XPS 13 2-in-1 Laptop keeps blinking, black screen and blurry fonts

Hi guys,

I got my XPS on last black Friday. But recently it keeps blinking, and has black screen, and sometimes the fonts are getting blurry. I updated each time whenever the system requests. I wonder if there's something to do with the graphics. But i don't know how to do it. It would be great if anybody could help. Thanks.
