I had problems with all versions of the nVidia IDE drivers with my 8RDA+. I simply ran the Microsoft driver. However, I haven't tried the latest nVidia IDE driver on the 8RDA+, which works fine with my NF7-S. The NF7-S had problems with previous nVidia IDE drivers just like the 8RDA+. So maybe try the latest; they come separately, or at least did at first.
