Hey there! @Rose001, Thanks for stopping by 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 or F2 page from the PC?

Have you tried checking with an external monitor? Does the issue persist?

Were there any recent windows update on the PC?

Excellent description and a great diagnosis done. It is greatly appreciated.

Completely resetting the computer can resolve many issues that cause a blank screen. Follow these steps to perform a hard reset:

1. Turn off the computer.

2. Disconnect all peripheral devices and remove all USB devices and media cards.

3. Disconnect the AC power adapter.

4. Press and hold the power button for at least 15 seconds.

5. Reconnect the AC power adapter.

6. Turn on the computer.

If you are able to boot into BIOS try the steps recommended below to restore BIOS to default.

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.

Also, I would suggest you enable Fast Start-Up on the system and check if it helps. To do this, follow the steps below.
1. Open Control Panel and go to Power Options.
2. Click/tap on the Choose what the power buttons do link on the left side.
3. Click/tap on the Change settings that are currently unavailable link at the top.
4. If prompted by UAC, then click/tap on Yes. 
5. Ensure that Turn on Fast Startup is checked.
6. Restart the computer.
