Getting three Beeps, Not RAM error

Got this machine in and it beeps three times and three front led flashes when the power button is pressed. RAM error right? Pulled RAM, went with know good RAM. Tried each slot, no change. Pulled HD. Tried to zap PRAM, nada. Reset SMC, nada.

LSI OK. Battery indicator light working.

No history on the machine as it was an eBay buy.

I'm wondering if this is possibly connected to the GPU issues on this program: https://www.apple.com/support/macbookpro...

UPDATE 7/14/17

I see we got another question on this type of error today.

My MacBook don't turn on, only get Beep every 5 sec interval

Since this original machine came in I have the same problem on two more machines:

A: MBP 15" 2012 2.6 GHz running 10.12.5 500 GB SSD & new HD cable

B: MBP 13" 2012 2.9 GHz i7 running 10.9.5

This does not appear to be a RAM error on any of the three machines. On all of the the problem has been intermittent, the machines will run fine for a day or a couple of weeks and then start beeping three times on start up. It does not appear to be heat related nor virus related. I'm at a total loss Apple Support was useless

The screen pictured on this discussion is exactly what I saw on the B machine.

@mayer - I think you have a bad logic board. The error code implies memory or the memory slots are bad Intel-based Mac Power On Self Test RAM error codes.

I don't see how this would be the graphics issue. Besides, this 13" model has an intergraded GPU unlike the other systems which had issues.

Update (03/22/2017)

@mayer - Are the black plastic clips broken at the mid plane? If they are the system was crushed.

Sorry can't offer more here ;-{

Had it as a 13", it's an i7 15". Bad logic board is not what I wanted to hear but suspected.

@mayer will say it is either bad slots or GPU, had a MacBook 15" before doing the same thing with no physical damage. Scrap or resell unfortunately :(
