Hi! Thanks! I’ve tried sudo pacman -S nvidia-dkms but ends on “Error! Installation aborted”
As for or over “pacseek nvidia-dkms search” I don’t know how to do it.
As for updating bios I prefer not too. My Garuda was working around 2 weeks PERFECT! My games were also perfect, everything was perfect until today. Whit my actual “old” bios. I prefer not put my hands inside there 
since I’m a such a IT absolute ignorant
