Screen flashes black every now and then???

Hello guys, I'm needing to know how to fix my brand new laptop screen, every now and then it will flash black. I don't know why it's been doing this bc it's brand new, taking care of, never been dropped and banged. Is this normal for Dells windows 8.1? Here's my CPU-Z Validator 4.0 if you need it, I don't know any other way to present my specs.
