You may need to go into the bios, and change your compatibility mode from UEFI to UEFI + Legacy
Also for good measure.. You should try and update the display driver for your card.. To do so, go here http://www.geforce.com/drivers
Click download in the automatic driver updates section. And download and run the driver detection utility. If it finds any suitable drivers allow it to install them.
And for good measure, go to the hp website for your specific computer model. And check and see if the have a BIOS update you can download from t he driver section for your version of windows..
If they do, only download and install the newest bios version..
If you encounter any problems or run into further issues, let me know.
