Can not recognize GPU or onboard camera

Hi I have a Sagar Np9150 laptop that i recently installed Win 8 on. The only issues i have with it is that it doesn't recognize my GPU and my camera. I tried downloading drivers for the video card (HD Radeon 7970m) and camera (Bisoncam) but i haven't had any success. I'm trying to play Guild Wars 2 and it looks like its running on my base intel graphics. Can anyone point me in the right direction on how to resolve this issue. Whether it be to download a different set of drivers or if the issue is somewhere else, i can't figure it out. Also, my backlit keyboard that i was able to change the colors on when i had windows 7 can no longer change, it's just the color blue or it's turned off. The command to access the software that enables me to change the colors no longer seems to be recognized because nothing happens when i hit it.

Thanks for your assistance.

If that laptop has dual graphics you'll likely have to get the driver from the manufacturer, Sagar. That HD Radeon 7970m likely has a custom ID that the normal Nvidia driver can't ID. If you can nail down the model of Bisoncam camera you have you may be able to get a driver from Bisoncam. There is probably a utility you need to install to cycle the keyboard backlight. I'd look at the Sagar site for that.
