chipset driver update

i need to try and update the chipset in my hp desktop but not sure what to download. Ive been having issues with a logitech media keyboard were the number 5 on the key pad stops working. Ive installed the latest drivers and Logitech have asked for the chipset drivers to be next.
can anyone tell me what i need from the folowing screenshot?

Which hp pc is it?
Looks like the intel 865 chipset but not totally sure.

thi is what i found but whne i run the Intel chip set finder it says 865 as well
The link says its 848!?:confused:

848 and 865 are essentially the same chipset - 848 is single channel memory and 865 dual channel.

You want the inf update utility from here.
