Hi everyone. I just bought a new computer with Windows8. I'm used to XP so this is very new to me, although I think I'm getting the hang of it. Anyway, all of the sudden yesterday the lock screen keeps coming on every few seconds and makes me put in the password to get back to what I was doing. It didn't do this until yesterday, for the previous 5 days since we bought it, everything was fine and I never saw this screen except when I first turned it on. Please help me figure out how to make it stop? It's driving me crazy. I think it started after a windows update but I'm not 100% positive. I know I didn't change a setting, I don't know how to do that yet. Thanks so much.
