I have an older imac and after installing a mac update I was required to reboot after install.
It froze at the beginning of start up at the apple logo. The spinning icon is the only indication on the screen as if it was working on loading. There is noise from the imac as if it is starting up but nothing happens.
I have let it run hoping it would eventually start. But nothing.
IMAC DV400 is the model number.
I have a nice clamshell 300 mhz that worked fine, yesterday I tried to install an extreme airport card and now it doesn't start anymore. The power receptacle goes from green to orange in seconds and the computer appears dead, may be I pushed too much the card inside breaking something or may be I should have removed the battery (that is not working anyway), I don't know, what do you think I should do now? May be the logic board is gone?
View 11 Replies View RelatedSometime ago, I installed MAC OSX Tiger 10.4 onto my E Mac (CPU Power PC G4.1.1). It functioned OK for a couple of years, but then began freezing.
We tried to re-install the OSX system from an external DVD drive and although it registered the Install DVD, it would never boot from it. Eventually, we used my son's Mac laptop as a slave and reinstalled.Unfortunately, the computer still freezes randomly. It seems worse when pulling things from the dock (eg: Word files, Firefox etc.) or when pull down menus appear.
I have a G5 iMac - 2.1 ghz, 20", 250gb hd and 3gb ram, but it has been having problems starting up and it is also going to sleep midway through a task or at random times totally unprompted.
It now almost never starts up first time (I keep the iMac mains power lead always connected and the mains electricity supply turned on at all times now)- sometimes I will get the 'Start-up Chime' and then the cooling fans start spinning very loudly and then after a few seconds the iMac stops the start-up routine, but often when I try to start-up I don't even get the 'Start-up Chime' and I have to leave it for some time before trying again.
I can also now only get the iMac to run as a Firewire Target Disc by starting up with the T key held down and then using an old G4 (400mhz) Powerbook Titanium as the screen/keyboard by using the iMac HD as the startup disc for the Powerbook but this is obviously just a temporary work around.
I have also tried backing up all my data, and reinstalling the Mac OS X onto the iMac but the iMac still will not start-up normal and I still have to use it just as a Firewire HD.
my g5 imac wil show the start light, so I know it works, it won't gong or start up!

did a quick search on Apple, and here but didn't turn up much of anything useful. I've got a friend with an iMac that won't boot up. Pressing the power button doesn't seem to do much of anything. I've tried unplugging the power cord, and re-plugging it, but alas, I got the fan to rev up for a second and then blahh, nothing again. It's a 20" model with the black bezel. Not entirely sure of the system specs, I only got a couple minutes with it last night. Do these machines have any common problems like this?

I got my new 24" iMac ~2 weeks ago, and it's AMAZING compared to my MB... Except the fact that the computer will randomly wake up or start up in the middle of the night. The first night I had it home, it turned on 7 times! The next night, it did it once and I turned it off. It stayed off. The day after that, I turned it off when I went to bed. At 4 AM I hear "DONG!!!!!!!!" Ugh. I get up, and turn it off, only to have it start up at 5 AM. x_x I spent the next day looking for answers, I turned off wake for ethernet network something, and turned off screen sharing, quit all programs, and turned off the Airport card. Still, at 3 AM, it wakes me up. I turn put my jacket over it so I can get some sleep. I've been fighting it every night. I'm tired of it. Yesterday I reset the SMC and PRAM, and it still woke from sleep.

When I start my iMac, a few programs start along with the computer. I don't want any programs starting by default. I have reviewed the Preferences of these programs, and see nothing to uncheck regarding auto startup. And I don't see anything related to this in System Preferences. How I can start the computer without programs starting with it?

View 1 Replies View RelatedI just installed Windows 7 on my 27" i5 iMac, and it was working fine until just now. It froze completely (I could move the mouse around) for a minute, and then it unfroze.
I kept using it, and then it froze again, but this time I had to restart by holding down the power button. It just happened again, and I had to restart again.
The only thing I have running is Chrome, and this is a fresh install. What's going on?
I turned my iMac on today and it starts up to the blue screen with the welcome screen but the loading bar doesn't load at all and it just freezes. Nothing has changed between today and yesterday
View 1 Replies View Relatedhas all my art course work on. When pressing the power button there is no start up, screen stays black. There is a noise from the Disc Drive, when you put your ear close you can hear the Disc spinning, occasionally it starts to make a loader noise like its trying to spin to full speed maybe, but stops before it can. Green light can be seen from bottom, tried unplugging and waiting, tried pressing the cmd R-P keys down at start up. Also tried as suggested on the apple website to use a paper clip to manually eject the disc.
View 6 Replies View RelatedI just got back home and I move my iMac's mouse to turn the screen back on. It turns back on and I notice the whole computer is frozen except for the mouse pointer (the dock wont zoom or anything). I hold the back power button to force it to shut down, but the machinery inside doesn't quite seem 100% settled yet, I can just barely hear a little fan moving, but then it too stops. Upon turning it back on with the backbutton, it makes a clicking sound over and over again (sounds like it could be the HD?)
It keeps making this sound then pauses, and does it again. It freezes on the white screen where the grey apple would usually appear. It's stuck on this white screen and keeps clicking, until I'm forced to shut it off from the back again. I've tried shutting it down from the back, then unplugging the power, but that hasn't done anything either. I'm using... Vista. (the specs of the iMac are in my sig.)
Upon starting My Intel iMac, it stops at the Apple logo. I have restarted it several times and tried to hold down the "r" key while starting to enter the restore mode...nothing but the Apple logo. OSX 10.7.5
View 8 Replies View RelatedI have a problem with my iMac which is running OSX 10.8.5. I think the easiest way to explain this would be to just give a simple example. For example let's say I have Excel and Word both open. I shut them both down. Then I completely shut down my computer. Power off. I go to bed. Next morning I boot up and guess what? Word and Excel are now running again, just as if I had never shut them them down.

So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.

My 2014 21" iMac powers itself down after about 10 seconds while trying to startup in safe boot mode. I'm not even sure why it is trying to start in safe boot mode. I shut it down after a power outage while plugged into an APS UPS. I'm guessing that since I interrupted the auto shutdown it is restarting in safe boot mode. Either way, I get a grey screen with a big apple and a progress bar. The progress bar gets to about a tenth full and the power just shuts off.Â
I've tried starting up while holding the alt key to select the Macintosh HD. The same thing happens.

View 10 Replies View RelatedI purchased a 24" iMac in fall of '07 and up until have had no problems at all. Let me describe the problems I'm having now and maybe someone can tell me what to do to remedy them.
A couple weeks ago it started freezing randomly. The mouse will switch to the beach ball and just spins endlessly. I can move it around but can't really do anything other than that. I have to do a hard reset to get it back to normal. Sometimes a couple programs are open, and sometimes none. It seems like it happens often when I quick switch from one user to another. It will switch, work for awhile, then freeze.
Now, no big deal, annoying, but whatever. But, the other day after doing a hard reset it revolted into a white screen with a flashing folder with a question mark. I did some research and found that I needed to repair the startup disc using the snow leopard disc. I did that and it allowed me to boot it back up normaly but didn't really solve the freeze up issue.
So, that just happened again, so I'll have to boot it up with the disc again and repair the startup disc when I get a chance. It's really beyond frustrating now.
I have repaired all permissions, updated all firmware, made sure the drive isn't full, pretty much everything short of backing up and wiping the drive and reinstalling the OS. Is that what I need ro do now? I mean, I know I need to, but is there something I can do to remedy until I can get around to doing that?
I have an old iMac Rev A (or B?) and it is constantly freezing. It freezes in OS 8, 9, and 10.3.. but most frustrating is that it also freezes while trying to install an OS. So right now it does not have an OS installed because of that. It will not boot up to my OS 9.1 disc.. but it will boot up to it's original 8.5 disc and a 10.3 disc.. However it always freezes near the beginning of the install process (often before it even writes to the HDD). I tried taking out the old RAM and leaving it with just the one (new) 256MB chip and that didn't work.
It was freezing before with only the old RAM so. I guess it's not the RAM. I have an identical iMac that doesn't choke on anything (never freezes) and it only has 96MB of RAM. I don't know what else I can do. I'm trying to use XPostFacto to put 10.4 on this thing (it's possible, I want to try it out at least) but it won't get through the first OS install and if it does, it won't get through the second (10.4). Even more frustrating is that I don't have any diagnostic software such as the Apple Hardware Test because the original iMac didn't come with any.
Is anyone else having the problem with iTunes 8 where your iMac freezes completely (only the mouse will move but you can't click anything)? I started having this problem after upgrading to 10.5.5 and iTunes 8.0.1.

I need your opinions; since the 10.6.3 update my iMac has begun to freeze to a blank screen. I think this may be a sign of a dying logic board, however I question this as I don't have the freezing problem with 10.6.2. Picture of blank screen attached.
