NB: You will also need to install the drivers for the MB, there are no Windows 10 drivers for the MB and the latest chipset drivers available are for Windows Vista, this for info only atm and please do not install any drivers for now.
Have you previously had Windows 10 Pro 64-bit running without issue on this computer.
As previously mentioned there are no specific HP drivers for Windows 10 but there may be compatible drivers available from Microsoft via an update, get Windows fully up to date then run Speccy again and post the updated url for us.
