Recently upgraded my wife's Dell Inspiron 1525 laptop from Windows 7 to Windows 10. Her computer began shutting down (turning completely off) at random times. Tracked it down to NIS. Uninstalled NIS and shut down problem went away. Used Norton Removal Tool to verify uninstall complete. Tried to reinstal NIS and it gets almost through installing and computer crashes and shuts off. Have used NRT 3 times and same thing happens. Why won't NIS install correctly?
Thanks for any help,
Jim T
