Acquired this computer from a friend about a month ago. Custom built, but has a few parts that are a few years old, not a big deal. When I received it, I added 1 more gig of ram, a TV tuner card, and tried to install an additional video card to no avail. Moving on, after all was installed, all was great.A few days later, when I did the usual reboot before I retired for the night, and when Windows booted up, I could not log on to either Admin enabled account. The guest account was / is enabled and is the only way to log on to Windows. I have read several forums, and so far none of the remedies and suggestions seem to work. I'm pretty good, knowledgeable wise, but I'm no engineer. Please, if someone out there can give me a hand in "laymans's" terms, I'm willing to figure this out too. Thanks... Tom

Hi, Could you please clarify the exact error message? Is it called Temporary profiles? If so, a temporary profile is issued each time that an error condition prevents the user's profile from loading. Temporary profiles are deleted at the end of each session, and changes made by the user to desktop settings and files are lost when the user logs off. A user profile consists of the following elements: 1.A registry hive. The registry hive is the file NTuser.dat. The hive is loaded by the system at user logon, and it is mapped to the HKEY_CURRENT_USER registry key. The user's registry hive maintains the user's registry-based preferences and configuration. 2.A set of profile folders stored in the file system. User-profile files are stored in the Profiles directory, on a folder per-user basis. The user-profile folder is a container for applications and other system components to populate with sub-folders, and per-user data such as documents and configuration files. Windows Explorer uses the user-profile folders extensively for such items as the user's Desktop, Start Menu and My Documents folder. We can perform the following method to resolve such issue: 1. Restart your PC to release the locks on your profile. 2. Log on with another administrative account 3. Delete C:\Users\%username% 4. Delete C:\Users\TEMP 5. Delete the registry key matching your SID from "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList". Check the value "ProfileImagePath" to make sure you pick your own profile. 6. Restart once again.
