He everyone I was replacing out a video card in my sig rig as the card was defective when I was doing so I noticed some marks on motherboard they are white in appearance and I'm not sure what they are I have attached pictures.
I tried to clean it with some isoprop and a q tip with no success so im not sure if its a scratch in the pcb or if its just a cosmetic issue.
