Question Alienware m17x r3 bricked bios

[Verocity_]

My bios is A12 unlocked
120hz 3D monitor
Recently upgraded from a GTX 580m to a GTX 880m
Windows 10
I enabled internal graphics device and switched primary display to SG and when I rebooted, the laptop just wouldn't show bios nor boot to windows...
I'm at my wits end please help me

Omg I dont know how I fixed it but its running now and I could get to bios. i think its because I did CMOS reset.
