Invisible polyline

Hi I can’t seem to get a visible polyline/curve. I’ve tried troubleshooting in display but thinking it may be a graphics card issue? It was working fine until I installed some other large programs (creative cloud) now Rhino is showing some glitches. Any help be great

Run systeminfo in the command line and paste the result here.

i read of such troubles. one solution which was frequently given is to update your graphics drivers.
