2009 iMac Blue lines and crashing - Apple replaced graphics card but same problem occurs? Any advice?
Hi all,
So Ive had my iMac 2009 model for a fair few years, and barring getting the hard drive replaced a while part as part of their program, no troubles. Then a month or less ago, I got this weird crash during work. Small cubes of vertical blue lines appeared all over the display and froze everything. The arrow cursor still moved but had to hard reset. Then it would just constantly freeze and the blue cubes appeared again on startup so I could only get in using Safe Mode.
After browsing the web, I heard a backup restore might fix it, which it seemed to, but then it kicked in again. Took it to Apple who could see no hardware issues and the problem didnt occur while I was there because of the restore, it was more intermittent. So I took it home and it happened again.
This time at the Apple Store, they told me it was definitely the graphics card and took it in for repair. Service was great and a few days later I get it back, pay for the repair and come home. All fine and no problem for a couple weeks.
Yesterday it kicks in again! Same problem, cant boot at all outside of Safe Mode, which is erratic, has 5 columns of blue lines across the screen and Mail flickers like ****.
Ive booked it in AGAIN at my local store to check, but my question is does anyone have experience of what this could be, and also if the first repair was wrongly diagnosed and didnt fix the problem, will Apple refund that, or offset it against the actual repair if something else needs replacing?
Any help or insight would be greatly appreciated, all the best!

new card or not, I guess only Apple themselve will know, but Apple Authorised Service Centre can only replace with original card. you may consider to get your fan replaced too, as your iMac is getting old now and the fan might be getting weak to cool your system down.
well, this is only a suggestion. I've been an IT technician for years, and I do encountered graphic card keeps failing till we changed the fan, just sharing my experience.

please help me with dis...
I am using iphone 4..32 gb...i hav updated to ios6..i am experiencing serious lags...watever m doin d phone lags n goes to the home screen...frequency is much greater..please help me with it...i even replaced my device but same problem on new one..!!!!Restore the phone as a new device. There is probably something that was corrupted on your phone during the update and has been passed via the backup to the replacement phone. If the corruption/problem is contained in the backup, you'll need to re-sync your data, and re-install your apps manually. Restoring the backup again will only bring the problem back with it.
If restoring it as new does not fix it, then make an appointment at the genius bar. -
I'm getting an error message "There was an error when opening this document. Access denied" on some PDF's that I was able to open in past. Uninstalled XI and installed X but same problem. How can I access these files?
I have exactly the same problem. The interesting thing is that the file opens when I attach it to an email and open it out of the email. I already saw the advice you provided in similar post from Aug last year and checked the security settings of the file and the folder. But according to that I have all rights.
My OS is Windows 7 Enterprise. -
HT3964 my imac 27 display has 5 blue lines and does not boot up what is the problem?
My Imac 27 displays 5 blue vertical lines and does not boot up. What could cause this?
I already anticipated the video card causing this issue. This was confirmed today by Apple issuing a campaign indicating the AMD Radeon 6970M video cards are defectivce and will be replaced free of charge three years from date of purchase. I looked at the new iMacs and found repairing them to be a nightmare. So, once this p.o.s. is repaired, I'm selling it and purchasing an ABA computer.

I have a 24" imac model 9,1 running OS 10.6.8 and I am experiencing frequent freezes and crashes. How can I solve this problem?
HalAs old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.
Here is a link to a Widget to monitor your temps and other operations:

since you are running 10.6.8 did you install the combo update?
Mac OS X 10.6.8 Update Combo v1.1
It is more stable than the regular version.
You could use your original install disc and boot from the disc, run Disc Utility and do a repair disk. -
I dropped my iphone and the screen has blue lines on it. Siri still works but the screen doesn't but the screen isn't cracked or shattered. What should I do?
Bring your phone and $199 to the Apple store for an out of warranty exchange of your phone. You clearly broke it when you dropped it.

My imac won't startup past the spinning gear and my apple keyboard is wireless but it won't connect, how do I fix the problem so I can get into safe mode?
Can anybody help me on this issue? I have already tried to replace the batteries but since the computer won't get past the spinning wheel of death then the keyboard won't connect.Please follow Apple's advice in http://support.apple.com/kb/TS2570. If you need to get your hands on a wired USB keyboard, even a PC one will work fine.
Do not follow the previous poster's advice, that option is a "last chance" option. OS X is stable and in most cases a reinstall is never needed. Follow the directions in Apple's letter. -
f i have a mid 2009 mac book pro and an apple tv that is the latest one. i can not mirror the mac book on my tv. is it the fact that my computer is a little older than 2011 models which will work. any info is greatly appreciated
chuck schickYes. You need 2011 or later in order to mirror as it requires the newer processor. The alternative is airparrot, which does it via software.

My iMac boots up fine and the mouse appears to be working fine however nothing responds to the mouse click. I took it to the Apple store today and they checked and repaired the permissions. I brought it home and still have the same problem. Does anyone have any ideas?
Hi, thanks for trying to help!
I just blew out the dust and turned it on again to the same problem.
So I tried holding the shift key which did something but then on reboot I got the same problem but this time worse, see here...
So I tried the alt key but that just gave me two startup disk options, both of which didn't work (they led to the same problem).
Then I tried CMD+s and followed your instructions, see below...
I just held the power button down and turned it on again and the same problem happened again.
Any further thoughts?
Thanks!

I have an iphone 4 and it's not working, if i pay can apple replace it with the same model even though it's no longer for sale?
If the iPhone has not been opened or serviced by other than Apple
or authoriized service provider (there are a few other requirements),
you should be eligible for out of warranty replacemement for $149 US.
Apple maintains sufficient stock for replacements even for iPhones that
are no longer available for purchase. You may be better off upgrading to
a newer version than paying $149 to stay with the iPhone 4.
What is no longer working? If you provide more details as to the problem
and what troubleshooting steps you have taken, some one may offer
a solution. -
I found some little black dots n my iPhone 5 screen. I've only had it for 2 weeks. What are they and will apple replace my iPhone for a new one or fix it?
They should have one in Stock, but you never know. Call your Apple Store and tell them you have an iPhone 5 color and GB, and that you most likely will need a replacement, do they have any in Stock. If yes, go in, if not ask for advice on how to handle your problem.

Where can I find the System Mac 9 that would be in the (original release) factory shipped iMac's prior to 2010? I'm missing key system data and cannot update to iPhoto app past 6.0.6; any advice will be helpful, thank you.
Where can I find the System Mac 9 that would be in the (original release) factory shipped iMac's prior to 2010?
What are you refering to here? Mac OS 9 came out around 2001 ( or about ). Mac OS 9 last run in an emulation mode in 10.4.11 -- Tiger. Mac OS 9 ran on PPC machines that were last produced before 2004 or so.
I think your conclusion you need Mac OS 9 is incorrect.
I'm missing key system data and cannot update to iPhoto app past 6.0.6; any advice will be helpful, thank you.
iPhoto '11, Mac OS X (10.6.8), need to upgrade system to 10.8
We need to verify some information. Are you really running 10.6.8? What hardware?
Here is how to find out what version of Mac OS you are running:
Click on the blue apple in the upper left hand of the screen.
click on this icon
Click on the first line, "About This Mac"
Most of these are numbers & that's what we want.
What version & Processor do you have? -

IMac with bootcamp and parallel boots into windows 7 but won't boot into Mac OS lion?
Hi,
Thanks for your suggestion. Actually that was not the problem, because I had the Mcintosh drive set as my boot drive. The answer was that my Lion Os got somehow corrupted and I had to reinstalll Lion. This was all after I discussed the situation with the Apple Support people.
