This is the scan I just ran.

In looking at the PDF there were two examples, one with all green lines and the other with the large red lines. Unless I am missing something yellow lines were not described. It would seem logical that could indicate a lessor problem. I am going to run this on the new machine to see what happens.

EDIT: I disabled and reenabled every audio driver in device manager on the old machine without any change. Also the yellow graph looks about the same on the new machine.
Second EDIT: I have run this program a good bit now. It occasionally shows issues. I have in the process recorded some music and watched some video both of which ran without issue. Everything on this old computer is currently running normally.
