Problem Solved!
After I installed the new VIA Motherboard drivers, I got the open gl module to work in SANDRA once again.
It told me that my open gl wasn't "hardware accellerated and that I should check for new drivers.
So I did.
I dl'ed new NVIDIA drivers from Microsoft and it worked.
This time.
Graphics are quite impressive now and very smooth.
I love that "My Drivers" program!

Thanks everyone!
What a valuble resource this place is!!
