If you go into device manager, you should have a list of hardware installed on your machine. Some of them might have an exclamation or question mark, choose from those, right click on them and click on update driver.
Thne point the wizard to wherever you extracted the drivers to.
Alternatively some drivers run an executable that will ask you to re-start your machine, upon restarting the device should be picked up, and installed correctly.

Ignorance is not necessarily Bliss, case in point:
Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.
