You may not believe this, but... the only people who have access to the "error codes" are the Apple in house engineers. In all the years I have been fixing Mac's I have never needed to traced an Error Code. Even when you know what it means, it won't help.
The best action with a computer fault is to determine whether it's a hardware or software at fault.
The way to do that on a Mac is to start by booting up the computer from another clean MacOSX.
There is a very simple spare system loaded on your Mac already.
So... try that first.
Reboot your Mac. As soon as you hear the startup chimes, hold the option key down until you see some icons.
Choose the "Recovery" icon to boot from.
This will startup the machine with only a basic OS X.
Now... does you problem still exist?
If it's OK then the problem is probably a damaged OS X software.
You can also try and Re Boot while holding the "Shift" key down. This will disable many extensions and may fix some issues, but it really slows the machine down while in that mode.
Then try re Booting as Normal and check for the problem.
If you find that your OS X is wounded then I would suggest that you get a free (trial) copy of CCC http://bombich.com/download
and Get yourself an external hard drive NewerTech 1 0TB Hard Drive Voyager in stock at OWC
(1TB partitioned into 2)
I use the dock & drive above because it is so versatile for a technician as you can plug in the drive of your choice. Eg 1 for movies, 1 for Backups etc. I also prefer 3.5" drives as they are faster and more reliable than the 2.5 inch drives.
The choice of supplier & size is totally yours ....... I don't get any kickbacks from any suppliers. (I'm Down Under in Oz)
Download from Apple the Yosemite OSX10.10.3
Apple Mac OS Mavericks
and copy this to one of the empty partitions. You could use a 32GB memory stick formatted for Mac (Disk Utility) and practice installing the new OSX on to it, to get the feel as to how it installs.
Use CCC to make a clone to one partition on your external hard drive. When completed, you should boot from this clone to prove that you have an exact bootable copy of your faulty drive.
Once this is done you are free to use "Disk Utility" to erase your internal Hard Drive & Install the new (Clean) OS X10.10.x onto the drive. When completed it will ask you if you want to "Migrate" your old files & settings back to your newly installed OSX (Yosemite)
Then you Mac should be as new again.
Or you can just use the new OSX10 as is but you will have to type all your details back in and set up your network etc.
Hope this Helps
If it does... Please Give me a Tick of Approval for all my typing!
It's often the only thanks we get...
