So, I ended up replacing my old 17" Macbook Pro with a 15" MacBook Pro (the one with 4GB of memory and the 512MB video card). So, I went ahead and installed Window XP 32 bit without thinking about it more. After spending a little time with XP, I decided I really wanted to install Vista 64 bit. Unfortunately, after installing the Boot Camp drivers, I've been getting the BSOD randomly, usually within a few minutes of loggin in. The only thing I could catch from the blue screen was that there was some sort of error with the file nvlddmkm.sys, which appears to be an nVidia file. I was wondering if anyone has any idea how to solve this?
