Hi Guys
So my M/B is faulty and i need to replace it, if i swap it for a new one, and plug everything back as it was before, will i need to reinstall the OS or will it just boot up like before?
Secondly, if i were to upgrade the motherboard, would i be able to do the same thing and avoid reinstalling the OS?
Thanks
