Why is my 2006 20inch Imac's screen crashing unexpectidly ?
I have a late 2006 20 inch Imac (2,16 Ghz intel core i2 and 2GB of ram and with the Ati Radeon x1600 graphics card)
I have screen black outs from time to time (approximately twice a day) the only possible solution is to hold the power button down and restart the computer .
Other forums tell me it seems to be a graphics card or logic board problem. The crashes are usually different colour flashes and then a complet black screen but the sound carries on and the computer is completely unresponsive. I also have another screen problem when I wake the computer from sleep it stays on for approximately 10 secs then it just goes black again. When i wake it again it just repeats the same problem.
I looked at the logs and there are no signs of any application causing it and when there is one I remove it and the problems just stays and never leaves.
If the problem is the graphics card which is attached to the mother board I have no other solutions but to replace the whole mother board or buy another computer !
Hope there is a solution that is not to costly ! (wallet is not in a good state at the moment )
Hello,
Thanks for the help everyone.
First, i have all my data/files backed up on my older Lacie drives. New ones are still in their boxes.
Second, the noise with the disc. It's not a clicking sound. It's more like the drive is struggling to do something.
It's not continuous, It happens when opening up itunes or iphoto or another app. Or when i try to open up a page on Safari, the page will start to load, the noise will start and either the noise stops and the page loads or the page stalls and the sound continues and then i just hit reload or quit Safari depending on how annoyed i am at the time! It did do this before i updated to SL but it seems to be more and more now!
If i have Safari, iPhoto and Mail open all at once, it's like a battle over what get's done with the sound creaking away and the spinning icon all over the place.
How do i check my drive using Disk Utility? Do i 'verify' it? I have done it before but it was a long time ago.
I never did a clean install. I just put in SL and let it update, then i updated the software to 10.6.8.
I will do that when i get the new RAM however just to start afresh.
I have bought a 2GB Crucial RAM memory (Thanks RadiationMac) but do i need to buy another one now?
Also how would spotlight make noise?
Thank you. These forums are invaluable.

Why does my 2006 Mac Pro 1,1 crash on startup?
Hi, folks--
My 2006 Mac Pro is regularly crashing on startup with a kernel panic. It will chime on startup and usually show me the Apple startup screen with the spinning wheel-- but after that, I get the multi-language "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again" message. Sometimes it doesn't even get there-- the spinning wheel just freezes, and stays frozen. Every once in a while, the Mac will start up, but the mouse will be so unresponsive that it takes me several minutes to mouse over to Restart so I can try again. (I've checked the mouse on another computer and it works fine.)
Additional info:
• I have one SSD startup disk with Lion, and two HDD startup disks with Snow Leopard. Starting up with any of these three disks results in the problems described above. This suggests to me that it's a hardware problem, rather than a problem with a specific startup disk.
• I tried starting up from my Snow Leopard Install disk. It was able to start up successfully. All the data on my hard drives seemed to be intact, including Lion Install, so I tried re-installing Lion on my SSD. It showed the blue progress bar for a minute. Then it said it would restart my computer in 30 seconds-- at which point, I once again got the multi-language "You need to restart your computer. Hold down the Power button ETC" crash. If even the install disk is crashing, this again suggests a hardware problem.
• I set the Mac Pro to target mode, and used it as a startup disk for my wife's Macbook. It functioned just fine and there were no crashes. Again, confirmation that it is a hardware problem with my Mac Pro.
• I have zapped the PRAM. I have also run Disk Utility, repaired permissions, and verified the disk. This did not fix the issue. (Not surprising if it is a hardware problem.)
• HOWEVER: I put in the install disk that came with the computer originally and was able to complete the Hardware Test. I chose the most thorough option. It did not find any problems.
• This started happening three days ago. I'm not aware of any recent changes to the system that could have caused this. The most recent change I made was installing a Radeon HD 5770 graphics card and an SSD drive, more than a month ago. There was no sign of trouble after I installed either of them (except for some problems putting the Mac Pro to sleep, which is apparently a known issue with the Radeon 5770 in this model Mac Pro).
• Weirdly, after I fiddle with the Mac Pro for an hour or so (run diagnostics, reboot it repeatedly, etc) it seems to start working. If there is indeed a hardware problem, then perhaps something works better when it's warmed up.
Is there anything you'd suggest I try? Or am I stuck lugging it to the Genius Bar? I don't have a car, so this is a bit of a pain…
Thanks in advance for any help you can give!Thanks, The Hatter. I'm working through all the links you've provided and see if I can narrow down the problem.
And, Grant, thanks as well-- I really appreciate the specific information. You've enabled me to track down the panic log -- but they are indeed baffling. I'm pasting one below, in case somebody wiser than I can interpret it for me.

Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia 7300
Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia GeForce 7300 GT
I've been suffering with screen tearing, strange screen artifacts, etc. followed by totally unresponsive freezing machine. This problem has been happening to varying degrees for about 9 months.
Initially, I was able to mitigate the problem with smcFanControl. Adjusting the fan speeds up helped keep the machine cool and prevent most of the problems. Recently, we had a spell of hot weather and the fans just couldn't keep up. If you're using smcFanControl, the only fan speed that will really make a difference is the CPU. The HDD and ODD fans are no where near where you need to be.
Also, I noticed the machine was LOADED with dust when I took it apart, including the heat sink fins for the graphics card. If you have time you may want to try a thorough cleaning with compressed air before replacing the card. You just need to get through step 11 below to access what needs to be cleaned.
Based on reading here and elsewhere, I decided to replace the graphics card. To give back to the community, I wanted to layout the procedure here.
Where to buy the card.
I had a tough time finding the right card. I did exhaustive web searches using every combination of Nvidia 7300 GT, etc. You really need to search by the Apple part number. The Apple part number for the 7300 is 661-4179, for the 7600 is 661-4180. I found it at We Love Macs and at dv warehouse. I paid $248 for the 7600 card. BE CAREFUL buying a "refurbished" card. At We Love Macs, "refurbished" means "pulled from a working machine." Could be a machine with as much mileage as yours and prone to the same failures as yours.
The card is an MXM style card (generally used in laptops), with a giant heat sink and heat pipe assembly. The card can be separated from the heat assembly. If I had time, I would have tried a generic, cheaper, MXM style card.
Dispelling some myths.
People here and elsewhere have said that no Intel iMac graphics card can be replaced, that they're wedded to the logic board. The one on this model can be replaced, I've done it. Also, some have said you can't put a 256MB, 7600 GT in a machine that originally had a 128MB, 7300 GT. Also, not true. That's what I did to my machine and it is working fine.
So here's the step-by-step on my take apart and replacement. This is just one user helping out others, PROCEED AT YOUR OWN RISK. This takes about 1 1/2 hours to take apart and 2 to put back together.
1) Install the iStat widget and monitor the temperatures for a few days and record the temperatures (to be able to verify that you've completed the repair correctly later)
2) Make a complete backup of any internal drives and make sure the backup will be bootable (use Carbon Copy Cloner)
3) Use static safeguards, like an anti-static wrist strap.
4) Get a pen a stack of paper envelopes to separate and label the pieces you remove.
5) You'll need a #2 Phillips and #6, 8, 10 Torx. Most of the screws at T-8. There are 8 T-8s holding in the LCD. They are about 1 1/4" down. You'll need a long, skinny T-8 to get to them.
6) Unplug the machine and place it on it's back on a large white sheet of paper.
7) Remove RAM door, #2 Phillips x 2.
8) Remove RAM.
9) Remove 4 T-8s along bottom.
10) Remove large rectangular plastic bezel surrounding the whole machine, tilt up being careful not to stress iSight cables. You'll need to stretch it around the RAM ejection tabs.
11) Detach two iSight cables.
12) Peel up black stickers at lower corners of speakers.
13) Remove LCD screws, T-8 x 8. You'll probably drop a few, they're pretty easy to retrieve.
14) Remove two retaining screws on right hand LCD cable. T-6 x2 Unplug cable.
15) Remove LCD inverter cable, left.
Start unplugging everything connected to the logic board.
16) Unplug cable coming from right speaker. Note cable routing, it is the only one that's a little tricky. Also, note that the left one plugs in on the right and the right one plugs in on the left.
17) Remove right speaker. T-10 Note: left and right speaker screws are different lengths.
18) Unplug ODD blower cable.
19) Unplug ODD temp cable and lift up tape.
20) Unplug HDD blower cable.
21) Unplug the HDD temp cable.
22) Unplug the camera & mic cable.
23) Unscrew the clamp securing the airport card (has two antenna cables going to it, labeled PCIE), T-6 x 2
24) Unplug SATA cable.
25) Unplug Power cable, thick black plastic harness, socket.
26) Unplug ambient temp cable.
27) Unscrew the bluetooth card, T-6 x2.
28) Unplug CPU blower cable.
29) Unplug power button cable, 2 conductor, tiny cable, bottom left.
30) Unscrew left speaker, T-10, unplug from logic board, but just leave dangling, no need to remove cable completely.
31) Remove logic board screws. Be careful to segregate them, they have different lengths and different thread pitches and thread types. Some are machine threads going into metal, some are coarse threads going into plastic.
31a) Heat sink frame to case T-8 x 2
31b) Logic board to case T-8 x 3
31c) Screws at heat sink from arrows T-8 x 3
31d) Logic board at bottom near RAM slot T-8 x 2
32) Unplug ODD ribbon cable, be extremely careful. Release plastic tabs on each side to remove. Be sure it is fully and evenly seated when you put it back later.
33) Remove logic board with attached graphics card.
34) Unplug graphics card heat sink sensor cable at logic board end.
35) Remove graphics card screws 2 x T-6
36) Remove single screw from small L-bracket on heat sink 1 x T-6
Replace graphics card.
Reverse steps, put everything back together. Be careful not to pinch any cables when you put the logic board back in. When you put the LCD back in, if you can't get the screws to stick to the driver, use some glue stick from your kid's art supplies.
Test everything. You've disconnected every cable in the system.
I torture tested the machine with a space heater on it, 5 different videos of different formats playing at the same time. No problems.
I took a lot of pictures inside the machine. As soon as I figure out a good place to post them, I'll try to add a link here.
Good luckGreetings!
I know this is in response to your post from over 2 years ago, but I was searching on Apple's site for the max RAM I can upgrade our refurbed iMac too and it brought up this post.
Oddly enough, I've been experiencing the same screen issues and locking up on our iMac as well. I was concerned it was a bad memory module, but now I'm thinking it's the same issue you found.
Because I bought this some 2+ years ago refurbed from Apple, I'm not surprised that could be the actual problem.
I've pulled this thing apart once to replace the hard-drive which crashed about a year ago, so I'm not totally new at opening it up, but this process you mention sounds pretty intense...just wanted to get your second take on it based on what I've done thus far.
Thanks again for posting this...it was an eye-opener as to what might actually be causing our issues with our trusted Mac!

Does anyone know why when streaming a movie from my iMac the screen on my tele goes grey but I still get audio. It only happens when using the DVD application on the mac. iPhoto streams fine.
You are prevented from Airplay mirroring certain things like DVD content as the material is usually protected so you get a checkerboard type display. I think there is a theoretical risk that the Airplay stream could be intercepted and the protected video copied, albeitin lower quality.
Apple may be being cautious or are required to do so with the DVD player app by movie studios/licensing authorities. It makes no sense to the average consumer who is just trying to send their purchased DVD to the TV via the computer and AppleTV.
Playback in something like VLC should work - not tried it myself but others have commented it doesn't have the restriction. -
Why won't my Intel iMac boot up, either from the internal hard drive or the DVD drive? It just displays a light grey screen, without any other icons, etc. The fact that it won't boot from the original system DVD is what baffles me the most. Any ideas? It uses the latest version of Mavericks. Thanks!
If the C key for Install Disc or R Command for OS X Recovery startup commands are not working, try holding the Option key for the Startup Manager.
see > Startup Manager: How to select a startup volume
If that does not work and you using a wireless keyboard, it may have become unpaired and you need to dig up a USB keyboard to invoke the startup commands.

20inch iMac Constantly adjusting screen
On my 20inch iMac, the display has recently started to go fuzzy and jerk slightly around the screen as if it is being adjusted (press the auto adjust button on a standalone LCD monitor and you'll know what I mean). About half of the screen is fuzzy (not very, just irritating) and it moves about (again reminiscent of the auto adjust feature of LCD monitors) which makes it distracting and hard on the eyes. I wasn't doing anything weird or different when this started to happen, I just noticed that the screen looked a little strange. Also when this happened, my mouse was constantly stuck on right click (not two button) and my keyboard didn't seem to respond to anything. A restart fixed this, but not the screen. It is really annoying, I can't find any solutions anywhere else, and I don't want to take it to the Apple Store. Can someone help me???
Hi and welcome to Discussions,
two things you should try before bringing to the store:
1. Reset SMC: http://docs.info.apple.com/article.html?artnum=303446
2. Reset P-RAM: Restart your iMac and press the Command-Option-P-R key combination during startup.
Hope it helps.
Good Luck

Anyone now why my late 2006 iMac isn't supported for Mountain Lion installation?
My late 2006 iMac was one of the first Intel ones (Core 2 Duo), so does anyone know what about the hardware itself means that Apple don't support it in Mountain Lion?
On the Mountain Lion Tech Spec page it states that Mountain Lion is compatible with the 2007 models onwards. I know they have to stop supporting old devices eventually to be able to progress smoothly but why aren't all Intel iMacs supported?
Just curious really.Mainly the graphics card, which must be only about 1.5 years old max to support many utilities built into ML.
That and the fact that OSX built to be the bestand fastest at some point cannot use very old hardware and CPUs. -
My screen sharing functionality did not show up in the dock with an updated icon. It had a question mark- shows my connections but nothing works, I did make sure screen sharing is on and also connected to VPN. Once I tried to launch screen sharing nothing happens. Such an elegant solution in Mavericks not does not work. Ugh. Help!
This is the post that got me set up- I too am running an older version at work vs. Yosemite. As soon as I followed is advice everything worked.
Upgraded to Yosemite and can no longer remote into my work iMac through screen sharing- it is turned on in settings?
I believe the location of the "Screen Sharing" app has changed, which explains why if you had it in the dock it has been replaced by a ?
Don't forget you can launch screen sharing (once your VPN connection is up) by typing in the Safari destination slot vnc://remotemachinename:portnumber (omit the :port number if you are using the default VNC port, 5900). This should launch Screen Sharing and put its icon in the dock. You can drag the Screen Sharing icon to the left of your dock and it will hopefully remain there after you exit Screen Sharing, or you can right-click on the icon when it's running and select Options->Show in Finder to find out its new location and drag its icon to the permanent entries in your dock.
Hope this helps; worked for me. -
My 2006 24" iMac (6.1) no longer recognizes Tiger 10.4
As I remember, in 2006 this imac had Tiger 10.4 installed when new. Since then, I've done a clean install to Snow Lion 10.6.8. Now when I try to reinstall Tiger I see a dialog box that tells me this computer does not support Tiger! Does anyone know why and how to go back to Tiger?
Thank you Klaus, I suspected as much but wasn't sure. What I want to do is load Tiger onto an external HD so I can see Tiger as I talk my sister through a problem. Besides wiping the boot HD, is there a way to put Tiger on an external drive? Guessing "No"...

IMac black screen when streaming to Appletv
Does anyone have any idea why my 1 year old iMac gives me a black screen when we are watching a movie with our Appletv. Once we stop streaming the movie the iMac will respond again. It is running Lion with all the software updates.
For the unplugging and reconnecting, be sure to follow this procedure precisely.

You should disconnect ALL cables when you do this procedure. When you reconnect the power cord, if you have been using an old or crowded power strip, try connecting it directly to a wall outlet, at least for this test. Power it up with just nothing connected, except for the power cord. -
Why is my Apple Mail's initial screen sometimes changed to half it's regular size?size
why is my Apple Mail's initial screen sometimes changed to half it's regular size? I'm using an iMac PowerPC G4 with OS/X 10.5.8 and Mail 3.6 (936).
It could be remembering where it was when you last quit the program. The Green button in the upper left forces the window to the last adjusted size.

IMac 20" vs iMac 24" : screen WASHED OUT on 20"
I went to two Apple stores and I noticed that the new Aluminum iMac 20" SCREEN CONTRAST is set different from the 24".
I tried using two side by side 20" and 24" and I set the screen settings the same. But not matter what I did the contrast on the 20" was pretty bad. 24" was normal but the 20" was Washed out (when viewing photos, there's no detail in the highlight areas).
Anyone else notice this? Or it just me? I foun this at two stores I went to.GREAT! I thought I'd read all of the down sides to the new 20" iMacs. How'd I miss this? Well, I knew that with the minor CUP speed bump made to the new iMacs and no "Extreme" option on the 20" I was about to take a beating down the road here...very shortly. That "shortly" is already NOW, I guess. My 20" screen was washed out using the iMac's display color setting, so I went into Preferences/Display/Color and played with the RGB profile settings. This helped a lot, but it made me wonder why Apple would have let it be shipped with their poor "iMac" color profile. Geez, I hope changing the setting, making the screen colors pop, won't burn out this monitor!!! GULP!!! If only our old Mac G4 tower hadn't died a few months back, we'd been waiting so long already and a 20" monitor looked big enough to us.
BTW, where are all of my Apple Loops in the preinstalled iLife '08 GarageBand? I just got this iMac yesterday. Time to do more digging!

Why are there lines going across the screen?
Why are there lines going across the screen?
It may (likely) be a video card issue. There is a "known issue" with certain iMacs made in a certain timeframe (2011-12 I think), and one of the telltale symptoms is vertical lines showing up on your display. Go to Apple's website (https://getsupport.apple.com/) to find out how to get support, then either call their service line (they usually pick right up) or take it into your nearest store's Genius Bar. They'll first check if your iMac's serial number is on the list of vulnerable machines, and then they'll have to do a diagnostic to prove that's the problem -- if your serial number's on the list and it fails the diagnostic, they'll replace the video card for free, even if you're not covered by AppleCare (and if you are, it's free regardless).
My iMac just had this problem, there were lines sometimes and just weird display issues other times. Eventually it just grayed out altogether and I couldn't use it. So it's likely your display problems will worsen if you don't get it looked at.
It took them about a week to ship the new video card over, install it, and return the iMac to me.
Good luck!

I lost an entire feature film project in FCPX 10.1.2. Gulp. I was trying to export to Blu Ray, then tried to just export the Blu Ray file to hard drive, i.e., I gave it 2 commands at almost the same time. My fault, but then FCPX started acting funny,
