does anybody have a dead i7? would be interesting to sand the pcb down layer by layer and see how the pads are meshed together...
that might reveal something to explain why it always happens at the same spots...

or, like i said previously, if you look at the socket and the lever and the way the socket moves and closes, it seems the pressure isnt distributed evenly among all pins... the top of the socket seems to get more pressure than the rest, and vcc is only on the left side...
