As for the shaders, that's weird... I am playing on the defaults (ENB) and it works just fine and that's on my laptop believe it or not with Nvidia GT635M.
What I've also found throughout the years when dealing with 'reinstall and install' is that... if you remove something already it leaves a trace in the registry that could corrupt your next installment. There's a great software for dealing with this called "Revo Uninstaller" that makes sure it removes every trace from the registry and throughout the drive, even if you are not sure that it removed everything... you can also do it afterwards manually. Also prior to that, make sure you have also removed the directory in "My Documents" but if you have saves there, be sure to back them up first though.
Other than that, I don't see anything wrong with your setup... it must be a corrupted installation and in order to fix that -> Revo Uninstaller always worked perfectly with me because it removes the already leftovers that could corrupt the next installment (also manually removing the directory in My Documents).
