Asus A53SC (or K53SC) bios problem

[usblaidas]

Hello, dear friends. Today I messed up my notebook's BIOS. It has NVIDIA Optimus technology, and though AMI bios tool I set Primary display to PEG (so i thought it might use GeForce instead of Intel HD). The thing is, geforce is connected to intel hd and then intel hd i connected to monitors and ports... And the result is I can't get any video output!!! Can anyone help me please? I have to repair it this week, or my father will kill me... Any help is apreciated Thank you. Thank you, guys
