Cannot access safe mode - computer wont go into safemode only leads to black scr

Hello,
hi

my laptop looks like it has a massive problem.

i have been on various forums for advice but unable to solve - this is the problem -

* it turns on & I CAN get into advanced menus
* it will not repair itself no matter what
* it will not go into any other modes , safe Etc....therefore I cannot restore to factory settings etc....
* ive Tried all tricks such as F8, Alt & F11 etc..... to get into advanced menu settings - all lead to the black screen
* everything i click on\ enter leads to a black screen - only a white curser appears.


its as if there is no way of accessing the computer disc/ hard drive in anyway from boot up. there is clearly a hardware problem but i cannot access anything internal beyond ordinary & advanced menus i just keep being led to the black screen & no activity. the menus work & that is all.

i run Windows 7 on a Dell inspiron 1564


HELP HELP HELP !!!!!!

Many Thanks for reading
