I was installing a game that was taking a while so i went to the store real quick and had about half my battery left, i got home and my screens black and i don't remember what it was saying but it just kept repeating the same thing that covered the whole screen. so i shut it off, and now it wont come on. it was working fine 30 minutes ago, and i know my power supplies good. every time i hit the power button the green power light lights up once then quits and nothing happens. tried removing battery then doing it but i have no idea.
