Your forum icon is about how I feel right now. :) Also, thank you for moving my thread to the appropriate forum. I was in a rush to get a solution and didn't really scour the topics like I should have.

I have downloaded the file you linked and I have the same problem. I completely understand you asking me to download again. I did so and I tried installing it, but I get the same message.

I have also downloaded another driver. Instead of entering my model (Dimension 4550) into the driver search thing in the dell site, I entered my service tag number. This time I got a list of only two drivers, which I am now about to install.

Also, just because it didn't occur to me before, it's possible the "PCI Input Device" is my graphics card that I also haven't installed yet.

I will post an update after I burn these new drivers to CD and then transfer them to my other computer.

--Also I have installed the Chipset as you asked.
