Strange power problem (desktop computer)

So I normally leave my desktop PC (specs below) on 24/7 but with the hot weather we’ve been having lately I’ve been running the air conditioning in my apartment a lot more than usual, so I thought to help cut down on my next electric bill, I would start shutting down the PC at night. The next morning, after the first night, my computer would not turn on.

I opened it up, unscrewed some things, and lifted the power supply up a bit so I could see what was going on (it’s pretty tight in there). The LEDs on the motherboard were on, so some kind of current was flowing. I tried the mobo’s “start” button, but it didn’t light up. However, I noticed that once when I did this one of the fans started spinning for only a millisecond and then stopped.

I’m not a computer technician, but have worked with computers for many years and have done things like changing BIOS settings, installing internal drives and fans, and replacing thermal grease on the processor. Nonetheless, I figured it wasn’t something I was going to be able to fix without eventually purchasing a new power supply. I left the computer plugged in, but flipped the “off” switch on the back of the device because I had an idea and wanted to see if it would work.

During this time, I was doing my work on my backup laptop. Several days later, I flipped that switch on the back of the desktop computer to “on”, and pressed the button on the front to start the computer … and it started. !

Obviously, there is still something wobbly there, but why would that work? Does the power supply have internal batteries that need to be recharged, or something like that?

Appreciate any ideas! 😉
