missing folders?

[rescue-svc]

Using XP Home and just encountered a few problems! System Tools shows only Security Center when clicked. All other folders like Restore, defragment, & etc are not showing. On the control panel clicking on user accounts does nothing at all. Clicking Administration presents an empty folder. Help!!
