Try to restart in safe mode. Press and hold the power button on the front of your computer, then press the button again to turn it on. Quickly hold down F8, and when the boot menu shows, select Safe Mode. Login, and then if your icons still don't show up, try to reinstall windows.

in task manager go:

file%26gt; (new task) run.. and type ''explorer.exe'' simply your explorer is not responding on boot up, you have disabled this from starting on start up.. good luck
