Software :: Ibook G4 Freezes Up - Restarts To Blue
Mar 27, 2008
I was working on my iBook G4 and it froze up on me. When I restart, it goes to the apple and spinning wheel then goes to a blue screen and sits there. If I restart it does the same thing. The only thing I have done for it to go to the login screen and not the blue screen is let it sit of a long time then try again. I have done a hardware test and everything passed. After much troubleshooting I figured I would erase the entire disk on the OS install and start over. I get about a quarter of the way through the OS install ( i have tried Leopard and after many freezes, reverted back to the original OS disk Panther) but I get the same thing everytime it just freezes. Usually everything freezes including the mouse pointer. My only option is to restart which gets me back to the blue screen. I have gone into the hard drive via firewire target disk mode and backed everything up. ANd everything seems fine in TDM. I also erased the disk through disk utility figuring if nothing is on the disk there should be nothing left to be causing this error. So i erased everything but still freezes up on the OS install.

I've been reading the other post and searching for ways to fix this. My ibook froze a couple of days ago, so I pressed the power button to do a hard turn off and then restarted it. It hasn't made through the blue screen since. It seems to load all way and then stops at the end, but stays on the blue screen. The mouse is not frozen though, I noticed that was a problem for some people. So I've already tried a lot of the suggestions I could find. I've tried resetting the PMU,Start your computer holding the ⌘ and S key on your keyboard. When the black screen turns up and the "writing" stops, you will see something like

I have an ibook g4. It freezes at the blue screen with the apply on it. The little circle goes around and around but nothing happens. I took it to an apple technician yesterday who told me the hard drive is toast so I should just throw it away. (Actually, he offered to take the keyboard.) When you do the fsck -fy it says that the hard drive was repaired sucessfully. Is it possible to have a hard drive that is bad and a message which says it has been repaired successfully? I don't mind having the hard drive replaced if that is what is wrong. I do not have any of the install discs any longer.

I have a problem with my windows partition. Every time it boots the blue beam stops in the middle and a blue screen appears, which I can't read because it disappears too fast. And than the computer restarts again. I also tried the safe mode but it didn't help either. So my question is: Can I fix windows from my mac partition?

Every hour or so, my computer freezes up and then restarts itself. Once restarted, it does an error report and tells me that "Sleep Wake" has experienced a problem. Is this a hardware problem? What I should do about it?

Finder will flick to blue screen for a split second and restart quitting all open apps. Not restarting the iMac, but just Finder? I've ran Disk Utility and found no problems and also ran a Hardware Test and found no problems. The only indication I have is in Console which without posting the whole log the below lines stand out to me as potential issues:
HIToolbox: received notification of WindowServer event port death.
This line is present numerous times with each application name that was open next to it indicating to me a reason each app has quit? Then a long list of this line repeated;
com.apple.fontd [58544] FODBCheck: foRec->annexNumber != kInvalidAnnexNumber (0)
Followed by:
com.apple.WindowServer[58526] WindowServer[58526] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
This happened once yesterday and a few times today so it's becoming more regular...

Today my imac done something wierd. When powering on it got to the blue screen before the password login and it just froze on the blue screen. I done a hard restart and rebooted a few times. Didn't do it any more after that.
Should I be worried? It's only a few months old.

I am a Mac-newbie who recently switched from PC to Mac. I know a little about comps and have some experience with Windows and Linux. Now the Mac. I upgraded my iMac 20" (bought it used from a friend) from Mac OS X 10.4 to Mac OS X 10.5 and everything seemed to go according to plan until it came to the re-boot and the comp froze on the blue screen with the movable mouse pointer showing. I tried the apple key with s on boot and did fsck -fy and fsck -f a couple of times. It only shows "The volume MacC appears to be okay". Everytime I typed "exit" to go to the log-in window it still gets stuck on the blue screen. I tried to start it with the installation disk in the DVD drive but now it doesn't eject it either anymore. So, the situation is: I have an iMac with that wont go past the blue screen, with a workable mouse pointer and a stuck DVD in the drive. I am extremely frustrated especially since I do not have a second Mac to read the HD in the iMAc with and I don't have a backup system (except my PC Laptop). What can I do?

My Mac will freeze at random moments (not while running any particular app or program) and go to a blue screen, after a few seconds it clears up by itself. Sometimes it will happen several times in a row, sometimes 10 - 15 minutes in between.

On my 1st Gen Mac Pro, I suddenly get a strange blue screen out of no where. Everything on the screen freezes for a few seconds then the screen flashes blue for another few seconds. After the screen comes back from the blue, everything works perfectly again. Even when listening to music, music pauses for a few seconds and then comes back. This happens a couple times a week and its getting on my nerves. Sometimes it lasts for a long time and requires a hard restart.
I have tried reinstalling Leopard/tried hardware test/upgraded to the 8800GT video card and the 3870/I cleaned the whole inside of the box with compressed air. I even took her into the apple store and had a genius look at it over night. They told me everything is working perfectly. Ofcourse it started doing it again after I got home with it. The apple store suggested that I could always replace the logic board but they want over $1000.00 for that and I dont know if its worth it.

My dual screens are flashing, sometimes fading in and out of blue. Sometimes when they flash back to my normal desktop from the blue, everything is frozen, I can't move the mouse or do anything. What is going on with this? I have a Mac Pro Tower, OS X 10.5.4, 2 x 2.8 GHz Quad-Core intel Xeon processing, 6 GB 800MHz DDR2 FB-DIMM RAM. I use this machine to run a recording studio. It is used primarily with a Pro Tools HD3 rig.

The LCD display on my ibook will get a intermittent blue tint. I have no idea what could be causing it. The LCD seems to be in good shape.

After installing an app ('Detour') I was asked to (or it was suggested that I should) restart my computer. I did so, and now my 1.33GHz iBook G4 turns on - but it will not go any further than a blank blue screen (after the initial grey screen that appears.) Thankfully, all my data is on an external drive. I keep my music and footage which I have shot on there amongst other things. I also have a backup on my external via Time Machine of all my data which I keep on the iBook drive, so nothing should be lost.

I just started my iBook g4 up and after the initial grey screen with the spinning thing and apple logo, it just stays at the blue screen straight after that. I have left it for ages and it is still there and I have tried several times now. Does anyone know what the problem is and how I could fix it?

My IBook G3 will not start up. I can get the gray apple screen with pinwheel and then after a really long time it will go to a blank blue screen. A couple times it went to the login screen instead but in the user id it says "other" and when I try to enter my username and password it won't recognize me. I am a college student and one of the Apple geniuses here did a check of my hard drive and it checked out okay. We were not able to get it to start up in safe mode; it seemed like it was starting in safe mode but then it came to the login screen and would not allow me to login with my usual information. I was able to start up in single user mode and run fsck which found a couple things and after another fsck it said everthing was fine. But, it still gets hung up at startup. When I try to boot from the OS X installation CD it doesn't seem to be booting up with it, it only goes to the screen to install OS X. According to the directions on the Apple support site when I insert the CD and start up holding down the "c" key it should start up and then I should be able to repair permissions but I can't get that far.

I am trying to reformat an iBook for a friend. Everything was running, but, there was no chime on boot. I logged into the machine, and was checking files and folders when it locked up. It actyally locked up while trying to run Microsoft Word. It now boots to a grey screen the the little "spinning" thing, and then, instead of going to the login screen, it just turns blue. It will NOT boot into Safe Mode, it will NOT boot to the iBook Install CD, I just get the same blue screen using both methods. I used Command-Option-P-R without success. I booted to Open Firmware and typed reset-nvram without success. I don't know what else to try. I am copying her files right now by booting into Target Disk mode, but, once I get that done, I still won't be able to boot the install disc to get the system wiped and reinstalled. What else can I do to correct this?

I was using my Mac (Macbook Pro 15" screen) and tried opening a file in GarageBand, at which point a warning message came up saying something about a midi file and something not being allowed, and then froze, resulting in me having to switch the computer off from the power button and restarting (Sadly I didnt realise that this would be the start of a whole host of problems and didnt make a note of the warning message). After rebooting I got the 'stuck on the blue screen with the Apple logo and infinitly spinning wheel' problem that i've seen in a few posts. having tried numerous suggestions posted with no change I ended up taking it to the genius section of an Apple store. When i got it back they said that it may have been a corrupted file, and that they re-installed and reset the starting programs (Something along those lines, I cant quite remember). I can now get onto the computer and use it, though some new problems have arisen.......

I have a G4 iBook - 1.07Ghz, 768Mb RAM, Panther - that keeps giving me the swirling beachball of death depending on the date setting on preferences. If I set the date to 2004 the machine runs fine, but if the date is set to today or (I'm not sure of the exact date) after 2007-ish the thing keeps freezing.
Also, after the freezing troubles I installed Ubuntu and it ran perfect with the correct post 2007 date.

I sent in a question, but I thought I would also post a thread in case anyone else might have some helpful suggestions.
I have an iBook G4, Tiger edition 10.4.11, 1.07 GHz, 768 MB DDR SDRAM.
My system sporadically freezes. Whenever it is moved (i.e. resituated on my lap, or from my lap to the table). Or if I leave it unattended for a period of time (i.e. downloading something, and walk away, by the time I come back it's froze if I am not constantly DOING something). Or if I try to access 3 or 4 applications at a single time.
Sometimes the freeze is a complete system freeze where nothing works or moves. Sometimes everything but the mouse freezes and I can still move the black arrow around. Sometimes it freezes and the little beach ball just keeps spinning, but is still mobile.
Sometimes after it freezes it will not restart. Instead it goes to a screen where it is all white with black flashing horizontal lines.
Sometimes a screen will pop up and say simply "You need to restart your computer. Please hold down the power key."
The only thing that I've found that fixes the screen is to take out the battery for 5-10 seconds and then it restarts immediately and perfectly.
I've done my "google" research and found that the early G4's (which mine is) have issues with the logic board and my Mac showed similar symptom's. It also said the "clamp" method temporarily fixes the problem. I tried this and it did nothing but readjust the black flashing lines. It did not fix the problem.
I've tried completely reformatting my hard drive. Starting from scratch. I installed an additional 512 MB of RAM on top of the 256 built-in. I ran Disk Utility to verify and repair permissions. I installed SMART reporter, and it says that my hard drive is fine. I ran ClamXav before reformatting my drive and it found nothing. I can't run it now, it freezes before it's finished every time

Everytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.

I was on the internet with my iBook G4 the system froze for over 10 minutes so i did a hard shutdown of the system (held the power button) When I attempted to turn the computer back on, the start up chime played then showed the grey apple screen, attempted to start up then went to a blue screen and now stays that way. I have attempted to change the PRAM and PMU to no avail, I also restarted in safe mode but all i got there was a different blue screen with no desktop icons.

My beloved iBook 1.33 wont boot, has flashing? and freezes when I try to boot from original CD with a bunch of vertical lines. I ran the diagnostic DVD and it says Invalid memory access. I removed the external ram chip for computer and still get same error. I also zapped PRAM, reset NMVU (whatever it's called). I already have the iBooks case open and willing to try anything.
