Welcome to HP Forums. This is a great place to get support, find answers and tips.
I understand that your Notebook is not booting up and the OS seems to be corrupted.
I'll try my best to help
You can try a System Recovery to Factory Settings
- Turn off the computer.Disconnect all connected devices and cables such as Personal Media Drives, USB drives, printers, and faxes.
- Turn on the computer and repeatedly press the F11 key about once every second until the Choose an option screen is displayed, and then continue.
- On the Choose an Option screen, click Troubleshoot.
- On the Troubleshoot screen, click Recovery Manager.
- Under Help, click System Recovery.
- When Recovery Manager prompts you to back up your files, select a backup option:
- The Welcome to HP Recovery Manager screen is displayed. Read the on-screen information, and then disconnect any connected devices and cables, such as Personal Media Drives, USB drives, printers, and faxes.
- Remove media from internal drives, and remove any recently added internal hardware.
- Click Next to continue.
- When recovery preparation is complete, click Continue to proceed to the installation phase of the recovery process. The computer restarts several times during the recovery. This is normal. Do not close, shut down, or disconnect the computer while HP Recovery runs.
- Recovery Manager reformats the Windows partition and reinstalls the original software.
- After the system recovery is complete, click Finish to restart the computer. Complete the setup screens and wait until the computer finishes the setup.
- Once the setup is complete, turn off the computer, reconnect all devices and cables, and then turn on the computer.
- Before using the computer, update and protect your computer by reinstalling any virus and security software that was installed before the system recovery.
- Reinstall any software programs that were added after purchasing the computer, as well as any files that were backed up.

It looks like you were interacting with @KrazyToad, but he is out for the day & I'll be glad to help you out,
I'm the Jeet_Singh & I'm at your service.
As I understand the computer shuts down after a min of turning on, don't worry as I have a few other steps which should help you resolve this issue.
To provide you with an accurate solution, I'll need a few more details:
Have you recently made any software or hardware changes on the PC before the issue started?
Does the laptop shuts down due to overheating?
Have you checked if the laptop shuts down in Bios?
In the meantime, let's try these steps here:
In the meantime, let's start off by performing a Hard reset on the Notebook:
Step 1: Performing a hard reset: A power reset (or hard restart) clears all information from the computer's memory without erasing any personal data. Performing a power reset might fix conditions such as Windows not responding, a blank display, software freezing, keyboard stops responding, or other external devices locking up.
Step 2: Boot the computer into the Bios screen and check if it shuts down.
1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the F10 button repeatedly
Once you are in the BIOS, leave the computer in the Bios screen for a while and check if it stays ON or does it shuts down. If the laptop shuts down even in the Bios it is likely a hardware failure.
Could you please respond to this post with the results of the troubleshooting for further assisting you.
Eagerly waiting for your response!
I hope you have a good day ahead,
And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.
