WTF???

My explorer.exe has gone insane. First off it's no longer automatic. So I start off with no taskbar or start menu. When I make it run the only thing that comes up is my documents. My icons are all still there and besides the missing taskbar and start menu everything seems to be fine. I've tried running spybot and ccleaner. I've also tried SFC /scannow. Nothing seems to be getting my comp back to normal. Help me please.

That's only going to be as a last resort. I have too much good stuff on this computer to lose.
