If it's just the USB 2.0 ports that don't work, and you don't even get a "bing bong" and the device appearing in device manager, then it could be a hardware problem.

Updating the graphics card driver will make no difference to the USB 2.0 problems. There is a later Intel USB 3.0 host controller driver which might help:
