So I have chosen to upgrade my computer. I am going to switch cases and change out my motherboard and cpu from a Asus m5a78l-m plus/usb3 and a AMD fx 6300, to a MSI B450 Tomahawk Max and a Ryzen 5 3600. I understand how to build it but not sure what to do afterwards like with drivers n'stuff. Would I have to go in and manually delete my old drivers or what would I have to do?
I'm also really confused on what to do with the whole Windows 10 thing, I have watched youtube videos on it but I am still confused. I'm using my same 1tb hdd (also adding another 4tb hdd and a 1tb m.2 ssd) from before which has Windows 10 already installed. So with that same hdd will windows 10 still work or will I have to do this activation code thingy.
