OS X :: IMac Screen Black. It Got Stuck In A Loop And Froze.
Jul 30, 2010
I was playing Diablo II and my screen froze, and the same half second blip of sound kept playing over and over. I couldn't even force quit, so I held down the power button until it turned off.
Now, it won't turn on. When I press the power button, there is no chime. Oddly there are an inordinate number of fan wooshes. Like, I hear a woosh from the right, which is normal, but then I hear a woosh from the left, then another in the middle! I am being bombarded with wooshes!I've tried holding alt, or holding shift, or holding alt+s while starting up. No dice, although I do get fewer fan blasts, which is normal.
I received an iMac G5 from this old couple, they were going to throw it out, but all it needed was a power supply which I bought and replaced. It's been about 9 months and everything worked great, no problems whatsoever.Â
Three days ago, I shutdown the computer and when I booted the next day, it would only reach the Apple logo and the spining wheel, the fans would blast loud and then it would shut down and restart again, repeating the same thing over and over. I cannot start it under Safe Mode nor it recognizes the CD when booting.Â
I tried to install Windows 7 via Bootcamp a couple weeks back, but shortly after it failed, I deleted the Bootcamp partition in Bootcamp Assistant. However, whenever I want to boot my computer, it tries to go into the Windows Installation, but it gets stuck on the flashing underscore on the top left of the black screen. Henceforth, whenever I want to boot into OSX, I have to hold down both ALT keys. is there any way of fixing this so the iMac boots STRAIGHT into OSX (like normally)
I just literally updated my macbook pro to the latest version of Lion, today 4/3/12 and now it's just stuck on the main log in page for lion. As in, I type in my password, it thinks for two seconds, goes black, and has the log in page again. It just loops. No end in site. I've rebooted in safe mode, run disk utitily, and repaired the disk... but no dice, still. It repairs the disk, fine right? When I reboot in regular mode, it just goes back to the password/login screen loop.
So my 13" MBP arrived today and unfortunately my first mac experience isn't a pleasant one. The computer wont start. I am hoping I am doing something wrong but I have gone through the step by step troubleshooting and my computer just sits there with a blank black screen. It shows that the charge is full and when I click the power button the little white light glows in front, however, no sound nor no startup happens on the screen.
I was trying to upgrade my girlfriend imac g3 500mhz from os 10.2.8 to 10.3 . The installer soon told me that I needed a firmware upgrade and quit, and restarted the computer. I then got stuck in a bit of a loop and had to use a paperclip to get the disk out. Now when the imac is started, for a couple of seconds a small icon of the os face (?) appears and flashes to a small icon of a folder with a question mark on it (that scared me) but then is seems to start up and run as normal! I've turned the computer on a couple of times now and it does exactly the same thing every time. This flashing image is worrying me, I've given up on the idea of installing os10.3 but have I damaged this IMac?
My G3 keeps repeatedly rebooting. It goes through the loading process, but when it comes time to give you the desktop, it shuts down and restarts all over againl. As it boots up, a double image that you can't read comes up on the monitor, along with a solid color bar that separates the desktop image in two. I have two internal harddrives and changed it to reboot from the second harddrive, thinking that might be the problem. Immediately after doing this, it rebooted fine one time, but now is caught in the reboot loop again. When I startup from the install disk, the image is fine on the screen, as is the startup itself and when I run disk doctor, it says both drives are fine. I homeschool and would like to keep using all of the classic educational software on it for my 5 year old. It's running 9.2.2, 256mb memory 9gig drive is current booting drive, other one is 2gig.
This morning I went to use my laptop, Screensaver passsword box came up and it wouldn't recognise my password at all, So i rebooted. Now my macbook doesn't get any further then the apple logo with the progress wheel then after a while it reboots. So far i've tried the following:
1.)Reset PRAM 2.)Ran Disk Util from install disk and repaired disk permissions 3.) Booted into Safe mode
None of the above have made any difference at all? I thought about "repairing" the install of os x but the version on my disc is older than the version on the laptop so it won't let me?
"When I login, my laptop flashes my desktop background and immediately takes me back to the login screen" Worked late into the night doing things with my laptop it worked fineThis morning when I got into the office I plugged my laptop into my second screen and noticed I only had a desktop on the 2nd screen the laptops screen was stuck on dashboard. (I could create new desktops, etc. on my 2nd screen just fine)I unplugged my secondary monitor and saw my desktop come up on my primary screen.Suddenly another flash and I was logged outNow when I enter the correct password it looks like it is starting to log in, my grey lock screen becomes my factory blue desktopthen it flashes back to the login screenIf I enter the wrong password the input box does the typical left right shake.Â
I accidentally connected my wife's MacBook Air to my docking station at work today. Nothing seemed to happen so I undocked it and the computer displayed a black screen and I could see and move the cursor using the trackpad. I then tried shutting down by holding the power button for 5 seconds, 10 seconds, 1 min, etc. Nothing worked and it's stuck on the black screen so I can't use Yosemite's menu to shut down or restart. When I leave the computer idle for around a minute, the cursor disappears but it will reappear after pressing keys on the keyboard.
I have a Macbook with OS X version 10.5.2. After being prompted to restart my computer while doing software updates, it brought me to a screen telling me to restart my computer. Every time I restart it, it takes me back to this screen, I can't get it to boot!
I installed SL a few days ago and had to rebuild my Time Machine backup. It powered through all 700GB today and then it kept going. The progress bar got to the max: 700/700, then went to 700.02/700.02 ,, 700.03/700.03 ,, 700.04/ 700.04 ,, etc. Currently it's adding onto the "inprogress" file and filling up the drive with more data than I had to backup! It's done 844GB out of 700. Keep in mind, this is a totally-from scratch backup here! Do I stop it? Do I wait until it fills up the drive and "figures it out" ?
This is my first mac, I installed the 10.6.4 update the other day and restarted, since then it has been on or sleeping. I just shut it down and turned it on again and it's asking for my password. Each time I enter it goes to load and then comes back to the log in screen. I know I have the write password because it's a simple 4 digit one that I use for my bank account and if I enter anything else the box shakes and asks me to re-enter it. How do I log in?
My iBook G4, running Tiger, is stuck in a loop. While trying to reinstall os x 10.4 I was instrucked to insert disc 2. So I did. Resulting message: "There were errors installing the software. Please try installing again." with "close" the only option. So I close. It spits out disc 2 and message pops up: "please insert dics 2 to continue installation." The only way out is to crash but there's not really any way out because, when I re-boot I get the "there were errors installing" message and around and around we go. I tried to boot to my hard drive from the install disc but it won't go there. I did the hardware test and it says all is well.
I have a 6 month old iMac (bought Dec 2011). It has 10.6.8 with all patches. It began to randomly shut down and got stuck in the reboot loop (sometimes, the problem was a reawakening after sleep, but even a simple shutdown/restart wouldnt guarantee correct behavior).Â
I did the Apple Hardware Test (it reported - no troubles found), reset the SMC, PRAM - all to no avail.Â
Finally, i reinstalled the OS from the DVD that came along with the iMac. Left it for a few hours to download the "jumbo" patch from apple site, and now it is back to behaving the same way - it is stuck in a reboot loop! I dont know if it installed the patch or not, as soon as i touched any key to wake up the iMac, it rebooted (like before). And now I gotta try the boot process like 15 times and it may boot correctly. Safe Mode boot is also not guaranteed to work. It shows the sliding bar and then back to reboot!Â
If it were a software issue, the reinstall of the OS should have fixed that? If it were a hardware issue, the AHT should have caught that? Am I stuck with a lemon? Just one of those bad pieces that are inevitable in any assembly line production?Â
I just got an iBook g3 used, it had 800mhz, 256 megs of ram, 30 gig, and had osx 10.3.9. I am new to macs, but I particularly wanted an IBook, and I found it used at a good price. I downloaded some software (acquisition) and moved some files over via usb keyboard from a pc. Suddenly, it froze while stuck in screensaver, and I turned the power off. Now, it just stays on a gray screen when booting, and eventually goes black for a second, then reflashes a gray screen. No mouse, no cursor. What do I do?
I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?
I got a 1 TB Western Digital external last night and had left it on all night so that Time Machine could back me up a few times. Then this morning, I had disconnected the drive and decided that I ought to update to 10.5.8 because Software update had told me to the day before. So I did, and I walked out of the room after it started installing the update. Then I walked back in when I first heard the startup chime and the fans were running at 6000 rpm and the screen showed the Apple and the daisy wheel. It proceeded to turn itself off, and repeat the process, always getting stuck at the Apple logo screen. So I tried booting it up in safe mode, but nothing changed; it never got past the apple screen. Then I booted from the install disc and used disk utility to verify the disk and repair the disk permissions. I tried starting it up a couple of times after that and nothing had changed. So I booted from the install disc again and was going to reinstall Leopard, but I decided to restore from one of the pre-10.5.8 Time Machine Backups.
So yesterday I updated a bunch of programs on my macbook via the auto update function. Some of the programs I updated required a restart, which I performed when it prompted me to. Now my macbook won't restart all the way. It turns on and gives the chime then goes to a gray screen with an apple on it. After about a minute a spiral loading image appears underneath the apple and about a minute after that the computer shuts off and immediately restarts again only to do the same thing (its stuck in some sort of cycle). I've tried resetting the PRAM and a few other things but nothing seems to work.
My address book has suddenly gone haywire. It contains nothing 'on this mac' and seems to be stuck in a loop of downloading from iCloud - it gets a few contacts, then more, then yet more, then all, then back to just some and goes through the cycle all over again. Looking at the plist files in the library com.apple.addressbook.plist keeps vanishing and reappearing. I've tried quitting address Book, deleting the plist files (all of them) then reopening, but problem persists. I've tried turning off the iCloud sync for Address Book, whereupon it asks me if I want to keep a local copy: I say yes, but nothing is copied. Turn it on again, it syncs and starts looping all over again.Â
With any movement of the cursor, when playing Youtube and other flash video's, the video's stutter and get stuck in a loop repeating very fast then playing then repeating... I am running 10.6.8 with the latest version of Adobe Flash Player 2GHz Processor and 4GB 667 MHz DDR2 SDRAM.
I ran software update and got (iPhoto, itunes, Security patch) so I ran it and downloaded everything except the Intel Security Patch. So I restarted and decided to try again. Restart didn't work as it got stuck and I had to reach around and restart by holding down the power button. When it came back up, I got the white screen with the grey apple logo and the spinning clock like icon..... spinning and that is where I am stuck, left it off all night and tried it in the morning, same thing.
I did try:
-resetting pram (nothing happened) -restart in safe mode, holding down shift key (nothing, stuck on screen)
I would try to start up from the OSX disk except I have a DVD in the machine. I am thinking it was that security update that didn't download fully that is doing this but how do I get the imac, "unstuck"? or how do I manually eject that DVD to put in a OSX start up disk?
I bought an iMac g4 1.25 17 inch a few days ago, and there is one stuck pixel on the screen, i know not a big deal, but when the display is dark (movies wallpaper) it shows up bluei tried an online pixel fixer, and tried turning off my monitor and applying force with q tip in a cloth, but no diceSo, How do you fix a stuck pixel?
Got me a Second Hand iMac g5 with OSX 10.6 on Screen is black. I changed Power Cable = no Result seen i opened and a thinny Cable from hard drive were not connected. I had to remove the Ram to do that,but no Result i opened again and found another thinny Cable from Broadband Socked comming out. I connected it but nothing happening i opened again with all Leads removed. I removed the Battery inside,pushed after 2 Hour such small Button inside,put Battery in Place,switched on and nothing happened. i pressed the power-Button twice,and on second Time the Screen went White and Fan blow as Hell,but stuck on that. I switched off and on and it was Black again. I disconnected the Lead and switched on after 5 Hour and nothing happens I removed Battery again,pushed after 2 Hour thinny black button inside and nothing when started With nothing happened i always mean "The screen is black",but the Start sound is and i hear a little Fan,and Keyboard reactes with Light on keyboard and with Ping on Computer if i push some Buttons.Mouse has light on Well. seems Screen works. I did not get the Software. It is Snow leopard on but i don't know if re-installing would help or if i need the Pack for 3150.- or what it cost. I also don't know if not Video-Card or logic board fails
I recently upgraded my Imac Harddrive from a standard 320 GB to a 1.5 TB Segate Barracuda 7200 Rpm 3GBS. Previously I had a boot camp partition for windows 7 ultimate. When I put in the new harddrive I decided to start fresh and do clean installs. Now when I try and install Windows 7 it goes fine until the last restart (4 total including initial restart). Then it just gets stuck at the screen where it says "Push any Key to Boot from CD or DVD". It will stay like that for a few seconds then the disk will stop spinning. So my question is now what do I do? I have to have windows for work purposes and this is driving me insane.
I was away at a friend's yesterday and left my computer on and downloading a torrent (I have done this before and everything has been fine). When I came back today, I noticed that my computer was working very slowly so I restarted it. However, it would just stay at the grey screen with the wheel spinning forever instead of moving on to the blue screen.
I know that this has been reported many times before, even on this forum, but everything I tried does not work. I tried:
Holding down Command+S at startup and entering the command fsck -fy. Did not fix the problem Opening the Install Disc and going into Disk Utility. I repaired the permissions and verified that the HD has no problems but the problem persisted.
Going into Safe Mode. This actually works fine, but unfortunately offers an extremely limited functionality of my computer.
I have a few stuck pixels on my screen which i know is inevitable, but I've heard these can be fixed with flashing programs. I came across this and was wondering if anyone has had any success or has any insight on this.
[URL] is the link to the pixel flasher thing. I already tried the pressure technique found here [URL]...an-LCD-Monitor but it didn't work, unless I didn't do it right. I didn't want to press too hard.
I started up my 24" iMac today and it just got stuck on the grey screen before the apple logo appears. I reset the PRAM and I tried using the OSX disc and holding down C. I got to the disk utility and it freezes. I am stuck using my bottom of the line laptop untill I can work around this.
I wish I could take a picture of it, but every picture that I've taken so far has developed into a blurry hue. At, first, I thought the screen was just dirty, until upon closer examination did I discover that this little ******* is an ant. It's stuck between the glass and actual monitor directly below the Safari icon in the dock that I have left at the bottom of the screen. I have a feeling that it crawled in through the speakers on the bottom of the monitor, next to where the ram modules sit. I hope it's not planning to nest and start an entire colony on my i7 8GB iMac! That would suck.
