Matlab hangs frequently while working .

I face the following error, I have no idea how to solve it.

There seems to be a problem with my installation, I tried to fix it by reinstalling MATLAB but it did not help. This similar problem occurs even on MATLAB2015.

Currently using Matlab2016b on Lenevo z50-70 with 8GB RAM, and Nvidia GeForce 850M
