In order to properly diagnose if this is related to the initially posted problem, we need to know more about the circumstances around when the freeze occurs. (ie. What type of project your in, are you using custom assets, etc.) Also, does your whole system freeze, or just EU4?
Additionally, please post your dxdiag: (Windows Start Button>(search “dxdiag”)>Launch dxdiag>select “Save all information”>attach text file to your post.)
Thanks.
