MacBook :: Boots To Blue Screen Only

Jul 1, 2010

A few days ago my macbook froze, when I did a hard reboot it boots to bluescreen. I've even left it up overnight just in case it was talking awhile.

Here is what I've tried so far:
-boot into safemode, holding in shift does nothing.
-Tried to run disk utility, it said something like it couldn't be done (forgot the exact message)
-reinstall the OS from cd, but holding in c causes it to reboot.
-holding option and clicking the cd to boot from causes a reboot also
-command-option-shift-delete does nothing
-Gone into single user mode done the fsck thing, also tried this [URL]

Starting to think the HDD is shot. Just noticed an error when I type in /sbin/fsck -fy it says "Incorrect block count for file it should be 16 instead of 17. Not sure if that means anything. Was able to run disk utility now, no errors were found however it still will only boot to blue screen.

Mac Pro :: Boots Into Blue Screen?

I tried booting up my Mac Pro, and it boots into a blank blue screen. I tried this several times, but no dice. Cannot boot into safe mode either. This happened about a month ago, and I did another reinstall. When I booted into my Apple Mac OSX Snow Leopard disk to repair, and it said everything was repaired.

MacBook Pro :: Frozen Screen With Pink/Blue Lines?

Sep 3, 2010

My almost 3 year old MBP shows a full screen of artifacts like horizontal lines with blue and pink boxes. It did it while simply browsing the web. It had a message in the center of the screen that said to push the power button to power off in several languages.

I powered off the computer. Tried to restart it and on the start up screen the Apple appears in the center of the screen with the same pink and blue boxes in it and the spinning symbol below is stuck and the computer will not start up.

Any ideas on what my problem is? I have about 2 months of Apple Care left.

OS X :: Won't Boot In Safe Mood / Only Boots To A Blue Screen

Aug 24, 2010

I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this? I am using 10.6.4.

Intel Mac :: Boots, Logs In Then Gives Blank Blue Screen

Feb 8, 2012

I restarted my mac this morning after the time was broken (as far as I know, I cannot manually change it). When it booted, it booted normally. It logged me in (I am automatically logged in) then it threw errors at me. The 2 errors were from Steam and Skype, but none from the mac itself. Steam error: " Steam failed to load: *SteamStartEngine(0xbfffdea4) failed with error 1: Failed create pipe: 28". I forgot to record the skype error, but it was something to do with it not being able to find a file. At this point, the background is blue, I can see the top bar but not the dock. I then close Steam and Skype windows and the bar disappears leaving me with nothing. A blank blue screen. The dock wont come up. 

I would take this to support, but they want a serial code that i cannot access because its not on the hardware and I cant access 'About this Mac" because it disappears.

IMac :: Hang Up On Blue Screen - Only Boots In Safe Mode

Jun 18, 2009

Tried everything from archive and install (wouldn't read disk2 until the 9th try and ended up with 9 system folders). Then tried an Erase and Install. Still it refuses to boot. Get's hung up at the blue screen. Will only boot in safe mode. Now for the last few days even the startup chime is missing. Tried PRAM and NVRAM resets. no help. Won't boot from DiskWarrior boot disk either. Just hangs

Software :: Frozen On Blue Screen / Only Safe Mode Start Up

Dec 8, 2008

My iMac G5 froze. I restarted it manually, but it kept freezing on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM.
Finally I resorted to an Archive & Install. That didn't work so I did a clean install but that didn't help either. After having done everything under the sun to it to get it to work, it will still only start up in safe mode. I even tried starting up off each of my two external fire wire drives with no luck (it froze on the fire wire screen with both drives - a Maxtor and a Western Digital). I am thinking that something on the mother board has died so that normal booting is prevented but safe mode booting is allowed.

IMac (Intel) :: Intermittent Blue Squares That Crashes System

Aug 26, 2014

I'm running a late 2009 iMac, 2.8 GHz Intel Core i7 with 8 GB memory with 27 inch ATI Radeon HD 4850 512 graphics card running 10.9.4 OSX.

I will get spontaneous crash of the system that causes small blue squares over the entire screen. The problem will resolve after 1-2 restarts. I ran the system diagnostic disk and found no problems on the long and short versions. It is an intermittent problem as the display and system are running fine now but daily will have the crash occur. Once the spots are present the computer will be frozen with no response to keys or mouse.

Intel Mac :: Black Squares On Screen?

Mar 25, 2012

Sometimes, when my iMac has been "resting" and I then move the cursor using track pad I get a stream of black squares on the screen. The more I move the cursor the more black squares I get. If I switch off and then on the screen is ok. This is an intermittent occurrence.

MacBook Pro :: 17 Inch Screen Is Pixelated?

Jun 19, 2012

I was using my computer and it was just fine. I closed it carefully (as always) and left for a few minutes. When I came back and opened it up, the screen was completely pixelated. I turned it on and off and read several forums and tried cleaning the drives and nothing is working at all. As I've been working on it parts of the pixelation of bright colors have begun flashing a little bit. Not a lot but a little. Black doesn't seem affected by the pixelation but you can see lines in the white areas. Also when images are fading in and out, they don't become pixelated until they are at their brightest. When they are fading in and out they appear fine.The graphics card in my computer is a Nividia GeForce GT 330M. SO I'm guessing from this that the graphics card is damaged or whatever. I can't afford to have apple repair it for $400 and the nearest apple store to me is two hours away.

IMac :: Not Booting Up/ Crashing With Squares On Screen?

Jul 29, 2010

I have a 10.4 iMac. Recently when using it the screen starts to pixelate with large random squares and effectively makes the computer useless. Either that or I get moving multicoloured flashing squares (very psychodelic)Also on booting up the grey screen with the apple logo has dark grey sqaures and then when it goes to the blue screen has a series of smaller squares top and bootom. The booting up stops at this point.

I have ran the disk doctor, but it doesn't seem to have made any difference.

Mac Pro :: Screen Froze With Digital Artifact Lines And Squares

Mar 9, 2009

Apple delivered a refurb MP. And I just hooked it to my 30" ACD. Then suddenly the screen froze with digital artifact lines and squares. Only way to release it was to do a hard shut-down. And restart. Looks like its the stock standard graphics card. Is there any know probs with the ATI 2600. Also under Graphics/Displays. it just says ATI Radeon HD 2600 (rather than 2600 "XT") guess its the same card. Should I call Apple and get this exchange?

Intel Mac :: 27" Displaying Random Coloured Squares On The Screen?

Jun 11, 2012

How many Mac users have suffered from the problem of small coloured squares appearing at random on the iMac desktop? They can be wiped by dragging a window over them but they will eventually reappear. I have discovered at least three other threads where this issue has been discussed but our local Apple store is claiming that Apple haven't declared it as a legacy fault. It would be interesting to hear how others have been treated when presenting Apple with this fault. At first they thought it was the GPU but they now think that it is either the logic board OR the logic board AND the GPU together!! Being charged between £480 and £650 to repair a machine that is less than 18 months old is a bit much from a company that continually boasts about the quality of its products.

MacBook Pro :: Screen Flickering Magenta / White And Pixelated Image

Jun 12, 2010

I'm having a problem on my mbp screen, although it happened only once just an hour ago. The screen goes flickering magenta and white and some pixelated image. I needed to force shutdown using the power button because it seems to stalled. After restarting, it went to normal. I dunno if it has anything to do with the gfxstatus utility that I've installed the night before. I know it might be the nvidia graphic card itself but I just don't have a clue right now. My MBP is just 8 days old and my 1 to 1 exchange has expired since it covers the 1st 7 days only.

My MBP spec:
MacBook Pro 17" AG, i5 2.53 Ghz, 4gb RAM, 500gb Hitachi HD, 512mb nVidia GT330M video card, Mac OSX 10.6.3, with everything updated. Tthe attached pic is not showing the exact image since the screen was flickering etc and I'm just using a camera photo. I just noticed while I'm just surfing this forum + facebook, my temperature is at 67-70 degree celcius, which is high (normal around 38-45). I look at Activity Monitor and found that Kernel Task is using up to 80% of CPU. I have a feeling that this is not normal, and it had not happened before.

IMac (Intel) :: Multiple Daily Lockup / Green Squares On Screen

Jun 20, 2014

New iMac at first of year has always locked up with green squares (1/4") randomly on the open window.  I have to do a hard boot to unlock the screen.  This may happen 5 or 6 times a day but I'm finding no pattern.  It happens in any software, mail, internet browser, extra programs and only using what I need at the moment, including mail and internet, hasn't worked.  I've run disk utility - repair disk and repair permissions multiple times to no avail.  I've reinstalled the OS Mavericks and Adobe Creative Suite programs (Photoshop & Premiere Pro), no improvement.   

I purchased a high-end iMac specifically to handle high-demand video editing needs.  But this happens when checking email or browsing the internet too.  Here's a listing of the system from a "Panic (system crashes) log" from the "Activity Report." 

System Profile:
Model: iMac14,2, BootROM IM142.0118.B00, 4 processors, Intel Core i7, 3.5 GHz, 32 GB, SMC 2.15f2
Graphics: NVIDIA GeForce GTX 780M, NVIDIA GeForce GTX 780M, PCIe, 4096 MB
Memory Module: BANK 0/DIMM0, 8 GB, DDR3, 1600 MHz,

IMac :: Screen Capture Pixelated Screen At Start Up OSX10.5.4?

Dec 4, 2008

This is the image I get on my iMac 2.4 GHz Intel Core Duo OSX10.5.4. I have repaired permisions and removed all login items. Once I move the cursor or open up a window the screen clears behind the cursor or window etc... It freezes up at least once or twice a day...

I started up again and attached another screen, the image was normal on both screens. But alone the iMac still starts up with the pixelated screen.

OS X :: Macbook Pro Boots With A Black Screen?

Aug 8, 2010

Just about 2 hour ago I put my mac on standby because I had to do some homework, but after I finished my work and opened up my computer, the screen was black. I then resetted the computer by holding the power button down but still nothing.

The computer makes all the sounds like it normally does, it does the chime aswell. However, when I close the computer up the front light isn't pulsating, its just glowing. While my computer's screen is black I can adjust the sound (it makes the noises) and I can adjust the backlit keyboard brightness, but it doesnt respond to trying to light up the desktop. I've tried to shine a light to the desktop but can't see anything.

I've tried looking at some similar posts, tried to reset it up by holding cmd+opt+p+r.. nothing works. I can't understand this... it was working just fine only hours ago

EDIT: after leaving it for 10 minutes, the front light started pulsating as normal again, but when I open it up, black screen still.

PowerPC :: Powerbook G4 Screen Red Pixelated / Screen Going Out?

Jul 8, 2008

I have a G4 Powerbook 1.67 that I don't take anywhere. It just sits on an iCurve as a home computer. Never been dropped, damaged, looks as good as new.

That said, the screen sometimes gives me these red moving pixels which distorts the screen image a bit (pic attached). And lately the screen has been going out at times with lines across the screen, then intermittent blackouts.
