You need these drivers for:




Base system device:


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, unzip and run the setup application.


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