I have heard of problems when doing such a project, the same as if you replaced the motherboard from a system without reinstalling the OS. One thing you might think about is booting into safe mode and remove all the system drivers and then let then be detected to make sure that they are using the correct drivers instead of just the wrong driver working some of the time. But in the end you should be okay with what you have done.
