PowerPC :: Load Up The Blue Screen With The Apple Logo, But Then The Screen Goes Black Or Flickers?

Feb 4, 2008

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."

I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

PowerPC :: Alternating Blue Screen With Grey Apple Screen / IBook Updated To 10.5.6

Dec 26, 2008

just installed 10.5.6 on their last gen. iBook.She left the iBook plugged in to the mains and came back to find that the iBook was alternating between the grey Apple screen and a light blue desktop screen where she could see the cursor. Sometimes it would also switch to a blue screen without a cursor.

I've tried holding shift during startup - no effect.
I've tried rebooting NVRAM - no effect.

MacBook :: Black Screen After Apple Logo Boot From OS X Leopard DVD

Dec 3, 2010

Macbook: A1181 Core 2 Duo 2.0ghz 1GB RAM

DVD disk: Leopard 10.5 Retail install

Hard drive: dead (spins with clicks).

With regular startup I get the flashing question mark and can hear the failed hard drive click and spin. After getting the DVD to boot in the drive (it doesn't suck it in right away), I get an apple logo and pinwheel like I should, but after about 30 seconds it goes to a black (blank) screen and the DVD spins down, but not all the way. The computer is still on, but nothing happens.

Oddities:

<>If I start it with an iMac 10.4 DVD I can boot to the install screen just fine, but can't install because it's an iMac DVD. I can erase and partition the drive fine (not the dead one, another one I have).

<>Safe mode boot does the same thing, but takes 20 times as long to boot

<>Retail OSX 10.4 DVD does not boot at all, but that one might be for PowerPC computers. I get the flashing question mark folder.

PowerPC :: Won't Load OS X / Get A Blue Screen With The Spinning Lines

Oct 22, 2006

For the first time ever, my Titanium Powerbook won't load OSX. I was using Excel when the beach ball started spinning. I've had that happen, so I just went to force quit. It wouldn't force quit for me. So I let it sit a while and tried again. Again, it wouldn't force quit. So I tried to Restart the Mac. It restarted, but when it did, I don't see the OSX load screen. I get a blue screen with the spinning lines, but that's it.

Intel Mac :: Won't Start - Get Apple Logo With Spinning Wheel, Question Mark That Disappears And Then Blank Blue Screen?

Jul 1, 2012

My daughter's old I Mac won't start. It is not backed up.  We want to get some things off of it if we can. When we turn it on, we get the Apple logo with spinning wheel for awhile, then a question mark briefly and then a sky blue blank screen.  Is there any hope of getting this to work?  This computer is out of warranty.  Does it seem that if we reinstall the Operating System we might find old data?

PowerPC :: IBook G4 - Blue Screen With Black Box Asking To Restart Computer

Feb 8, 2009

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.

PowerPC :: G4 Showing White Screen And Apple Logo

Jan 21, 2009

I have a Powerbook G4 with me and it doesn't boot up. I am suspecting it is hard disk/ software error that is stopping it from booting up. Here is what I see when I try to power it up: White screen, Apple logo with the round circle with rainbow color. Do you guys think that is is a software error that is stopping it from booting up? The last thing I did was to install Windows Messenger for Mac! I am thinking of trying to do a re-install using the disc that comes with my Powerbook purchase but I am at a lost of what to do. Can anyone please share with me the steps that I need to take? I've got a 'new' hard disk already, please advise on how can I rebuild my Powerbook!

PowerPC :: White Screen With The Apple Logo And Spinning Circle / Large Fan Not Working

Dec 13, 2009

I just acquired a G4 MDD Power Mac. Dual 1 Ghz processors.I pulled the HD out of my older g4, connected it, and powered the machine up. The HD has OSX 10.5 and works fine in the older G4.

The first thing I notice is that the Small fan (in the door) is spinning, but the Large fan under the Power Supply is NOT. The red light on the Motherboard is on.

What happens is that all I get is a white screen, with the Apple Logo, and the spinning circle. it never acceses the hard drive and boots into 10.5 What does this point to? I hope the Dual processors are not the problem here. But that large fan not spinning worries me.

MacBook Pro :: Screen Flickers Black For Short Moment On Switching Graphics

May 9, 2010

I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.

PowerPC :: System Making Loud Noises / Gray Screen With The Apple Logo At Startup

Jul 12, 2006

I have a Rev A 12 inch Powerbook - 867 mHz, 640 RAM, 40 GB hard drive. The machine's always been reliable and has performed great over the years. I bought it the last week of July, 2003.

Yesterday, the Pbook was shut down, and I press the on button so it would boot up. Almost immediately, the hard drive makes a loud, whirring noise. The computer advances to the gray screen with the Apple logo, but it doesn't get past that point and the noise continues, as if it's a car engine that just won't start...

I'm going to take it to my local Apple Store in the morning, and hopefully the data, including my nearly 22 GB of music, can be saved. Any thoughts on how to get my computer working again? By the way, it's the original hard drive installed. Hopefully this is enough info to generate some ideas, I'm stumped.

MacBook Pro :: Grey Screen No Apple Followed By Blue Screen With Vertical Lines?

Nov 30, 2014

grey screen no apple followed by blue screen with vertical lines. Graphics and logic board replaced <6 months ago. What to do? I held down shift, it gets HOT HOT and makes noises. (for safety mode) followed by a blank grey screen and blue screen. Then tried the other way (I think  it's command alt delete? I don't remember) and it turned from grey (no apple symbol) to blue blank. Then third time, grey followed by blue with vertical lines, not blocky clear lines that you can see if you are close to it.

Intel Mac :: IOs Don't Load Still On Blue Screen

Apr 27, 2012

I was using Safari on my iMac, but suddenly started to go slow, with the typical multicolor ball. After this, and because i cannot do anything more with the computer i tried to restart it, but never finished the process.

Finally I restarted the computer manually, but after that appeared a folder with a "question" mark on loading screen. I tried to start the computer on Safe Mode, and was possible. Then I checked the hhd with disk utility and appears ok.Well, i tried again to restart and the computer seems to load IOs, but finaly still on a blue screen with a working wheel apearing at times.

Then i restarted again on safe mode to try to do a new backup (the computer was going well, and i was so stupid to use the backup hdd for another use) but when it's only at 200mb, more or less, time machine says that there is an error and stops.

Info:iMac, Mac OS X (10.6)

PowerPC :: IBook Screen Not Working At Startup / Screen Remains Black

Apr 30, 2007

My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!

MacBook Pro :: Not Booting Up - Blue Then Black Screen Appearing

Jun 19, 2012

I have a MacBook Pro Core 2 Duo 2.5GHz/250GB HDD/2GB RAM that won't turn on, unless I leave the power button pressed, in which case, as you all know, the computer turns off again. It started about 3 days ago. Set the computer to sleep, shut it closed, took it to another room and opened it. The MBP gave me the blue screen, then black and then... nothing.At first I thought it was the HDD, but now I'm having second thoughts. I now think it's the cpu fan.

OS X V10.6 Snow Leopard :: Screen Goes Black Just As The Blue Background Appears?

Apr 26, 2012

I have an iMac 21inch, Late 2009.  I found after it was runing really slow that my hard drive was failing.  It told me there were SMART errors on the drive.  The computer is out of warranty and I'm in the middle of no where so i have no Mac store to take it to.  I bought a new drive, same model, and installed it into the computer.  It turns on fine, but after the Apple logo and spinning coge wheel the screen flashes, shows the blue back ground like its going to load the desktop and then goes black. 

I've tried connecting an external monitor to it and shows up like an extended display.  I've tried connecting it to another Mac, a Mini, and the Mini can boot off the iMacs hard drive just fine.  If it Target Disk mode the Mini and boot the iMac I get the same flash of blue desktop then it goes black.  

This is where it gets weird though, I'm sure your thinking, ok the screen is going bad...  BUT,  I boot off an Ubuntu CD, or the AHT disk and it loads fine and has no turning black.  Its only when booting into the Mac OS or the installation disk.   

One last note is that when its at the black screen and I'm sure its loaded the desktop, if I hold the power button down for about 3-4 seconds, till I hear a click.  I then press the button again right away and the screen flashes on showing me the desktop and everything, for about 2 seconds...

Intel Mac :: Blue Screen With Black Circle In Upper Right Corner

May 13, 2012

My Mac froze. I tried rebooting and now it won't boot past the blue screen. I have a mouse pointer and there is a small black circle with three smaller blue dots inside of it in the upper right hand corner of the screen. Clicking on it does nothing. I tried booting in safe mode but it wouldn't boot past the galaxy screen. Again, I had a mouse pointer but nothing more.I've tried booting from the OS disc that came with the computer. It sounds like the disc is running but nothing ever happens.

MacBook Pro :: Getting Blue / Black Or Gray Screen And Force Shutdown

Aug 29, 2014

Macbook Pro 15 inch

OS X 10.9.4

2.4 GHz Intel Cor i7

4 GB 1333 MHz DDR3 

I have had my macbook pro for just over 2 years. About a week ago it started randomly giving me a blue striped, grey, or black screen. The fan pins up and won't stop and either the laptop shuts itself off or I have to force it off. When it restarts it is very slow and sometimes the fan kicks on and won't stop and the screen just stays white after the initial apple and spinning wheel screen, so I have force shut it down and try again. Other times it eventually loads and lets me in but everything responds slowly and takes some time to open.
