problem with installing cuda GPU Driver

Hey, I’ve bought an acer 5742g notebook yesterday, it’s got a nvidia geforce GT 540M cuda and It’s got 1Gb of dedicated video memory, as you may know this model of acer got another vga on it’s cpu, Intel HD Video processor.
when I’m about installing the geforce driver i get this message that you should install the intel graphics driver first. after doing that I could install the geforce, but here’s the problem when i go to the display setting i can’t find the geforce graphic but the intel, and the video memory is just of the intel not the geforce. it’s just when i have full access to the nvidia control panel from the windows control panel… if there’s anyone who could help me!?
