ok i tryed to load an old 3d demo and it caused a blue
screen. i reset my computer to fix it and got a "windows
protection error" so i fixed it by reinstalling my 3d
card. now i get the same thing over and over if i try to
play any games or use the 3d features of my card. how do i
fix this?

ps. ive reinstalled the drives countless times and directx
as well.
