Find and install the latest drivers for your hardware.
Click "Application Only" on the www.snappy-driver-installer.org downloads page.
Unzip the installer package and double click the exe that begins with SDIO_x64. On the Welcome screen, select "Download Indexes Only" and wait a few seconds for the program to update.
You do not need to download all of the driver packs (i.e. do not click "Click here to start the download" at the top of the screen). Click "Create a restore point", select any newer/more optimal drivers you want, and then click Install in the red box in the left column.
