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.Â
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.

New to Mac computers. When trying to open computer after being in sleep mode, I clicked the mouse to open the password screen, & a blank blue/black screen appeared & the mouse timer( colored circle) appeared, as if to be waiting. I had to unplug the computer to reboot it. This has happened twice in 2 days.

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.

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 pcscd.pub 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.

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? Â

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.

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

Any ideas as to why my iMac wants to log off constantly. I have it password protected to wake up (purely to keep my kids off) but no other power saver features activated.Whenever I walk away for any period of time, it has tried to log out and may have stalled due to the fact that I've left Safari open or the like, but otherwise logs off completely.

When I turn my computer on nothing happens. You can hear the drive or cooling fans but there is nothing on the screen. Normally there is the spinning wheel but now nothing.

A small (about 1 inch square) blank, white box has appeared at top left-hand corner of my screen. Nothing seems to shift or remove it - cursor doesn't seem to recognise or register on it. I first noticed it soon after I'd had to re-start the Mac (it failed to 'fire up' as usual the other morning), but I can't remember exactly what I was doing when I first saw it.

Recently my iMac display goes black in the middle of using it. Initially I thought it froze up and I had to force it to reboot. But after this happned a couple of times I realized that I could stil hear the hard drive working and my peripheral lights (keyboard, etc) were still on. On a hunch I put it to sleep (Option-Cmd-Eject). After it goes silent I can press a key and the display comes back up and everything is normal (for a while).Â
It's now been doing this regularly for the last 3 weeks. Sometimes three or four times a day this occurs. When the screen goes black nothing seems to work except the sleep-wake thing. I've tried the screen brightness keys too - but that doesn't work either.Â
My software is up to date (Lion 10.7.4). This is a Mid 2010 iMac 27" with 12GB of RAM and the ATI Radeon HD5750.The regular software that I have running is:
Chrome
Forklift
Light-room 4

My Imac has the dreaded blue screen on start up. To avoid this, I unplug the machine each night which solves the problem. I have contacted an Apple service rep who says I need to replace the hard drive. Nothing I have read indicates this. I have not added new hardware, not changed anything. Could it be my hard drive is bad?Â

I'm trying to boot a relatively new intel iMac. I can boot to a blue screen, in which all that happens is the music that happens with the welcome video of mac OS X. Â
I currently have no keyboard to do diagnostics with because I don't have the wireless keyboard that came with the mac, nor a wired keyboard. I'm planning on borrowing a simple wired keyboard to use to diagnose the mac in verbose mode and safe mode etc.Â
The owner of the mac has done a complete reinstall, hence the welcome video music, and that hasn't worked, as the screen shows no sign of anything other than blue.

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.

while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.
