G635LX-XS97 cant detect internal display and cant access bios

2025 strix scar 16 purchased a week ago. Was running ok if a bit buggy, I thought I just needed to learn the nuances and continue updating things. Would frequently utilize far more CPU than GPU when playing games like forza and destiny, and would struggle. I changed the power setting to the highest one that requires reboot (full GPU use). Now the internal display stopped working. So windows and myasus could not detect the internal display, only my external monitor. However on bootup the rog logo shows on the internal display and the camera still works with Windows hello ... Seems like the display works but maybe software issues? Also tried changing settings in armoury crate but the system wont allow me to change the power mode saying its handled by a setting in nvidia, Nvidia control panel does not have said setting, windows does not have said setting. Tried to change this in bios, this worked 1 time allowing me to switch back to the balanced/windows controlled setting. But it fixed nothing.

Now I cant access the bios. I have removed the SSD and that didn't work either. 

Tried all the key combos like Ctrl win shift B 

Reset windows (kept files) - not fixed

Reinstalled bios - not fixed 

Installed older bios - not fixed

Can anyone help? For 2 days I've been watching videos and reading forums. Will contact Asus after this full Windows install (no files kept) is complete.

Update... Clean Windows install did not help. I then updated the bios with the exe from Asus website. After rebooting from update, now internal AND external monitors not working. Still no bios access and still get the rog logo on internal display, nothing else.
