Install Windows 10 Creators Update
For Windows 10, download and use hijackthis, it is from the spybot people and is a basic task manager with some extra features, but it can shut down processes that Windows won't do. Once you have gotten the rest smoothed out, then use that software to trim back the running processes and ease up on the system.
I install update and work for me, I get 31 Mh/s from 2-3 Mh/s.
