Hello I was playing with my windows xp services a few weeks ago and my computer started fast and worked fine. Now all of a sudden it still boots quick (just half a turn when booting) but when i get to the login screen it stalles there for about 40 seconds doing nothing and then shows me my desktop? How can I fix this? Before I had this problem, I would see the login screen for a few seconds and then see my desktop. Please Help.
