I just finished my first computer build and my cpu seems to have arrived damaged. When the replacement one (intel core i7 4790, same as the original) gets here, will I need to reinstall anything? I understand that most if not all of the drivers are stored on the mobo side.
If you are replacing your cpu with the same cpu and you already have all your chipset and motherboard drivers installed then no it should be as simple
as just changing over CPU's and you will be good to go
