Hi I currently have a computer set wit the motherboard and cpu and powerbox and everything else. I brought it from overseas witout the atx case. i started the computer without a case and with the old powerbox i bought, it seemed to start. So i bought a new atx case. the case had it's own powerbox. so i didn't bother to use the old powerbox. the old powerbox shows 150-230voltage on the side sticker while the new one shows 240+ voltage on the side sticker. i didn't notice it at first and started the pc and everything turned on and off instantly. the motherboard light dont even turn on. the powerbox fan doesn't even run and it doesn't even supply to a cd-rom. i tried the old powerbox then amazingly it doesn't work either. i thought the motherboard doesn't work no more but it seems the both powerboxes new and old don't even start their fans now. someone plz advice what should i do. i am afraid to use another powerbox thinking it will get wrecked too. plz help as soon as possible
