Hi @Avinash_1234

Welcome to the HP Support Community. I'd be happy to assist you with the PC issue. 

Let's try these steps -

Step 1 Hard Reset - 

1) Shutdown the computer.

2) Unplug all the Adapter and peripherals connected.

3) Remove the Battery.

4) Press and hold down the power button for 15 to 20 seconds.

5) Plug-in the Adapter and put the Battery back into the computer.

6) Try to turn on the computer.

Step 2 Hardware diagnostics -

1) Hold the power button for at least five seconds to turn off the computer.
2) Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
3) On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.
4) Click Extensive Test. 

If the hardware is fine, I'd suggest re-installing the operating system. Back-up the data and try these steps -

1) Shutdown the computer.

2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.

3) Press F11 once for System Recovery.

4) Choose the Keyboard Layout.

5) Click on Troubleshoot.

6) Go to Recovery Manager and click on System Recovery.

Note : Back-up all your data as System Recovery will delete everything that you had saved or installed on the computer.
