Looks like a video issue ... has this game ever worked properly on this machine? Or it has always been like this?
DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

You jumped the gun on hitting Save All Info in dxdiag: as you can see in that file, half of it is missing. Please try it again, but WAIT until the green progress bar is complete first.
