My year old MacBook Pro has started restarting randomly
My computer has started restarting randomly while I am using it. No pattern. My husbands MacBook did this a couple years ago and a friend overseas fixed it but I have no idea what to do now. Any ideas?
MacBook Pro (Retina, 13-inch, Mid 2014), OS X El Capitan (10.11.3), OS X Yosemite 10.10.5
