OK here’s my 2 cents…read a bunch of these comments, finally decided to just replace the RAM, took out 4 GB, replaced with 8GB. Installed RAM………bummer, same problem: loss of cursor control, 3 beeps, repeat, weird lines on display, auto shut down. Tried holding top RAM down gently while operating, no go. Finally, just removed the bottom RAM, left top in , good to go so far.
 
One very strange clue was that if I moved the MBP at all, it was instant loss of everything, so I knew it was mechanical. In one iteration, the moment I used the left click, it failed instantly. Apparently, replacing the bottom RAM slot is out of the question, but how to make it stay in contact is essential to the issue. The loosening of RAM mount screws is something to look at. I also think that holding the bottom RAM at the right angle may be an option as a work-around. That may be achieved by using a piece of dense foam above it or under it to alter the angle of insertion, I’m trying that next.
