I guess I have a similar problem (sure it is not a hardware): every time I restart my computer my standard keyboard shortcuts Ctrl+C, Ctrl+X, Ctrl+V, Ctrl+Z, Ctrl+Y, Ctrl+S, Ctrl+A are changed for something like Ctrl+Insert, Shift+Del, etc. => and I have to again and again re-assign hot keys, customize them manually every time after restarting... Please help figure it out...
thx,
