I would try a different PSU first before spending the money on a new chip.
You are getting part way through the POST (Power-On Self Test).
As each device comes on line there is more draw on the PSU.
If the PSU over heated when the fan stopped it could have lost one or two capacitors.
That would result in this type of behavior, look for bulging ends on the upright capacitors.
