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
@micolithe I didn't have like a shim or tool I felt comfortable shorting out the connectors with so I just said screw it and ordered the PSU and a new power cable for $30 off eBay, if it works then Yay if it doesn't might try dropping it off with a local repair shop and then if they can't do anything it's a new(ish) used office PC off fb marketplace :p
