XP User Account Problem

[JPA9]

On my Windows XP, I have three user accounts...my own, an account for somebody else, and a guest account. I signed onto my own account and tryed to double click the internet, but nothing came up.
I tried double clicking my documents...nothing came up.
It seems that I cannot access anything on my account except Task Manager. I've checked the other two accounts and they're both working fine, hence the reason I am online now. It's just my account.

Does anybody have any idea what the problem could be, and if so, how can you solve it?

try changing your a/c to an administrator a/c.
go to control panel--user accounts--click on your a/c--then change my a/c. now tick the comp administrator box and save. that should solve the problem.
