Some rather basic information please.

I'm retired from a professional life in electronics. My forte was analogue and radio, so although an avid PC user I know very little about them.

I've bought a graphics card as an upgrade. It comes with drivers on a c.d. The accompanying documentation instructs one to first uninstall previous drivers.

What I don't understand is where and/or how in the system does the graphics driver get involved.
It seems clear that if one can still proceed to follow instructions on the screen after removing the original driver but before installing another then the display is not entirely dependant on them.

So where and how does the driver fit in to the scheme of things?

 

Thank you Halo.

You have confirmed what I suspected - that the basic Windows environment has basic drivers.
