If the Mobo is identical to the old one you probably won't need to do anything. If it differs then you can usually get away with a Repair Install.
Personally, I prefer to save any data I want off the Hdd onto a flash drive or CD then Zero the drive and do a fresh install.
You will need some thermal paste and that can be obtained at any PC shop.
