How to Improve Base Score on Windows 7 x64

hi

i have an "acer aspire 4741 notebook" operating on Windows 7 x64 Home Premium. i'm a bit worried about my "base score" and would like to improve it.

i've been on the acer 4741 download page and have updated a couple of my drivers that were available there:

1) Chipset > 9.11.1025

2) Intel(R) 5 Series 4 Port SATA AHCI Controller > 9.5.6.1001

3) Intel(R) HD Graphics (VGA) > 8.15.10.2189

these were the main ones i updated plus a couple others. i can provide a complete list of the drivers i've updated from there. fact is my notebook is just about a year and a half old and have been taking very good care of it. so i'm a bit baffled as to why my base scre should be reading so low.

base score > 4.0

-----------------------

1) Processor - Calculations per second > 6.4

2) Memory(Ram) - Memory operations per second > 5.5

3) Graphics-Desktop - Performance for Windows Aero > 4.0

4) Gaming Graphics - 3D Business and gaming graphics performance > 5.1

5) Primary Hard Disk - Data transfer rate > 5.7

i'm sure most of the drivers on the page are not the latest drivers available but that's what they are offering on the page. i'm now wondering what drivers i need to update to improve the score and if i can download the drivers directly from here.

any advice will be much appreciated.
