The M in your Video card name usually means Mobile/Laptop version.
That's a huge problem, because Google's chrome is not stable with ANY mobile card right now.
*** If all else fails ***
What I would do if I were you is try again with Google chrome BETA release(That's what I'm using) you can find it here: http://www.google.com/landing/chrome/beta/
Its not always as stable as the.. stable release(Mine has never crashed though) and they have more options than the stable version.
