Flashing question mark folder, HDD okay. Bad logic board?

Texto:

MacBook Pro 13.3" - Late 2011 (Macbook Pro 8,1)

* 2.8GHz Core i7 (2640M)
* 4 MB PC3-10600 SODIMM
* Model #: A1278 Sales number: MD314LL/A
* OSX Lion 10.7

So, over a year ago my computer froze up while I was using it a few times over several days, every time I had to do a hard reset.

The last time it happened, it never started up again. I only get the flashing question mark folder.

My research made me think I needed a new hard drive. I brought the computer to a "professional" repair shop in my neighborhood and paid for a diagnosis and to test my hard drive just in case I wasn't correct.

Next day he says I need a new hard drive and everything on my old drive is unsalvageable. So I purchase a new 1TB SSHD from him and install it myself. I still get the flashing question mark folder. I go back to the "professional" and after some unpleasant interrogation he admits he didn't actually test anything, but just assumed I needed a hard drive because of my symptoms.

He offers to test my old hard drive for free (free? I actually paid for it the first time!) and he now says he was mistaken, my old drive is just fine, and I need a new logic board. Of course, at this point I don't trust him, so my question is...

How can I determine whether or not I need a new logic board?

I have reset NVRAM and tried internet recovery. I am able to open Disk Utility, and my hard drive is not listed in the left hand column. Same results with the old drive or the new drive. I basically cannot get the computer to recognize any internal hard drive I install. If I plug in a thumb drive or a flash card they are recognized and I can format and partition them without issue.

=== Update (12/02/2016) ===

Oh, I bought a case and the wire for my old hard drive so I could use it as an external drive. It worked just fine on my other computer and I was able to copy all of my data onto my other computer. So I know for sure the old hard drive works just fine. I gave the new drive to my son, and he uses it as an external drive for his computer, so I know there was nothing wrong with that drive either.
