my mobo is asus p8h61mlx. i set up a user password at BIOS and i didn't do anything with the administrator password.
i can access the system using my user password but i can't access BIOS anymore.

after hitting delete to enter setup, i am prompted with login password. i tried typing nothing and hitting the enter button, considering that i didn't set up admin password at all, but to no avail.

i don't want to open my pc and reset the CMOS rtc ram to clear the BIOS password because my pc is still under warranty and opening it would make it void.

please help guys.

thanks.
