windows xp start up problem

[oppajer]

hi guys, well while i was tinkering with the lil computer, i kinda made a boo boo.... the problem is that after it posts and boots up to the section where it says "windows xp professional" and has the little bar on the bottom loading. after that the blue "welcome" screen is suppose to show up, but it never does....i reset the cmos and set everything as default and still no luck. any ideas?
