Laptop Model : Asus N46VZ

what i change in BIOS settings are :
  • ■ Launch CSM - Disabled
    ■Fastboot - Disabled
    ■Secure Boot - Disabled

after that, i press F10 to save changes and exit.
laptop will restart, but when restart i got black screen.
Keyboard light, Notification Light all lights up, Fan is running.

what is the possible cause ?
is it VGA ? or something else ?
how to fix this problem ?
