Why do I have to restart my xp 3 times before it works right?

[Billy Nyel]

Every time I turn on my computer, it only displays the desktop background. If I wait long enough I can turn on the task manager with ctrl+alt+delete then I restart my computer form there. After it restarts it shows the desktop, and the icons but not the start bar. If I click on the icons, they don't work or go REALLY slow. I can restart from the task manager but it takes a long time. After it boots up again, everything looks fine but I can't connect to the internet no matter how hard I try. After restarting AGAIN it finally works right. The whole thing usually takes about three hours.
