Welcome to the HP Support forum. Thank you for posting !
If you only installed some driver and PC fails to boot now (probably Blue screen errors/BSOD), you can try to use perform System Restore to get back to a state before you installed the driver.
1. Please, shutdown the computer using the power button
2. Power it on.
2.1 As soon as you press the power-on button, immediately start hitting the Esc button (like tap-tap-tap) before any HP or Win logos appear.
This should open a HP Startup Menu which may look similar to this one
3. Choose or press F11 for System Recovery options.
The computer should boot from it's recovery partition to open you various recovery options. Note, that F11 option will only work if the recovery partition is there (not deleted) and intact. From there, you have prenty of options to choose from. Every HP computer comes with recovery partition present to assist in tough moments.
Please, perform "System Restore" first in an attempt to fix the issue. Please, restore back to previous days (restore point) where the issue was not present. Here is more info:
