Constant crashes in editor

The thing is that i use Unreal Engine and then suddlenly, it crashes. I don’t know why this is happening, and it’s anoying. I’ve tried other versions, from the 4.9 to the latest, and it gets me the same problem (not for 4.11, but it does not work properly because i have win10 and it’s really anoying to get the “not showing drop menus” bug). What can I do?

What I’ve done so far:

  • Uninstall and make a clean instalation of the editor
  • Uninstall and make a clean instalation of the graphic card drivers
  • Try different projects: as far as i know, all the new projects i’ve made, eventualy crashes. This doesn’t happen with the Content Examples project and other projects on the market.

There’s a solution for this problem?
