I built this PC several years ago, and had zero issues for the first few years of useage. Lately however I have been encountering an issue where my PC will not turn on. I know this has something to do with the power supply as my GPU has a power indicator LED whitch is always on when it has power. When the PC is powered on it functions as normal and does not lose power. It may fucntion as expected for hours, days or even weeks between issues. I have tested the PSU by shorting it with a paperclip, PSU powers on as expected. I further tested all the pins on the 24 pin ATX connector using a multimetre. Again, everything worked as expected. I am at a loss to explain the intermittent power loss, there does not appear to be a discernable pttern.
