I am not tech literate so I was confused about the Troubleshooting Guide...

I could be wrong since I'm not familiar with these, but I don't really think that this "Mobile Intel 4 Series Express Chipset Family" is really a graphics card.
...as the name says: "chipset", not "graphics card".

Also for the second question, I don't think it's possible to get external graphics card for laptops.

At this point, all I can suggest is that you go here and download the latest drivers for your chipset and hope it works.
