Start Menu Gone

I no longer have my start menu or any icons on my desktop. I tried running spybot search and destroy and ad-aware, but they didn't do anything. When i go to my processes through task manager explorer.exe is not there. I try to load it, by going to new task, it was there for a little while then it disappeared again.
