Inserting a larger ram into my laptop causes windows to BSOD frequently, and going back to the old ram does not fix the issue once it is triggered. The only solution is a clean install of windows with the other ram (I have spent tens of hours on this situation) I know that both rams are working.
I have a new driver that gives me reason to believe that the larger ram might work now. I want to try it, but I don't have to end up having to reinstall windows.
What would be the most robust way to backup my entire C: and restore it if a problem occurs?
