I am not sure if they are the same, but something puzzling just happened. My dell precision workstation 2007 has been fine ever since, with many, many power outages over the years. But there is a time a guy pulled the power cable off, and a few days later the PC no longer boot, with loud whooss fan sound at startup. After testing, everything was fine, only the motherboard died, with apparent fried capacitors.
Can anyone please explain? Thank you.
