Sigh. I installed a 128GB SSD drive into my Mini (along with the original base 500GB), and i've had a few instances of the computer just choking. I have the activity monitor open and have plenty of ram available (16GB installed). Is it possible something went wrong during the install of the SSD? I can't understand why a 2012 Mini would freeze up after 5 minutes of playing Bejeweled 3 (from steam) on the middle setting. I installed iStats menu and all 4 CPUs are to the max.
