MacBook Pro 15 Pre-Retina 2012 randomly shuts down and powering issues

My MacBook Pro works completely fine aside from these issues. A few times, the laptop has just randomly shut down out of nowhere and on two occasions I have not been able to turn it on without plugging in the charger. As soon as I plug in the charger and turn it on, I can unplug the charger and the laptop will work fine off the battery. Doing an Apple Hardware test, it will not past the Memory Test. It just freezes. I have brand new ram, a brand new hard drive, and a brand new battery installed in the machine. Is it possibly logic board related?

Your machine uses :

  • RAM Type: PC3-12800 DDR3L Min. RAM Speed:1600 MHz
  • Details: Supports 1600 MHz PC3-12800 DDR3L SDRAM SO-DIMMs (204-pin).

Also see: How do you upgrade the RAM in the "Mid-2012" 13-Inch and 15-Inch MacBook Pro models? How much RAM of what type do they support?

  • Standard RAM: 4 GB Maximum RAM:16 GB *
  • Details: 4 GB of RAM is installed as two 2 GB modules, no slots free.

*Apple officially supports a maximum of 8 GB of RAM, but third-parties have determined that this model actually is capable of using up to 16 GB of RAM with two 8 GB memory modules.

What did you install into it?

I use Atomic to test RAM: Micromat - ATOMIC

UPDATE

Could be a RAM or a RAM slot issue. I would first take it back to the original RAM configuration and see if the problem persists, or if in testing you still get the error.

The ram I have was ram that I purchased off of a manufacturer on amazon which stated that this ram was specifically for this model. When I still had the original Apple ram in the laptop, I was still experiencing the Apple hardware test freezing, but I had the laptop with the original ram inside for a very short period of time, so there would be no way of knowing if the random shut downs were occurring then as well. I have 10GB in the computer right now (8GB + 2GB ram sticks)

Hey! So I just test the ram with the software you mentioned and it came back successful. Despite this, could there still be possible issues with the RAM or RAM slot or is it likely related to something else? Thanks in advance!

Does it pass the Apple memory test now?

Unfortunately it is still freezing.
