Blue Screen of Death for nvidia 7800 Go drivers

I am using Vista Beta 2 Ultimate and the nvidia 7800 Go drivers and I keep
getting blue screen of death errors when I try to use anything 3D; like
screen savers, Windows Media Player or anything that touches the direct3d
system. It got so bad blue screening that I had to put XP bake on my Dell
9400 laptop. disappointing. Will there be drivers that will allow better 3D
for the Go 7800 before the next Beta or Release Candidate or could someone
pressure NVidia to get there act together?? Please. :-)
