I recently upgraded my system by installing a new motherboard, MSI Z87 Gaming, my old mobo was a MSI K9A2GM-FIH; a new CPU, Intel Core i5-4590, LGA1150, the old one was an AMD 64 Dual core. Also, installed compatible RAM. Everything is working fine, but I'm not sure I'm using the Intel Chipset. When I run diagnostic programs, it's still showing my system as being AMD64 build. I'm not sure what I have missed, but I need to know how to change my system to recognize my new chipset.
