Would you explain how you restore default BIOS. ? because I'm struggling with the same issue !!!
Hi..
Did you already find the solution of this problem?
Because I'm currently facing same problem like you did. I already reinstall the Nvidia drivers but my laptop cannot detect the Nvidia hardware. I also have tried many kind of method that I found but still didn't work :( Its been a year since this problem happening. Please tell me if you already know the solution.
I'm using ASUS K55V, windows 10, Nvidia GeForce 610m
