Just installed the newest XP update and WE HAVE PROBLEMS... help!

[Jurollo]

I just restarted my computer after the newest XP update and now when it tries to load windows it gets to the logo then a quick blue screen with nothing on it and it reboots immediately and does the same thing. I tried booting it from a Windows XP disk but it gets to the Windows Setup screen and eventually restarts after loading all the devices.
