IMac freezing after startup

My 2010 iMac freezes every time I boot it up. I have completely erased the hard drive and started fresh with Snow Leopard, repaired the disk/disk permissions, booted in safe mode, reset the PRAM...I've tried everything to no avail. Within 30 seconds-2 minutes of startup, the spinning beach ball appears and I can't do anything. I guess it's not actually "frozen," as I can still move the mouse and click on things, but they won't actually open. Example: I can click on the apple menu and click about this mac, but it won't open the window. I have been trying to download the Snow Leopard update so that I can install Mavericks to see if that will help, but either the software check stalls or the download stalls within minutes of starting. Any ideas?!

Just to rule out hardware issues, run the AHT.

IMac freeze after startup, works fine in safe mode

Hello, my Mid 2010 iMac is freezing about 3 minutes after startup. Ive tried booting from the instal disk and repairing it but it didnt work. In safe mode it works completely fine. It similar to some other peoples problem but i was hoping someone could help me, my applecare literally just ran out like 3 weeks ago.

Hi baltwo,
Im sorry but Im new to the community and I don't know how to address users directly. Hence intruding.
It would be kind of you to shed some light on the matter.
I'm running lion 10.7.5 and followed similar procedures but mail downloads every mail again after cataloging and indexing my earlier(snow leopard 10.6.5) mail. More details at https://discussions.apple.com/thread/5373643
It would be great to find a solution as I'm struggling since two weeks.
Thanks,

IMac freezes after startup; locks at Login screen

Hi,
I have changed the system date to an ealier date - a day earlier. After a few moments, my computer froze. Restarted my computer but it still freezes at login screen - keyboard doesn't work. The system works on safemode though, but normal startup doesn't work at all. No HW was added or removed except for the external USB drive. I also have tried the following items to no avail:
1) PMU Reset
2) Changed date/time to normal in safemode and installer-disk startup.
3) Disk/folders permissions tests were OK. Terminal disk check was OK.
4) Removed my internet connection and all external disks.
5) Created another user-admin account.
Please help me here. I'm backing up my data files right now and would reinstall my OS later as a last resort.
Thanks.
Ron

Before you wipe your HD and reinstall read this thread http://discussions.apple.com/thread.jspa?messageID=2326655#2326655 Hopefully this will help

My imac freezes after 5 minutes of use

my imac freezes after 5 minutes of use, that's including after i reboot. is there something that i'm not doning because it's freezing on all my programs.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Mac Pro on 10.6.8 freezes after startup

Since updating to 10.6.8 my 2009 MacPro will freeze after startup when opening finder, safari and itunes (so far). No beach ball and ForceQuit doesn't work. Resolved only by a hard shutdown with the off switch and restarting. Never a problem on restart. This problem seems identical to that described in an archived discussion (after an update to 10.5). Refer: https://discussions.apple.com/thread/2018112?threadID=2018112 .
I have followed those suggestions without success:
-run AHT and no issues found
-run disk utility to verify and repair permissions
-used Rember to check memory and no issues
Grateful for any suggestions; thank you.

It means that a third-party system modification you installed is causing the problem.
Reboot as usual (not in safe mode) if you haven't already done so. Don't launch any of your usual applications. Launch the Terminal application, copy or drag -- do not type -- the line of text below into the window, and press return:
kextstat -kl | awk ' !/apple/ { print $6 $7 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Next, do the same thing with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
That's one line, not two. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Next, this command:
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Again, one line. Finally, one more:
ls -1 /Library/{InputManagers,StartupItems}
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal.

Acrobat Reader 9.1.x freezes after startup

Hello,
Our Acrobat Reader is having problems on some machines during startup that it completly freezes after startup.
I've traced this with procmon and have seens that a certain file "sharedEvents" is trying to to somthing buth it is hanging on
lock - unlock. Killing All process of Acrobat Reader and deleting this file and then re-starting the program isn't helping because it keeps 0 kb and the mentioned behaviour is trying to do something with this file.
the file can be found in %appdata%\adobe\acrobat\9.0
Our profile's is redirected , it is working for most of the users but some users are having this problem.
Can anybody tell me what Acrobat Reader is doing with this file and is there a work around to initialize everything back again so the
user can startup the program normally so it is not freezing after startup without having to remove and install it back again ?
Best regards,
Bert

Hi,
The problem I'm having is a problem on the journal file. After some more investigating it look that the problem can be related to oplocks since we have enbaled oplocks on our server (were the file is placed trough folder redirection). We will check this ...
I've already disabled oplocks on client side and then everything is working however we are using Vista in combination with offline files and if you disbale oplocks then offline files will not work so we are looking a bith further to see what we can do on server side ... to be continued ...
Best regards,
Bert

Have run the disk utility and it says disk appears to be ok, Won't startup up in safe boot, blue screen just sit. Have tried 'fsck' fix, just sits at blue screen. Have reset PRAM, I don't know want else to try. Disk utility & "fsck" says 'disk appears to be ok'. When exiting fsck, it will start the process then stops. Does anyone have any suggestions, I have not tried to reinstall 10.5 yet.
Thanks in advance
Paula

After reading resolutions TS1541 & other threads, I decided to try to archive & reinstall 10.5 from install disc. Well that made things worse, sometime during reinstall, system locked up, I looked at the log during install & it had been locked up about 3 hours and now I have nothing. no systems files, using Target( firewire cable) disc with my macbook, I can see I have previous system folder & a folder that say system. but Install disc does not see OS.
Do I need to take it to an apple store for repair or what. It's only 3 years old.
please help

IMac freezing after update to Yosemite

Hi reader!
I'm struggling with my iMac after I've updated to Yosemite.
Problem description:
My iMac keeps crashing when I launch some specific demanding programs.
I tried to launch a game, Heroes of Newerth, it keeps freezing the iMac totally, after 10-15 sec.
When i launch videos on Facebook it does the same.
I can play movies in VLC and i can surf on the internet, but not watch youtube videos.
I’ve tried deleting apps like Adobe and Java, but can’t seem to delete Java to reinstall it.
These apps are being reinstalled as I write this.
The real issue is, it happened suddenly after some weeks after I updated to Yosemite, and i haven't updated anything else the last 2-3 days.
I am really in a pickle, with exam-reading coming up, and I have a lot of stuff backed up on a USB drive, but not it all.
I can't even get diskwarrior before it freezes up.
My specs are
iMac 24-inch, early 2009
Processor 2,93 GHz Intel core 2 duo
Memory 4 gb 1067 MHz DDR3
Graphics ATI Radeon HD 4850 512 MB
If more is needed, I'll be happy to provide it.
Thanks, appreciate the help!

HP Pavilion P7-1225 Desktop Freezes After Startup. Frustrated!

Hi,
My family's HP Pavilion P7-1225 desktop computer freezes a few moments after startup, most times. However, it will occasionally work just fine for hours and then suddenly lock up. Over the weekend a sort of clicking sound was heard followed immediately by the freeze. Restarted a few times, heard noise, got lock up. We're not hearing the noise now but it's still freezing up.
We have yet to talk to HP Support about it, but no other professional has been able to solve it (and we have had many try). Please help!
Thanks in advance,
Leo

Hi Leo,
Many things could be causing your issue. Intermittent freezes can be very difficult to solve. Since so many professionals have already tried to solve your issue then it's probably time to contact HP Support. As such, I am not going to suggest what has probably already been suggested and/or tested.
I don't know if you are using an UPS but transient changes in line voltage (too low or even too high) will often times cause a failover and clicking noises (relay closing and opening) with some UPSs will be heard. I hear clicks from my UPS at times even though the lights don't flicker. A poor or faulty UPS could cause issues like you are experiencing. You might also having an electrican check the circuits in your house. You might want to isolate your PC equipment off circuits that might have high current start up devices that might cause local voltage surges.

My iMac freezes after installation of Mavericks

My iMac set. with the new Mavericks has started freezing, or going into sleep mode, and will not wake up. I have to hold the power button in for about ten seconds to force it to close down, wait a few seconds, the press power button again and it will boot normally.
It will sometimes just freeze the screen, and other times go to a blank screen. Nothing will wake it up.
<Personal Information Edited by Host>

I have had consistent freezes after my MBP (15 in 2.4/2.2 GHz) goes to sleep since I installed Mavericks. When it's frozen, the fan is going hard, but nothing will wake it up -- not mouse motion, key presses (including "force quit" chord), closing and opening lid, etc. I have to force a shutdown with the power button, and restart it.
The only thing I've found to prevent the freeze is to prevent going to sleep. There's nothing that I recognize as suspicious in the console log. I've reinstalled Mavericks, I've fixed permissions, I've repaired the hard drive, I've removed plugins. I don't know what else to try. So I'm looking for suggestions, please!

Imac freezes on startup grey screen and really loud fans

My Imac G5 non intel 20" freezes on startup grey screen and really loud fans start and it won't boot. just have the logo on the grey screen.
I've tried resetting Pram - think that was the right thing to do?
I've tried disk utility, but it won't settle for me to choose the hard drive, it kind of sticks and keeps rotating the wheel.
any ideas anyone?
please help.

Lots of things you can try - first, try resetting the SMU. Next, boot from your install disc, go to Disk Utility and try to verify and repair your hard drive. If that doesn't work, try running the Apple Hardware Test on one of your install discs.
Also, depending on which model you have, you may be eligible for Apple's power supply or video and power issues.
Please post back with results,
Miriam
