PC turned off abruptly and won't turn on

Hello everyone, I was watching a movie on my computer and browsing internet, then suddenly my PC just turns off. I tried to start the PC by pressing the power button. Nothing happened. So I turned off my UPS and turned it back on, and pressed the power button on the CPU. My fans and my gpu light up for a split second and turns back off. After that if I press the power button again nothing happens. I have to restart the UPS and then press the power button just to see my fans and gpu light up for a second. Is my PSU gone bad? Do I need to buy a new power supply?

Generally does indicate a bad PSU, but could be other things as well. Please start by listing your full system specs.

Reset CMOS first.

 

40GB of RAM. What's the configuration and brand and model of the RAM?

 

Motherboard BIOS fully up to date?

16gb x2

8gb x1

Please note that, this configuration has been going great without an issue since I got the extra 8gb stick a couple of months ago. 

Bios fully updated.

Update: tried to start the computer with the 8gb stick removed. Still the same result.

Is this the old yellow label non modular 850w Bronze? If yes, replace it. It's over a decade old and can be the culprit.
