Ok guys so I just would just like to know if it is possible on windows 10 to do a complete motherboard, ram, and cpu swap without reformatting my hard drive. I currently have a very old asus p6t deluxe v2 with a intel i7 920 that i would like to upgraded to a asus H170 pro gaming motherboard with a intel i7 6700K with DDR4 ram and a new graphics card(gtx 1080. I'm currently using a 1 terabyte harddrive for windows 10 and also my current OS was upgraded from windos 7 to 10 using the free upgraded, I keep seen online that it is possible to do but i would like to get some more input on this, thank you.
