Old iMac won't start.

Hi all

My old iMac (core duo Intel) refuses to start, even after her trying everything I could find on this forum.

Safe mode barely fills one third of the status bar before leaving. Apple Hardware Test says the disc works perfectly, as do the Single User Mode and my old eMac using a method of fire wire cable and hard target disk. I have reset NVRAM and controller management system without result; and verbose mode isn't anything say. I do know that if it means something but after all these procedures a blue cursor arrow appears in the upper left corner of the screen. I tried to use the disk utility on the OS x install disc, but the computer crashes with a message box indicating that I have to restart my computer – so it seems there is no way for to reinstall me OSX either!

Can someone please suggest a solution until I have to take it to a service center for what will be probably an expensive repair? If I think I know what you responses will be!

Thank you very much.

When you run the Apple Hardware Test, do you have it run Mode Extended 2 - 3 times back to back. Except if you did the test you ran was worthless. AHT is unreliable, the reason to run in Extended Mode is to allow him to test all components, even then he captures errors sometimes until the third attempt. However, when errors are found, they are accurate.

Given the age of the computer, you must decide if you want to invest in it. If it is longer than about 6 years, Apple won't touch which means to take at an Apple authorized Service provider who can charge for diagnosis. Your call is really what you want to do.

  • 2015 iMac won't start - help me make sense of this code?

    Last night, my iMac went to the screen "your computer is restarted due to a problem".  Then the Apple logo appeared and he began to start, but then I got the tour of the code to the bottom of my screen.  There's only a few seconds, it was therefore difficult to analyse.  And it tends to be a little different each time.  But it's the chain I've been able to freeze:

  • 2011 21 inch iMac won't start after the SSD upgrade

    Recently, I upgraded my hard drive for an SSD via a computer repair business in my neighborhood, I also upgraded the ram, but I don't think it's in the case. On a two weeks after the upgrade, my computer don't turn on more. I took it to the genius bar and they told me that the DSS had "failed." So of course, I took my computer to the computer repair company and they ran some tests, discovered that the hard disk does not (according to them, he only read this way because the apple store has run the test for a normal hard drive and not an SSD). I'm not super computer savvy, so I took their word for it.

    Now, however, it has been nearly a month and my computer refuses to activate once again. Previously, it has worked well, the fans were running at full blast - what I knew would be a problem (although the repairman told me that they 'fixed' this issue too). So the first time, I downloaded a program called SSD fan control and set the fans to run in silent mode. This second time around, I realized that it was probably a bad idea because it could lead to overheating, so I put manually the fan speed so that we could hear still run, but just not as loud.

    I tried the reset SMC, but no result. Right now, I unplugged everything including disconnect it from the power strip.

    Any other experience of power with a new SSD failure? Is there anything else I could try at home before contacting the computer again repair business? I would not be able to reach at least until tomorrow, and I'm really curious to know how they managed to get my computer back on the first time.

    Also, I've been out of my warranty period for about a year, so that's why I thought that I was not risking too much by exchanging the original for one SSD drive.

    First of all, the original in Middle 2011 iMac hard drive had a temperature sensor integrated in the drive.  More new or replacement of those who do not.

    Other World Computing sells an Apple certified temperature sensor that plugs into the SATA cable.

    https://eShop.MacSales.com/item/OWC/DIDIMACHDD11/

    I just put a 2 GB Western Digital Black in mine, with the sensor.

    I suggest all first, reinstall the OEM disc and see if it boots.

    Put the SSD in an external enclosure and see if it runs...

  • Desktop iMac won't start

    About 2 months ago or not, I've updated my desktop iMac computer 2011 at El Capitan (running 10.11.1).  Everything has been works fine until this afternoon when I sat in for use.  I remember leaving the computer on when I went to work last night and didn't touch when I got home this morning.  When I tried to turn it on, nothing - no fans spinning, no boot screen, nothing.  I unplugged the computer and held the power button for about 20 seconds, but nothing happened.  Does not even plug and unplugginh both ends of the power cord and have switched plugs.  Does anyone know how to fix this?

    If you do not have any audio or video on what means its are not getting any power, check what is obvious, and if not then it is likely a supply failure.

    Hello

    As the error code relates to a short drive Self Test failure - the only real solution to this is to replace the hard drive.

    As your laptop is still under warranty, contact HP to make arrangements for the replaced disk.

    If you live in the United States, contact HP here.

    If you are in another part of the world, begin here.

  • iMac won't turn. Startup disk is full. TDM won't let me edit.

    iMac won't turn. Startup disk is full. TDM won't let me edit.

    My iMac turns off 10 seconds after the start to the top. I tried repair disk running, to no avail. What is happening is because my boot drive is full, off the 500 GB I partitioned in mac, 493,63 GB is taken up. I bought a thunderbolt cable to access the TOC on my mac book, and I have access to my files now. The problem is that I can only copy files. Authorities say I read and write permissions. When I start my host computer, it says "you can still open or copy the files on the disk, but you cannot save changes to the files on the disc. Back up the disk and reformat it as soon as you can. "I'm trying to copy all my files on this computer and remove what I don't want copies, then reinstall OSX on my iMac. The problem is that some files are native to all OSX, so it would prevent me from copying the files. For example, if I want to copy my applications folder, it stops to copy once it reached the app store, because it cannot copy that. It is a problem because when it comes to the library, there are small files in there that I don't know if I can copy, then it stops at the copy and I end up with half of my files and I don't know what I need and what I have.

    Everything you need to copy the disk, then start the iMac in recovery (command-R) mode. Wipe the drive and reinstall OS X from the recovery console.
