@chintan84 check G3H and S5 rails, if all present work up to S4, S3 then S0. If just PP5V_S0 is missing and all other S0 rails are present, look into the circuit which generates PP5V_S0 to make sure all inputs are present and nothing is off.
Beyond this, it is up to you; I can't help you further without seeing the issue myself :)

@Reece can you tell me if PPBUS_G3H is present at one circuit do I have to check for all circuit if its present or not as per the board view?
@chintan84 if it is in 1 place it will be in all, unless a trace is broken in a certain area. Check the power rails, find out what is missing and work it out from there. Like I said, it's not really possible for me to help beyond that, it's up to you to figure it out
