hey there everyone. first off this is for my macbook unibody graph card = 9400m 256 mb-mem. i 've been planning to re-install my 9m series graphics card on my bootcamp side of things. as my gpu's been acting up a bit. so the driver i've got is from the nvidia site. but anyways i was just wondering if i install the one i got from the nvidia site, would that affect my mac side at all. and also does anyone know if i should actually use the driver i got from nvidia's site.? so here are the questions i would like to be answered if possible: 1. will reinstalling the drivers on bootcamp affect my mac side. 2. will it affect the functions to apples extra stuff on boot camp (such as back lighting, backlit keys, the fn keys etc etc. 3. does apple provide a download for their customised updated drivers and most importantly 4. do you recommend me doing this or not. thanks to everyone in advance.
