Blue screen hangs logging in as main user (tried extensive troubleshooting)

My systems state has been progressively declining...
First symptoms: while using my external FW drive, under heavy read/write use the drive would unexpectedly unmount, giving the "unmount your drive before disconnecting it to avoid data loss" message.
I ran DiskWarrior on the external drive. It still would unmount. Somewhere online I read that zapping the PRAM may fix it. I did that. That's when things got bad.
My computer began beachballing all over the place, so I rebooted. Full disclosure: it's been running slow sometimes due to the SOHO Sync process (I am running the SOHO Notes 5.7.0 beta, and I haven't ruled out this software as the culprit). Upon reboot, it would hang on a blank blue (aqua) screen - after the gray screen but before the login window or anything.
I booted into single-user mode and ran fsck. It found nothing wrong.
Tried to boot into Safe mode extensively. Sometimes I could get to the login screen. Tried extensively logging in as my user, it would just hang on a blue screen. The secondary user works, although sometimes verrrry slow (beachballs).
I began following the instructions in this article. Many of the first solutions (#'s 1-3) involve Safe mode, but since my account couldn't get into Safe mode I began moving Preference files and such using single-user mode (#'s 4-6). On step 7, I got through items a-m, but the rest of it is contingent upon being able to log in, which I still was not.
Using the secondary login, I was able to open Console and glean some information from that. mdimportserver was crashing over and over again, sometimes causing crashdump to crash as well. I figured this explained the slow performance and intermittent beachballing while using the secondary user. lsregister was also crashing occasionaly. In system.log, I saw several I/O errors.
Finally I decided to run DiskWarrior from the CD. It found some errors (I can post the report later) and corrected them. I rebooted, still would blue screen on my login name.
I reset the PMU. After this the secondary user ran pretty much normally for a short time. I removed the couple third-party mdimport files (Spotlight plugins) I could using the list dump from running mdimportserver -L and renaming the third party ones. (I know SOHO Notes includes Spotlight support now, but I could not find their plugin for the life of me, I'm not sure how they have enabled Spotlight support).
Still getting I/O errors in system.log. The secondary user is not working very well anymore (slower w/ beachballs).
This whole time the SMART status of my boot drive has been "Verified"
So - is my drive dead?
PowerBook G4 1.5Ghz (12) Mac OS X (10.4.2)

Update:
Using the secondary user in Safe Mode has allowed functionality enough to reformat an external drive with Disk Utility (although the drive spun down and Disk Utility didn't do anything while still saying 7 minutes left on the zero-all operation).
I force quit Disk Utility and reboot into Safe Mode. Got the startup progress bar, then the blue screen, then the screen went to a black with white lettering saying:
<time & host name> getty: /dev/console: Operation not supported by device
Then it would go back to aqua blue for a few moments, then back to this.

Solved Mac Mini (late 2010) Blue Screen Hang issue

I posted several questions about blue screen hang and was able to fix my problem, after LOTS of work and searching in various forums.
I had been unable to use my computer for over a month; it was simply hanging at the blue screen, and that seemed to happen when my Finder.app had crashed, hiding all my document icons on my desktop, etc. I also had been having issues with Time Capsule and my backup Iomega disk, which is touchy.
When I tried a fix my icons had returned but I had been unable to use computer after rebooting, and I had tried every sort of key combo including trying to boot from the original install CD, etc., but nothing worked. I could not even reboot using original 10.6 software CDs, and was only able to log in Single User Mode and had tried many fixes with Terminal, and finally, this worked, two of the fixes I used are listed below.
It seems, in part, that resetting certain "privileges" worked.
This tip first tip is for Mac OSX 10.3 to 10.3.9 and even though I am on 10.6.8, I ran it, and it worked. THis is the original link location: http://support.apple.com/kb/TS1411
   1. Start up the computer in Single-User Mode.
   2. Type: in Terminal the command
     mount -uw /
   3. Press Return.
   4. Type (in Terminal, note space before mv)
      mv /Library/Preferences/com.apple.loginwindow.plist preferences2.old
     Note space between ".plist" and "preferences".
   5. Press Return.
   6. Type:
     mv /Library/Preferences/com.apple.windowserver.plist preferences3.old
   7. Press Return.
   8. Type: reboot
   9. Press Return.
Then I followed up with this tip to "Reset certain privileges"
1. Start up the computer in Single-User Mode.
   2. Check the volume with fsck.
   3. Type: mount -uw /
   4. Press Return.
   5. Type: chmod 1775 /
   6. Press Return.
   7. Type: reboot
   8. Press Return.
When I rebooted, yayyyy! I was able to log back onto my computer, however, all icons were missing, again, so I typed this fix
/System/Library/CoreServices/Finder.app/Contents/MacOS/Finder & disown
I am not sure what 1775 means, but this fix got my computer back up, saving me at least a $150 bill at the Genius Bar.
When I typed those commands into Terminal, this is what returned, and seems to be some QXPscrpiting issue, though I have no idea what that is. and again, some Dropbox issues. If anyone has any idea what all those issues are regarding ScriptingCodes please let me know.

Great work, thanks.
As far as those errors, ypu have some missing OS components it seems.
And, before the mount -uw you really should've done this...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

MSI X99 SLI Plus - Blue Screen at Log In

After my $2000 computer died, I rebuilt using a new MSI x99 SLI plus motherboard, 5820k cpu, and ddr4 2600 for $1100.
It has been 18 days.
I was questioning the motherboard since the beginning since USB devices seemed to go in and out as if they were being plugged in in the middle of working, but I got around most of the problems by not allowing the PC to go into sleep mode.
This morning I wake up and go to check my email and the computer does a wake-up that is different. The bios screen comes up and then I see "resuming windows..." It gets to the log in screen and I enter my credentials. A few seconds later blue screen and reboot.
I try safe mode - log in, blue screen, reboot
I try system restore to a week ago - log in, blue screen, reboot
The store is not going to take any components back, they have a 15 day return policy and it has been 18 days. Nice!
I am not sure whether or not I can really say it is the motherboard. Maybe it is the GPU, who knows?
Anyone know of a way that I can get the details of that blue screen when I cannot even log into safe mode to look?
What kind of troubleshooting would you try?
I am ready to swallow a shotgun.

a roll back may have fixed it but it just depends when it was last updated! - i mean when was the last time that image you where trying to roll back to last updated was it before your problem started?
Everything was working as of 4:00am Central Time Today (11/7/12).
Blue Screens after log in started as of 9:30am Central Time Today.
There has been no windows update between 4:00am and 9:30am today that I am aware of.
The rollback to restore point was to 11/4/14, which would go well beyond any update if one did occur, which it couldn't without my clicking the install updates button manually.
There was no new hardware installed and no new driver updates done between yesterday and today. I played a few games and went to bed :p
Quote from: badboy2k on 08-November-14, 06:39:33
a blue screen when windows trys to start is usually it running the drive in the wrong mode: enter your BIOS - go to settings - advanced - integrated Perifirals - SATA mode (see if that is in AHCI mode)
I'll double check the BIOS in a bit when I get home from work, but again, I don't see how the BIOS setting would change all by themselves, unless there was a power outage or surge. Neither of those occurred.
I think all signs are pointing to hardware failure. Either the motherboard, GPU, or RAM.
I'll do a memory test and if that doesn't shed light, a reinstall of Windows, if that doesn't fix it, I'm RMAing.

Can't log into my main user acct! How can I fix this? Help, I'm stumped!

OK, here's the problem. While using my machine with VMware, I got the beachball of death. Nothing would respond and no keystrokes would bring up force quit. I finally had to press and hold start to shutdown.
When I restarted my machine first the grey screen came up and then a grey progress line was shown and finally completed. After that, the regular log in screen came up.
Here is where the problem begins. When I go to log in, (enter my password) it pauses briefly and then a blue screen comes up for a moment, and then it returns to the log in screen. This is a never ending cycle and the same thing happens if I shutdown and restart.
I can however log in into the guest account OK
Here's what I've done so far. Opened Disk Utility from guest acct and repaired permissions and reset PRAM. So far no luck,
If all attempts to log in fail, can I access my main user files from the guest account? I suppose if I have to reload everything I can restart in Target mode and get everything off to an external HD.
Please, if you have any suggestions, please let me know! Thanks!!!
Dan

Failed 10.4.7 update has caused blue screen at log on

I tried to download the 10.4.7 update (133MB version) to my 15" MBP and for some reason the download failed. Now I cannot start my MBP- after the Apple screen it just goes to a blank blue screen and stays there. I have looked for advice on the discussions board and tried the following things-
-starting it in safe mode and deleting the log in items (in both user accounts), that didn't seem to make any difference
-restoring the firmware as per the advice at http://docs.info.apple.com/article.html?artnum=303469, nothing happened when I followed the instructions, just started up again with that blue screen. Problem with this step is that it only works if you haven't since updated the firmware and I suspect we have since we do most of the updates that come up with Software Update.
Any other ideas before I take the computer back to the shop?
MBP, Mac Mini Mac OS X (10.4.6) still learning how to use my Mac...

To solve this, I downloaded the upload using the other computer and put it onto a cd-rom. Then I started the computer in safe mode, then pu the cd in and continued the update. Seemed to work a treat.
Might help someone else if they get any issues similar to this in future...

Ibook G4, OSX 10.4 and blue screen/hangs

My wife's ibook is acting very erractic. While using it today, it locked up and would only proceed to a blue screen upon reboot. I finally got it to start using my install disk to run disk repair. After running it twice, I finally got it to reboot. Ran Disk repair again. Now it will book and you can log in but when the system is inactive for about five minutes, you get a black screen. If you close the laptop, it has a blue screen when reopened. My questions are is this likely to be a hardware or software problem? I believe that it is a software problem but I would rather not do a full re-install. Any advice would be appreciated.

Hi Jeffery, it actually sounds like a hardware problem.
http://www.macintouch.com/readerreports/ibook/topic3417.html
http://www.applefritter.com/node/10193
I believe that it is a software problem but I would rather not do a full re-install.
If so, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

Blue screen when logging into windows server 2008 r2

when logging into windows server 2008 r2, all I have is a blue screen and the mouse.
I tried looking for solutions on the internet, then I found a microsoft hotfix "http://support.microsoft.com/kb/2590550" I run the hotfix in command line but it gave me nothing, no error or success messages.
I tried to reboot but I still have the same problem.
Is there any solution to this problem ??

Hi,
Thank you for posting in Windows Server Forum.
Did you face this issue during remote session or console session?
In addition, have you try to change or install any driver\software which cause this problem?
Have you use any debugging tools from Microsoft to find respective error cause?
You can refer following article for memory dump.
How to read the small memory dump file that is created by Windows if a crash occurs

Hope it helps!

Freezing with blue screen & can't boot from single user mode or disk

My keyboard is wired and plugged directly into my Intel iMac running OSX 10.5.8. I do not have the Leopard disks, but I do have the Tiger disks. I was trying to boot in single-user mode so that I could run AppleJack to try to fix another issue I'm having--I get the light blue startup screen flashed at me several times daily for the past week or so. When the blue screen flashes, it totally freezes my computer (obviously) and lasts from 1-10 seconds. I can't find anything that is triggering it. I haven't installed anything new that I'm aware of, and it happens whether the computer has previously been slept or not. I'm also not using an external display / additional monitor.
Also, for anyone who is nice enough to answer, please explain everything--I'm not an expert user.

Well since it is so time consuming and a security risk to turn off FileVault, I was hoping to hear from someone with more experience if this was the solution, or just something to "try"? Are you speaking from experience or just making a suggestion, leroydouglas? Thanks.

Help! Blue Screen hangs on G5 after installing Radeon 9600 pro...

Hi
I am having major problems with my G5, after working out that my old graphics card was knackered i bought a new ati radeon 9600 pro.
Every time i start up i get the apple logo then it hangs on a blue screen. I can get it to boot in safe mode and i've tried uninstalling the ati software and i've even re-installed OS X and wiped the disk to no avail.
I've also downloaded latest card drivers and looked for help on ati website but no real help there.
I would appreciate any help.thanks

I just installed an ATI X800 XT and it does exactly the same thing. Even on a new system build. Ironically enough I just took out a Radeon 9600XT that worked fine. Have you found a solution yet? I think I'm going to try and reset my pram. I'll let you know what I find out.

Blue screen with Discoverer 3.1 End-User

I have a workbook with four worksheets. With one of the worksheets (the other three seem fine) I get a blue screen on my workstation when trying to export the workbook to MS EXCEL. The worksheet in question has approx. 20,000 rows. I have export other worksheets that had over 50,000 rows without an issue. It seems, that when this worksheet exports, it suck all resources for my workstation.
Looking for help

I haven't seen what you are mentioning yet. However, if you create a calculation or parameter in 3.142 and one of your users still has 3.141, the user will get an error message: Invalid combination of filters or calculations, query cannot be resolved. Upgrading to 3.142 corrects this for the user.

Blue screen - What log in windows show the error?

Hi
I get a blue screen, but not Windows blue screen of death(BSOD). Sometimes it goes grey. After 5-10 seconds the alarm for hardware failure comes .....
Is there any windows log that can tell which part of the hardware the cource the problem ?
Run on windows 7 home edition.
Thanks in advance
Regards
Brian

With only 139 events in the log there is not much to go on. You are having BSOD'S and might want to check for DMP files (instructions in the below wiki)
I suspect much is going on in the system because of the high number of errors and critical errors in the 139 events. I would check for DMP files and run a system file check to verify the OS
We do need the actual log files (called a DMP files) as they contain the only record of the sequence of events leading up to the crash, what drivers
were loaded, and what was responsible.
Please follow our instructions for finding and uploading the files we need to help you fix your computer. They can be found here
If you have any questions about the procedure please ask
Please run a system file check (SFC) & DISM if you are on win 8 or higher
All instructions are in our Wiki article below...

Boot up blue screen hang/cycle (dark/bright)

Hi all
i have the above problem,
i did clean reformat (full re partition) ... it works on start up ... but after 1 reboot ... it will hang at blue screen forever with the blue cycling from darker to brighter ... the apple rep say it my 3rd party HDD ... but the hardware internal self check is passed ...
the local apple support Eserv in singapore is very unhelpful ... i cant solve the problem. the rep says at first it is my OS that konks up (hello it is apple OS)... then when i insist to check it then they accept my MBP for servicing. after it goes in, i suspect that it wasnt checked properly because they called me up very quickly to ask me to get it back. to solve the apple software problem they ask me to pay them $150 just to load the OS and check it, WTH is wrong with them? are they not the authorized apple agent? if the HDD is really at fault why did the verify option green light all my partition checks? if the HDD is faulty why did all my past 12 OS clean re-installs are done without a hitch but only hangs after a reboot?
i am very frustrated
does anyone have a similar case problem and confirm that it is a logic board change? because my friends did had 1 done

First thing I'd recommend checking is to see if your internal HD is selected as the startup volume. System Preferences - Startup Disk - ensure internal HD is highlighted. If it is not highlight it then click restart.
If it was highlighted then do a SMC reset:
_SMC RESET_
• Shut down the computer.
• Unplug the computer's power cord and all peripherals.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
_PRAM RESET_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Finally if you are turning off your computer when you're done with it daily please read your owners manual where it says:
_Putting Your iMac to Sleep_
*If you‘ll be away from your iMac for less than a few days, put it to sleep. When your iMac is in sleep, its screen is dark. You can quickly wake your iMac and bypass the startup process.*

Blank Blue Screen After Log In

Hello ladies and gents...ill describe the problem im having and how it occured.
I was browsing the web and playing music when my Powerbook G4 froze suddenly. I did the usual and restarted it. After the loading bar that says "Starting MAc OSX" appeared and fully loaded it went to the normal blue screen that appears when loading the whole desktop and dock...however nothing appeared and it just stayed there. I could still move the mouse around but thats it. I restarted again and was taken to a black screen and DARWIN appeared i put in my username and password and then it said "Welcome To Darwin". I let the powerbook sit for like 2 minutes and it went back to the Blue screen again, nothing loaded. Im basically at a standstill on what to do. I Do not have the installation CD's that came with my powerbook and I dont know what 2 do.
Anyone know a solution to the problem??????
And another thing, if its some sort of harware failure is there a way i can get my programs and digital design work onto an external harddrive i realllyyyy cant afford to lose that stuff.
Help is greatly appreciated.

See if this works...
Might 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.
