Hello everyone. I had quite the same problem. Bottom ram did not work. I did try to place plastic strips on the bottom and the edges and worked just for one day (?). Next day it did not work again. I did try to unscrew a quarter of the ram brackets but that solution didnt work. So when i connect the computer power while i press the on/off button, it turns on, but the loading bar doesnt complete and the system reboots itself. I run a macbook pro 17 inches i7 with 2x8gb ram. any ideas?
