Thinking it was a good idea to give my machine a good dig out I was looking through the Add/Remove programs and came across the following. Nvidia display drivers. Nvidia WDM drivers. Winfast PVR. Winfast(R)drivers. Winfast(R)drivers (Note twice) and Winfox setup. My card is a Leadtek winfast FX5600 My VIVO. I have no idea how they all came to be there but should I remove some or leave well alone. Many thanks.
That makes interesting reading and it also shows I am not the only one who has trouble understanding Graphic Drivers. I already have downloaded drivers from that site and will do as suggested. The main problem that I encountered was whether to use drivers from Leadtek site of NVidia. Apparently they do differ slightly.
