My dad wants me to check out his PC that suddenly stopped turning on. It's a Dell Optiplex 790 I ordered him off the internet a few years ago, swapped in an SSD. I'm a bit out of my depth because I'm not actually very smart on the electronic principles side of things, even if you handed me a multimeter I wouldn't know how to use it or what to check. It *could* be the power supply going out, but if it is, I'd have no way to verify that... And if it is, it could've burnt out the motherboard...
@pendell if the power supply is ATX, if you bridge the single green wire to any black wire on the 24-pin connector, the power supply should start up, if it doesn't then it's dead, if it does start up then the problem lies elsewhere
@pendell apparently i found an argument that says the term is short (connect briefly) because if you bridge it and leave it like that it's the equivalent of holding the power button down so it'll just shut off again
