I am a little bit cognitively disabled or something and need someone to explain this basic driver thing to me like I'm three years old please

Looking for USB 3.0 motherboard drivers for a Compaq 15-s108na laptop so I can put them in a bootable Windows 7 USB iso and install. Apparently Compaq is a subsidiary of or was acquired by or is just a brand name owned by Hewlett-Packard or something, I don't know, but HP ought to be mentioned. I thought I had the drivers I needed but apparently not really.

The computer looks like this: http://s33.postimg.org/qdao0blxr/2016_06_12_15_37_19.jpg

Which is s little conceing as this website http://support.hp.com/us-en/drivers/selfservice/compaq-15-s100-notebook-pc-series/7234969/model/7485838 doesn't seem to have any USB 3.0 drivers that I can identify up for grabs.

Can feel... my prefrontal cortex... tuing green... help, please?

I tried here https://driverscollection.com/?H=Compaq%20-%2015-s108na&By=HP too but I don't know if this is trustworthy/has what I actually need. There's no mention of mptherboards anywhere.

According to some linux commands I ran with a spare Ubuntu boot disk, my motherboard's "product name" is 2213, the manufacturer is Hewlett-Packard, and the version is 57.46. For all the good that probably does.
