Os 10.4 not booting... stuck at blue screen

As the topic suggests, my iMac G5 isn't booting properly, and is getting stuck after the grey apple screen,at a blue screen, with the mouse visible. It will start up in safe mode, but not in normal mode.
I've tried clearing the PRAM, resetting the SMU, I've succesfully completed a disc repair with no issues, and I've also done an erase/reinstall of the 10.4 OS.
Any thoughts or suggestions?

After software update, will not boot up past blue screen

I just did a software update and after restarting, the computer will not go past the blue screen with the spinning wheel at the bottom. Please help! I've tried everything under troubleshooting in the manual. Any other ideas?

Thanks, I was able to fix my problem. It was a software issue. Luckily I did a pretty good backup...I just forgot to back up 2 of my most used applications: iPhoto and Appleworks. They were on my laptop before I did the erase and install, and now they are gone. I thought they would be on the iBook install discs or the OSx software install disc...but no. They had to come from somewhere and I just cannot find them! I know I didn't pay for them. Any thoughts on where they may be? I am so mentally exhausted from these computer woes...I can't think anymore!!! Please help me!

Desktop will not load, stuck on blue screen -- please help!

As I can see, many other Mac users have encountered the same problem that I now have: the dreaded ‘blue screen of death’. About a week ago, any internet browser that I tried to open (Safari, Firefox) would freeze after loading its home page, and tell me that the application was not responding. After force quitting and restarting each program a couple of times, with no positive response, I decided to restart my computer to see if that would do the trick. Upon booting up, it then started the same sequence that it is still doing now: first a grey screen will briefly show, then a white screen with the apple logo and a turning dial beneath it, followed by a blue screen which will show a window that says “Starting Mac OS X” with a progress bar beneath it, which will fill to various points (sometimes only 1/8 of the way, while other times it fills completely), but it always leads me to the same screen – solid blue with a black arrow that will occasionally be replaced with a turning dial, only to go back to the arrow again. I am using a PowerBook G4 with the Tiger version of OS X. No applications were running whenever I first decided to restart my computer, and to my knowledge, all software and security patches were up to date and fully installed.
I’ve researched and tried every possible option that I’ve come across, listed below with the results they yielded (if any):
 Holding the Command/Option/P/R keys upon startup (screen stays blank, and the computer continues to ‘chime’ until I release the keys. I have allowed it to chime a couple of times before I stop holding the keys, but it always leads me back to the same blue screen)
 Holding the Shift key upon startup (leads me to a screen that has an icon of my hard drive and two arrows. Clicking the left arrow does nothing, the hard drive icon does not respond to being clicked, and the right arrow starts the loading process which again ends with the blue screen)
 With the first OS X Installation disc that came with my computer inserted into the disc drive, holding the C key (nothing happens; sequence as normal)
 With the first OS X Installation disc that came with my computer inserted into the disc drive, holding the Option key (same results as holding shift key with no disc)
 With the first OS X Installation disc that came with my computer inserted into the disc drive, holding Option/Command/Shift/Delete (a grey screen appears with the icon of a folder, a question mark briefly flashes before being replaced by the two-toned blue face Mac logo. After continuing to hold the keys with this folder and face on the screen, I get no response, so release the keys and the computer continues to enter the white screen-blue screen sequence)
 Holding the Command/Option/O/F keys upon startup (a white screen appears, and following advice I have seen on other forums a type ‘reset-nvram’, then return, then ‘reset-all’, then return. The computer reboots and the sequence continues as usual. I have also tried holding the Command/Option/P/R to reset the PRAM immediately after leaving the white Open Firmware screen, allow the chime to sound a couple of times as before, but still I get no results)
 While on the blue screen, pressing the Command/Shift/Q keys (alas, I am the only user on the computer, so I cannot try to remedy my problem by signing into another account. From the screen the appears, I can either shut down, restart, or put my computer to sleep, or enter my password which leads me back to the same blue screen again)
I apologize in advance if I’ve included a lot of extraneous information, but I just wanted to cover the options I’ve already explored so as not to waste your time if you had any of these in mind. I’m going to post this on a few different forums just to make sure I have all my bases covered, but anything you have to offer in the way of suggestions would be greatly appreciated. If you could post your advice in layman’s terms that would be even more helpful; I’ll probably need exact, step-by-step instructions if required to start my computer in ‘safe mode’ or anything else an average user would not be familiar with. I know this is a lot to ask, so I thank you in advance for taking the time to read through this and offer any solutions that you may have.

Hi amnicolekidman, and a warm welcome to the forums!
Although you don't specify your Mac, it sounds like you have real HW problems, likely the HD.
Tough without a Tiger Disk, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: ** The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

Then Safe Boot , (holding Shift key down at bootup), off the HD & use Disk Utility from there to Repair Permissions, reboot once more.

I can not boot past the blue screen, but safe mode is fine...

I have no clue what I did...
Everything was working fine on my iMac (which is from like 2008). I did a file migration transfer from my Macbook pro to the iMac and everything seemed to be good. I could see everything, etc. I went to update the software on the iMac since the computer has not been used in a while. After everything updated and installed the computer restarted and has not been able to move past the blue screen when booting. I can start in safe mode just fine. I have done everything I can find on how to trouble shoot with no luck.
I have reinstalled the OS X
I have held down every combo of keys when restarting the computer
I have made sure the correct disk is highlighted for starting up
I have done everything I could find online...
I do not have the option to erase under the disk utility, or repair?
I am so lost and have no idea what to do. Did the migrate do this? I could use any help! Thank you.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

N100 3000; Does not boot up; Lenovo blue screen

I bought my N100 few years back (Running Vista home edition). Battery has been dead for a while. It has been working fine by directly using the power source.
Couple of weeks ago, it restarted itself. But, it never got beyond initial "Lenovo" blue screen. Hard Disk light comes on momentarily, then nothing.... I can not even go to "Lenovo care". Nothing happens when I press "Lenovo care" button. The only button it recognizes is on/off button.
The only think I did a few days before this issue was using compress option to gain some space on my hard disk. But, did not see any issues after compress was done.
At this point, I will be happy to be able to recover my files from my N100 (I did not foolishly backup my files).
Any help is greatly appreciated.

F1 key did not work. My laptop does not respond to anything at Lenovo screen (it has white back drop not blue as mentioned earlier).
However, when I removed Hard Drive, it proceeded beyond Lenovo screen and displayed a message that OS is not present (Which makes sense). Does anyone know how I can get a boot CD? This way, I may be able to attempt running recovery utility on my Hard Disk.
Thanks,

W520 will not boot when docked; blue screen

W520 fails to boot 100% of the time when docked. Blue screen shows SYSTEM_SERVICE_EXCEPTION, STOP x0000003B for nvlddmkm.sys
nvlddmkm.sys is the NVIDIA driver, which is version 8.17.12.9620, the latest shown on the NVIDIA and Lenovo websites. BIOS is also the latest.
Systems boots fine if I remove it from the dock, but it will not boot when docked.
Windows 7 PRO SP1
2 external monitors via DVI
Any suggestions?

Boot with Option held down. After the cursor changes to an arrow, Command-. (Command Period) should open and close the optical drive. After you insert the disc, click the curved arrow to have it re-scan the discs for boot volumes. Then select the optical drive and click the straight right-pointing arrow to start.
Try it with the Apple Hardware Test disc first and run Extended Tests.

Won't boot, stuck at blue screen

I have a problem with my MBP.
I was working on it just like every other day. While listning some music, at some point i lose all sound. Tried the headphones, ... Nothing worked. Next thing i was rebooting the MPB like normal (apple, reboot,...). While it was rebooting, i passed the gray screen with the apple logo and the little spinning thing. After that i got to the blue screen and was able to see the mouse point. But that's it. I'm not getting my login window, no menu, ...
Tried the Leopard disk, and repaired the disk. Repair was ok. Same result
Tried to repair disk permissions. Got all kinds of warnings about SUID-files (usr/libexec/load_hdi , ...)
If you guys want to, i can put a link here to a picture of the whole list of permissions failure...
Tnx for helping me!
Sam

Yes I have, and i couldn't find it.
I haven't got the time for waiting for an answer cause i really need this laptop. While i was going over other topics one told me to reinstall using Archive and Install. I just couldn't wait, so i took the chance.
I thought i was going to lose some stuff, or at least preferences like my Adium look. I put in the Leopard dvd, rebooted with the "c" pressed in and reinstalled it (using the archive and install option). The system rebooted again. I finally got back my login windows, logged in, and EVERYTHING was identical: passwords, preferences, maps, startup applications, even the alarm on my Awaken
Tnx alot for helping me Apple forums!

Powerbook won't boot - stuck on blue Screen with rolling pin wheel

Hi, maybe someone could remove my current headache.
My old Powerbook G4 is stucked on a blue screen with an infinite rolling pin wheel(just after the little mouse arrow appears and disappears).
For the information:
- I already did all the possibilities on this page without success:
http://support.apple.com/kb/TS1411?viewlocale=en_US#symp1
- When I do Fsck in single user mode, it tells me that everything is fine with the HD
- I also checked techtool pro v4: everything is fine with the hard drive and files
- I can't start in safe mode
- I can't put my computer in Firewire target disk mode - the Fireware icon screen appears but it doesn't mount on my apple dekstop.
- I don't know where is my old PB G4 install disk, so I can't try that.

I don't know where is my old PB G4 install disk, so I can't try that.
And, there in lies the solution. Without an OS disc to repair the OS you are up the creek without an OS disc.

Macbook boot stuck on blue screen?

I was updating the Macbook software and restarted the machine like it said so. When it did though, it stayed at the blue screen and wouldn't do anything. I see the mouse and can move it around the blue screen but I'm just stuck there. Any help?

yeah that same thing happen to me. I updated then restarted it and it was stuck at the blue screen with the apple logo and the little spinny thing just kept spinning. Took it to my local apple store and they had to replace my hard drive. Just got it back and am now updating again. Hope your stuff is backed up and best of luck.

IMac does not boot, stuck on gray screen

Hi all,
Need some troubleshooting assistance.
Attempted to install a CAC card reader, with the ActiveGold software on my iMac.
Reboot when prompted, and now the iMac will not boot at all (even will not boot in safe mode).
Have removed all external devices, and no dice.
I used Disk Utility from the OS X CD to confirm the volume is ok.
Was able to access the drive from the bootcamp Vista using MacDrive and have copied the content I needed to grab - the volume appears to be otherwise ok.
Before I Archive and Install, wanted to get some suggestions.
Thanks

Ok, maybe with iMacs that come pre-installed w/Leopard it's on Disk 1. Did you check?
My MBP model, the HT is on Disk 2.
Anywho, try the following:
Except for the keyboard & mouse, disconnect all devices from your computer.
Repairing permissions from the Tiger/Leopard DVD
Boot up from your Tiger Install DVD while holding down the "c" key.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
If Disk First aid is able to complete the repair now click on the "Repair permissions" button.
Once this process has been completed restart your computer.

My intel iMac 2007 24" will not boot beyond a blue screen

I have checked the hardware and everything is good. I have used the disk utility and all is good what can I do next?

Did you repair disk permissions with disk utility as well, if yes then try to start you system in safe mode (hold down the shift key while restarting).

10.6.8 update stuck on blue screen... 4 hours and counting

Upon selecting automatic software update my system seems stuck on blue screen with spinning grey gear. How long should I tolerate this (going on 4 hours now) before attempting to do something?
I can access the hard drive of this computer from others on my local network and am able to copy files from it. I'm wondering if I should try to grab all that is valuable to me before anything worse happens.
Advise?

If your data is not backed up copy any important documents you can from your Mac's startup drive.
Once you are done copying your data, use the power switch to turn off your Mac and disconnect everything except a wired keyboard/mouse and monitor. Start up in safe mode by holding the shift key down right after you hear the startup chime. Keep holding down the shift key until you see the Apple Logo and spinning gear.
Mac OS X: Starting up in Safe Mode Mac
OS X: What is Safe Boot, Safe Mode?
Safe mode will do some maintenance routines and checks/repairs the disk if needed so it will take quite a lot longer than normal to boot. Once your Mac boots restart normally. It will take a little longer than normal to boot but not as long as booting in safe mode.
If things don't work as expected install the Mac OS X 10.6.8 Update Combo

10.5.3 won't install... stuck in blue screen loop

I chose to install it from software update. It told me to restart. I did.
I got hung up on a blue screen loop.
But no error messages or anything.
I had to hard reset.
Then started up fine- but system profiler shows I'm still 10.5.2.
And software update still shows the update as "downloaded".
If I click "install" it immediately asks me to reboot, and sticks in the blue screen loop again.
I have done this three times now.
If I choose restart from the apple menu- same thing.
So I decided to shut down- can't shut down. Get stuck in the looping blue screen.
So it seems like something is gumming up the shut down process. I've heard of startup items making things freeze- can the same thing happen when shutting down?
Not sure what the issue is.
The other people posting problems seem to be getting error messages, etc.
I am going to try to repair permissions, and if that doesn't work maybe I'll try the standalone installer- but why is this happening? this is like a 2 week old MBA with next-to-no third party stuff installed on it... what could be corrupted already?
fortunately I have backups if worse comes to worse...
Any other tips/thoughts?
Thanks!

You could try, it's been known to sort system issues because it's fuller than the incremental "delta" update, so it should overwrite any files that are damaged or missing.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
But if you can't boot into Safe Mode something is amiss*. Since, you are able to use your system (not stuck on blue screen, try this first:
Go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting.
*EDIT: You do have to hold the shift key for Safe Boot until you see the spinning gear, just in case you didn't do that.

GE60 0NC-622UK laptop is stuck on Blue Screen can't login! please help..

Had this laptop for just one month, before it's all good. Windows 8 64bit.
In last two days, the mouse and touchpad became dysfunctional occasionally, able to move the pointer but just could't click on anything regardless of left or right, e.g. choose or open new. It would be working after logoff/relogin and reboot, but same problem still came up randomly.
Last night, I did the same thing to reboot the laptop after had the pointer dysfunction, but then it displayed a blue screen before the login with a error called 'System Thread Exception Not Handled', and then just stayed on this page would't reboot automatically (waited for 30 mins), so it left me no choice to shut it down by pressing power on/off button manually, afterwards with couple of times rebooting, it just kept going into this same blue screen and could't get into the system...Sometimes it would automatically start diagnosing before blue screen, ask me to restore or repair, but none of them fixed the problem, repeatedly stuck on blue screen every time...
And I don't have any windows 8 dvd, delivered box only has one for drivers and manual book.. so boot from dvd is not possible..
p.s. sorry about my english if caused confusion
thanks..

Try starting Windows 8 in Safe Mode, its kinda difficult in Windows 8 to do you have to be very precise when doing it, right as the system boots you need to start spamming F8 sometimes you have to do Shift+F8.
You may want to disable fast boot in the BIOS so you have some time to get ready to hit the buttons, once you get the boot menu up try Start Up Repair first and see if it fixes anything then try booting, if noting then try safe mode and un-do anything you have done to the system recently.
Let me know how this goes.
Really appreciated your help!
I get into troubleshooting page by pressing F3 when laptop was booting up, and changed start up with Safe mode which works..I've done many things in Safe mode, like updated drivers, run anti-virus program, deleted recent installed software, and then somehow the blue screen error was gone after reboot...It seems one of them must be the cause for that problem.
Anyway, my laptop is working properly now, thanks a lot, if error happens again in future i might still need some help
