MBP 15" black startup screen with sound?

[ember92stepz]

Hi all, i just got a new macbook pro 15" and has been using it for a few days. I usually let it sleep between uses during the day and shut it down at night. Then a problem started occurring yesterday, when I turned on the power in the morning, I could hear the startup sound but the screen is black instead of the white background with the apple icon on it. And it was only when i touch the trackpad that my desktop appear..
Any suggestion on what might have caused this?

if it's new i would bring it back to apple and have them replace it with a new one. this machine may be problems in the future.
