Thanks Trouble, I'm in business now. I installed a chunk of those drivers from the website that you recommended. After I installed those Dell drivers, I again attempted to load an NVIDIA driver (that didn't help me on three other attempts!) and after my system rebooted, I was in business.
This is my first post. I 'liked' your post. Is there any other thing in this forum that is customary to click on to show appreciation to someone who answers one's question/post?
Thanks for your time.
