Cannot Get Service Pack 2 or Automatic Updates

I recently put a new motherboard in my old case and reinstalled my original
XP Home Edition. In the past, I've been able to get my automatic updates and
service pack 2. This time however, there were no extensive updates to
install and the 10 or so files that are recommended do not install when I
request the update.

I'm stuck because the drivers I need to install for the new motherboard
indicate I need at least service pack 1.

I need some help if anyone knows what's going on.
