Replace all electrolytic capacitors in power supply section on mainboard. caused by poor quality lower voltage caps being used in powersupply. Problem will reoccur every 2 to 3 years if 105oC caps are not used. If mainboard is replaced with new mainboard problem will reoccur within same timeframe. Fix old mainboard using higher voltage and higher temp caps and problem will be gone for good.
