I just upgraded to the new intel coffee lake cpu and 300 series motherboard. I am using my old hard drive and ssd with windows 10. I do not have an optical drive to install the motherboard drivers from the disc and when i turned the pc on, windows 10 already booted. Ive already tried to install drivers via web files i put on an external drive but they dont want to work...is it best i just do a fresh install of windows 10 and wiping my old data and apps? Nothing seems to be working properly because of all the old drivers that are stored in my old drives.
