So a month back I built a custom desktop. At first it was working great, but lately it's started acting up. Often, when I try and turn it on, it doesn't. However, occasionally it will turn on randomly. It tried checking if the power button was broken (by connecting the pins with a screwdriver) but while I was at it I adjusted the PSU cables and that seemed to fix it. Unfortunately, it just turned off and is not turning on at all. Any ideas?
Thanks
