I have an old computer, it started to failing after 10 years I think. The computer doesnt turn on, i click The button and it does nothing, when i slide The I/O button to off, on The psu The fans starts and in The same second turns off. I already tried with other old psu, same watts but The other psu doesnt do really nothing. I wanted to fix but without wasting money, i know a New PC is better, but i already have one.
