scratched the back of a GPU?

Solution
LOL no it will not hurt your PC. The GPU board has a coating to protect the circuits. Ive slipped and scratched a motherboard with a screwdriver before and it was fine. Your nail is not going to do nothing to it.
Title says GPU, text says cpu, no information as to what type of either you are talking about soooo...putting on my fortune telling hat I would say if it works don't worry about it unless your name is Wolvarine in which case your fingernail could do damage.
