You will WANT to re-install Windows. Yes it is possible, but it will cause furstration more than anything. I would recommend doing a clean install. Not only are you switching motherboards, but you are going from Intel to AMD, so that will be even MORE drivers to worry about.
Again, you can just go without the re-install, but it will have so many errors, you would have wish you done it int he first place. Plus, you have to think about how you are going to activate Windows now since you are doing a hardware crash.
