Hello bren_n2391,
Thank you for that information. I just checked on the HP website and it is showing that HP has not yet provided Windows 8.1 drivers for your HP ENVY 14-2054se Beats Edition Notebook PC.

What if I don't see my operating system from HP's software page?
If the operating system you are looking for is not listed on the software download site, HP does not have software or driver downloads available for your computer and operating system. HP provides software and driver updates for the operating system that originally came with your computer as it was designed and tested for the operating system purchased with the PC. Changing the operating system on your computer (upgrading or downgrading), puts the system into a configuration that might not work with the hardware design. If you you must change the operating system, get drivers from the manufacturer of the component you need. For example, if a computer has NVIDIA video hardware and was upgraded to a newer version of Windows, someone would go to NVIDIA's web site to download and install an updated driver.

You could try to perform all HP updates through HP Support Assistant. If you don't see HP Support Assistant installed on your computer, download it from here.
Once HP Support Assistant is installed, click here for assistance with how to use the program.

Let me know if this works!
