are you loading the nouveau module early via mkinitcpio.conf modules
array? if not, i'd do that first. i don't know what you've read so far
but i'd start with the arch wiki on nouveau then go to the nouveau wiki.
yours is the nv110 family.
nouveau feature matrix:
early support for maxwell and glamor last summer:
you could also just install the binary blob from nvidia and see if that
fixes the issues as another has suggested, though that would be a *last*
resort for me, assuming i owned any nvidia chippery, that is.
