This is kinda weird problem I'm having when I start my computer it loads fine but after logging in to my window xp account it takes about 15 second to load for some reason I can't click start or anything, so I though maybe something wrong with the hard drive after that I download Sea tool and ran it didn't detect any problem with my hard drive next thing I did was do Fresh copy of window xp stalled after that it boot fine no slow on anything so next thing do is window update for couple of times I notice same problem again, Any one know what might be cause of this problem?

Am I understanding correctly that you reinstalled xp? If so, did you install any other programs or did you just start updating windows? What version of XP? What service pack do you start with? What are the specs of the comp?
