My PC just stopped working and I can't figure out why. There's absolutely no feedback to pushing the power switch. I feel like I tried everything the internet recommends, made sure the button works (it does, and so do the connected pins on the MB), held it down for a minute with the PSU unplugged, shorted the power pins manually, re-plugged all the cables, changed the CMOS battery, tried turning it on with just one RAM stick at a time.

I'm out of ideas.

    PSU is most likely blown.

    Unplug everything, short pins 14-15 on the mobo connector, see if PSU comes to life. If not, dead PSU.

    If it works, plug everything back in one at a time until the problem comes back. When it does, you've identified your dodgy component.

    @AlmondSauce Will try tomorrow.

    How am I gonna short the pins though? with the cable unplugged from the mb as well?

    @DustInCompetent Yup, unplug it from *everything*. Then you've just got a bare PSU you can test.

    @DustInCompetent
    How: Paper clip

    On youtube type in: "Corsair PSU test" First video

    Try this. It's an official video from Corsair. Just make sure to be save, i wouldn't touch the paperclip and just turn on the psu and take a step back. Make sure to not wear anything metal and inform yourself on the internet because I sure as shit don't know anything about electronics. If you don't have a failsave in your home electronics that pops out once there is a short circuit you could seriously injure yourself or even fucking die. If you get a big zap, go to the fucking hospital. Heart fibrillation is no joke. Sorry for all the fucking.

    Check that the power outlet you are using is working (don't use the paper clip for that)

    @AlmondSauce The PSU works when I start it like that, even with everything else plugged in. Looks like the motherboard just fails to ground those pins, guess I'm gonna have to get a new one :/

    @Mark-Zuckerberg I can't believe THE Mark Zuckerberg made an account just to comment on this post.

    I found a similar video for the EVGA PSU I'm using

    I had the exact same issue, the PSU is either not getting enough ventilation (in my case a teddy bear someone put there) or then later on a another PSU swapping it out worked just fine again.

    My PC just turned off, no blue screen, no error message not even an even in windows event handler. I also had to switch the PSU off, wait for about 10 seconds and flip it back on again to make it work

    My PSU was a bequiet (I think 650W, not sure tho)

    @Mark-Zuckerberg
    Christ kid, millions of people have been using the paperclip test for 30+ years. It's the recommended methods in most instruction manuals.

    Do you have any real experience to impart or are you just here to spread FUD and sling logical fallacy?

    @Mark-Zuckerberg something is seriously wrong with a computer psu if you get something out of its cables that kills you. As long as you're not poking inside the psu you should be fine.
