First, OEM's like HP make modifications to the drivers on a system in order to make the dual graphics cards work well together.
As such you should only use the HP video drivers.
On my Samsung laptop I have broken my video because of this and am unable to fix it without a full reinstall (I can't find the settings that control this).
In my case the AMD driver must be signed by Intel in order to work with the Samsung (and Intel) graphics drivers.
I would first suggest uninstalling all video related stuff, then download and install the drivers/video stuff from the HP website and see if that helps.
If HP doesn't offer Win10 drivers for your system, try installing the Win8/8.1 drivers in compatibility mode.
Also, this can be caused by excessively hot temperatures. Monitor your temps with this free utility: Also, monitor your system's temperatures with this free tool: http://www.cpuid.com/softwares/hwmonitor.html
Blow out the vents/cooler with canned air to make sure that dust isn't causing this problem. DO NOT USE an air compressor or a vacuum as they can damage the hardware.
