Hi, I have a laptop that has just started this problem. When I start it I have to press ctr -alt-delete to log on. If I am in the office I usually log onto the domain, when out of the office I log onto the 'computer'. I have a username setup and of course I can also log on to the computer as Administrator. It doesn't matter how I log on, using username or admin, to the domain or to Computer, I type the username and password in and then the computer starts to load personal settings but actually never gets any further. I am able to login in safe mode onto the computer (not the domain). I have run Malwarebytes and it did find 4 items but it is clear now. The computer had AVG installed but I have uninstalled it to see if that was the problem. I have also done a system restore from safe mode but this made no difference. All the log files show no indication of what might be causing the hanging. CHKDSK found nothing. Any help with this would be appreciated. I am hoping that I don't have to reinstall XP.
