I am using Windows 7 for my home PC. Upon clicking on my admin profile and typing in my password, the following message appears, "The user profile service service failed the logon." I can only logon to my wife's account (that does not have a password nor admin capabilities). When I try to restart my computer from a previous point in time under system configurations, the folloing message appears, "C windows system32 msconfig.exe" appears. I also have tried restarting my computer in safe mode using F8 during startup but that button does not allow me to enter the advance boot options. What I've discovered is that anyplace that requires the admin password, does not allow entry.
