Needing help to update my graphics driver

Hi,

I'm trying to update my graphics driver but the update utility don't work. I use Firefox 27 and the latest version of Java is installed.

I also tried to update it manually but I can't figure out from wich generation is my graphics adapter.

The following is all the info about my desktop's system I can provide:

SYSTEM

Processor : Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz (4 CPUs)

Memory : 1910 MB

System Type : Windows XP Professional 2002 version Service Pack 3

DISPLAY

Name : Intel(R) HD Graphics

Manufacturer : Intel Corperation

Chip Type : Intel(R) HD Graphics (Core i5)

DAC Type : Internal

Approx. Total Memory : 1024.0 MB

Version : 6.14.0010.5237

Also, I fear for incompatibility or any other issues. This my first time updating drivers.

Thanks!
