So I live in Australia, but from the U.S. therfore I have transformers threw out my house to make my american appliances work. I had my pc hooked up to one of the transformers so the power supply switch was set to the 115 position. Well I just got back to my house from my 20 day vacation and switched my computer to 220 volt power, but I did not switch the power supply switch. SO I push the power button and seen the flash through my top window and heard a pop. Followed by the wonderful aroma of burnt pc parts. So what all could have fried. I am hoping for best case just the power supply. Is it possible that I took out the mobo and chip also?
