2009 Imac i7 Screen glitchy and freezing (see picture)

My 2009 27" iMac just recently started doing this:
It sometimes is unresponsive, and sometimes the display will start to glitch in this way, but certain functions are still responsive. For example sometimes I can restart the computer through the apple menu, sometimes I can save a file before restarting. Other times the cursor freezes as well and nothing responds. So far restarting the computer has fixed it everytime. It started about two days ago and it's happened about six times. Any thoughts about what this might be? Has anyone seen this before? Any ideas how to check what it is?

Is there a risk of further damage if I delay taking it in? I mean I'll want to get it fixed soon because I want it working properly, but do I need to stop using it in the meantime, or take it in tomorrow or something? Or just as soon as I get a chance in the next few weeks would be fine?

MBP 13" Screen Flickers and Freezes After Upgrading HDD

Hi There,
I have seen on here and a few other forums that people are having issues with graphics cards or overheating that is making the MBP screen flicker and freeze.
Mine has been fine until yesterday when I installed a new Seagte 1tb HDD. It works ok, but every now and then the screen starts to flicker, half of it goes black and the system freezes. Sometimes it's just for a few minutes, but sometimes I need to do a hard reset by holden the power button down for 5 seconds.
Here are the details:
MBP 5,5 13" (2008 I think - Can't remember)
Boot ROM Version:
MBP55.00AC.B03
SMC Version (system):
1.47f2
Version 10.6.8
2.26Ghz Intel Core 2 Duo
8gb 1067 Mhz DDR3 (Just upgraded, but before the hard drive and no issues)
1TB Seagate Momentus SATA HDD
As mentioned, I upgraded the RAM a week or so ago and it has been running fine. I put the new hard drive in last night and after a few hours, the flickering started.
I cloned the hard drive using SuperDuper and it all started up fine.
So far, I have verified and repaired permissions, checked SMART status and run a SMART Utility diagnostic. All comes back ok.
I cleared the PRAM and installed smcfan control as another forum with similar issues said it was a overheating problem and running the fan control program should fix it. I did that at 8am this morning and it has run great all day. Come 5.30pm, the flickering started and then it froze.. GREAT!!!!
It's so frustrating, I was really looking forward to having my MBP upgraded and running fast again.
Any ideas or tips would be very welcome.
Thanks in advance.

set old HD. If problem will gone - you have weakened power supply or internal power converters. Yours new HD draw more power during spinup or something - so voltage on internal bus lowers and memory or videocard freaks.
5.30 PM looks like a time when there begins a lot of load on city energy grid - so voltage in wall socket goes a bit unstable, it may also add to problem.
if problem is gone when you are on battery power - its power supply. If it persists or get worse when on battery - its internal power convertors.

New 27 iMAC keeps crashing iMovie and freezing videos on YouTube & Quicktime

We just got a new Sept 2013 iMac three days ago, purchased refurbished from the Apple Store online. The whole point of the purchase was to be able to use iMovie to thoroughly edit videos for our YouTube channel, use garage band, lots of internet surfing and video watching etc. We spent the extra dollars to get what we thought was the most improved version of the iMac with all the souped up specs in order to avoid any hassle and headaches from a lack of performance. Here's what we have:
3.4GHz quad-core Intel Core i7
27-inch (diagonal) LED-backlit display with IPS technology; 2560-by-1440 resolution
8GB (two 4GB) of 1600MHz DDR3 SDRAM
1TB hard drive (We have only used 80 GBs of it so far, so plenty of space left)
NVIDIA GeForce GTX 775M graphics processor with 2GB of GDDR5 memory
720p Camera & Mic
OS X 10.9
We're feeling a bit duped now as this seems to have turned out to just be a big expensive piece of junk. Here are our problems:
- Firstly, thank goodness that we had our own Logitech HD camera/mic left over from our PC because the "HD camera" built in to the iMac is worse in quality than my old blackberry curve. Grainy, lack luster, mic has sharp and distant sound, really really bad and false advertisement.
- In the middle of using iMovie (iMac came preinstalled with the newest one, i think its 10?), it will stop responding properly or will crash and close, we wont even have any other programs running.
- When opening Quicktime to record a new video, in the middle of a recording or while the recording window is idle, it will start glitching - flashing between live footage and a freeze frame repeatedly. The only way to stop it is to quit out Quicktime and open again and try to record quickly, or in some cases we have to completely restart the iMac, which then still randomly in the middle of a recording or idle window it will continue to flash and glitch. (You can view an example here in the last minute of one of our videos, we tried to make it work and kept the take since we were doing our outro music dance, but it totally ***** when this happens randomly during our content portion and we have to redo recording. http://youtu.be/MAJzaEShJGw?t=4m34s )
- When watching YouTube videos, the computer takes a while to respond to a command, like if we click on a certain part of the video, it will not load it until we press the pause/play button a few times and wait. Also at the beginning of a video it will start glitching and freezing again, similar to how we explained above in the quicktime, but faster.
If you are familiar with what could be the problem or have any advice, PLEASE HELP, we are concerned that after dropping so much money within just 3 days of use, this iMac is not performing flawlessly in the areas that we most needed and want to know if these issues are common and fixable or if its a defect that would require we send this thing back immediately. We did not get apple care and would hate to have wasted money that we really dont have on a glitchy crashing huge piece of junk.
Want to mention a few other pros and cons unrelated to our issues, for those who may be considering buying one too:
PROS:
- The Magic mouse is really great, particularly because of the scrolling and zooming gestures. (Though sometimes i accidentaly swipe in a browser and go back to a previous page losing any information that was input on the page i was originally on, for example, i had to retype this whole apple imac inquiry because i swiped backwards by mistake and the whole form cleared! annoying, wish the horizontal swipe navigated between tabs instead of going through the page view history.)
- When the imovie is not crashing, after watching some tutorials and making a few vids, its a really greatly improved program from the '09 version we used to use. I import and edit videos much faster now, and footage does not freeze or take time to load while im dragging and dropping, it is immediately responsive.
- Love using the Talk to text function (like Siri) by pressing "fn" twice. Use this to write long emails and papers with ease. Would like to see a "Speak" read back option that allows for text to be selected and read back (like Siri on iPad)
CONS:
- The text is SO small everywhere and there is no option to exactly set text size across the whole system, only option given is to set a different resolution which lessens the quality of the screen with pixelation, and some programs give you the option to set custom sized text in their individual preferences.
- Sometimes in both iMovie & Garageband, simple automated functionality will stop working, for example in iMove, when certain screens or images are dragged and dropped to the work area by the activity bar (i dont know what else to call it, the line that rolls across during playback or stays put when pressing spacebar) usually, that screen or image will click into place to align with the activity bar and will highlight the bar yellow to further communicate that alignment before you drop it, but after extended use in a session, that snapping into alignment when adding items stops working. Or sometimes you can drag and drop the ends of a title screen to adjust/trim the clip, but after extended time that too stops responding and does not let the cursor turn into that arrow that allows you to trim or extend, until after many frustrated clicks or a quit and restart.
- When sharing/exporting a video from iMovie, i would recommend unchecking the add to theatre option because it significantly extends the amount of time needed to complete the action and i found out the theatre is just like a video stream of your movies to be shared on icloud for easy access from your other devices (similar to the icloud photostream connected to iPhoto). It takes the time to make the video readily availabe in various sizes on the Mac server for easy access, which means it takes forever for your video to be exported to where you actually want it. This is not something we need and is not worth the wait time. (For example, last ime we left the theatre box checked, the progress status of the video was estimated to be completed in 351 minutes, and then 20 minutes later that somehow inclreased to 385 minutes, then duddenly it was done, so i think this add to theatre option also cause the progress status updates to go berzerk.)

Given the maximum RAM that model can use is 32GB, and the earlier release of that 27" mid-2013 iMac is nearly the same in most regards, you may note the listing of this slightly older iMac 27" is here in an Apple support document...
•iMac: How to remove or install memory:
http://support.apple.com/kb/HT1423
http://support.apple.com/kb/HT1423#1
The images of where the RAM chips are located, behind a metal plate, should be similar in your iMac and the mid-2013 iMac 27" shown in images on that page. Note there are several models discussed.
You could take the computer to a certified Apple service facility (retail store, or specialist reseller) and pay them to do this, and buy the RAM from them, and you will pay for this at a retail level. If they do it, you'd want to be assured the computer did all the things you sought to cure by upgrading RAM, correctly without fault. Like run tests and stuff.... Or there's no reason to not go ahead (after confirming from Apple) that you could buy quality RAM and do this job yourself, citing the Apple page link I'd posted above.
Contact Apple Support:
http://www.apple.com/support/contact/
You'd have to obtain the correct RAM (as indicated in my earlier post, citing MacTracker) of suitable quality for use in a Macintosh computer, and the recommendation for a DIY is to get the kit from 'Other World Computing' OWC online at their site. You can talk to knowledgable sales staff at OWC about what you have and what you need, and to help they may ask for the product serial number.
This is OWC and they have the spec RAM required for your iMac 27" model; double-check info:
http://eshop.macsales.com/shop/memory/iMac/2012_27/DDR3L
Since yours is an Apple Refurbished model it will have a different number series. Unlike those in a retail store, because Apple does that to tell what ones they refurbished; refurbs I bought online were like that.
With questions during the first three months, you can get 'support' under the initial 90-day span of ownership of the new (and certified) Apple refurbs bought online; the other part of that is 'service' for 1 year. Call a nearest retail Apple Store, to set a genius appointment; or go online, and start the process of reporting your issue, while you still have some kind of warranty on the device. They can diagnose the issues you cite and tell you if you can upgrade the RAM (as you likely can) then you can buy and install the RAM yourself and probably pay less than 1/2 the retail rate, if you get some from OWC. A diagnosis is free if the Genius looks into it, but you'd need to set an appointment & lug the iMac to their store; protected from weather/shock.
If you want to extend the complementary service to three years (less the included 90-days) and add two years of AppleCare service, that is an affordable option of about $170. For a total of three years coverage.
{If you had a 21.5-inch iMac the RAM would require a service department visit where they use a different method to install the RAM upgrade. Those are built differently than the 27-inch iMac.}
There is a bit of detailed important information in the Apple link on how to upgrade the iMac RAM. There is a certain amount of RAM installed already and these chips would likely be removed if you get matching sets of new RAM to upgrade the capacity. And no matter what some say, there is a reason why they can be upgraded with more. Even with Mavericks OS X 10.9.x and its 'memory compression' etc, it would gladly accept all the RAM upgrade chips it could swallow. (Behind metal screen, mid-bottom iMac 27")
You may need to consider questions about applications that use system resources separate from those about whatever issues your iMac seems to exhibit. There may be some other cause of the video and iMovie symptoms, but more RAM won't hurt given the beast you bought can use 32GB and it has 8.
And if it seems too much to handle, you have 14 days from date of
purchase to take it back. Contact them ahead of then, if you do.
Hopefully this helps.
Good luck & happy computing!

Screen flashing and freezing

I have a 2008 Mac Pro, which has served me well since I got it, at least until a day or two ago. At that time, it started exhibiting sporadic black flickering on screen, paired with freezing. At first, everything would freeze except the audio, which would continue playing uninterrupted, and after a minute or so the system would unfreeze like nothing happened. Now, though, it seems to have gotten worse; the system doesn't seem to recover after a flickering episode, and even the audio will get stuck into a one second loop after a while.
I tried resetting the PRAM and the SMC. When that didn't work, I tried restarting into Lion Recovery mode with Command-R. For some reason, that sent me right to a reinstall screen, but it didn't matter, because the screen started flickering and the system froze almost immediately after startup. I'm pretty sure that what it froze in was a separate recovery partition, so that should rule out any software issue. I'm guessing that my video card is fried, but I'd like to see what others think; I'd like to avoid buying a video card that I don't need.

2009 Mac Pro 3,1, GeForce 8800GT, 6GB ram.
I have recently had the same problems. Screen flickering, tiling and freezing previous to this video settings I've had for a long time just changed. I am not sure if it is my monitor or graphics card. My graphics card was replaced once already. This is acting a little different this time.
I also reset pram am still running 10.6.8

MacBook Pro screen flickers and freezes after Snow Leopard/Safari 5 updates

Hi guys,
I have a silver 120GB 15-inch MacBook Pro from Summer 2007 with 3GB RAM and 25+GB free space which has recently begun to freeze irrecoverably. The first appearance of these symptoms seems to coincide with my installing the Snow Leopard 10.6.6 update via Software Update.
I'm not particularly well versed in computer technology, but will try to describe my problem as detailedly as possible.
What happens is this:
1. I start the computer as per usual, with only a couple of startup items. Everything's fine.
2. I start working. Use a lot of Safari 5 for browsing websites, often with some kind of Flash or "Flash-type" content such as banner ads, videos, even full Flash designs. I may also have programs such as QuickTime, VLC or an image editor open, if not necessarily "actively" doing anything. Everything's still fine - I'm able to both browse websites and watch videos as usual.
3. After a while of active working - say, 1-3 hours - I notice browsing websites gets a little choppy. Display features such as the file list view in Finder may or may not appear properly. The rotating wait cursor may or may not appear from time to time.
4. Immediately after symptom no. 3, the next time I start to watch a video, either via Safari 5 (say for example something on DailyMotion.com) or a file via QuickTime, something goes wrong.
Following no. 4, one of three things invariably happen:
5a) The video freezes and the entire screen flickers from black to the screen view very quickly two or three times, after which the computer or screen appears to freeze. The cursor still moves, but nothing reacts to it - open windows become completely unresponsive, nor does the top or any other menu react in any way to clicking. The "menu row" of application items, which normally appears when I move the cursor to the very bottom of the screen, doesn't appear. Restarting "blindly" by pressing the Off-button once and pressing R doesn't work. I'm forced to do a hard reboot, after which the computer is once again fine until the next two hours of active working. This usually happens ONLY when I try to watch a video in Full Screen-mode.
5b) I notice the video freezing only just in time, and am able to pause it and "esc" out of Full Screen-mode, and the computer remains operational. However, as soon as I again try to play video in Full Screen-mode, everything described in 5a. happens.
5c) The video stops playing, and the screen reverts momentarily to pale blue before switching to the login screen. I login again with my details, and everything appears to be fine again until the next two hours of active working. The computer "starts up" a lot faster than with a hard reboot. This usually happens ONLY when I've tried to watch a video in its original size, i.e. when not in Full Screen-mode.
This happens 1-4 times a day, and it appears to depend directly on how much work I've been doing on the computer. The less I use it in the course of a day, the longer it takes until the next time it freezes.
So, in a way, I'm able to replicate this problem. 95% of the time the screen has frozen while watching or starting to watch (usually already when starting to watch) video footage, but it has also frozen a couple of times just switching between e.g. Safari 5 and an image editor or browsing a website with a Flash banner ad or embedded video content (which however hasn't necessarily been playing); today, the screen froze when I tried to open a website made entirely with Flash.
Although it could be just a coincidence, I believe this issue first appeared when I updated Snow Leopard to 10.6.6 via Software Update alongside some other pending updates, including as far as I recall one for Safari 5. The update process appeared to have gone well at the time, though, and was not interrupted in any way. I have never had this specific problem with the computer/screen before, though.
I've read a couple of threads here regarding very similar issues with newer MBP models than mine, in which it has been suggested that the fault may lie in a malfunctioning NVIDIA GeForce graphics card. Now I've had that replaced already once because my screen went unexpectedly completely blank after a forced reboot 1-2 years ago (I don't remember exactly), but according to my System Profiler info the card still a GeForce 8600M GT. Can it be failing again?
I've also had some kind of a RAM card failure once. As far as I understood it, one of the RAM cards had fried and was preventing the computer from starting up. I replaced the bad 1GB card with a new 2GB one and the problem was resolved. Before the computer died, there were also other symptoms, but they were not similar to these.
I'm also doing the Apple Hardware Test tomorrow. Any other suggestions, though, than the graphics card?
*Could this have to do with Flash or Safari 5?* Just hear me out. Even though my computer has frozen from watching a video in just QuickTime, Safari 5 has always been open in the background at the same time, and more likely than not with websites with "Flash" content open. And come to think of it, before I performed the Snow Leopard and Safari 5 updates, I used to have daily problems viewing Flash video in Safari 5, the video content either suddenly showing up as "Plug-in Failure" or crashing the browser; I've had both Safari 5 and the Safari 5 Flash plug-in "quit unexpectedly" countless times in the past, almost daily. Sometimes the "Plug-in Failure" could be fixed just by refreshing the browser view; at other times, Safari 5 would stop showing Flash content altogether - Flash banner ads (such as Google ads), YouTube and other Flash videos, everything - until I quit and restarted Safari 5. BUT - since the day I updated everything via Software Update, I don't remember this happening; it never gets to "Plug-in Failure" now. Could it be worth trying to use e.g. just Firefox for a while or is there something (e.g. Adobe Flash) that I could try reinstall? Or am I just clutching at straws here?
Thanks for reading this long, long post!

Do you have access to an Apple Store? If so, it may be worth making an appointment at the genius bar and having them run the test for the NVIDIA problem. Since your replacement logic board still has the NVIDIA GeForce 8600 M GT video chip, it could be starting to happen to your replacement logic board.
I also agree with all of CMCSK's suggestions. Freezing is often associated with hard drive problems. You might also want to run SMART Utility:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It will give you a very comprehensive view of the physical health of your hard drive. If you still have the original one from 2007, it's getting pretty long in the tooth and may be approaching the end of its average useful life of 3-5 years. I just recently had to replace my original 2007 Fujitsu drive.
If your drive is headed south, and is also too small, it may be time to upgrade to a larger and faster drive.
The software update probably didn't cause the problems, but it may have exposed problems that were already in existence.
Good luck!

New hard drive in 2009 iMac has been installed and now I have a folder with a question mark displayed on start up.

I installed a Barracuda 500 gb drive. When I attempted a reinstall based off an external hard drive using time machine, it showed an error message of not being able to complete the back up. This was after I formatted the new drive using disc utility. I reformatted a different external drive and let it make several back ups. I then put the new drive into the machine and now I only get the folder with the question mark. It is a late 2009 iMac. The OS updates have been through the on line store and I do not have back up discs. Everything SHOULD be backed up on my external.

when you partition and format the new bare drive are you running off of an install disc in the optical drive? I have used the install disk for Leopard to access the Disc Utility (did not install Leapard, just used it to access the Disc Utility) as well as the machine prompting me to take action due to the new hard drive being recognized, again using disc utility and using the install disc provided by the hard drive manufacturer. All of these were done according to instruction as previously mentioned, on a reformatted and partitioned drive each time.
What OS version are you nstalling on the bare drive before you attempt to restore from your Time Machine backup? I have not installed any OS on the bare drive. I do not have a copy of Lion 10.7.5 as I purchased it through the app store. I was under the impression I could reinstall all the data through Time Machine but that is proving elusive - frustrating.
Are you trying to use the Time Machine "star wars" interface to restore or are you using Migration Assistant? I am not using migration assistant. I have been using the Time Machine restore application.

Screen scrambles and freezes ipod after update

hey guys, im having some crazy problems with this ipod since the update...the screen kind of scrambles then freezes everything...is anyone else experienceing this and if so how did you fix it if you did at all...sorry if this is a repeat post but im really ****** about the whole thing...any suggestions would be most appreciated...thank you
Josh

I am having the same problem since August 2006. I tried everything everybody suggested, but to no avail. I then sent my 5G video iPod to Apple for repair. They sent it back stating "no trouble found". What a joke! If you go back to the previous version, you can't play music videos anymore, but scramble and freeze problem go away.
No point in talking to Apple tech support. They'll not understand or recognize the problem; they'll just waste your time. I hope some smart guy in this forum will eventually figure out a solution.

iPhone 4 freezes up and changes screens, drops calls, won't hang up

HI!!!
I have an Iphone 4 for 3 years now on and when now I turned on the screen freeze. It doesn't have the screen cracked and it doesn't have any damages of any kind. I did the reset with the home and sleep button and doesn't work. I did the restore process with Itunes and still freeze. I don't find any other different solution to this problem. Is there any other different process that I can do? PLEASE let me know.

IMac gives three beeps and freezes

My neighbour's iMac starts and runs normally most of the time, but periodically when running emits three beeps and then freezes. This is NOT the usual "three beeps at startup" indicating a RAM problem, but whilst the machine is is actually being used.
Can't seem to find anything about this anywhere. Any ideas, anyone?
(The logic board was replaced very soon after purchase as the machine had all sorts of problems . . .)

My imac mid 2010 worked fine with "new" memory for 6 months, then started hanging in mid-session - meaning it froze and beeped loudly hours or days after it booted OK. Put old memory back in and noticed it ran more smoothly with less memory than more. Put the "new" memory back in and ran memtest for days and days; no problems reported. But, the system still froze after I'd been working for a while - at odd times. So, took the "new" memory back to the store, and, while there, upgraded to (more expensive) Crucial brand memory - just to be on the "safer" side. Put the replacement memory in and my imac has never run better - not even when new. So far, my imac is quieter, cooler, and smoother now than since the day I bought it. Thought I'd post this on this old thread because Apple Care had told me to bring the machine to them for three days of testing - per other posts I'd seen on the net. But, that would have been a complete waste of time - since they'd wind up (with the old memory) telling me "no problem," or, (with the "new" memory,) "it's a non-apple part problem." Meanwhile, bad memory can mean bad writes to your hard drive; mine seems fine, but I generally pay close attention to problems and fix them asap, or, sooner. If you wait until you have additional problems, you may spend a lot more time and money getting things finally done - and you may wind up back at "square one" or worse if you trash your drive and it's contents.

Macbookpro screen strobes and freezes

my late 2007 macbook pro suddenly started to strobe (flashed very fast and uncomfortable to the eyes) and the froze. on attempted restart it got as far as the grey gear turning and would stall and freeze. i could not start on the install disc without it strobing and freezing again, so i took it in to apple, payed 79. bench fee and they said they got it started and found some directory problems which they fixed. got it home and hooked everything up and not long after it froze again and would not start. after that i looked at my OSX leopard "missing manual" that i had bought and it suggested a bad usb device or cable. after disconnecting everything, it starts and runs normally. should have read up on it first!

Have you changed anything in regards to Mac OSX, such as installing system updates, updating drivers, etc?
To me, it looks like your GPU may be failing. Since Adobe software utilizes the GPU, that's why you're seeing it with these programs. You should test with other software that utilizes the GPU and see what happens.
