I see a blank blue screen at startup

I see a blank blue screen at startup. Am I going to lose everything that I didn't backup?

So I booted off the install disc (hold C at startup), did an archive and install) and then shut it down. Powered it up and zapped the PRAM at startup (commandoption+PR) and it now boots instantly. Just curious as to what video card you have in yours? I've been reading a lot of threads about problems caused by the ATI Radeon HD 2600, which is what I have in mine. Sounds as if a firmware update is needed, but not yet available. I also had 4 kernel panics in my first 20 starts. Apple Genius Bar said this was due to Symantec Anti-Virus for Mac.

Blank blue screen on startup

This has been an intermittant problem lately. When starting up the computer I just get a blank blue screen on the monitor. Other times the monitor just shows the clock marks going round and round and seems frozen. A quick push of the power button will put the computer to sleep then when I wake it from the keyboard the dashboard and desktop icons appear but with a blank grey screen, not with my chosen wallpaper.
A restart will just bring me back to the blank blue screen. Powering down seems to reset everything and I get the normal bootup action on the monitor. What's going on?
Mac mini Mac OS X (10.4.9)

Another blank blue screen at startup issue

Can anyone shed some light on this?
The iMac was operating fine up until a few nights ago. I had been using the machine all day without a hitch then in the evening tried switching to another user account and the system hung up stuck with the spinning pinwheel before login. I forced a reboot and got the blank blue screen.
I did all the recommendations I've seen posted here before. Repair Permissions and Disk Repair from the Install Disc (neither of which returned any issues) I rebooted in Safe Mode which runs fine but after rebooting I had the same problem. I booted Safe Mode again and tried making new accounts, that wasn't any help. I then went into single user mode to wipe out the preferences and netinfo database. No luck. reset SMU, reset PRAM, reset NVRAM, unplugged all external devices and pulled out the 3rd party RAM (bought it in 2005 from Crucial when I bought the iMac). No Go.
I reinstalled OSX using the Archive feature and that didn't fix things. Then I reinstalled OSX and let it wipe the entire HD clean after using Safe Mode to back-up my essentials onto external USB HD first. Even the clean install didn't help. It certainly runs a lot more zippy but it only runs in Safe Mode.
I ran the extended hardware tests from the Install CD/DVD and everything passed OK.
Now, there is one issue I can't solve myself and I have to wonder if this may be the cause of the problems, even though hardware tests don't reveal any problems. When I opened the case to pull the RAM, I noticed two capacitors on the logic board that had leaked, however the leaks are all dried up and crusty, not wet like a recent leak. Here's a photo:
http://www.mikepipes.com/sketchbook/imac-1.jpg
Is there anything I may have missed?
Now I have seen the other posts regarding the repair programs Apple has for certain model of iMac, and my serial number does fall within the range (QP519XXXXXX), however this is a 2nd generation iMac and the page states that only 1st gen iMacs are elligible. Wonder if the photo of the leaky caps could sway them to make an exception?
I'm trying to get as far as I can through troubleshooting because the closest Apple Store or Apple tech is 3 hours away.

Present you case to Apple. If you don't get anywhere w/them then ask to be transferred (or call them yourself) to Customer Relations - 1-800-767-2775.
Otherwise, you will have no alternative but to take your computer to your local AASP.
If you have AppleCare, you can have the repair tech come to your home (under certain conditions). Read the small print in the AC booklet.
You can also check AASP or AASP's Outside of the USA to find a repair shop closer to you.
*PS Thank you for providing detailed info about your troubleshooting efforts. It was a great help.*

Blank Blue Screen at startup lasts a llooonnnnnggg time - 3-4 minutes

What else can I say? It just sits there for a long time, 3-5 minutes. Then it finally starts running and gives me the login screen.

So I booted off the install disc (hold C at startup), did an archive and install) and then shut it down. Powered it up and zapped the PRAM at startup (commandoption+PR) and it now boots instantly. Just curious as to what video card you have in yours? I've been reading a lot of threads about problems caused by the ATI Radeon HD 2600, which is what I have in mine.

Blank blue screen at start up

Hello,
I have a newer iBook and somehow it got stuck on blank blue screen upon startup. The normal screen no longer appears where I am expected to enter my password etc.
A friend was recently using it only watching videos & movies while we were traveling.
Not sure if she accidentally entered a command but, now I can't use the computer at all.
How do I reboot/reset it without losing my data etc. Or is there a simpler trick to get UN stuck from the blank blue screen?
Thanks for any help.

Startup stops in blank blue screen

I have an iMac G4 which has been running Leopard fine for months up until this morning. When I started it this morning it stopped booting at a blank blue screen. I have never touched any startup/system files that I know of. I have been able to get the computer to start into target disk mode to connect to my MacBook and I was able to start up holding down option to get to the disk select screen, but after selecting the harddrive it again booted into the blank blue screen. Attempting to start in safe mode only gets me to the gray screen with the apple logo. The only thing I can think of that may be related is that I installed a few updates last night through system updater. I can't remember which they were, but the computer restarted fine after I installed them.

I have this problem as well, but eventually I get a warning that the application "FileSyncAgent" has not launched, along with "ignore", "relaunch" and "reboot". This is apparently related to a .mac sync problem that I've seen discussed on some other boards, but with no solution. I can also boot into target mode. Since I'm travelling, I can't reload OS X 10.5 from my disks, and can't restore from Time Machine either. I think that for me, the answer is probably to reload the OS (and go through updates) when I get home. In the meantime, I'm more or less stuck. I have access to an imac, but not with Iwork, which I really really need right now.
This just stinks...

Satellite L500 - blank blue screen after login to Win 7

Hi
I have this laptop and i can start up the laptop and it loads fine to the login page i then can login but when the screens opens after login it appears as a blank blue screen with the document folder open i have no background picture and no startup menu nothing else except the document folder.
From there i can access my files etc and anything else internet etc everything but i dont know how to get the screen back to normal.
If i go on background display i can see the image that should be on the background and change it but nothing happens on the full screen.
I have no restore point as yet as new laptop for xmas, i do have backup discs but think its just something to do with the display.
If go into files and folders it shows me the icons on the desktop but all i see is this blank screen.
Any ideas please, if not would restore files work or full back up disc
Thanks very much for any help

Hi
Check this:
Click right on the desktop and choose Personalize.
There you should check the area: Basis design and design with high contrast
Choose Windows 7 basic.
Then reboot the unit.
Usually this should help to get the Windows 7 common design and desktop settings.
But if this will not help then you could use an fast solution which would be a usage of the recovery disk of HDD recovery option.
This would format the HDD and would reinstall everything again

Blank Blue Screen

Whenever I start up my computer, I'm taken to the HP startup menu, but whenever I try to boot menu or boot recovery, it takes me to the blank blue screen. When I try crtl+alt+delete, a black screen flashes but takes me back to the HP startup menu. Please help.

If the memory and hard drive tests passed, then you may only need to reinstall the operating system. Unfortunately, if you can't get to the recovery partition through F11, you'll need to use external disks. I don't see that recovery disks are still available to purchase for this system. If you created a set when you got the system, you can use those. Otherwise you may need to purchase a retail version of an operating system.

How can I fix a blank blue screen?

How can I get passed a blank blue screen?

There are several things you could try, as indicated by those mentioned in this Apple Support
article about how to resolve startup issues, and perform disk maintenance. Read through them:
•Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support
If you have the install-restore DVD for the system running in the Mac, that may help to start up
from and see if Disk Utility's repair disk could help. Of course, if there is a problem in hardware
a replacement hard disk drive may be necessary because these parts wear out.
A slightly different set of symptoms appear other Support articles about startup issues, but some
of the ideas are the same when attempting to resolve the cause at a user-level. If issues are too
difficult, you may choose to locate an authorized Apple service provider to have a professional
diagnostic test performed to determine if other things are behind the problematic Mac.
•Mac OS X: Gray screen appears during startup - Apple Support
•Your Mac won't start up in Mac OS X (Mac OS X Panther 10.3.9 or earlier) - Apple Support
(for later 10.4, 10.5, 10.6, 10.7 etc systems, see 'Gray screen appears on startup' above)
Links in these support pages (blue) are similar:
•OS X Mountain Lion: If you see a blue screen at startup
•OS X Mavericks: If you see a blue screen at startup
If you have an Intel-based Mac, some of the issues may be different than those with PowerPC
hardware; so it helps to be sure you have correctly identified the computer & its working OS X.
Good luck & happy computing!

Blank blue screen on macbook air

I've suddenly got a blank blue screen on a first gen Macbook Air (the Mac equivalent of the blue screen of death I'm afraid). It will run the start-up without a sad mac to the point of the blank screen and then nothing.
I suspect the hard drive, but would appreciate any additional information.
Is there any way to access the disk to see if I can get any of the data? (in truth it's my mother's computer and no, she did not keep a current back up)
M

Try starting up while holding the Option key down. That should prompt the Startup Manager window where you can select the startup disk.
If that doesn't help, try Resetting the PRAM
If that doesn't help, startup in Safe Mode
A Safe Mode boot takes longer than a normal boot so be patient.
If you can access Safe Mode, you may be able to retrieve files, but no guarantees.
To restart normally, click Restart from the Apple menu.
Tip... when posting for help, please tell us which OS X is installed. Some troubleshooting can depend on that.
If you aren't sure, when you are Safe Mode, click About This Mac from the Apple menu.
The version is noted there.
If you couldn't boot in Safe Mode, try repairing the startup disk.
For v10.7 or later, restart the Mac while holding down the Command + R keys so you can access OS X Recovery to repair the disk.
If the Mac has v10.6 installed, insert the install disc that came with the Mac.

Stuck on blank blue screen when booting- HELP!

When I boot up up I get the normal grey screening with spinning pin wheel, but then it goes to a blank blue screen and just hangs there. Tried resetting the PRAM but didn't work, also want to boot from the install cd but I can't the cd drive door to open from the keyboard button.
Help please!

Hold the mouse down during startup to get the drive to open.
Or use the OPTION key to stop at boot selector and do it then.
I would make sure to have a working bootable backup of your drive at all times, and an emergency boot drive/partition.
What might help:
Boot from another drive. Turn off journaling. Repair drive.
Once at Finder desktop, delete the caches folders on your main drive.
/Library/Caches
/System/Library/Caches
/System/Library/Extensions.mkext
If the repair was "successful" and DU is not 100% certain to see and fix all possible errors, for that Disk Warrior or TTPro would be needed.
At the least, repair from current DVD of OS X, or SAFE BOOT, or Single User Mode and run FSCK.
Then do Safe Boot from your main drive.
But do install OS X to another drive to work from.
PRAM only affects settings. If you mean PRAM/NVRAM from cold boot, that would help with corrupt nvram due to hardware changes.
If you have or suspect a corrupt boot drive I would invest in Disk Warrior and/or TechTool Pro/Deluxe to use along with Apple Disk Utility.

Blue screen at startup---have tried EVERYTHING!!! Any ideas???

Hi there, I've got a really frustrating problem concering my husband's iBook G4. One day he got home from work, tried to start up, and got only a blue screen (no cursor.) (This is shortly after updating to 10.4.11, incidentally...coincidence?) We went to the forums, and tried numerous fixes, including:
Booting from install and running disk repair (none needed)
Booting in target disk mode with my mac and removing the login.plist file
Removing all login items from both user accounts in target mode
Attempting a boot (and eventual restore) from the external firewire backup, but it won't get past the blue screen here, either.
It started up in safe mode a couple of times, and even restarted in normal mode once, but then in primary account froze back up after a few minutes. Then it wouldn't even start in safe mode.
Then we did an Archive & Install from the original startup (Panther) but when it got to the login screen, it wouldn't accept either user password (even though the hint indicated we were using the right ones) and then froze. It now won't even boot from this disk, or start up in safe mode.
Everything seems to be intact while perusing it in target disk mode; even ran a hardware test from the Apple Hardware Test disc and that all checked out (no idea if this would have made any difference, but I'm grasping at straws, here!)
I know we did a couple more things suggested in the forums/support pages, but I can't remember what they are at this point...my brain is fried! (Also remember following Apple's instruction's for what to do when you get a blue screen at startup...tried this first thing to no avail.)
Soooooo...any suggestions or ideas? We would greatly appreciate the help!
Thanks so much!
Jennifer

Hi Jennifer,
Ok, so...what's going on today is that Leopard will open to the login screen (sometimes I can log in but generally not), but then the cursor is frozen, as is the keyboard (can't type to login or use shortcuts) and even a usb mouse doesn't work. The only thing I can do is power down with the off button, and upon restarting, if I get past the login, get the message "Computer was restarted after Mac OSX quit unexpectedly" or something like that. (Just restarted from frozen login screen and got blue screen again.)
Wondering if it's Leopard or my wonky install (we started up in target mode, with the install disc in the drive, and opened the installer on my mac, then chose the broken mac hd to install to. Seemed to work, but may this be related to the driver issue you mentioned?) We did it this way (after doing a zero-out erase) because it wouldn't even start up from the install disc itself.
It sounds to me like this method of installing is okay. If you did not have the correct drivers, you could never get as far as you do in Leopard. I am wondering why you install with the disk in your Mac and not in the iBook.
Anyway, have reset the PRAM, still no luck. On the apple page regarding this procedure they mention a power management unit reset for ibooks...would this correspond at all to our problems? Is it something I should try or steer clear of?
Okay. Resetting PRAM was a long shot, but worth trying. I would steer clear of trying to reset PMU. That is related to sleeping, waking and such things and your problems do not seem to be related to that. Also, I have never reset PMU, but from what I recall, it sounded a bit tricky.
Am now attempting to reboot from backup. And yes, when I open Startup Manager, the internal hard drive DOES show up. If that means anything. Have a bootable backup (created with SuperDuper) which also shows up, but when I try to start up with it, I get stuck at blue screen (still.)
As far as the iBook hard drive is concerned, this is a good sign. I am thinking that perhaps the hard drive is okay and the problem is something else.
So, since the iBook originally came with Panther, and Leopard is really yet another unknown to throw into the loop, if I do another erase/install, I'm thinking Panther is the way to go? (Unfortunately we shared a family pack Tiger with a friend, and haven't got a hold of that install disc yet, otherwise I'd try Tiger, since it's what it was running and so is what the backup is, too.)
From what I have seen in the forums, when people are having startup problems, the last resort solution usually works. That is, they take the install disk that came with the machine (Panther in your case), erase and zero out the hard drive and then re-install. That usually seems to do the trick. What they have probably done is either replaced some corrupted piece of software or fixed a directory problem on the disk. In your case, you have already done most of this except not with the Panther disk. So, I think it is worth going through this effort with Panther. If this actually worked, then you could worry about how to update your software to where you want it to be. If it does not work, I would consider this more evidence that there is probably a hardware issue.
If this doesn't work (and would probably have to try in target mode again if the install disc won't open...) should I buy Tech Tool or Disk Warrior or just send it in for repair? I suppose there's a point at which I'll have to admit defeat!
Not sure that I caught this before. You imply that the install disk will not open if it is inserted into the iBook. Is this a problem that showed up when the blue screen business started? When you insert the disk into the iBook and then reboot that computer from the disk (pressing the C key during startup), do you get something on the desktop?
If, when repairing the hard drive with Disk Utility, you had received a message that the disk was not repaired, then a stronger utility would be a reasonable choice. But, that does not seem to be your situation. So, if it were me, I would probably not buy Tech Tool or Disk Warrior at this point. I do think that it is possible that these utilities might be able to do more troubleshooting than you can do with Disk Utility and the Apple hardware CD. Tech Tool in particular has some hardware testing capability. So, if money were no object, you might buy that and see if it can give you more detailed diagnostic information. Of course, these are purely my opinions. I could be totally wrong on any of this.
Oh yeah, I don't know if I mentioned this earlier or not but all the restarts yesterday were accompanied be a brief "whooshing" sound (like a fan) for a second or so, and once I got both that sound and a "boooooop" issuing from the innards. Not sure if this means anything or not, but thought I'd mention it. Maybe the hard drive is melting! (Also I get further along the startup route after it's been turned off for a while.)
This is worth mentioning and I overlooked it in your previous posts. The "booooooop" sound got my attention. When the computer is started up, one of the first things that is done is that there are some hardware tests performed. Apple does use some sounds to indicate certain problems. You can learn a little more at You hear "breaking glass" or "musical beeps" when you turn on your Mac. I don't know if you are hearing one of these sounds or if they are unrelated. But, I think that the "boooooop" sound in particular might be trying to tell you something.
Let me sum up my opinions (which could be dead wrong). I still suspect a hardware problem. However, maybe the hard drive is okay. I think it would be worth using the Panther CD to do another erase and install on the iBook. If you still do not have a working computer, it is probably time to seek professional help. (However, if you get to this point, it is conceivable that you could be having some problems with your RAM chips. If you have worked with RAM chips before, you could try to play games with them: reseating them and removing them one by one- if you have two chips. But, if you have not done this before and are do not have some familiarity with working on hardware of this nature, perhaps you should just leave this alone.)
If you need to seek some professional help, you might be able to try one of these options - If you have AppleCare, you should definitely give them a call. If you live close enough to an Apple store, you could take your computer to the genius bar and see if they can help.
Sorry that you are having such a hassle,
Rich

My imac starts up and goes to a blank blue screen

my imac froze and when i restarted the computer it went to a blank blue screen i can only acsess the system prefences the grey bar at the top is also gone all of my files are there pics,documents, music ect. but i cant click on anything i tried to boot in safe mode and it wont go into safe mode when i put my snow leopard disk in it wont read it how do i get the computer to boot in safe mode or restore the computer to an ealier day is there a way to manually go into safe mode or restore the computer

Manual instructions > Mac OS X: Starting up in Safe Mode
If you can't boot in Safe Mode, try Resetting your Mac's PRAM and NVRAM
When booting from the install disc make sure you are holding down the C key.
Restore... you need to be able to boot from the install disc and run Disk Utility. It's very possible the startup disk needs repairing.

Blank blue screen on macbook

I have a blank blue screen on my 2008 aluminum macbook how do I fix my problem?

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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 installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
