When do I uninstall my old video cards' driver, before or after installing the new card?

I am going from a ATI card to a nVidia card, but it should be the same process.

delete your old one first, then install new one
Reply:The easiest and most reliable way to uninstall display drivers is with the "Add/Remove Programs" window. This should always be the first method you try. All but the most ancient drivers from NVIDIA and ATI can be removed this way. Most other recent display drivers can also be uninstalled in "Add/Remove Programs".





To use the add/remove approach, open the "Control Panel" and then double-click "Add/Remove Programs". In Windows 95, 98, and ME, select the "Install/Uninstall" tab. Then for all versions of Windows, find the entry for your display drivers and click it. The entry is usually the name of the manufacturer of the GPU on your display adapter followed by "graphics driver" or "display driver". Then just follow the prompts and remove the driver. You will then be asked to restart Windows.





If your display driver doesn't support "Add/Remove Programs" then you have to use one of the other approaches: if you're running Windows 95, 98, or ME, then you install the standard driver; or if you're running Windows 2000, or Windows XP, you uninstall the driver in the "Device Manager".
Reply:Uninstall the old drivers before you turn your machine off to install the new card.
Reply:It should before installing the new card definitely otherwise you will create a conflict.
