Razer Blade stealth

I’ve had the computer for like 9 months. It’s worked fine doing what I need it to do. It worked fine a week ago. Went on a little vacation. Turned it on and dead pixels started showing. Every time I tried to open anything it would take a few moments to load and show a black screen. Often would stay on the black screen unless I tried to press a few buttons then it would close the app immediately. I can’t open anything hardly.
