SilentStorm16 :
what i did was just uninstall all the old drivers and install the new ones but it seems way slower than its suppose to be. there is also a Activate windows Text at the bottom of my screen and i cant get it off.
you will most likely have to buy a new os if you didnt buy the OS before a retail copy not a oem if you upgraded from a existing copy on a machine you bought then your pretty much need to buy a ( RETAIL) not oem copy of windows 10 so you dont get butt hurt ever however say for example that you did buy say 8.1 retail you could have used that
you cant simply rip out hardware and put new hardware in doesnt work that way its looking for more then windows drivers the os looks for bios drivers that dont exist
what is your motherboard anyway that had the i3
that and youd need ddr4 ram as well etc as ddr3 doesnt work with skylake
