What does this mean for my computer?

(I asked a question about this earlier but I can’t find it….) My desk top has been glitchy for a few days. I deleted cookies and caches and history and unknown programs, ran scans and restarted. It would help for a an hour or so, then get glitchy again. So I decided to restore it to an earlier time.
Well, it was taking forever and ever. For two hours it said, it was “restoring registry.” Then we left the house for several hours. When I got back it was still doing that….so I cold cocked it. Which is bad but I did it anyway.
It came back up OK, with notification that the restore had not happened, but what is going on with that? Any ideas?
