Video jerky. Video freezes while audio continues. Scrolling in browser video jerky.

I've run every diagnostics this computer offers, both from the HP Support Assistant to the UEFI reboot diagnostics.  The diagnostics all say it's fine.  I've made sure all the updates have been installed and are current.  The issue is the video is jerky.  Sometimes the video freezes but the audio continues, then the video starts again in sync with the audio.  Scrolling in my browser is also jerky sometimes, like it lags the mouse wheel.  Sometimes when I move the mouse arrow it freezes temporarily.  Sometimes I'll start to type and it takes a second or two for the letters to start appearing.  Keyboard and mouse have new batteries.

I understand that you are getting video freezing issue on the notebook, I am glad to assist you.

Also, ensure Windows is up to date.
