HI@TonyTone44, Welcome to the HP Support Community!

Don't worry I'll try to help you out.
 
Did you make any hardware or software changes on your PC?

Are you able to boot into BIOS?

As you mentioned when you power on your PC you are getting a black screen with the error HP PC HARDWARE DIAGNOSTICS UEFI. 
 

If you are able to boot into BIOS try restoring the BIOS to default and check if it helps.

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.

Try the steps recommended below.
 
Press CTRL + Alt + Del on the blank screen.
Click on Task Manager
Click "File" - "Run a new task" If there is no "file" option, please click on the task manager under the "details"
In the pop-up window, enter "msconfig" click "OK"
In the system configuration window that appears, click "Service" and uncheck "App Readiness".
Click "Apply" --- "OK"
In the following window appears to click on the "restart"

Also, try the steps recommended below.

If you have previously disabled App Readiness
Boot the PC
Click Start and type Services
Open desktop app Services and find App Readiness
Open the service and set Startup type to Manual
Click Apply and close the window
Download and install HP Image Enhancement for System Login using this link.
Reboot PC

If you have not disabled App Readiness
Boot the PC
Wait 15-20 minutes for the boot process to complete and desktop to load
Once on desktop, Download and install HP Image Enhancement for System Login.
Reboot your computer and let me know if this helps you fix the issue.

Also, try updating the BIOS and other drivers on your PC using HP support assistant.

Refer this article to know more information about using HP support assistant.

If the issue still persists try running a system diagnostics test on your PC and check if the hardware components on your PC are functioning correctly.
