Hi @SS132,

Welcome to the HP Support Community

I understand you are facing a Boot-related issue with your HP Notebook. Not to worry I will help you to get a resolution to resolve the issue.

Lets' try the below steps:

Crisis BIOS Recovery

1. Turn off the computer, and then connect the power cord.
2. Press and hold the Windows key and the B key at the same time, and then press and hold the Power button for 2 to 3 seconds.

1. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

• If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next section to Recover the BIOS using a USB recovery drive.
• If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for only 2 to 3 seconds.
• If a BIOS recovery message repeatedly displays, continue to the next section to Recover the BIOS using a USB recovery drive.
• If a message that the computer improperly shut down or a boot problem is detected displays, follow the on-screen instructions to resolve the error.
• If Windows starts, update to the latest BIOS version. Go to HP Notebook PCs - Updating the BIOS for more information.
  The HP BIOS Update screen displays and the recovery begins automatically.

Possible problems:

  - motherboard issue

Ryzen notebook can produce this issue. If this is a ryzen pc, and fan replaced before, probably a motherboard issue. 

  - Overheating issue

When your heatsink is defect, can power off on startup or use. If before it was in service for replace fan, probably is a sneaky motherboard problem.
