Hey Im new to this site and new to upgrading pc's. Ive done a lot of research on it and know a little bit now. I have a Dell Dimension 3000 Desktop P4 3.0GHZ 1GB Ram and just upgrade my video card to a 3DFuzion ge 6200 PCI 128MB. I am running it on Windows Vista Home Basic which I upgraded to a few weeks ago from windows XP. Someone at Nvidia told me this would be the perfect card for this system so I purchased it. The card installed fine, updated the drivers and everything, but ran into a problem when I went to play a game. I wanted to test the card out so I downloaded a demo of a game online. It installed fine, but then when I went to play it, the screen froze and the imfamous blue screen came up telling me the driver had to quit and the system had become unstable. The computer then restarted. I tried again and it had done the same thing. I am lost on this because I did everything I was supposed to with the installation. Anyone got any ideas what could cause this problem. Im hoping its nothing serious.
