Problem: Desktop is blank, only wallpaper is displayed, icons and taskbar diappeared. Rightclick doesnt work. explorer.exe not working. Can't use kelly's tweaks as they don't start (I believe due to explorer.exe not working). Tried to activate it by running it at task manager, not having any of it. Adaware couldn't find any virus or worm, etc. It feels like a program is blocking explorer.exe from running as it tries and the taskbar appears for half a second but then vanishes again. Tried creating new user, the same problem. Tried launching system restore it doesn't let me go to a previous date as no other date is bold. Finally I am thinking of xp repair install.

Any suggestions from anybody?
