Issues with my Windows 10

Hello TechRepublic Users!!
I have installed Window 10 in my Laptop two month ago from my friend. Generally I play games like that I download from website. But from last 3 days my laptop on not starting. It is giving the following message on the screen “You PC ran into a problem and need to restart. We are just collecting some error info and then we will restart for you.”

When I restart my Laptop, still it gives the same message. Please give me best way to solve this problem. I do not want to change my window.
