My Minecraft keeps crashing so I want to wipe all of the data from my Minecraft so that I can reinstall it and it would be fixed, but when I reinstall Minecraft, all the folders and the crashing didn't change. I've gone to lots of websites and they all say to uninstall then reinstall but it never works. Can you tell me how to wipe ALL data from Minecraft?

Edit: I have moved the .minecraft folder into the bin but when I reinstalled it, it still crashes. Any other suggestions?
