F2 should bring up HP PC Hardware Diagnostics (UEFI) at startup, but it only changes my brightness

Hi there! My HP shuts down at random times when I'm multitasking (watching a movie while playing a game). It just stops. So I went to my HP troubleshooter and it says to shut down, start up while pressing the F2 key every second
until the HP PC Hardware Diagnostics (UEFI) shows up.
Instead, it just changes my brightness on my screen. Is there another way to bring up the system test?

Many HP computers have bios UEFI diagnostics.
Repetitively click the F10 key on boot and then navigate the menu to system diagnostics or UEFI diagnostics.
Run the diagnostic test in extensive mode or loop until failure mode overnight.
Report in the thread which hardware diagnostic steps you were able to run and the results.
This may allow us to rule in/out hardware problems.

In case you do not have HP diagnostics create a bootable UEFI diagnostics flash drive:

Are the files backed up?

To boot to windows troubleshooting options please find another working computer.
Using a flash drive create a bootable windows 10 iso:

Download Windows 10

For HP computers use the F9 key to boot to the windows 10 iso.

Once you have the bootable windows 10 iso you should be able to boot to the windows troubleshooting menu providing more options to repair operating system/registry problems.
