PC shuts itself off after a few minutes (sh.itjust.works)

So this started one day when I shut the computer down. I went to start and shut it down that way.

When I turned it on again it turned itself off after a few minutes. Then it wouldn't turn on until a few more minutes, then it again shut itself off...

I thought I heard a clicking sound when it goes off, so I think it's the power supply.

So I order a new one, wait a week, a slow painful week. And then I install the power supply.

Same issue.

I bring my tech guy over and he plays with the settings in Bios and updates my Bios. It never shuts off in bios so we think it's fixed..

He has to go because he's a streamer and he has a tournament. So I rush him home and think problem solved.

I go to be with my computer, get her out of BIOS and after a few minutes she shuts off and doesn't turn back on. Same problem as before.

So now I'm at a loss. I have no idea what's causing my problem.

Please. If anyone has any ideas I'd love to hear it. I just want my PC back.

People saying cooler,

But if this computer was running fine prior, and you already replaced the PSU,

I say its motherboard.

It's a power issue, and its the power distribution on the motherboard. Most likely a capacitor is done for,

Motherboard or cooling.. Anyway to narrow this down?

Anyway to narrow this down?

yes. check cpu temperature. there are software utilities for that. if it starts rising after boot and keeps rising until the reboot, then you found the problem.

Hrmmm.. now she isn't coming on at all. So I can't. Damn.

Then it ain't cooling.

Or maybe it was, and now the CPU or something is cooked. You might see or smell evidence if you take it out.
