new vga driver and color problems

I have just upgraded my video driver for my Gforce 7800 GTX card from 77.77 to 163.71. Although I am not having any real problems with how my pc is working, my color settings are all messed up. I have been trying to re-set them like they were before but I just can't. The desktop settings are ok more or less, where I am having problems is the video settings for my films and games. Everything seems too bright, the white is too flashy, too strong. If I lower the contrast it becomes too dark. Also before my PC only had nview from nvidia to correct color settings, but now there's also nvidia control panel. The problem is that they work independently from one another. It's already 5 days that I am at this and I am losing my patience. Nothing looks good anymore, games are too bright or too dark, when i fix them then the videos are too bright or too dark, especially that white color which is burnout. Does anyone have any idea on why after changing driver i have these problems?
