I just got windows 7 64-bit ultimate edition for my laptop, and I notice that it does not read my graphics card. The graphics card I have is the nvidia 8800 gts for my sony vaio laptop (model vgn-fz283bn). My computer was working correctly with it when I had windows vista business 32- bit, but for some reason it is not showing on windows 7 64 bit version. When I look at the graphics card I have (in the hardware tab) it said I had the standard vga adapter, when I actually have the nvidia. Please help me with this issue so I can get my nvidia operating with the computer.
