Hi:

 

You need these drivers for:

 

ACPI\HPQ0004

 

ftp://ftp.hp.com/pub/softpaq/sp64001-64500/sp64144.exe

 

Base system device:

 

https://ftp.hp.com/pub/softpaq/sp46501-47000/sp46999.exe

 

For the other issues, I would see if updating the chipset driver to the latest version on the Intel site and restarting the PC, resolves the problem.  The driver will work on W10...download, unzip and run the setup application.

 

https://downloadcenter.intel.com/download/20018/INF-Update-Utility-Primarily-for-Intel-6-5-4-3-900-S...

 

If that doesn't work I suggest you start a new post, because there are no W10 drivers for those devices.
