My laptop will not boot up at all.

Hi,
I recently tried to turn my laptop on and it will not boot at all. When I turn it on, the HP Invent screen pops up, and then after that the screen goes blank. If I try pressing ctrl alt delete or f8 to start in safe mode, it just goes to a black screen then restarts itself and does the same thing over. Any idea at all what I can do or what might be going on? Any help would me really appreciated!
