Hi,

Try the following.

Download the Intel HD Grphics installer on the link below and save it to your Downloads folder.

http://ftp.hp.com/pub/softpaq/sp74501-75000/sp74713.exe

When done, download and reinstall the Chipset driver on the following link.

http://ftp.hp.com/pub/softpaq/sp72001-72500/sp72068.exe

When the Chipset reinstallation has completed, do not restart the notebook as prompted, instead, open your Downloads folder, right click on the Intel Graphics installer and select 'Run as Administrator' to start the installation.  

When this has completed, shutdown the notebook.

Unplug the AC Adapter and then remove the battery.  Hold down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.

Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.

Let windows fully load for a few minutes before checking.
