Hi, i got this pc from a friend that i know and the powersupply didnt wnat to turn on the pc so i tried it myself and it didnt work, but i ddi notice a little sound coming from the powersupply (And yes i know it's from the powersupply since i took it out and it was coming from there.) but only when it's jumpers are plugged into the motherboard. and i did try the paperclip trick and the fan does turn on but doesnt when plugged into the motherboard and pressing the power buttom. I also tried an other working powersupply and it worked fine but that power supply i need for another pc that i use. No fans or anything turns on.
