notebook problem

[2weak]

i wanted to start my notebook in the safe mode [is it called like this?] but i didnt remember the exact button i had to press so i just randomly pressed every f button.

suddenly theres written searching and then ;deleting; or something similiar without that the program asked for a permission.

there was no way to cancel this so i shut down the laptop.

when im starting the laptop now the tft remains black :-(

i have an asus a6t notebook.
please help me!
