QGIS installation has stopped running when startup?

My laptop is Windows 10 and I have installed QGIS 2.14 64bit twice; because due to some problems I uninstalled the software and reinstalled it. Now: "qgis has stopped running when startup"

I have searched for solutions on GIS SE and here is what I have done:

1. I delete the .qgis2 but it fails;


2. I tried to run qgis-ltr-bin.bat as "gis.stackexchange.com" guides but it fails;


3. I tried to uninstall and delete everything about QGIS in C: drive as "gis.stackexchange.com" guides but it fails;


4. I tried to install other software like 2.18 64bit but it also fails.
