You didn't need to post a copy of the dxdiag.exe display, simply list your System Model and BIOS.
So you have a GL502VS (7th Gen Intel Core) or GL502VSK, not a GL502VS. Please label further correspondence as GL502VSK.
First, you should update your BIOS to 308.
Have you reinstalled Windows?
Did you retain a copy of your eSupport Folder and run the ASUS Installation Wizard within that folder?
Have you updated any drivers or software from the ASUS Download Center for the GL502VS instead of the GL502VSK?
