Hi Saurabh,


Your laptop came with Free Dos 2.0 from factory.

Are you currently running Windows 10 64bit? If so,

Your laptop came with Intel® Core™ i5-6200U processor with switchable graphic system --> integrated Intel HD graphics 520 and dedicated 2GB AMD Radeon™ R5 M430 Graphics.

Uninstall all graphics driver listed under Display adapters section in Device Manager. Then,
Try to download, save and install this driver:
