My neighbor plugged her PC on the 220V mains without changing the power selector switch on the Power Supply from 115V to 230V. She called me saying there was an explosion in a faulty adapter she was trying to use when she was setting up her brand-new computer, but she did not tell me she had actually fried the PSU. Ignoring that, I switched the power supply to 220V and when I plugged the cord in the mains there was another explosion-like sound in the power supply.
My question is:
Why may the PSU have blown twice if it was already dead the second time it was plugged?
May have this accident cause damage to the motherboard and or CPU?
Thank for your help in advance,
Osmany
