Early this month I bought a EVGA Nvidia 9500 GT graphics card to upgrade from my old ATI x300 card. Everything works fine except for when I try to play DVD movies. When I try to play and DVD movie my computer crashes to a blue screen with the code nv4_disp.dll I assume that it has something to do with the card so I uninstalled all of the drivers and tried to play a DVD. When I did this, the sound would play but the screen would be blank. I tried to reinstall the drivers and got the BSoD again. I now think it's the DVD codecs, but I don't know how to find new codecs or drivers for the DVD player(Sonic Cineplayer). Please help, thanks. :bang:
