More aboutwin7 drivers
Windows 7 should either contain the drivers for your mobo or if you have the PC connected to the internet when you install it should go online and automatically download and install the proper drivers.
Motherboard specific drivers are on your mobo cd and newer ones will be found at the manufacturers website under support for your model of board. Win 7 doesn't really update anything on your mobo other then loading generic drivers.
