Entire Screen "Pulsates" every 12 seconds. Chime sounds just before each time.

[AnthonyDS]

My entire screen "pulsates" about every 12 seconds.  By pulsate I mean it shrinks slightly, almost like the screen is breathing.  This does not simply happen in an open window, but is actually the entire screen, including the Desktop itself.  The pulsating is preceded every time by a two-tone chime. Since this is so hard to describe I am up including a dropbox link to a video of the problem below.   When the pulse happens, all operations are momentarily stopped and sometimes the cursor shifts positions.  Certain windows may also close during the pulse, though these tend to me pop-up type windows- program windows do not seem to be affected. This is a Pavilion  27 all-in-one running an AMD processor and Widows 11 Home.  It's a fairly new unit, having been purchased January of 2022.  So far I have run the on board diagnostics which have all passed, with the exception of the video test, which cancels out each time.  It does not render a "fail" but the pulse causes the test to cancel each time.  Any help would be appreciated.
