OK - Here is how I solved my problem. Hope others can use it.
My computer had a PCI-E slot available.
I bought a PCI-E(xpress) video graphics card. In my case it was a EVGA GF 8400GS PCIE card. It was on sale at microcenter for 30.00 after rebate.
What threw me off was that the card had a vga and dvi-d connector. I wanted VGA/VGA.
A dvi-d to vga converter was in the box - so that solved my problem.
I installed it on a Vista machine. I did NOT have to disable the onlboard graphics card. I did install the NVIDIA support that came on a CD with the Card. I suggest you then immediately go to their website and get then newest version. It has a nice interface that
allows you to pick the primary and secondary.
Pretty simple - mad at my self for waiting this long to fo this. I works great.
