Yesterday I received windows-updates on my computer, as usual the second Tuesday of every month. During installation of these updates, everything stopped. My computer freezed, I had to turn it off and on. But since then I have not been able to use my adm.account. When I log in, it freeze, and I can not do anything. The first couple of times I logged in, the program-ikons were there, but now all I get is a blue screen, and I have to turn off my pc. I have another account, and it seems to work. When I try to use Xpress recovery F9 at startup, I get this message: Hd does not support HPA. I notised that my anti-virus Norman updated itself yesterday, about the same time I received windows updates. Anybody know what to do? One year old pc with XP serv.pack 2 Edit: Problem solved. It seemed to be related to the latest windows-update:"Windows Genuine Advantage Notification (KB 905474)". For some reason I can not install this update. I would, of course, like to know why. Can anyone help me?
