Thanks for the feedback.
I believe that the GPU problem is now solved.
Upon receiving my GPU from Amazon I shot over to the ASUS site and downloaded the Driver.
It turned out that the ASUS driver was not the latest from AMD for this card.
The ASUS driver was two behind the current one.
As you advise, I will open a separate post for my other issues, which seem to be lessening, but have not yet gone.
Thanks again !
