Dell does not support Windows 8.1 on this system - you may be able to find drivers from Intel (Chipset and integrated video) and AMD (hybrid video) but Dell will not have drivers for you.

You can try this it works often. Highlight and copy the 2nd line in the group of 4 then paste it into your prefferred serch engine. It should take you at least to a page that will supply info on where to get the driver.

I believe it works better with some hardware and not so with others. I myself have been seaechimh for 2 weeks for the ethernet controller driver and no luck. I called support and I think8// I would have better luck calling the whit house and asking to speak to the president.
