OK, this is NOT necessarily a simple problem.
Windows will NOT install drivers if it can't identify the hardware correctly; more common that you might think.
First, try Windows Update, you might be lucky. But NOT if the "manufacturer" hasn't supplied them to Microsoft and they've passed testing.
After that you're pretty much on your own, and just looking at data inside Windows won't tell you much.
You will need to identify by any means possible (e.g. labels/markings on the hardware and googling/searching) EXACTLY what it is.
Then go to the manufacturers web site and find the drivers, download and install them.
Often this is confused by generic/OEM hardware where the original designer MAY have drivers but more likely someone further down the chain (e.g. computer "maker") produces modified drivers.
