I recently upgraded an older computer [Dell Dimension 4550] to Windows 7 and found I needed a graphics card that supports DirectX 10. After I installed it & turned the computer on, a standard VGA graphics adapter was automatically added with no option to cancel. The instructions for new driver requires the removal of old driver before proceeding. I went to Device Manager and uninstalled the standard VGA driver but of course, to complete the uninstall, I must reboot my computer. This automatically reinstalls the standard VGA again . Please help me out of this endless loop. There must be some simple way to stop this madness! :- )Thanks.
