It looks like your device was not designed to work on windows 10, that said, you may want to return to windows 7 to resolve this issue, as it was shipped with the same as per the product specifications page, if you wish to revert to the OEM (windows 7) you may want to make use of the HP recovery media: click here for details on how to get one.
That said, if you wish to keep windows 10, you may at your own discretion but HP does not support it for this device as it wasn't shipped along,
And I personally suggest you to make use of 3rd party websites such as: driverscape.com (as it contains most of the drivers for your device, once you select HP in it).
I hope that answers your query,
