I am in Maine and I thnak you for the help.
Last night before bed I shut down my computer and it said, on the blue screen I see every time I shut down "Updates are being installed (1 of 1) Do not turn off or unplug your computer. it will turn off automatically."
Well that was five hours ago and I still see the same screen.
I felt I was so close to getting my computer back to normal after a weekend of tinkering with it due to a different problem.
Has anyone out there ever seen an update take five hours to install? Is three a safe way to get my computer out of this without holding down the power key?
