Why are there lines on my screen?

I just started my kotor play through on pc and when Im'm playing on dantooine or under ground tarris I have mods installed but I don't think thats whats causing them. Also I'm playing off of a disk if that means anything. Info n what causes this or a fix would be appreciated.
