Gray Screen of death after kernel panic

Hi guys,
Today I got a kernel panic and after restarting my macbook pro (early 2011) it stucks at a gray screen (without the Apple logo).
I tried a SMC-reset and also a NVRAM-reset but this doesn't help. Furthermore I tried to do a hardware test and booting from my Snow Lepoard DVD but this doesn't work too. When I start while holding c key the gray screen appears but nothing happens.
I removed the harddisc and connected to my server for getting all my files. This worked so the harddisc seems to be ok. In Addition to that I replaced my 8 Gb RAM to the original 4 Gb but this doesn't heller einher.
Has anyone suggestions what I can do?
Regards robert

If you can get it to start, go into System Prefs and check your startup volume...

BLUE SCREEN OF DEATH! KERNEL PANIC! HELP!

Hi guys. What's up? I was using my MacBook today, and i left it there for a couple minutes. When i returned back i saw that it had got a kernel panic. It said "Please Shut down and hold the power button" or something like that. And i know that i was going to get a kernel panic sooner or later because i have had the spinning beach ball of death for about 3 weeks. Anyway, now when I turned off my MacBook, i held down the power button to do a firmware update. And it went to the blue screen, but it just stayed there for about 10 minutes, untill i finally just decided to turn off my computer again. So I turn it back on and it went to the blue screen, and like last time it stayed ont the blue screen. So i thought it was the blue screen of death. Please help me out here! I dont know what to do!

Holding down the power button does not do a firmware update. It just resets your computer. Firmware is the code that resides in your system's ROM that makes hardware run more efficiently, or have specific features enabled (such as airport cards having various speeds enabled).
You can try booting off the install DVDs to see if the system will boot at all (this will test whether or not it's the hardware). From the installer you can run Disk Utility to try to fix the drive and fix file permissions to see if that helps. If nothing helps, you can reinstall the OS by using an "Archive and Install" method, which will preserve your user files and only replace the system files.
Alternatively, if you have a Time Machine backup you can restore from that using your Leopard DVD.

Gray screen of death after installing 10.4.11 upgrade

I installed the recommended update 10.4.11 on my PowerMac G3 and restarted. I can't get past the gray Apple screen and spinning circle. Same thing happened yesterday with my iBook G4, but I was able to get started after resetting the PRAM and restarting in Safe Mode about 20 times. I was finally able to re-install the update. But today I can't even start the G3 in Safe mode.
Any suggestions?

I experienced something similar. Installation failed and when trying to reboot my computer got stuck on the gray screen.
I wrote a small HowTo that should help you: http://net3x.blogspot.com/2007/03/macos-x-1049-update-killed-my-mac.html

Gray screen of death after upgrade

I think I did everything right; backed up hard drive, then zeroed it out, installed Leopard, then used Migration assistant to bring in my settings and programs from the backed up drive.
Now, all I get is the opening chime, gray apple, and after about 2 minutes it stops loading and freezes.
I've run disk warrior and it says everything is ok.. and I can get the hard drive to come up on a firewire drive on another machine. Should this not have worked?? and what did I leave out or do wrong?

Hi John,
Can you boot from your install disk and check the hard drive for errors?
Insert the installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
If you cannot boot from your install disk, try booting in Safe Mode

Gray screen of death....after 3 reinstalls!!!

Ok so i have the infamous gray screen of death after installing snow leopard but i think mine is slightly different. I don't have the circle going round and round. I only have a gray screen. For some odd reason the first time it happened i held the mouse button, then the cd drive (empty) came out and then it booted up (odd). Then i reinstalled, still happened, and i held the mouse on restart and again it worked. But now this time i reinstalled again, obviously it isn't starting up but even if i hold the mouse button it still won't load. Any ideas?

If you can get it to start, go into System Prefs and check your startup volume...

Kernel Panics, Gray screen of death, and hard drives, oh my!

Last week, while performing multiple tasks on my G4, Safari froze up and completely locked up the entire computer. I rebooted by manually pushing the glowing power button the front of the tower. During reboot, I got the gray screen of death with the "you need to restart your macintosh... by holding down the power button for several seconds" message.
After a couple tries and getting that exact same gray screen of death, I started to worry about all my data.
I took both drives out of the G4 Quicksilver - one, a 500gb Barracuda Seagate (Master/bay 1), the other a 200gb Hitachi (slave/bay 2). I hooked them up to an older G4 and ran DiskWarrior and DiskUtility on both of them. The master drive had serious (>34%) fragmentation, which has since been cleaned up. The slave drive was relatively fine.
here's my current problem:
When I hook up:
1. Just the Master with no jumper pins, the drive runs fine, no problems, all settings and prefs are there, etc.
2. Just the Master with the correct pin settings, I get the kernel panic screen of death
3. The Master with correct pin settings and Slave with correct pin settings, kernel panic screen of death
4. If I swap the Master and Slave, and make the correct pin settings, the booting process starts and then I get a light gray screen with the "ghostbusters/do not enter" circle.
I put the original Slave drive in an external HD firewire enclosure, and it will mount on the desktop after the original Master drive has booted up - BUT - if I have the external drive powered up before I boot the Master, I get a gray screen with nothing on it - no message, nothing but grayscreen.
I've backed up my critical data, but would like to get these two drives back into their normal operating Master/Slave relationship that served them well for the last couple years.
Any help greatly appreciated.

New wrinkle:
This morning trying at boot up, the Mac chime sounded, the gray screen w/the apple logo appeared, and then the machine sounded like either the main fan or one of the two drives spun down. Shortly thereafter, I got the prohibitory sign again.
I rebooted and then got something completely different: a black screen with a small blinking vertical rectangle in the top left of the screen, with nothing else happening for a long time, so I manually rebooted and tried to boot into safe mode.
Trying to boot into safe mode gave me the chime, the apple logo, and then the sound of either the fan or drive spinning down and leaving me at the prohibitory sign once again.
Finally I option-booted to the slave drive and upon startup, received the following crash report, which might as well be in Swahili as far as my being able to make sense of it:

IMac won't boot! (gray screen of death?)

Hello,
I just had a kernel panic on my main iMac computer, so I had to restart it...
When it logged in automatically, it restarted again (by itself)...
Now, once it booted, I'm staring at the horrendous Gray Screen of Death/Doom...
No apple logo, no loading wheel, nothing... just a blank gray screen.
Please help! I have no idea how to fix this!
Thank you. All help is greatly appreciated.

Hi mik.e245
Pop in the Install Disk 1 that came with your iMac and run disk repairs as described in the articles below:
http://kb.wisc.edu/helpdesk/page.php?id=3810
http://docs.info.apple.com/article.html?path=DiskUtility/10.5/en/duh1018.html
Not always, but many times Kernal Panic's are associated with a ram issue's. If a ram module was recently added it may have become partially dislodged/unseated and needs to be reseated.
If your still having trouble run the Hardware Test from the same install disk as per this article.

Gray screen of death ... macbook boot failure

Three weeks old and getting the gray screen of death. Power up works but MacBook just keeps trying to read a video disk I left in the ROM drive. Gray screen with nothing else (no processing circle, no apple logo, just a plain gray screen). I could hear the rom drive cycling.
I worked with support via telephone and their solutions failed also:
1. power up, hold down the eject button (nada)
2. power up, hold down the mouse button (nada)
3. power up, hold down the apple key, the cntl key, the P and the R keys for two chimes (got the two chimes but nada)
Now it chimes when i start up but still sits there cycling the cdrom which has a movie disk in it.
The support rep asked me if there was a small extraction hole by the drive. HELLO: are you really Apple ??? On the new macbook?
The MacBook was delivered with 10.4.8. Wanting the large 10.4.9 update on CD for any future need, I downloaded the 10.4.9 intel combined update (larger than the other choice) and went with that not knowing which to use. However this was three weeks ago and the computer has been perfect. my session yesterday was perfect but I did 'brag' on the new macbook when a friend saw me using it. why does bragging cause boot failures? Murphy?/??????// HELP.
Black MacBook intel core 2 duo 120gb drive 2 gb memory Mac OS X (10.4.9)

My apologies to everyone if I raised an alarm. The hardware (i.e. the MacBook) is fine and the problem was that I am a new user. I have to say that Apple Support was unprepared to address the issue but I did resolve it myself by accident. Here is the resolution:
I looked up the SMC reset instructions on the Apple Support site as a next step and the instructions said to try 3 things before doing the SMC:
1. Force Quit (Option - Command - Escape)
2. Restart (Control - Command - Power)
3. Force Shutdown (hold down pwr button for 10 seconds
As a new user I could not know that the key with the Apple was the Command key, but I guessed since the words control and option were called out, it had to be the Apple key with the Squiggle.
I did each step but nada. I did get a different alert tone (lower pitch) after doing step 3. Each time I turned the computer off.
I then started over and tried again turning on the macbook from being off each time. I did step 1 and turned the machine off and then did step 2 and the computer came alive.
The system is just like I left it and the rom drive works fine. Again, my apologies to all you macbook users for raising any alarms. We are new to using Apple and have much to learn. I did not have any cheat sheets to work from so it took time. Many thanks for the responses.

Gray screen of death at start up

Hello all,
Today when i was downloading the latest updates for my mac and iTunes my system froze while trying to access my BAD hard drive. So i restart my mac and after the apple logo appeared the gray screen of death showed up. I tried every thing from PRAM reset to disk and permission repair. So please help me with this problem.
Thank you

If you are on Mountain Lion you can boot from the Recovery Disk that is installed hidden from your internal HD. You can Use the Disk Utility from there to repair disk and you can also use that on OS re-installation of your ML.
"OS X Lion or OS X Mountain Lion includes a built in set of utilities in the Recovery System. Restart your Mac and hold down the Command key and the R key (Command-R), and keep holding them until the Apple icon appears, indicating that your Mac is starting up. After the Recovery System is finished starting up, you should see a desktop with a OS X menu bar and a "Mac OS X Utilities" application window."

Gray screen of death.... Please help.

Wife's 27" iMac is giving us the gray screen of death. I tried everything I could:
Command + Option +P + R
Holding Option at boot to try Recovery
Command + Option + R (Internet Recovery)
Holding shift to get to Safe Mode
Inserting install disc while holding "C"
Installed Mountain Lion on my Flashdrive to try to boot from that….
ALL FAILED. Any ideas, guys? Please help. This Mac is just a little over a year old. just out of the one year warranty.

Thanks for telling us everything you did. However, you haven't given us any information on what the computer did. So there's not much to go on except a gray screen. Assuming the drive has not failed:
Install or Reinstall Lion/Mountain Lion 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 Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion 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.
If you are not able to perform the above then the drive has most likely failed and will have to be replaced. Take the computer in for service..

Qosmio F20 blue screen of death after shutdown

Hi there,
I get the blue screen of death after shutdown on my Qosmio F20 laptop.
Error is IRQ_NOT_LESS_OR_EQUAL.
I assume that it is somehow related to tv tuner card.
I have tried to restore system - no good. After restoration for some time it was OK. But then BSOD appeared again.
Sometimes it also appears when I connect USB HDDs or even when I insert DVD disk.
And for shure everytime I shut laptop down.
Has anybody got ideas?

Hi
Reading you last message I really dont know what you expect from this forum ?:|
We all here can provide only some suggestions and opinions.
Without any notebook tests and checks nobody will be able to provide a magic solution
I hope you understand this.
So back to the notebook issue.
There is a one way to find out if the issue could be related to the software or hardware.
You have to reinstall the notebook with the Toshiba recovery CD. If the same BSOD will appear after the installation from the recovery CD then the chance are that the hardware is faulty!
I think you should check this out.

Blue Screen of Death after GPIB Software Drivers 2.1 install, nipsbfw.sys, nipalk.sys

I get a blue screen of death after I upgraded the GPIS Software Drivers to 2.1. The screen complains about the following files: nipsbfw.sys and nipalk.sys.
I'll copy down the exact message and post it...

Hello fkwok �
First, make sure GPIB software driver 2.1 is the correct driver for your operating system and board by clicking here.
If you are using Windows 2000, this KnowledgeBase is extremely useful.
If these suggestions do not solve your problem, please post the exact message and I will look into the issue some more. Have a great day!

White screen of death after 3 mins of usage

Hiyah, so my iphone got the so called "White screen of death" after 3 minutes of usage, i've tried restore and all of that but without success.
What should i do?
Send it in for repair? (seems really ridicilous if have to since it was bought the same day)
or
Take it back to the store where i bought it and ask for a new one?
Thanks in advance, oh yeah.. i live in Sweden.

Standard troubleshooting steps in the following order:
1. Reset: Press the sleep/wake button & home button at the same time, keep pressing until you see the apple logo, then release. Ignore the slide to power off.
If no change, continue:
2. Restore your phone from your most recent backup, Note, however: if the problem is related to corrupt data in your phone's backup, while this will restore a fresh OS, it will also restore the problem.
If no change, continue:
3. Restore as a "new" phone in itunes & re-sync your content. All saved data will be lost.
If no change, make an appointment at an Apple store, as you most likely have a hardware problem. There are no more user troubleshooting steps available.

Gray screen of death on boot-up

I have a 2.1 GHz MacBook with a 120GB hard-drive that I bought last November. I've been doing a lot with video and music and I keep running out of disk space. So, I keep deleting files that I thought I didn't need. Unfortunately, I must have deleted something important (for the OS) yesterday, and now, when I try to boot the machine, I get the "gray screen of death". And, to make matters worse, I cannot find the boot-CD that came with the MacBook. I don't have back-ups for many of my files and am hoping that I'll be able to recover my files. So, I've just bought an external hard-drive (which I should have done before). Any ideas how I can get the MacBook to boot and repair the problem without the original boot-CD? Will I have to erase the hard-drive to repair the problem, and if so, will I be able to save the files first? Thanks!

Hi MB-GSofD,
Without the disc(s) that came with your machine, I'm afraid your options are extremely limited. You can try to startup the machine in Safe Mode (Hold Shift immediately on startup, until you get to the login window) but based on what you deleted out of the /System or /Library folders, you might just be dead in the water.
Are you near an Apple Store? Do you have access to another Mac, say a family member, friend, roommate, co-worker, etc? There is Target Disk Mode if you can get access to another Mac and a Firewire cable.
