Dead Laptop

Hello there, i have laptop hp pavilion dv6 3125sc. I flashed the bios and the screen got blank. When i turn on the computer the fan is running and HDD too, but the screen remains blank. I searched for the solution on google and i found that i have to put the bios on USB stick. The bios is on HP page, but there is no such a file that i have tu use and rename.
Sorry for my english if there are any mistakes.
I appreciate any help.
