Thanks for your help, but I am not pro enough to follow your suggestion. Somewhere, possibly at "Ask Leo," I read that one can minimize memory usage by not placing too many icons on the desktop or taskbar. I removed all icons from the taskbar and minimized icons on the desktop.
Now I found an excellent download to minimize memory usage: StartUpLite by Malwarebytes. I definitely noticed a difference as soon as I ran the program. I highly suggest it and it's freeware.
