[SOLVED] My desktop PC when turned on today, after a few seconds shut down

Hello

Today my computer which I have more or less since 2015 or 2016 when I turned it on, then after 3 seconds it shut down immediately.

I waited a minute or two, turned it on and it works fine

But I am afraid that it happens again.

Does this means maybe the power supply is dying?

I think I have Corsair 750w platinum modular, dont remember the exact reference, but the computer has 4-5 years running smoothly.

No way of knowing. May never happen again might happen the next 15 times you boot.

that doesnt help much, can I diagnose in some way a power supply?

If it's working properly now not really. You can run occt if you want
