Hi, once you do have the correct download and then burned it to disk or flash drive, the install shouldn't be too difficult if you follow the instructions on that link, however once installed you will need all the drivers as being a fresh install they will have to be put back.
You can download the drivers you will need from here :-

Chipset drivers should always be installed first, then after that, Windows may fill some of the gaps with its own generic drivers, the others can then be chosen from that link.
