Computer Help!

GOOOOOGA

Rookie
For all you computer whizzes out there... or anyone who knows how to fix my problem.

After logging onto Windows, all I see is my desktop, I don't have any icons or even a start menu. My cousin suggested that I go into Task Manager and do an "End Process" to explorer.exe and then run the New Task of explorer.exe. This got the start menu and everything back in tact. But I don't want to have to do this every time I want to use my computer. Is there any way I can fix my no-start-menu problem? Thanks.
