If you are having any problems installing or after installing these new drivers.....completely uninstall "Gaming Evolved"/'raptr' before trying to install the new drivers.
Removing this is not a easy thing. First go to control panel>remove a program> and uninstall Gaming Evolved. Next, use regedit and 'search for all instances of raptr''...there will be several. Delete them all. Now when you use "Custom Install" for the new drivers you will see Gaming Evolved listed....uncheck it if you do not want raptr installed....leave it checked if you do want it installed. If you can't 'uncheck' it..and it says it's "already installed and up to date" then you didn't uninstall it correctly/completely. Go back to regedit and search for ' raptor' again.
EDIT: sigh...No, this does not make your drivers work. You have to first remove raptr...THEN REINSTALL THE DRIVERS AGAIN FOLLOWING THE SAME UNINSTALL/INSTALL METHOD.
