Check Device Manager to see if there are any Yellow "!" "?" under Sound, video and Game Controllers.
If not, right click on each listed device and click properties, select remove. Do this till all entries are gone then shutdown and re start your Computer. windows will redetect devices and install Drivers.
Would be a good idea to have your Toshiba Driver/Configuration disk handy.
