FWIW - I know that there's a more recent version of the RTL8187 driver available from the Realtek website, and that there's a more recent version of the SFEP driver from the Sony website.

Please visit the web site of the manufacturer of the Device (Not SONY except for the SFEP.sys driver)
If the manufacturer doesn't have drivers, then search Google for the exact model number and see what's available at the other major manufacturer's websites (you'll have to do this for the Alps touchpad)

If this doesn't work, then wipe the hard drive clean with DBAN or KillDisk and then install Win7 clean
