Greeting from Germany. I've the same problem with the notification and no idea to solve it. All I can read here I've done and try. Install and reinstall, formated the harddrive, setup several times a new windows xp. No success. The red button don't disappears.
The next time, I startet the computer, something strange happens: the red button disappears. Then it works for a while.
After a while the red dot is back. I don't no what happened.
I'm desperate and helpless. Somebody has an idea?
