It seems something in the operating system is remapping Alt-x to
<help-echo>, and it repeats it several times.  Did you install some
program recently?  are you using autohotkey or similar to remap keys
in windows? changed the language/keyboard settings for windows?

You can still get the Alt-x behavior (Meta-x in emacspeak) by pressing
ESC (release key) x

A kludge that might work is inserting this in .emacs

(global-set-key (read-kbd-macro "<help-echo>") 'execute-extended-comment)

or this, since it appears repeated 5 times for each Alt-x press: 

(global-set-key (read-kbd-macro
    "<help-echo> <help-echo> <help-echo> <help-echo> <help-echo>")
    'execute-extended-comment)
