To All Who Kindly Replied;
I FIXED IT!!!! It wasn't easy, but I finally got everything worthwhile installed......
First, I had to totally remove the old 275.33 package and stripped my display driver to bare bones - basic VGA only.
Then I opened Device Manager, looked for the display adapter (had a little yellow "!"), clicked on update driver, pointed Windows to C:\NVIDIA\DisplayDriver\yada-yada-yada\Display.Driver and Windows did the rest.
Did a restart, opened the setup.exe in the above mentioned folder and voila! The 296.10 drivers were installed and working fine.
After that, I did a separate install of PhysX & 3DVision (if you try to do a custom install with just those 2, it screws everything up all over again) - and I have everything but the 3DVision Controller Driver and the HD Audio Driver; neither of which I use anyway.
I may have taken a couple of extra steps here and there, but now I know what to do if it ever happens again. I imagine that if I did an express install, I'd have it all in place - but now that I have it working, I'd rather not chance messing it up again!
Once again, many thanks to all of you who had the courtesy to pitch in and offer your help and advice!!!!
