If it were me, I'd restore from my full system backup. If for some reason you don't have one, I'd back up any data I didn't want to lose, then restore to factory settings. After that you'll need to reinstall any software that didn't come with the computer.
had a power bump, after that and some daggone MS update, the kitchen comp. lost the "favorites" folder. tried sys restore, when i did the comp lost it's network location, went from the home group to an unavailable network, so, now for some reason i can't get it back to the home network. i'm to dumb to get this where it needs to go, please help.
