Computer won't start at all

Hello
My Power Mac Quicksilver won't boot. I tried to turn it on this morning and didn't even get any noise of anything starting. The only response was the start-up button I pressed to turn it on lit up and stayed lit.
Any ideas? Thanks

Hi-
I don't really know what to do with that information. Is this a really serious fault potentially or is it, if requiring these actions, potentially easy but technically a job for a specialist?
You already tried resetting the PMU.
So, the article suggests testing the power supply, which requires use of a volt meter.
If you aren't comfortable doing so, an authorized Mac repair facility should be able to troubleshoot the machine for you.
Typically, if the power supply is not dead, then it may be the logic board.
Either repair may not be seen as economical.
There is a chance that the power button board has failed, but replacing it is the only way to test.
I'd like to be able to recover files but the cost of paying someone to fix it may not be proportionate to the life left in the machine.
Yes, the cost vs service life is of concern.
The drive, and your data however, are not a lost cause.
All you need to do is to remove the hard drive, and put it into an external housing something like this:
http://eshop.macsales.com/item/Other%20World%20Computing/MEFW91UAL1K/
After the drive is in the enclosure, connect it to another Mac by firewire or USB 2.0, and all your files should be as they were.
Installing drives in external enclosures is not a difficult procedure, so that part should not concern you.

My computer won't start up after i tried to install updates

last night my computer told me there were 5 new updates available and i tried to install them, and my computer froze so i manually turned it off. now my computer won't start up. i get to the gray screen with the apple and the circular icon that swirls around which makes you think it's doing something but nothing happens. in the hopes that my computer was loading the updates, i let it run all night, and 8 hours later it was still doing the same thing. now my computer won't start at all, and i know there's power to it.
HELP!!!!!!!!!!!!!!!

chiae:
am i looking for the Leopard installer or the disc that came with my Powerbook all those years ago?
You are looking for the installer disk for the system which is currently installed on your computer, which is Leopard according to your profile.
Will doing these steps erase my hard drive?
No. Running Repair Disk will not in any way affect your data or any contents of your HDD. However, if there are serious directory issues your data might be jeopardized even without running Repair Disk.
Your question suggests that you may not have an up-to-date backup, if any backup at all. That is one of the most dangerous things you can do. I suggest that you take steps to secure your data even before you do much more. If you need ideas on how best to accomplish this, please post back and ask.
While you are waiting to locate your install disk, here is something you can do right now, and it will not in any way endanger the contents of your HDD:
• Shut down the computer.
• Locate the following keys: Command, Option, P, and R. You will need to hold these keys down simultaneously later.
• Turn on the computer.
• Press and hold the Command + Option + P + R keys immediately after the startup chime.
• Hold keys down until you hear the startup chime for the third time.
• Release the keys and immediately hold down Shift key to start up in Safe Mode.
• Log in and empty Trash.
• Restart normally and log in.
Please do post back with an update or with further questions or comments.
Good luck.

My computer won't start up. The apple icon comes on with a grey back grounds band it stays there. What should I do?

Try starting up in
Safe Mode
If nothing changes then start up holding down Command+R and use DiskUtility to repair your Hard Drive and permissions.

I killed a MacBook Pro. Shutdown with flash in drive and now it won't start at all.

I may have killed my MacBook Pro OS X by accidentally restarting with a Flash Drive it it and now it won't start at all. Any ideas?

So it is powering on. You did not state that before. In that case:
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area 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 tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Also see this if above doesn't work:
Install OS X from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
      the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
           because it is three times faster than wireless.
This should install the original version of OS X that came on the machine.

Firmware update progress bar appears and computer won't start up

Hi,
I am on OS X 10.6 (the latest developer build, whose build number I can't remember and can't look up because my computer won't start up) and this morning when I tried to start up my computer, it chimed, the apple appeared but then a grey progress bar (like the one that appears during a firmware update) appeared at the bottom of the screen along with the customary spinner. This progress bar didn't update and after 10-ish seconds, it disappeared and left just the spinner. I left the computer in this state for 4 hours and nothing happened. It still starts up in single user mode (but I can't seem to get Open Firmware mode to load) and it starts Windows XP on another partition of my main HD.
When I start it in verbose mode, it says that my catalog B-tree has keys out of order and it is unable to repair them. Also, I get an error message from launchctl: "Bug: launchctl.c:2033 (23930):17: auditquickstart() == 0". Then later on it tells me to convert a few system plist files to launchd (all in the /etc/mach_init.d/ folder). The very last line says "launch_msg(): Socket is not connected".
I would rather not re-install the system, but if I have to, I guess I will. I appreciate any light that anyone can shed on this problem.
Thanks,
Kyle

Yes, they (the third-party utilities) both come on bootable DVD's. As I mentioned, since Snow Leopard was just released in its final version, the developers may be in the process of releasing updates.
Your situation is likely to be a case where the data corruption issue already existed before installing Snow Leopard, and the installation process made the problem more apparent (because something critical was installed where it was affected by the data issue).
It is a good idea to run +Repair Disk+ in Disk Utility on the startup volume before installing a major system update. Actually, I do it before any system-level update.
You should also have a backup (at least of your personal data if not the entire volume), in case something bad happens during a major system upgrade. If you were using Time Machine, the easiest recovery would be to reformat the internal drive and use the Time Machine complete volume restore utility to restore the volume back to the date/time state just before you installed Snow Leopard. Then, after restarting from that restored volume to make sure everything is working, start up from the Snow Leopard installation disc, run Disk Utility and use +Repair Disk+ (just to be sure), and run the upgrade to Snow Leopard again.
If you have a backup of at least your personal data, you may want to reformat the internal drive, install Snow Leopard and bundled apps, install your third-party apps from their original sources, update everything that needs updating, and restore your personal data.
If you don't have a backup, the best bet is to try either DiskWarrior or TechTool Pro. DiskWarrior is very specialized into repairing this type of data problem. TechTool Pro has similar capability, but it is a more general tool with other features.

Mountain Lion update, and now computer won't start up?

Writing this for a friend, as his computer is inop at the moment. Hence this message.
He has a new 27" iMac. He upgraded to Mountain Lion a few weeks ago, and then had intermittent problems with apps unexpectantly shutting down.
Now he did a ML update this morning, and his computer won't start up. It gets to the point of the Apple logo coming up, a progress bar, and then the spinning wheel, but then shuts itself down right afterwards.
A safe boot yields the exact same result.
Any thoughts out there on what he could try to get it up and running again?
Thanks much for any and all help.

Thank you for the fast response.
He was able to get into Disk Utility with the Command and R keys, but when he tried verifying the disk, in red it said 'Invalid Node Structure, volume could not be verified completely'.
He went ahead and verified it anyway, then proceeded to repair it. Howver, it stopped repairing, said it cannot repair, and that he should back up files and reformat the disk.
How can he back up his files? He cannot see a way to do it. Is there anything else he can do besides having to reformat the disk?
This is his first Mac (after much prompting from me to go Mac), and he's afraid he's now lost everything on there.

HELP PLEASE!!! Computer won't start up

Help Please!
My computer won't start up, when I click the start up button the light comes only once, sounds click (once) and that's it, no power up.
Because of the age, I knew that the battery could be the reason, so I ordered the exact same battery and replaced it today (following the instructions very carefully). Nothing changed. Then I read about the button for resetting the power management (the one below the ram memory), did that too...and nothing.
I read the manual, it talks about recently installed components (which I have not) and explains the meaning of the numbers of blinks the power light makes with this type of failure, 2 blinks=ram memory, 3 blinks...4 blinks..more than 5 blinks= take it to service.
If somebody could please help me, I would really appreciate
All the best,
Veronica

I had similar problems with my G5 2ghz dual PPC. Mine would turn on, sometimes the startup chime would sound, sometimes not. The fans would run and continue to run faster and faster until I shut it off.
The red light comes on by the way, when the internal plastic shield is not installed or seated correctly.
Anyway, I determined after fooling with the machine for several hours that the symptoms pointed to the video card so, on a hunch, I grabbed a hair drier, pulled the video card and warmed up the video card with the drier. Then reinstalled the video card, hooked up the monitor and hit the power button. Bingo, the machine booted normally. BUT, it would intermittently hang or act odd while running so, I ordered a replacement video card. Installed it and the problem never returned. Sadly someone stole the machine last month but it was in perfect working order at the time:(

Satellite Pro 2100 won't start at all - LED start flashing

My SP2100 has started having power problems, and now won't start at all. The AC adapter green LED is on, as are the relevant lights on the laptop body (although the 'battery charging' light always stays orange these days). When I attempt switch on, boot up starts (and has in fact been successful on occasion until this morning), however the battery indicator and the adapter lights start flashing, and everything shuts down again.
On the rare occasions when I get past this stage, the lights keep flashing, and the system soon shuts down again with a 'low battery' screen message. Until this morning, it would sometimes settle down, the computer stayed on, and the lights showed a steady state as normal.
I initially thought that the problem was obviously the battery or the AC adapter, but now I'm beginning to think that it lies with laptop's internal power adapter (although I suspect that the battery is probably shot following all this part charging and discharging).
Any ideas?

Hi,
I think you are right. Flashing LEDs are a sign that some hardware is faulty.
I can't say what's exactly the problem, this should be checked by a technicain.
On the other side I'm not sure if it is worth to repair such an old machine.
Bye

Computer won't start up after changing permissions.

I accidentally changed the permissions for all of the files on my hard drive. Now, Leopard won't start up. And to top it all off I conveniently can not find my Leopard disk. I did, however, locate my Tiger disk but the computer won't start from the CD drive either.
I also thought that I could install Tiger on an external Hard Drive using my sisters computer but Tiger would not install on the USB Hard Drive because it said Mac OS X could not start from the external hard drive.
It won't start up in "Safe Mode (holding the SHIFT key)".
Anybody have any suggestions?

You can, in addition to Barry's excellent suggestions, reset the SMU.

Help, computer won't start up

Help, my computer won't start-up now. I downloaded one of those free .swf converter softwares from the net and now I think in the restart process, which should've completed the download like it said, instead it's like I don't have any OS on my computer anymore. And if that doesn't make things worse I was trying to reinstall OS X and it wants to go the net to do that but when i try to it asked my to login to the apple store with the ID i purshased it with and I didn't buy it I downloaded it from a P2P site, so of course the apple store tells me when i login to login with the ID I bought it with so now what, I don't want to lose my file's what should I do anybody got any suggestion. This is what I tried so far.
When it starts up I see the OS X Utilities window
I clicked the the Disk Utility, and clicked my HD and clicked repair.
When it was done it said
The volume appears to be ok.
Volume repair complete.
Updating boot support partitions for the volume as required.
Now what, also I did it again after I held CMD + R
Still when I start up I don't see my hard drive just the OS X Utilities window.
Also when I downloaded the OS X 10.8.5 I saved it on an external but its plugged to my only computer and thats the one I'm having the trouble with, sorry about all the miss spelled words if you can read this and help please do...

Try booting from your system CD, run Disk First Aid from your Disk Utility and repair your permissions.

New HD not recognized - computer won't start

Powermac G4 MDD
Originally had 2 hard drives -- 60GB (jumpered as master) and 40GB (jumpered as slave)
The 40 GB failed and the 60 GB was diagnosed as failing so I purchased used Seagate 160 GB ATA/100 Hard drive
I installed the new 160 GB Hard drive in place of the 40 GB HD and used SuperDuper to clone the still working 60 GB drive. The files were all copied to the drive and the drive showed up on the desktop as a hard drive icon, and it was recognized in the System Profiler. However, I could not select it as the startup drive from the System Prefs window.
I then took out the 60GB drive and replaced it with the 160 GB drive jumpered as cable select and now the computer won't start up (flashing question mark).
What have I done wrong?

I read through all this and still have some trouble. The article says that in Disk Utility if I select the drive a tab named "Partition" will appear at the top of the window among the other tabs. It doesn't.
I noticed some differences in the spec for the 2 drives currently in the machine: specifically, the new 160 gb drive is formatted (right word?) as GUID not AMD as the old drive is. But I can't figure out how to access that "partition" option and make the change. Here are the spec from System Profiler:

Computer won't start from hard drive or CD, and won't perform system recovery.

I have an HP Pavilion g7-1314nr. Yesterday it froze and I held down the power button to turn it off. After turning it back on, it started a disk check. I turned it off during the disk check, and upon trying to boot it back up, it told me booting failed and to press CTRL-ALT-DELETE to try again. After multiple attempts, it stopped displaying this message. Under system diagnostics, I ran a boot test, and it failed. Attempting a system recovery brings up the start-up windows logo, and then a black screen with an enlarged cursor. This morning, I inserted a recovery disk and told it to boot from internal CD/DVD drive. Like system recovery, it brings the Windows logo, and then a black screen with an enlarged cursor. My computer is incapable of booting from either the hard drive or a CD. What do I do?

Hi @TeridaxXD001 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion g7-1314nr Notebook and issues with Windows 7 and starting up. I recommend to restore the BIOS defaults. You could restore the BIOS with this document selecting the reloading the BIOS default settings which should resolve the fan issue.
Here is a link to computer won't start for Windows 7. There is a section on getting past the HP Logo screen.
If that does not help at the end of the document it shows you to do a hardware test.
Please note remove any and all USB devices before troubleshooting. Disconnect all non-essential devices
Hope this helps you out.
Thanks.

ITunes kept freezing and now it won't start at all

It all started when I downloaded an iTune U class that contained a lot of videos and chose to download all old episodes. It turned out there so many that it would take 25 hours. I tried to abort the downloads, but apparently that messed something up.
First iTunes started up normally, tried to download "83 items" and then started to freeze up after a minute. I had to shut it down via the Task Manager.
Then it got worse, and now it won't start at all. After I click on the icon to open iTunes (I have Windows 8) the screen turns white, the blue wheel spins and nothing happens. When I hold the cursor over the iTunes icon in the task bar I can see two preview tiles (one for Download and one for iTunes itself), but both are blank (all white) and nothing happens - the blue wheel will spin forever. What do I do?
I do have the latest version of iTunes. If I uninstall and reinstall iTunes, will that solve the problem? And will the content of my library still be there? Thanks!

Hello, J Appleseed.
Thank you for visiting Apple Support Communities.
You can try an uninstall and reinstall of iTunes to see if that resolves the issue. Your iTunes library will not be deleted by doing this. However, this issue could be a result of multiple issues so an uninstall/reinstall may not resolve this. Below, I have included the best articles that will help you isolate and possibly correct this issue. Process each step and test the results after each step processed.
