Hi Vincent,
Thank you for your reply.
The issue is consistent when I start the computer cold.
I ran all the diagnostic tests:memory, CPU, display, hard drive quick and extensive, all are negative.
My problems started with Windows Updates around middle of May.
If I do not hear any other suggestions, I intend to reinstall windows.
I subscribe to Windows Secrets and Fred Langa has an article on how to reinstall windows without reformating the hard drive (by selecting upgrade instead of reinstall).
