It's hard to say what is causing the problem. Lots of apps can take
Explorer down. Or it might actually be an Explorer bug. The problem is
probably not your RAM, though.

Your best bet at a fix is to file the Watson report (that "report this to
Microsoft" thing that should pop up after Explorer restarts).
