Unable to load image nvlddmkm.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for nvlddmkm.sys

Probably caused by : nvlddmkm.sys ( nvlddmkm+ee940 )

The problem is caused by your graphics driver. Run Display Driver Uninstaller(DDU)
Make sure you tick the Uninstall C:/AMD and C:/NIVIDA folders while you are in DDU when you are done running DDU install your graphics driver again and you should be good to go! This is the guide for DDU: Drivers - Clean Left over Files after Uninstalling
