hp g62-367dx won't boot

Powers up for like one second, screen shows 'press esc to enter setup', before you can do that it powers down

Had exactly the same problem on a G62-228 CA.

Do the following:

1.  Put a USB stick in the side and press Win+B while pressing and releasing the power button.  This will cause the laptop to try and boot from the USB key and recover its (probably corrupted) BIOS

2.   If the laptop and the display stay on, and the display should then read "BIOS recovery" writing . . .  and then verifying . . .  then "press enter to continue"  then it will shut down.

3.  The very next power up should result in the laptop staying on and showing a screen stating "BIOS recovery successful (or something like that) code 500.   If it does this, then press enter and MAYBE (for me it was approx once every 4 or 5 attempts) it will actually boot into windows.

4.  Now download the correct BIOS software for your model (make sure it is the correct one for Intel or AMD).  This should be a file called something like sp52598.exe  Save this to your desktop and then run it.  It will laod a utility called "Insyde" which will write the new correct BIOS to your flash memory to overwrite your corrupted BIOS.

5.  Your computer should now be OK.
