When I'm working on another window, it will kick me back to the home screen

when I'm working on another window, it will kick me back to the home screen every 15 seconds or so. It's like when it check email or something, it goes to the home screen.

This problem is often caused by "Google Drive." If it's installed, I suggest you remove it according to the developer'sinstructions. You may need to boot in safe mode to do so. Back up all data before making any changes.
If you use Google Drive and don't want to remove it, then try deselecting the option in its preferences to show a status icon. According to reports, that may be enough to stop the Finder from crashing.
