Problem 2 solved by starting Windows in safe mode. While in safe mode I tried to change video adapter driver but Windows was having none of it. It didn't just say it couldn't find a better driver, it a couldn't find a driver at all.
So problem 1 still exists. I need a driver for the video card. Going by Palit's current model designations it should be a "Palit 9440" (chip number should read TGUI9440AGi, misspelled in first post)
