guys pls help i bought a secodnhand mining card secondhand a few weeks ago, it seemed fine at first, but now i get this on the desktop:

The seller said it was never overclocked, i can still return it for a few more days. How can i prove whether its teh card and not my sysetm? i dont wanna accuse the seller unfairly, sooo i need to be sure its really the card. What tests would hold up as proof? pls help 🙏
