My graphics card didn't install properly

Hello,

I Currently have a windows 7 64Bit-Service pack 1
4 GB RAM and 286GB ddr
The Processor: Pentium(R) Dual-Core CPU T4300 @ 2.10GHz (2 CPUs), ~2.1GHz
The system manufacturer is Packard Bell. The model is a "EasyNote TJ65".
My Graphics Card manufacturer is Intel. I Went to there site but everything i download i get an error saying it can't be installed or something. I Went to Packard Bells Site, search my exact OS. I Downloaded and successfully installed a drive which i think is a graphics card, but when i restarted my system to check if anything changed, nothing did. I Still have version "8.15.10.1892" Date is "02/09/2009". These are the details that were given for the Product i installed:

Product: Intel(R) Chipset Device Software
* Release: Production Version
* Version: 9.1.1.1020
* Target Chipset#: Intel(R) 5 Series/3400 Series Chipset
* Date: August 26 2009

How and where do i find the proper graphics card for my system? Thank u
