I7 iMac Processes Freezing and Computer Locking

Hi everyone,
I'm using an iMac i7 with 8GB RAM, but it's intermittently pausing and eventually locking up hard.
On a fresh reboot, I get a couple hours work, then the machine starts pausing, eventually locking up. The processes are active for about 15 seconds, then freeze for the same amount of time. In Activity Monitor the active processes (e.g. Finder, Terminal, Safari, Activity Monitor, etc.) appear as "Not responding" during the frozen period (unless Activity Monitor is also frozen, which it often is).
According to iStats and `top`, I've got 6GB of RAM free, and the CPU usage is generally 0-1% (i.e. idle). No processes are using any measurable amount of CPU or RAM.
When I reboot and run the 'D' hardware tests, no problem is discovered.
According to iStats, the computer's temperature seems fine (HD: 52°C, CPU: 46°C, ambient: 23°C, GPU diode: 59°C, GPU heatsink: 58°C, memory controller: 51°C, power supply: 64°C), as do fan speeds (optical drive: 999rpm, hard drive: 1125rpm, CPU: 937rpm).
As a matter of interest, this started happening two days ago after the computer locked up while playing Starcraft 2 and I had to hard-reboot. At the time I was (and still am) running 10.6.4; I'd installed the Snow Leopard Graphics Update on August 31st.
I'd be very much obliged for any thoughts and input, as - unless I'm mistaken about the hardware somehow - the usual suspects aren't appearing (i.e. a rogue process, overheating, broken fan, etc.).
If I were to guess, I'd suspect a problem with the scheduler, but I don't know that much about Darwin to test.
Thank you kindly for any thoughts and suggestions.
Brian

Hi, when I had that type of issue on my C2D the HD was the cause..
You could have either the Apple Genius's or your local Apple Approved Service Agent take a look & run some tests..Their testing programs are more vigorous than techtool... Have you rebooted holding down the D key, (D=Diagnostics)? it has 2 levels, try them both...L

Can't update from 10.0.0 to 10.2.8 as screen freezes and computer locks up

Can't update to 10.2.8 as screen freezes and computer locks up when using Pref/view/update/10.2.8 100 meg combo update. I have to wipe disk and reinstall 10.2.0
I can't find a stand alone combo that works with 10.2.0 - indeed I can not find any update for 10.2.0. I do find discussions of the 10.2.1 and 10.2.2 updates, and once one has 10.2.2 there is a combo to get to 10.2.8.
What is the solution - by the way I like 10.2.0 better than prior 9.2.2, and do not mind having to wipe disk and lose 9.2.2. But my wavelan 16 bit wireless PCMIA card, indeed any airport card, no longer is recognized. Indeed I can't find Airport. This is a 10 year old computer and files/docs etc are long gone (but life was good until I decided to move to X this month). How do I correct this lack of wireless (it does connect directly to my Ethernet line so getting on the web is no problem)?

Hello papau. Welcome to Apple Discussions.
You could try the 10.2.6 combo as that will install on 10.2
http://docs.info.apple.com/article.html?artnum=70174
and then 10.2.8 which requires 10.2.6 can be downloaded here.
http://www.apple.com/support/downloads/macosxupdate_.html
Run Repair Permissions in Disk Utility, found in Applications/Utilities/ before you start and once again when you finish.
During the installation process, just wait till the system completes things and not use any other applications until the update is finished.

My computer is slow, freezes, and often locks-up. What to do?

HP Pavilion Elite HPE
No matter what we do our computer is slow, freezes, and often locks-up.
We use system Mechanic, defraging, and windows security essentials but nothing works. Please help

DO not try to use things like "Double my speed. com". First thing is you didn't state how old you PC is. Have you tried clearing/deleting all history and temp files from ALL user accounts? Next, what type of anti virus do you have? Norton, just about every version is known to slow your PC, but not to the extent of causing major frustration and they do have a start up manager which allows you to run only certain programs at start up, and will only let them run when requested by you. How much memory do you have? This is always a big factor, you may need to install more memory. I think your problem is in the memory capacity, clear out and delete files/folders not in use and you may also want to delete programs that are rarely used or programs that you may not know are installed in your PC by some download you may have performed. You also might want to look at what process are running (you might have high cpu usage) and disable what is not necessary Hope this helps.

Everytime I open an app on my Imac the colored wheel spins and computer locks up without opening what I want.

Everytime I open an app on my Imac the colored wheel spins and computer locks up without opening what I want. I can't get past my initial screen saver screen. Can't even go to Apple/AboutThis Mac... color wheel just starts and doesn't stop.

Care to share which OS you are using?

How do I get an iMac to automatically restart when screen freezes and computer has to be restarted at plug

Occasionally the screen on the Imac will freeze and the compute has to be restarted at the plug, but when the plug is switched back on the computer only switches back on fully with the screen coming on if you switch a button around the back of the computer, but I remember when using an iMac G4 it would come on automatically when th computer was switched on at the plug. Is there any setting or any software that will automatically restart the computer when the computer is off and I restart it at the plug?

You cannot, what you need to do is find out why your computer is freezing. Perhaps you can shed some light by posting an EtreCheck report and we can see how your system is configured and look for any obvious red flags. You can get EtreCheck by clicking http://www.etresoft.com/etrecheck

My iMac screen freezes and a grey colour slowly creeps down my screen

Hi, my iMac screen freezes and a grey colour slowly creeps down the screen and has a large black square in the centre saying "You must restart your computer by pressing the power button and then pressing it again to restart" or words to that effect in English and about 4 or 5 other languages. I find this happens more frequently when I try to stream movies or tv shows. It also happened when I was trying to download a couple of tv shows from iTunes.
It also sometimes makes a wierd sound a kind of loud noise like a record stuck in a groove. This has happend many times since upgrading to Lion. I hear a lot of people on here talking about their screens going completely black and not responding. I believe that mine has only gone black a couple of times and I couldn't wake it up from "sleep mode" with the mouse or keyboard. I don't know if this is also happening to other people, but my bluetooth keyboard keeps disconnecting all the time since the upgrade as well, it's driving me nuts!! Plus my wifi will show that it is fully operational, however, I can't use the internet when I wake my computer from sleep mode. I have to click on wifi and turn wifi off then on again before i can use it.
Is Apple going to come out with a fix or are we going to eternally suffer indefinitley.

Hi Eric,
I don't know why it didn't work before, but here is the most recent errol log. It crashed again about an hour later. If there is a solution, i would greatly appreciate knowing what it is because I can't enjoy using my computer anymore because of these constant crasahes.
Thanks for your time.

IMAC is freezing and shutting down without explanation

My IMAC is freezing and shutting down without explanation . Any thoughts or suggestions? Could this mean the motherboard is about to die? I have considered erasing the hard drive and reloading, but I'm unsure if that will help i.e. if I back up my IMAC using time machine, then I am just relaoding the problem when I use time machine to reaload........ Thanks!!!

Any thoughts and thanks for the reply.
Disconnect all peripherals from your computer and try -
<a href=http://support.apple.com/kb/HT1411 or http://docs.info.apple.com/article.html?artnum=2238
You can also cross post over in the Intel iMac area regarding your motherboard concerns. Users who use the same model computer as yourself would know.

IMac was freezing and now wont start?

My iMac was running a little slow the past 2 days, and whenever i tried to type something in safari it would bring up the loading wheel and take forever just to type something. I installed google chrome and it kept happening so it's not safari. Next my mac started freezing and i would have to just turn it off and restart it. Turning it back on it would load sometimes but take awhile, sometimes it wouldnt load so i'd turn it off and try again until it worked.
now when i turn it on the gray/white screen comes up with the apple, but no loading thing comes up under that. after a few minutes the apple gets replaced with a circle with a line through it. After about 5 minutes of not starting, a blinking folder with a question mark starts flashing and it does this until i turn off the computer.
soooo, what is wrong? how do i fix this? is there another way to start the computer?

i put in my snow leopard install disk and then restarted using my internal hard drive and it worked fine for a few hours. Then it crashed again and now it's doing it again and cant find my internal hard drive. I have most my stuff stored on an external hard drive but does this mean i have to buy a new computer? or a new internal hard drive? how much would that be and for them to install it? stupid macs, i thought they were supposed to work better than PC's. Or is your hypothesis wrong since it did start up after you said it was dead.
It does sound like your hard drive is failing and needs to be replaced. Mac hard drives are the same products as they are in PCs and they ALL fail, on average a HD should last 3-5 years however some last months and some last 6-8 years. So there isn't any reason to be angry at Apple. Make sure you are backed up and make an appointment at your local Apple Store or AASP. A replacement hard drive will probably run in the $200-$300 range including labor.

IMAC screen freezes and goes blue....

this just started yesterday - I did not add any programs or update any software recently. I have since added Norton and scanned for viruses.
PROBLEM: my system freezes and the screen goes blue. It does not "wake" back up right away and after it goes blue a few times, it stays blue and I have to hard boot. If I leave the system off for about an hour, I'll get a few hours out of it before this happens.
DIAG: As stated above, I checked for viruses. I also ran all available diagnostics, and am fresh out of new ideas. Since I can't open my iMac without voiding the warrantee, I can't check for any possible burst or bulging capacitors. I disconnected all perperials and still have the same issue.
HYPOTHESIS: I am heavily leaning toward a hardware problem, but before I take the trip to the Apple store, I wanted to reach out to the forum to see if anyone else has had this problem?
This is an early 2006 Intel based 20" iMac that I have been running (24x7) since late August 2006. I never had an issue with my first iMac (pre-Intel).
HELP!!!
intel IMAC 20" Mac OS X (10.4.8)

silentpartner,
Unless your issues match a known problem, (wouldn't appear too likely if no result from the Apple Hardware Test) before Apple will accept your iMac for hardware repairs, you'll have to prove it's not a software issue by reinstalling the OS. FWIW, if it's a hardware issue and in particular if the hard drive needs replacing, you'll want to back up your important data anyway, prior to turning it in for any repair.

I just installed mac osx snow leopard in my iMac. windows freeze and unfreezes.

Help needed again. I just installed mac os x snow leopard on my imac. sometimes when I open a window it freezes and then suddenly unfreezes until the next time. the tool bar does not identify what program is opened when frozen. It says finder instead
Thanks for everyones help. It has made a huge difference. I hope this is the end of my issues with this new OS.

Have you run Software Update several times to ensure you've picked up all available updates after upgrading to Snow Leopard?

Track pad freezes and phone locks up

Why does the track pad freeze and then the phone locks up? It takes over 24 hours for it to reset.

That isnot normal. How much free memory do you have? look in Options and te "memory" in the search bar. Look for the number next to Application Memory.
Also, do you have any 3rd party applications installed?

Display goes blank and computer locks up

I have the P205D-S7802. When we close the lid, a password is required when it's opened. It usually comes right awake for us, but after it's been awake for awhile, the screen will go blank and the computer will lock up. We have to power it down the hard way and power it back on. It's usually okay until the lid gets closed and opened the next time...
I've also tried to set a screen saver several times, but it never seems to take effect.
Help.
Please.

Maybe a BIOS upgrade is needed?

Good luck!

Screen goes blank and computer locks up

I have a model P205D-S7438 that will randomly go blank and none of the buttons will work. (Num. lock, caps lock, etc) This lap top is less than a year old. It has been doing this since I've had it. Does anyone have any suggestions?

IMac G5 Freezing and mouse inoperable

iMac G5 frequently freezes where I am not able to click on anything. The mouse arrow will move around but I get no response when trying to click on anything.
Also, at times the mouse arrow will dissapear when I'm moving it around. Are these two problems connected?
I've already tried moving the mouse usb from the keyboard to the back of monitor. That doesn't help. Also I've noticed when it's frozen, the time and day is not on the top right corner.

Continuing from the other thread...
Try an SMU reset. if you have the Rev B (ALS) or iSight G5 model see this link:

If you have the original Rev A G5 model see this link:
