Welcome to Arch. We need more information. What have you tried? Have you read the nvidia and nouveau topics in the wiki? How did you install Arch?

https://wiki.archlinux.org/index.php/NVIDIA
https://wiki.archlinux.org/index.php/Nouveau

Please edit your title and the content of your post to make the title more descriptive and remove the useless "Help!!" and exclamation points.
