All this would do is supply 3.5v to the main board, the power supply will never operate without the standby circuit working first. The standby circuit also supplies vcc to the other ic's on the power supply.

You have a schematic that have the voltages. Just go around that IC and check for wrong voltage.
I assume no responsibility for any stupid suggestions I might post.
