Mac Pro :: System Freezes For Few Seconds / Strange Blue Screen With Flashes Appear
Oct 5, 2008
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.
recently my mac pro has been randomly freezing then all 3 of my screens go blue for 5 seconds, then everything is back to normal. This happened 2 months ago, and eventually my graphic card died. I dont know whats causing this, I have tried different cards so i no its not hardware. Anyone have this happen? Any fixes?
ive had a look around an only found bits an pieces relating to this but nothing really specific.i have an imac 3.06ghz, 4gb memory. less than a year old its been making some noises recently (like a downloading sound for afew seconds every so often) which happens every 30 seconds or so. this happens even when theres no programs open and im not connected to the internet!!! ive only really noticed it doing this the last month or so to be honest.
the computer has also been re-formated about a month ago as it was passed onto me from a family member, an im wondering if its got anything to do with that?is this a normal thing for macs an maybe i just havent noticed it before, or does it sound like something is wrong??
I just hooked up a 2nd monitor to my early '08 Mac Pro and when in OSX the screens start to go blank/blue for about 1 second intervals. They flash together sometimes, and other times sort of independantly to each other. When the desktop comes back on it fades in like its animated rather than like its cutting in and out.
It seems fine when I disconnect one monitor.Running 10.5.2 all updates 8 core 2.8ghz with 10gb ram and 8800GT
I was using my mac pro 3.2 octo from 2009 without any troubles. Recently it started giving non stop trouble. I have 2 gb ram from the factory and another 2 from 3rd party. My problem is when I boot my mac I am getting some strange vague designs and it freezes. I tried shifting the boot hard disk from slot 1 to slot 2, booting with either set of ram, changing the graphic card slot etc.
My MacBook was working perfectly until a couple days ago, when it suddenly started hanging every time I booted it up. I gave it a day, and managed to complete some software updates the next time I logged in, after which it started working fine again. Now, however, it KEEPS freezing every ten seconds no matter what I'm doing. The worst part is, it freezes for about five seconds (the pointer becomes a pinwheel, which keeps rotating, as if my laptop's processing something), and then it starts working again. I ran a virus scan to no avail, and have rebooted my MacBook countless times. I don't know what's wrong with my laptop
So my Macbook pro started to stall for 10 seconds or so every few minutes beginning yesterday. Like I am just surfing the net, and it freezes completely for 10 seconds, than everything is back to normal. I don't know what to do to remedy the problem. I have Applecare so I could send it in, but wondering first if anyone has had this problem and knows a quick fix before I send it in.
I am facing weird problem of screeing going BLUE every five second. I tried checking Hardware using hardware test DVD and it found no issues. Additionally, I verified both the partitions along with permissions verification using DiskUtility. But, the problem is not going. Finally, when i tried to reinstall the OS by inserting Mac OS X Install DVD and pressing 'C', the DVD is being rejected.

I have a mid-2010 Macbook Pro with a 2.53 GHz Core i5 processor and 8 GB of RAM, running OS X 10.10.1. For the last few weeks, at apparently-random intervals, the machine has been rebooting while I've been using it. I can't tie this to anything in particular that I'm doing. It may go a couple of days before a restart, or it could be like today, where it's happened five times in the last four hours. I've tried resetting the PRAM and the SMC without apparent effect.Â
When the reboot happens, the system first freezes for roughly 30 seconds--the mouse pointer won't move, it's unresponsive to keyboard input, etc. The system then appears to power down--the screen and external monitor go dark, fans stop, keyboard backlight goes out. A few seconds later, it powers up, gives the boot chime, and goes through the normal boot sequence. At no point does it give the "your computer was restarted because of a problem" message, and I don't see anything in the Console app that looks like a kernel panic.Â
About two years ago, the logic board was replaced to address a somewhat-similar issue--the system had been freezing and could only be recovered by a hard power off (holding down the power button for several seconds). Â
I'm not sure where to start looking for the cause of this problem, since I can't figure out anything in common with the circumstances surrounding the reboots.

its a PC and i know this is a mac only forum but i dont have the time to sign up for another forum. anyways, i boot the pc, it brings me to a menu where it has the options to boot in safe mode, boot normally, etc. i choose boot windows normally and it starts to load windows, however, it freezes about 5-10 seconds into the loading screen and it brings me back to the same boot menu. idk what to do!
After windows is installed a Blue screen appears with cursor on screen but it freezes completely.I can fix this by restarting my mac , then once windows restarts i insert the Mac OS disc , select the disc within my computer but the following message appears "Package requires new version of installer"
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.
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 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.
I've currently got a 3rd party WiFi network in my house and I've set the AirPort Express to join the network to act as an ethernet bridge. My VOIP phone connects straight to ethernet so that's what I have connected currently to the ethernet port on the AirPort Express.
Now it all seemed to work fine, but when I actually use the VOIP phone the connection seems to go dead for around 4 seconds on a regular routine of about every 10 minutes. I'm not getting disconnected or anything but it just goes silent. I noticed that whenever the connection does this the Airport Express switches from solid green to flashing amber for the dead period then back to green again.
Also, any idea how I can access the Airport express now that it's joined to my other network? Airport Utility can't find it since I've done that.
I was just surfing the net and suddenly my macbook pro 13 got frozen with a loud "beep" every few seconds (the same sound as that of upgrade booting). What happened? I've shut down and then it restarted as usual.

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 iMac 27 and screen problem on start up i have blue vertical lines, when it start i have a lot of blue dots and nothing else. when I connect outside monitor its showing the same.
Just installed lion and still the same problem when it starts blue dots, when startup in safe mode loads of blue lines and dots on the screen.
I have recently bought a 13" Macbook Pro and wanted to hook up an external display (an oldish acer 19"). I have a Mini Displayport to DVI adapter hooked up to a DVI -VGA adapter which leads to the display. I haven't got it to work yet. I have followed advice about closing the lid and using usb mouse and keyboard with no luck. The only thing that happens is that the screen on the laptop flashes blue for about a second after plugging in the Mini DisplayPort adapter.
just using my new MBP today and twice when turning it on it started to boot up and got as far as the blue screen (just before the desktop pic and stayed there.Is this normal sometimes?
I have a 27" iMac and an LG 47" 1080p HDTV. I just bought the Griffin Video Display Converter, which is certified by Apple to pass both video and audio from the mini display port on the late 2009 iMacs. Whenever somebody turns on the HDTV the iMac's screen flickers the color blue on and off, sometimes staying that way permanently. Permanently the color blue that is. The only way to get out of it is to turn the iMac off and then back on (restarting it).I have the ?Mirror Displays? checkbox checked in the ?Display Preferences?. When I uncheck that box it treats the connected HDTV as an extension to the iMac display, whether the HDTV is on or off, which makes my cursor disappear off one side of the screen. This is why I leave mirroring on.
I have been having a problem that is not application-specific, and not Lion specific. This only happens on my 2009 iMac 24 running Lion 10.7.4. (I also run Lion on my 2011 MBP and have not had this problem.) It doesn't matter whether I'm in iTunes, Safari, Logic, Pages... running applications alone or in combination.It doesn't happen right away. It's usually after I've been active on the computer for at least an hour. I will try to describe it the best way I can:
1. I could be browsing Safari, for instance. I'll notice that a small section of my desktop starts "growing" red, green, and/or blue pixels. If left untouched, the pixels overtake about 70% of the display until the computer freezes. Now, if i click anywhere on my screen -- in Safari or on the desktop -- whatever the mouse is pointing at will redraw itself. Meanwhile, the screen starts blinking rapidly and basically, has a tantrumI can't Force Quit, Restart, Shut Down, or any other activity. The only solution is to power it down using the power switch.
2. I'm working on music in Logic Pro. When I have Logic running, it usually spans the entire display. Within the Logic screen I'll see a small section of these red, green, and/or blue pixels. (Well by now, I know what's coming so I immediately save my work before the system freezes.) I quit out of Logic, but the pixels continue to take over my desktop. If left on it's own it starts going berserk as described above. Eventually the system freezes and I have to power down
This started happening last month. Two things happend last month: (a) I switched my internet service and combined my internet connection with my land line. I had previously been using a dedicated line for internet. (b) My service agreement expired on the iMac... go figure!
My PowerBook G4 has been slowly dieing over the last couple of month, ever since I told it was going to get replaced with a MacBook Pro early next year (hopefully around MacWorld). The Airport signal is slowly decreasing and I'm in the same room as the wireless router, the mouse touchpad in parts is loosing sensitivity, there are randomly hard freezes of the system, etc.
But over the last couple of days I have noticed a strange noise coming from the fan (well that's guess), it sounds like its sighing, I know it sound ridiculous but it's the only thing it reminds me off. It comes and goes (the sighing) but it is constant and it's really starting to: 1) Freak me out that my computer could die and day, 2) Annoy me. I have a sound clip (.amr - also converted to .mov) does anyone know how i can upload it onto here or a link, so people can hear what I'm experiencing.
I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?
The first time I connected to my HDTV using a mini displayport-dvi and a dvi-hdmi adapter, it worked flawlessly. Stupidly, I set my TV to a resolution it couldn't support. Now the screen only turns blue until System Preferences eventually crashes and the TV gets no signal.
I've tried clearing my PRAM, deleting the profile in the colorsync folder, and even deleting /Library/Preferences/com.apple.windowserver.plist out of desperation. I've confirmed that it's not a problem with the adapters by successfully getting another HDTV to work. Where could could OS X be storing the display's settings?
