if the chip is burnt it is possibly the symptom not the cause. In the PS circuitry the load is put on and probably overloads the chip capacity and blows it.
The quickest and most efficient method is to find a replacement PS. Not knowing the PC type cannot suggest a replacement. Provide this information and will try to assist.
