Moments ago I was using my PC normally and I plugged in my phone. I was browsing its files, clicked on the option to sort them by date, and then the display, network and peripherals got disconnected and the PC begun making a loud fan noise and became unresponsive. I tried to power it off on the button but it didn't work. I had to unplug it. I let it rest for a while and tried again: same thing. Now it starts and doesn't even boot, just hangs in that locked state. There is a rattling noise coming from the fan and the power light flickers.
I've tried:
disconnected all peripherals and tried to boot
removed new RAM and put back old one (I upgraded recently)
replaced motherboard battery with a new one
checked the monitor
None of this did anything.
Recently (about a couple of months ago) I cleaned up this PC (ASUS M11BB-US001O) and installed new RAM (kingston KVR16N11K2 8MB *2, 16TB HDD Exos X16 7200 RPM 512e/4Kn SATA 6Gb/s). It was working perfectly well until today. The OS is debian 11. The disk is encrypted with LUKs (idk if this is relevant).

Until a few months ago the PC was just sitting there unused gathering dust. I got it circa 2017 and until the upgrades a couple of months ago I hadn't touched the hardware. Could it be the power supply?
To summarize:
The PC starts when I press the button but doesn't boot. There is no display.
The tray doesn't work, nor do any of the peripherals nor does it connect to the network
The fan works and the light turns on. The light flickers.
The noise it makes is normal booting noise. Not excessive or anything
There is a rattling noise coming from the fan that is connected to the power supply. This isn't new; I noticed it the first time when I upgraded the PC. It didn't seem to cause trouble so I just ignored it.
I did notice one major difference: before, as it booted, I could hear the new HD make some noise as it was being read. Now, nothing.
Help?
