파워서플라이 불량입니다. 다행히 혼자서 사망했네요. 간혹 터지면, 연결된 장비가 같이 죽는 경우도 생깁니다.
I used it well until yesterday, turned off the computer and left work, but it doesn't turn on the next morning. On the phone, I told you to check the parts that users can take out and plug in, and check if the "electric wire" is plugged in well, and check the on-off button on the back of the power system. (It's a basic thing, so I sometimes forget while consulting.) I'm sure you've checked it out. It's always written in F&A in the product manual of a large company, but I sometimes forget it, like a reminder that no one reads it.)
The main inspection points that you can check at home were checked and the power lines of the computer were also provided for the interior. The wire defect rate is not that high, but when the computer is not turned on, bring the power wire with you and you can check the power wire as well.

(1) A cable that causes poor connection due to an internal open circuit due to a bent power line.
(2) In case the sheath of an electric wire is peeled off by pulling the power wire;
(3) Non-standard power wires - power wires that are loose and frequently disconnected
(4) Other power wires burst
The internal state of the powerfly on that computer. Although it was an old product in 2015, I could see that one of the condensors inside swelled up. It's been a while since I saw a product with a burst capacitor, so I left a picture. I don't know since when, but I think I've rarely seen a main board or a powerfly with a burst of capacitors among computer components. (Power below is 2015 low-cost)
Computer Powerfly doesn't turn on in the morning.
Capacitor burst
The video below is about a faulty powerfly. The power tester is not responding when the power wire is connected and powered on. => Poor power
Fold/Stretch
Initial defective powerfly (defensive to powerfly tester)
However, the power tester cannot load the powerfly and can only measure the simple voltage, so there are some powerfly that are not actually connected to the computer, even if the normal figure appears. (The power tester is for simple action and you should consider it a device that detects defects rather than normal power.)
I think the power fly below was the power fly above. (Uploaded after a few days.) Even if this normal figure appears, sometimes when the power button is pressed, it "picks" or turns off at all.
Fold/Stretch
Power tester says it's normal, but it's defective power supply (1)
