I have a Dell Dimension 9150 witn OEM Windows XP Pro SP2. Just made a reinstall of Win XP and quick formated the disks in the process, and after launching XP first I had a lot of difficulties with missing drivers, but I think I have managed to download an install them all. My main issue is that Windows update don´t work... I click windows update from the start menu, and then after a few seconds after looking quite normal, it goes into some wierd 404 page and gives me a loong error code on the left side of the window. Please anyone, do you have some advice?
