I just picked up a 2013 Mac Pro that needed some work. I was able to get it running, but GPU A and the 2 left side memory slots do not detect memory (memory beep errors). I checked and my Pram battery is still sending out correct voltage and I reset the SMC just to be sure. It was shipped to me, so I'm not sure if it maybe took a hit along the way (maybe a reseat of the cable connectors?)

Do this mean that the main logic board & GPU A are failing?
