IMac freezes randomly sometimes with pixelated freeze

My iMac is running 10.7.5 from mid 2007, from time to time it will freeze and then I restart it and sometimes it will start up real pixelated and I will have to go through a series of restarts and disk utility verifications and it will work for about a month and come back. I have 210 of 250 mb free. It got real bad a few months ago so I reimaged the machine with the operating disk and that helped for a few months until now. Not sure whats going on, I use this computer to check emails and surf the web I dont do much on it thats why I dont get why I am having issues. Any help would be appreciated.

BDAqua is correct. I found this on the forum:
"If it starts with 4MOT it's a motor (fan) error
If it ends in HDD it relates to the HDD fan, if it ends with CPU it relates to the CPU fan, If it ends with ODD it relates to the ODD (DVD) fan
The number at the end is the actual rpm for the fan.
This error is generated if the actual fan speed is outside the +/- 10% allowance for the target speed."
Check the S.M.A.R.T. status on the HDD in Disk Utility. Even if it states "verified" it doesn't necessarily mean that the drive is in good health. I'd recommend backing up data to another drive via Time Machine or any other app you prefer and replace the one in question. I had an HDD failure on an iBook and the S.M.A.R.T. status showed it was good only for it to fail after a few hours of usage.
Your temps look good. Mine were much higher. The GPU and GPU diode, for example, had temps in the 74C/165F range with SMC installed and running; that's what fried my graphics chipset.
I finally ended up buying a refurbished 2011 21 inch iMac from Apple for under $1000US as per a recommendation from Leo LaPorte.

IMac 24' starts up with Pixelated screen and hangs.

Lately ive been facing problems with my iMac (2009 early model, 3.06 Ghz Intel Core 2 Duo, 4Gb DDR3 RAM). Mostly its during start up. iMac has pixelated screen and the loading wheel also hangs and sometimes the screen also starts blinking. I need to long hold the startup button at the back to reboot, which sometimes works in one reboot and sometimes it takes 3,4 or may be more. Also after starting up, the pop up shows, that computer was not shut down properly. After starting up, iMac has started freexing and pixels start appearing and screen freezes (scheck creenshot below), but I've noticed that even after freezing, I've had the internet on my phone working perfectly fine, which runs via the iMac's wifi sharing.
Can someone please help me solve this issue. The motherboard has been recently replaced due to other problems i was having. What could be causing the start problems ? IS my hard drive crashing or what?
Plese help.

That looks more like a problem with the GPU. You should run the Apple Hardware Test http://support.apple.com/kb/PH11342

New iMac plays iTunes videos with pixels, like snow on a TV

System freezes randomly in Mac OS X Leopard

I have a problem with my system which freezing randomly. When it freezes, I can still move the mouse pointer around, but I can’t move or open any object on the screen.
It doesn’t seem to be connected to a particular program since it might occur in various programs. I checked the hardware and also catalogue structures, authentication and so forth with disc warrior. Another odd thing is that I can’t seem to beable to boot from the installation DVD. I’ve looked in the various logs (for example the crash logs), but there doesn’t seem to be any notation of the freezes on any of the logs. Another thing is that I sometime have trouble starting the computer, pushing the on-button doesn’t result in anything. Is there anything else I might try before reinstalling the system?

IMac (i3 2010) random freezing and now with 3 beeps

Hi I have a 21" iMac i3 base model with 8Gb of Ram (see below).
Ever since I got the mac about 10 months ago it has been randomly freezing up, becoming completely unresponsive to any input (keyboard mice etc), and can only be fixed by a hard reboot (holding down power button).
It can happen while I am away at lunch and I come back to find it frozen on the screen saver. Other times I'm just browsing the web (nb has happens with safari, firefox, and chrome). While others times I have been using the system to its fullest. There never seems to be a reproducible way of triggering it. I can go for a week without issue, and then it can happen 6+ times a day, and they go back to being fine again for awhile. Although it has been getting progressively worse over time and more constant.
I have tried repairing permissions (disk utility and onyx). Defraged the drive (drive genius), run TechTools pro and it passed all the tests. I don't have access to the orginal disks (work iMac) so running the AHT is not possible, as is a clean instal.
I updated to 10.6.8 this week, and now when it freezes, it is now accopained by 3 loud beeps...pause...3 beeps etc etc.
This suggests that it could be a memory problem, but I have never had a problem during the boot up process, and as I said it has passed the memory test on both TechTools6 and Rember, I'm not sure if this is the case.
Because the system completely frezzes, there is no log or error reports created, meaning that pin-pointing the issue or even having proof for the tech-guys/Apple is difficult.
Has anyone got any suggestions on a fix, or how I might be able to get an error report, or how I could induce the problem on que.
Thanks heaps

Ok so it definitely appears to be the RAM. I have found a way to reproduce the crashing....Running Prime95. Its normally takes about 15-30min on the stresstest to get the system to lock up.
But here is the strange thing. It only seems to work if I have the full 8Gb installed.
I have run each 2Gb stick by itself without issues.
And then run 6Gb, changing the empty slot each time, and again no crashing.
I found the following thread also has similar issues, with the RAM the most likely cause.
https://discussions.apple.com/message/15610565#15610565
I can discount USB,wifi,bluetooth as I tried this and still managed to get a crash.
But I did have screen sharing on so I am now testing if I can run the 8Gb with this disabled.
Will report back with my findings.

Two years later, a random, hopeless e9105z PC from Hewlett Packard with continual freezes.

I posted a message over a year ago with no luck, and wanted to see if a second posting would give any advice.
In short, my PC freezes randomly, with no predictability or triggering events. The only thing that happens is the system locks up, the mouse pointer is frozen on the screen, and the system is essential unuseable. All I can do is a hard power down.
Over the 100+ freezes I've had, here are some odd things that have happened:
(1) Around 30% of the time, pressing F8 to run system diagnostics fixes the problem. When I run system diagnostics, 90% of the time, the system comes back perfectly clean.
(2) Of the times that systems diagnostics has been run, here are the errors that have been found:
--several times, it warned me that my Western Digital 640GB HDD was about to fail
--two times, it warned me that I had no boot path
--two times, it warned me that my Intel X-25M SSD was on the fritz
(3) Sometimes I can turn back on and be okay, other times, I have gotten something to the extent of 'boot sector missing, press Ctrl-Alt-Del to reset'
(4) system has been unplugged/replugged several times, motherboard dusted off, SATA connectors unplugged/replugged, etc.
(5) the system sometimes will fully boot up in Safe Mode, other times it just freezes up during the initialization. when it does hang in Safe Mode, it does not get hung up on the same file twice.
(6) For Windows Update, the NVIDIA nForce Serial ATA Controller June 2009 driver update crashes my system. I have to do a system restore. This update is hidden/disabled in the Windows Update profile
Recently the freezes are happening once every 1-3 minutes every time I turn on. They used to go once every 2 months, then maybe once every 2 weeks. Tonight, oddly enough, my computer has worked for over an hour without problem.
HP's tech support has been useless. It seems like they are more or less following a flow chart that has little applicability to this situation. Telling me that my printer and Microsoft keyboard were the problems. (Really? Am I that stupid?) They succeeded in gringing me down over the phone. And besides, I'm out of warranty.
Is this most likely a bad motherboard, or an NVIDIA chipset bug, or a Windows 7 compatibility issue? I have no idea where to start (or end) in this problem.
My configuration:
Win7 clean install
6GB memory (Stock)
Phenom II X4 945 (stock)
Intel X-25M primary/boot
Western Digital 640GB HDD (stock)
Microsoft mouse
Microsoft keyboard
A printer that is hooked up about 30% of the time (Lexmark X8350 POS)
Any help is appreciated.
Thanks,

I am having a similar issue with random freezes/hangs as many posts with my Pavilion Elite m9350f that I bought a year ago or so. I have automatic update turned on and have gone to HP and MSFT sites to ensure all drivers/software are current. I have also attempted to clear the fan and heat sinks of lint.
This has been a chronic issue since the PC was new that has good days and bad. On good days I will not see a crash at all. Bad days, the PC will randomly hang every 5 minutes or so EVEN when cold, while in BIOS setup, and operating in safe mode. The software applications I use don’t seem to be relevant (they are limited to Office Pro 2010 and StarCraft II). The typical “crash” is a hang that freezes the display and all user I/O. USB ports will often power down (laser mouse light will often turn off as does PS2 keyboard). I also don’t hear the buzz of the hard drive (it appears to spin down). I do hear the fans even after a hang. A power cycle is needed to reboot and bring the PC back online.
The ‘crashes” seem to corrupt data on the HD. As a workaround to fixing this issue, I reinstalled/repaired Vista several times because as time from install increased, it seemed bad days became more prevalent. Then, three months ago, because the PC crashed too hard to reload/repair vista, I installed Windows 7 and replaced the hard drive. When I attempted to attach the faulty hard drive as a secondary drive, my PC would not boot (faulty drive was confirmed?).
Now with the new OS and HD, I am seeing the same problem again. Like you I am running out of ideas. I took the PC in for troubleshooting with the GeekSquad where they kept it for a week (three days longer than planned) to run several virus scans and hardware diagnosis programs. All test passed. The tech claimed to not duplicate a crash so I thought maybe it was my keyboard and mouse. I bought new keyboard and mouse on the way out of the shop. When I got home, the hangs continued…another bad day. The event log recorded several crashes while the PC was in the shop…I hate being told lies.
My PC Event viewer logs close to 50,000 events most of which mean absolutely nothing to me. I am unable to find events that appear prior to the 41 and 6008 recovery error notices that might signal a cause. However, I am getting many instances of Event ID 12 with indicates “The platform firmware has corrupted memory across the previous system power transition. Please check for updated firmware for your system.” I assume this means to look for an update to motherboard BIOS? I am working on finding the right BIOS now. I don’t believe it likely a BIOS update will fix the hang issue.
Reading through the forums, I see this issue on many different PC models configured with many variants of software. Like you I don’t have my PC working correctly yet. Maybe we just need to accept that we bought a lemon and start replacing parts? I’m thinking power supply and motherboard…

Imac 10.9.3 freezes randomly

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.

There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent of each. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
☞ If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
☞ Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

PowerMac G5 Dual 2GHz freezes any time, boots sometimes with one processor

Since two weeks I experience freezes at different up-and-runnng time. It could happen at grey startup screen (after a while fan goes wild), could be after some minutes working in a full booted user environment.
I run AHT several times, no error reported. When I took out all RAM except for Apple RAM, it still freezes at some time.
Now, by random, my machine starts sometime with only one processor and is stable for hours (only the fan runs higher and cpu load is most of the time near 100 percent). Activity shows one bar only, System Info says: Number of CPUs=1. I have no idea which processor runs and which "sleeps" deadly. iStat tells only about CPU A as having a temperature, the fans of CPU A run higher, but the fans of CPU B run also on a lower level.
The "U3 Heatsink" reads 65-70 degree Celsius. Is that (too) high?
Only once I got a kernel panic during verbose startup. It read:
"System failure: cpu=1; code =00000001 (corrupt stack)
unalined fram address: 0x00000001"
I am tempted to shut down one CPU with Open Firmware command, but will it be the defect one? At least the machine is doing something regular then, but is slow...
Any help is much welcome!
Yours, Whoopy

My PowerMac G5 Dual 2.0 also has this problem.
It all started one sad afternoon a month or so ago. I noticed that my computer was on and the fans were on full speed. As soon as I moved the mouse to shut it down, I got the wheel of death!
I had no choice but to do a force shutdown.
The next day, I turn my computer on and it just stayed on the gray screen with the dark gray apple, and no spinning thingy.
So once again, I had to force shutdown.
Pressing the 'Option' key did gave me the screen where one can select where to boot from; the main HD, booting CD, etc. but none of the worked.
When I chose to boot from my internal HD or from the restore CD it would just get stuck on the gray screen with the apple logo.
I pressed the PMU button = no change
I did a PRAM reset = it brought my G5 to life but then a few minutes later it froze and history repeated itself.
Did a PRAM reset again and this time didn't work.
Tried booting from my PowerBook G4 HD via firewire = frozen gray screen
When I pressed the 'T', i get the FireWire logo and I'm able to boot my G5's HD using my PowerBook G4. But when I put my G4 on firewire mode and try to boot my G5 by selecting the OS of the G4, I still get the frozen screen, so the problem is not with the HD.
One time I was able to boot my G5 from the 'Restoration CD' and I used the Utilities to Fix permisions, and repair the HD but still the computer would freeze and same old story.
Since I got this problem, It has work normal only 3 occasions but no longer than an hour until the fans go crazy and freezes.
I tried different memory sticks and no improvement.
My AppleCare expired on May, and my G5 went down 2 or 3 months after that.
This feels part of an strategy called "Get a(nother) Mac". Where comps are design to last just a little after AppleCare expires and then BOOM! no choice but to spend some serious cash on fixing it or use that money plus more to get one of the resent mac which have had some changes since one bought the mac that just went to apple heaven.
Anyways, I feel that the problem will be solved by replacing the two processors, heatsinks, or whatever they called it.
I took apart my G5 today and I'm not sure but it seems that the heatsinks might use some kind of gas to cools the CPUs or Chips and I think that gas is over.
Has anyone swap the heatsink units and noticed any difference?
Here's of the heatsink for the PPC G5 2.0

This forum is for people to discuss issues with other users. Apple aren't here. No one here can give you your money back. So, contact the the App Store support, if that's where you bought it. There's a link on the right hand side of the App Store window.

Safari, Camino freezing randomly across sites with great frequency.

All internet totally functioning, ichat, mail, streaming video etc.
But for some reason Safari is freezing randomly - some websites load fine,
others freeze halfway through or don;t even being to load.
I tried Camino - but the same problem happens so it isn' Safari specific.
I've dumped the cache, plist etc and restarted and repaired permissions to no avail.
Anyone know what the problem could be? It's sort of come out of the blue over the past couple of weeks and I'd REALLY like to fix it!

this is happening to me too. I am on an intel iMac, and it is happening in Safari, and also in Camino and Shiira to a lesser extent.

My imac screen works fine but it keeps flikering and freezing whats wrong with it

my imac screen works fine but it keeps flikering and freezing whats wrong with it? theres no crack or problem with it it just freeze's ande flikers

It sounds as if your graphics chip (on the logic board) is failing. The other answer could be that your screen is not well, but I lean more towards the graphics chip. If you have Apple care or are still under warranty, call Apple.

Imac keeps freezing Problem started with Snow Leopard

After I loaded in Snow Leopard, my Imac began to have beach balls and freeze ups. Then I loaded in Lion hopeing it would help but it
seems worse with constant freeze ups. I had the compauter in for a tune up at a Mac store but it was good for a few days, but now
it seems to happen more often. I dumped Flip for Mac thinking this was causing the conflict to no avail. I have run the utility program
and it did not come up with problems

Revert to Snow Leopard and solve your SBBOD issues. Upgrading never fixes underlying issues. See http://www.thexlab.com/faqs/sbbod.html for more details.
