Hi:

Your notebook is not supported by HP for W10.

The only suggestion I can offer would be to see if the W8.1 Intel and AMD graphics drivers work.

First, install the Intel graphics driver and restart the PC.

This package provides the driver that enables the IntelHigh-Definition (HD) Graphics in supported notebook models that arerunning a supported operating system. If high-definition multimediainterface (HDMI) video output is supported, this package alsoinstalls the HDMI Audio Driver.

Then install the AMD graphics driver and restart the PC.

This package provides the AMD High-Definition (HD) Graphics Driverand Catalyst Control Center for supported notebook models that are running a supported operating system. For notebooks with switchable graphics modes, this package includes drivers for both graphics processing units (GPUs). Switchable graphics enable users to switchbetween a power-saving graphics mode (normally used under batterypower) and a high-performance graphics mode. If high-definition multimedia interface (HDMI) video output is supported, this packagealso installs the HDMI Audio Driver.
