Please provide the details of what happens when you try to boot the PC.

Telling us it does not boot is not enough information.

Actually I was installing update on PC . Suddenly the monitor becomes disconnected from the PC,and white light starts blinking at the power button at 5 second interval .But PC doesn't start.Please help.

The light blinking is NOT good news. Was hoping this was a simple boot issue, but with that information, this sounds more serious.

These are usually Windows Update corruption problems but this does not sound like one

You'll probably have to do a complete reinstall to get it working again.

You can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC.

The recovery drive can then be used to install Win10 and the HP drivers and utilities that originally came with your PC.
