I have tried a number of riva tnt2 cards on my computer, Aopen 3d navigator, 3dblaster tnt2 ultra, pixelview tnt2, and i have the same problem with them all. All direct3d games freezes after a few seconds. What could cause this? I use win98 and directx6.1 swedish edition. I have tried numerous drivers from Creative ,Aopen and Nvidia. My hardware configuration is pII 266, soundblaster awe64 value, internal us robotics fax modem, 96 meg RAM, fireball HD 7.6 gb, Atapi cd rom 36x.
