iMac Late 2009 EMC 2374 A1312 - White Screen of Death

Hello Guys,

I have an iMac A1312 with the original hard drive it suddenly stopped working and now it only goes to the WHITE SCREEN after the BOOT.

I tried to REINSTALL the system using the COMMAND + R and then following all the steps to install the system.

After installation it went to the WHITE SCREEN OF DEATH. Is it my HD? a logic board problem? or something else?

Should I buy a new HD and install?

Answered! View the answer I have this problem too

Is this a good question?

Try this easy GPU fix before buying a new graphics card! It fixed the white screen issue on my EMC 2374.

Angelo, you have been watching to many soap operas. What is "WHITE SCREEN OF DEATH", drama?

It's just a failed hard drive. To get you fixed we do need to know your exact machine, there are 11 A1312 machines. Look on the bottom of your stand, get the serial number and input it here, then tell us your machine: http://www.everymac.com/ultimate-mac-loo...

There will be run away fan issues we need to address but know what you need. It's also a good time up upgrade to an SSHD drive. Once we know what you have we can get you to options for drives, remedies for the heat sensor, and the correct guides and what tools you will need to replace it ;-) No biggie! No death, it's just a flat tire, no need to bury it.

I just tried to installing a BRAND NEW SSD right now on the iMac however it boots with a WHITE SCREEN to detect the NEW HD I guess and then it turn off. Am I missing something? I am using an WINDOWS USB keyboard to boot it up using COMMAND (WIN KEY) + R. However it doesnt go to the REINSTALLATION screen, it just turn off.

I do have A1312 it says on the down part. However do I need a pen drive bootable? What do I exactly need to install the SSD clean without any FILE SYSTEM FORMAT. Do I need to format it or put the OS before something? How to do that? Is there a tutorial for it? using iMac and USB Windows Keyboard?

by

mayer,

It is an Apple iMac Late 2009 A1312 (EMC 2374).

With the SSD I can start it up and then it turn off or go into OPTION (alt using PC Keyboard) and see the "Windows" HD icon (This SSD was from another computer). But then I click and it freezes.

What do I need to do to be able to install the OS X inside this old Windows SSD? Any steps? tutorial? Is something else beyond just HARD DRIVE problem?

@angelorecaman - You'll need to find a friend who has a Mac to help you here create a bootable OS installer drive (USB Thumb drive) Follow this guide: How to create a bootable macOS Sierra installer drive Then plug the USB drive into your system and hold the Option key to get to the Startup Manager to select the USB drive and run Disk Utility to prep the drive and then the OS installer.

Hey guys!

I just installed a brand new SSD. Got a USB with the macOS Sierra Installation. Everything looks fine and good to go.

Formatted the SSD Journaled + GUID and then go straight to the installation. After all it keeps booting up and then going to a RESTART your computer... or even WHITE SCREEN OF DEATH again.

What is wrong with it? Should I bake the LOGIC BOARD?

@angelorecaman - I didn't push you to El Capitan nor did the Back Blaze write up I posted needed it. As I stated you would need to go all the way back the Mavericks to get to a version of Disk Utility that would ignore the fact you have a SSD Vs a HD to run the security function. Again, I stated this was not a good idea unless all other methods failed. With a bootable external drive you should be able to run the terminal command to use method outlined in the Back Blaze writeup.

Here's the Deal You'll need to use the tools Kingston offers which sadly requires you run the tool under MS Windows. So you'll need to find a friend (or you own system) which has Windows to run the tool. Then you need a way to connect your SSD to your Windows system. You could take out your SSD and then connect it directly within the systems (desktop) free SATA port. Or, you could do what I recommended which is a lot easier! Put your system into Target Disk Mode and then connect it to the Windows system as if it where an external HD. Now we do have an issue of interface to also solve! This is were you need a special back to back USB cable so you can connect two desktops How to connect two computers with a USB Cable and here is one source for the cable: 6' Hi-Speed USB 2.0 Cable Type A Male to Type A Male

You appear to have a second Mac system here does it have MS Windows running on it? Have you tried connecting your iMac to it in Target Mode and using Disk Utility to reformat the drive? Here we can use a Thunderbolt cable with a Thunderbolt to FireWire adapter which is faster or use the back to back USB cable.

It seems easier to get a friends WINDOWS PC, and then plug my SSD in a SATA PORT and use the tools.

Do you have the exact link of the tool that I need? And what should I do with this tool? If you give me tutorial link on youtube would be a great way to do the exact same thing.

I didn't try any target mode and I dont know how to do it.

However I am not going to buy new cables if i could borrow a simple windows computer and use the Kingston software to do what you are teaching me to do.

Thanks.

Here's the link: Kingston SSD Toolbox

Heres a listing of all of the startup key options: Startup key combinations for Mac As you can see you simply press the T Key when the system startup.

Great!

What should I do after startup with TARGET DISK MODE?

Thanks

* Connect the two systems back to back using the cable.

* Run the the Kingston tools drags from the MS Windows system delete the drive from the MS Windows. Don't format it leave it raw.

* Boot up under your USB OS installer and prep the drive with Disk Utility setting up GUID partition map and a partition then run the OS installer.

But you'll need the back to back cable. I though you were going to take the drive out and plug it into your friends Windows systems SATA port? If you do that you don't need to run your system in Target Disk Mode.

OR, are you trying to connect your MAcBook to your iMac to see if you can fix things that way? You still need a cable to inter-connect the two systems (FireWire with a Thunderbolt adapter)

If you just wanted to see if the system would boot up under Target Disk Mode did it?

@dan

How about if I bring a BRAND NEW HD instead of SSD and all of this complicated process.

Do you think is it going to work?
