page fault in module shell32.dll

After surfing the net I found that I couldn’t open the control panel or even search for a “file or Folder”. I rebooted the PC and started getting the message “explorer has caused an invalid page fault in module shell32.dll” When you close the pop up error message the pc hangs, and you can go no futher. If I reboot I immediately receive the same message. I can howver start the pc in Safe mode. (: (if it can start in safe why not make it start in the live mode, i love that concept) Any ideas? I think it’s in the registry somehwere.
