MY TOSHIBA NB205-N313/P (blackscreen)

Hello, I was finding a movie on google and i found what i needed. Nothing illegal than my screen went gray. Just switched it off.
Next day when switching it on I get the black screen with cursor flashing in top left corner. i turn off and turn back on it says under title of the start up screen F2 or F12, but straight after that goes to the black screen. Never to the windows screen. so i click F8 but my safe mode not even coiming up what do i do???
I just CANNOT lose the data on my hard drive.
Is there anything I can do to fix this without losing my info? Idk what to do??

PLEASE HELP!
