Hi@Rohit73,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing issues with the HP Pavilion Desktop PC not turning on. I apologize for the Inconvenience.   

The BIOS can be corrupted during normal operation from a failed BIOS upgrade, or damage from a virus.   

Recover the BIOS using a key press combination. 

Turn off the computer. Press and hold the Windows + b keys, and continue to press those keys while you press and hold the power button for 2 to 3 seconds. Release the power button, but continue pressing the Windows + b keys. 

The power light remains on, and the screen remains blank for about 40 seconds before anything is displayed. You might hear a series of beeps (usually 8 beeps). Eventually, an HP BIOS Update screen is displayed and the BIOS update begins automatically.

After the BIOS is recovered, a Continue Startup button is displayed and a timer counts down. Click the Continue Startup button to restart the computer immediately, or wait for the computer to restart automatically when the timer reaches zero.

If the issue persists then it could be a hardware issue. I would request you to contact our HP Support Engineers and should be able to sort this out. HP provides repair or service options for out of warranty products as well. Hence I encourage you to contact HP support for all warranty service options.
