You mention Mobile and 4 Series, from which I will presume you are talking about a (very old) laptop. For laptop devices, it is recommended that you use the graphics driver that is provided by your laptop manufacturer. Using the generic graphics driver from Intel is not always going to be supported by a laptop (so many have a hybrid solution with non-Intel graphics solution included).
When you say "VGA Standard", what do you mean? Are you saying that it is using the Standard VGA Driver? This is likely an indication that you indeed do have a non-Intel graphics solution included and thus need a driver other than Intel's. Again, consult the manufacturer's drivers page for your laptop.
Hope this helps,
