My laptop isn't turning on and my Novo button menu turns off

As you could see from the title my Lenovo ideapad 330 isnt turning on no matter how long I hold down the power button and when I tried the Novo button menu to turn on my computer it's there for a few seconds and then my screen goes back to being black. It's weird because a day before this problem happened my computer was working perfectly. Any ideas, tips or methods to fix this????
