What driver could be used for the nVidia 310M notebook card?

[mehdymehdy]

i have intel hd and nvidia 310m gt218. i wish i can turn off intel hd in mac . because no matter what it's not working. and no one is realy helping out there. the intel hd kexts load but they end up with black screen. anyway i wish i can only turn it off and us the nvidia one. although i know that it wont take over the vga.
