Hi,
did you try by updating the driver through Windows Update??
run it and check the .optional drivers.. it should give you at least the basic driver to make it work..
since you said you downloaded the driver (from Dell I assume).. then double click the yellow exclamation icon and update the driver by browsing the folder where the driver got uncompressed..
good luck,
