Acer aspire 7520 after bios update computer is not...

Question

First off i have to say this is my third post becuase in the other ones people just post a solution and they never talk back again, i cant even tell them what happened after i did what they said.

Ok so i posted a thread asking where i can find the drivers for my laptop.

someone told me the site URL and i was very happy cuz now i can update all my drivers.

So the first thing i did was i download the new Update for my laptop from the acer site and i unzipped and click on flash.exe something like that

It flashed the New bios to my laptop and then it asked me to shutdown my laptop and turn it back on.

I did so

and when i turned my laptop on everything seemed like it was going fine all the loading lights were working and i cud hear all the fans and hardrive but i noticed that my screen hasnt turned on.
So then i shutdown the laptop and tried again and everything was fine again and my screen was turning on.

I know that everything works cuz when i put a cd in it reads with but i dont know how to acces the cd or the bios cuz i cant see the screen,

So how do i fix this without having to send it to Acer
