Did you run windows update ?

Almost all Dell drivers have to be installed manually, here they are.

Everything under "other devices" looks like it needs a driver.

Use this page.

Just do them all, except the bios and your audio is already done. As you install them you will see the devices in device manager loose the yellow mark.
