the rest of the accounts on my computer work fine, but mine, witch is a standard account, won't let me log in. I've tried system restore back as far as it would go, witch was about 1 1/2 weeks ago. and it still didn't let me logon. along with my account not working, it says the same thing for new accounts, I even tried to make a new admin. account but it didn't work. I've run avast home antivirus, Spybot, Windows defender, all system tests, and nothing.
I asked this same question on Microsoft Tech net forums, two replies but neither one worked. it won't let me use the guest account either. I'm usually pretty good when it comes to computers. My comp. is about a year old and it has worked fine aside from crashing every once in a while. I keep my computer pretty tight as far as firewalls, antivirus, etc. I can't see why it won't create a new profile.
