I have a Dell D830 laptop running windows XP SP3. When I logon, the start button/task bar/system tray show for a couple seconds, then goes black for about 1-2 minutes then the task bar/start button/system tray re-appear and the laptop runs just fine.
The taskbar will reappear and remains the normal blue color.
I have deleted and recreated the profile and the problem still persists.
The core issue is slow startup and the taskbar going temporarily black
