Replying to Computer help.please!

alright, if i try to log onto my user name on the windows xp main page thing, it gives me this error and it says "windows can not load you personal profile becasue of a corrupt file" or something like that. so it takes me to a "tempoary user" and it doesnt have like any of my things on my desktop,i have to re install shit. all my files are still on the computer i just need to find them casue im not on my user name on a temp on. so if anyone know how to fix this that would be awsome,becasue if i log off or restart on this temp user name thing, it does not save anything i did, so when i log back on i have to re do everything and its so god damn annyoing. so any help would be great. thanks guys
