!!!!!!!

My Itunes Wont Work At All No Error Message Comes Up NOTHING ive Uninstalled , Deleted the Files in c Drive and Re Installed it Over and Over Again Quicktime Works Fine But When i Open Quicktime My Itunes is on there :S its very Confusing But i still cant Sync music Onto my Ipod or Buy Any Music Please Help Me!!!!!!!

Does iTunes.exe persist in the task manager or disappear again quickly. This can be a clue to the cause of the problem.
If iTunes persists this points to either firewall blocking or a damaged configuration file.
Try briefly turning off your firewall to see if iTunes will launch. Otherwise the link I will give at the end tells you how to delete the configuration file.
If iTunes doesn't appear or appears briefly and then disappears this may be a digital signing issue, also dealt with in the link.
It is a good idea to scan your PC for viruses and spyware, as malware can cause problems.

If the things I suggested above don't wiork, try working through the whole article.
All this is on the assumption that your Quicktime is working normally. I am a bit worried that you have been installing and uninstalling different versions, it just complicates the issue.

Imac G5 wont start up all the way

Hi i have an Imac G5 iSight and recently it would not start up properly. After a day or two without usage it became very slow and laggy when i tried to reuse it, so then i just manually shut it off. i then rebooted it and a flashing folder appeared (this isnt the first time ive seen the folder) then i just shut it off and let it sit there for about a day, after that i turned it on and it would send me to the greyish screen as usual with the apple logo on it with a loading bar at the bottom this time. the loading bar would barely fill up and then if would just shut itself off. Could anybody please help me with my situation?
P.S. - i tried holding the comm+opt+pr thing as well as holding the C button down when booting up. its also running Snow Leopard

First, if you're running Snow Leopard, you ave an Intel-based iMac, and not a PPC based G5 iSight iMac. The late 2006 iMacs look similar to the iSight iMacs.
Here are some items to try:
Run Disk Utility to Repair the Hard Drive and Repair Disk Permissions
Place your original, came with the iMac when purchased install disk, into the optical drive slot on the iMac. Restart the computer. Immediately press and hold the C key. (If you have upgraded your OS from when you purchased your iMac, example your iMac came with OS 10.3 installed, and you're now using OS 10.5, then use the OS 10.5 Retail Install disk that you had used to upgrade your OS instead of the original, came with the iMac disk.)
Release the C key when the spinning gear below the dark gray Apple logo appears. Wait for the installer to finish loading. DO NOT do an OS installation. After the installer loads select your language and click on the Continue button. When the menu bar appears at the top screen, click on Utilities, and pull down to select Disk Utility. On the left side of the window that opens, select your normal hard drive entry (manufacturer's ID and drive size). In the lower portion of the Disk Utility window you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say Verified, then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.)
If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid at the top middle of the window if it isn't already selected. Now click the Repair Disk button from the lower right area of the window. If the disk utility reports any errors that have been fixed, then re-run Repair Disk again, until no errors are reported. When that is done, click the Repair Permissions button to the left of the Repair Disk button you clicked earlier.
When that is done, quit Disk Utility.
If Disk Utility reports errors it cannot fix, then you will need DiskWarrior and/or Tech Tool Pro to repair the drive. These are third-party disk repair utilities that cost money. If you don't have them, Google them for more info. If neither of them can fix the drive, you will need to backup your data ASAP.
If that doesn't work, try resetting the System Management Controller (SMC)
1) Shutdown the computer.
2) Unplug all cables from the back of the computer, including the power cable.
3) Wait fifteen seconds.
4) Attach the computer's power cord.
5) Wait five seconds, then press the power button to turn on the computer.
Reset the PRAM or NVRAM
Reset your PRAM. Press and hold down the Command Option P R keys while starting your computer. You will hear the startup chime. continue holding down those keys until you hear the startup chime a second time. Release the keys. If the computer restarts, you will need to reset your Date and Time. It might be time to replace your PRAM battery.
Run the Apple Hardware Test (AHT)
See here for running AHT for Intel-based iMacs:
https://support.apple.com/kb/ht1509
Good luck.

Dv9000 turns on and off intermittently, wont start at all

Ok, today out of nowhere, everything on the screen of my pavillion dv9000 went screwy (repeated lines diagonally across the whole thing). Nothing was responding, or at least i couldnt see it responding, so i held the power button down to force shut it down. After that, whenever i tried to turn it back on, the lights, fan, and cd drive (or something else, sorry im not sure what it would be) came back on for a couple seconds, and then everything turned back off. Nothing come on the screen, not even the backlight. It then repeated this same thing every few seconds, even if i held down the power button, so i took the battery out to make it stop. One time it started booting up again (i did nothing different), but it only got past the first loading screen and then was blank for several minutes. I took the battery out, let it sit for half an hour, and i tried again. It still did the same thing but now the time that the lights, fan, drive are on is only about half a second. I've had the laptop for about 2 years and it has worked almost perfectly until today. Please help?

I placed this post in another thread, but it sounds like you have a damaged GPU.
I had this problem, but I have fixed it now. Fix below.
I have FIXED my misbehaving PC, and it is running better than ever!
I had the common problem that the GPU had overheated and had become unsoldered from the motherboard.
Here is how to fix it without spending hundreds of pounds/dollars!
Equipment/skills required...
*Small flat head electrical screwdriver
*Small Heat gun or jet lighter
*basic assembly knowledge of your laptop.
*know what a GPU is.
Firstly, strip the pc down to it's basic components, IE. screen, keyboard...
remove the motherboard and unscrew the heatsink from the board, leavint the CPU and GPU
exposed.
Remove the CPU from it's mount to prevent damage to it in the next step.
Surround the GPU with kitchen foil, making sure not to cover it. (the foil dissipates heat and protects
the surrounding components)
now use a chef's style heat gun or jet lighter to heat up the GPU evenly, moving the flame in small circles, heating it up evenly. Spend about five minutes on this. (there is a covering of wax on the processor, don't worry about that...)
Remove the foil, but DO NOT throw it away! Fold a part of it up so it is approximately the same length and width as the chip on the GPU, but a little thicker. Put this folded foil onto the GPU to hold it there firmly when you put the heatsink back on. Place the heat sink and fan assembly back on the motherboard. If you cannot feel or see a pressure over the graphics processor unit, make the foil block a little thicker. make sure the foil is not touching any of the little capacitors or solder balls on the GPU. (you want to get lots of pressure with the foil. This will stop the graphics processor from coming loose again.
Put the entire pc back together and try it.
It worked well for me!
Here's a link to the entire thread.

Itunes 9.1 wont start, says itunes has stopped working

I have a windows vista home premium 32 bit gateway laptop/pc, with a wired connection for internet. I have had no trouble for 3 years with past itunes but now with 9.0 and 9.1 it simply just wont start at all. When I double click on itunes I get, "itunes has stopped working and windows will notify you if a solution is avaible". I have tried to talk to numerous apple specialists but no can do because for them to troubleshoot with you, one has to own an apple product like ipod with serial number for them to actually help. I got rid of my ipod a long time ago, so I guess the option of talking to a non-robotic person will not work for some reason. A specialist gave me over 10 articles as to why itunes wont start with windows vista, things such as msconfig (changing startup options), uninstalling and reinstalling, having latest updates for firewall, itunes, among others which I already possess, Opening itunes on another user account and other too. I've tried all of these options and the only thing that I gained from all of these articles was I can open itunes on my different user account but when I do, it does not have any of my music on it. I have uninstalled itunes and reinstalled it before and the music has automatically showed up in itunes, but in the user account it does not do this. Does anyone know what the problem could be, it shouldn't be that hard for apple to provide a specialist to sit down after 30 minutes of eating there creme filled donuts and actually provide some customer service for the first time in history. Rhapsody has sat down for 2 and half hours and fixed my problem many times, (there based in the middle east and I can hardly understand them yet they were way more effient than itunes was). All I want is my precious metal music back which I poured over 100 dollars into. Thank you for everybodies support in trying to help me and others with same topic.

+I have checked in task manager and the programs itunes.exe and ituneshelper.exe are in the processes window but the program is not visible on the desktop.+
that usually means your security software is blocking it. Norton, McAfee, or whatever you use - try temporarily shutting it off and see if itunes will fully launch.

My mac wont start up. please help

hi, i wanted to reinstall osx panter as my computer was running really slow. I put the disc in ad my mac restarted. It now wont start upat all. i've tried holding down shfit and c abd still nothing happns.I can not get the disc out as i have a mac mini and the eject button on the key board isnt working. Do you know what ii can do? When I press the power butten the apple logo comes up as normal but then nothing happens

To eject the CD, depress the mouse button at startup.
To boot from a CD, you depress/hold the "c" key at startup.

all the leds light up and thats all that happends
is there somebody who can tell me what's wrong?

Are you using the original Power Adapter? If you don't use a 4 amp +5 VDC Power Adapter to power the amplifier, this is exactly the response you will get. If that isn't it, then you have a problem with the Amplifier, would be my guess.
Good Luck!

I t just wont start...

My mac mini wont start at all.
When I power up, all I get is a grey screen with a
small finder icon in the middle of the screen that
flashes into a question mark.......what's up with that?
Maybe to make matters worse, I inserted the "Intall/recovery disk"
but nothing happens.
To recap.
Flashing icon on a grey screen.
power off has to be done manually.
install disk is stuck inside
HELP ME PLEASE

That screen with the arrow in a circular shape and right-pointing arrow is the boot loader screen. Any valid MacOS volumes will appear there. The watch symbol typically spins for a few minutes as the system searches all possible locations, but if it shows no internal drive then either the drive has failed or corrupted, or MacOS on it is damaged. If you have inserted the correct install disk for that system and it doesn't show in that screen, then the install disk may be faulty, the optical drive may have failed, or the interface for the drives may have failed.
In the event of a hardware failure, it's worth trying a PMU reset (G4 minis) or an SMC reset (Intel systems). Don't use the wrong one of these procedures.
To reset the PMU (G4 minis - 2 USB ports on the rear)
-Unplug all cables from the computer, including the power cord.
-Wait 10 seconds.
-Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
-Let go of the power button.
-Press the power button once more to start up your Mac mini.
To reset the SMC on an Intel mini (4 USB ports on the rear):
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
If that doesn't help, make sure the install disk is the right one for the system - eject it by holding the left mouse button down during power up, and check it is the correct one for your mini - installers from other models will not work.

Xserve Raid #A1009 wont start :(

Hello everyone,
I just got in my possession an Xserve RAID Model#A1009 7.6/3.8A. Now since I got it I start to learn about this storage server, any way I connected to power then I connected to internet to access it remotely, I reformat the RAID partition on all 7 HDD which it came with and went fine no problem. On the logs I seen that "power supply 1 failed" error log, and the xserve work fine, but now after I reboot the Xserve for some reason wont start at all, all led from back of it are green and those from front of it only 2 led are green the controller status light ones. Please someone help me with this. Thank you.

+im lead to believe that i can put any old ATA/IDE drived up to 750GB as long as i run the latest firmware is that correct?+
When 750 PATAs were plentiful peoples results were mixed. The simple version is if the RAID understands the SMART controller the drive would work. Mostly there were a few 750GB models "known good" so everyone went with those until they stopped making them. I have to disagree with the "any old" characterization. It's not as picky as the Xserves but certain models *do not* work. Search the old threads about people trying trying different drives with mixed results. As I said the Caviar 500GB are the only drives still being made that I know of to reported as "known working".
On the larger issue I would very much hesitate to mix and match any drives in a RAID set-up due to reliability issues between drives. Whatever drives you settle on I would get them all the same models new at the same time.
I like my Xserve RAID - the thing is a workhorse - but I'd look at the cost + the cost of 16 replacement drives and look at what you might get in a SATA housing since those drives are still current.

Hi KB
that is indeed the whole report - & the pertinent line is, as ~Bee said
image not found /System/Library/Frameworks/Security.framework/Security
What this means is - Safari tries to load another piece of software, and can't - either because it's missing or damaged somehow.
you didn't attempt to remove anything manually whilst trying to get Safari re-loaded... ?
If not, I do suggest you use Disk Utility while booted from your install disk to Verify the HD, and then startup normally & repair disk permissions from Disk Utility found in Applications/Utilities/
If that all seems fine, obviously you need to get that file replaced, and hope that it's the only one missing/mangled ( often does seem to be the case )
Either archive/install Tiger, followed by all necessary software updates
or
Hope that it's part of the 10.4.11 combo - http://support.apple.com/kb/DL170 assuming that the file doesn't stop Installer from running.
or
bring /System/Library/Frameworks/Security.framework over from another mac running the same OS version, place it exactly where it should be, and hope that it's the only thing missing/mangled ( often does seem to be the case )
I don't know if it's part of the 10.4.11 combo, haven't a copy to hand. Also, there might have been other reasons, (and a whole different report), why Safari first started crashing. So you may find the archive/install less trouble overall.

WONT START AT ALL
