Creating Unique Buttons for Specific Product

Hello, I need help creating a set of unique buttons for some of my products. I am trying to make a streamlined process for customers to choose parts for a PC. For example, I have them first go to a processor collection. After adding the one they want to the cart from a specific product page, I want navigation buttons at the top that take them to my graphics collection. The button that I added works perfectly but when it comes to the graphics product page, the same button appears and sends me back straight to the graphics collection. Please help! if you don’t understand I can explain in more detail.
