Yes, I tried all that. More add'l info: I got my Dell PC with 16 MB Nvidia GeForce, took it out, and installed 32 MB Nvidia GeForce. WinXP didn't let me run the driver CD that came with the my videocard. I got a worning suggesting that I don't change drive setting; and if I do, the card would not function properly. I used the card on my old PC. It worked fine. After I installed it on the new Dell PC, I lost control over it (tools, monitor controls, etc.) Any suggestions?
