Chipset Driver Conundrum!!!

Hello Fellow techies - I have been tasked with re-building a daycare computer  that does nothing but stream live video feeds from the various daycare rooms. The hard drive on the old compter kicked the bucket and then come to find out, the specs on the old computer that died did not meet the specs of the new Protech DVR software. So I ended up upgrading to a slightly newer Dell (from a GX260 to a Dimension 3000), made sure all the specs were there, but there is one last thing that needs to be done... updating the chipset with the latest driver and I keep getting the run around and errors at every turn!!!

I first did a general system utilties scan which said I had an i865p/g/pe/i848p chipset. But when I searched for this model on the Intel website nothing could be found! Then  I did an Intel system utilities scan and it said I need the most updated driver for 865G - so I tried installing that driver and it told me that:

So then I come here to Dell and try to download the chipset driver for my computer tag and guess what - I get this error from the dell website:
