Windows 10: Can someone tell me what’s wrong with my laptop?

As of yesterday my computer screen has been flickering and blinking and freezing after I turn it on and use it for a little while. At first I thought it was just one of the apps I opened, so I restarted and the same issue appeared again. I tried looking online for solutions but I couldn’t test any of them without my screen freezing and flickering. I decided to leave it be over night and not touch it until right now. Now, my laptop won’t even turn on and the light underneath the keyboard keeps turning on and off. The laptop I have is a Lenovo Yoga 920. I haven’t touched this laptop in a little
