Sunni - If you have the onboard NVidia video, then you will really have a hard time. I tried for three weeks trying all the rpms, tar balls and older nivdia drivers, doing mix and matches. Also tried the different Redhat Linux kernels. I installed Redhat 7.3 around 15-20 times.
Even nvidia wouldn't answer my emails when I told them I had the onboard video. I ended up using an older ATX PCI video card which worked just fine.
If you also have the onboard NIC and audio, the NVidia tar balls work just fine.
Best of Luck,
