If the Crash Reporter is not appearing when the engine closes and there is nothing in the Windows Event Viewer then your CPU is actually not crashing. Are you getting any popups at all when the Editor closes? Is it seemingly frozen and then you CTRL-ALT-DELETE to close the editor?
Can you also take a look again at the Windows Event Viewer, if Windows or any application running experiences any error they will appear in the viewer?

You can eliminate that issue with updating your Intel Graphics Driver via the following link:
