I recently upgraded my system from WIN98 to XP. The upgrade went smoothly and everything seemed to work perfectly for a while. However, after a few weeks, the OS loading times suddenly increased, to the point that at the moment it takes 4 to 5 minutes for the computer to do a full boot up, with most of the time spent at the "Welcome" screen. The problem was sudden, not gradual, and I have checked the system for viruses and it turns out to be clean. There have been no hardware changes either ...
I don't know if anyone out there has any explanation for this, but I am rather concerned!!

I am also having this same problem. It seems the only way for me to pass the welcome screen is to press alt ctrl delete.
