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.

    Wonderful day!

    The click sound may not be related, if the same click happens when you shut it off via the power button.

    Just to clarify, have you tried disconnecting everything from the motherboard except the RAM and try powering it on to check the time it stays on?

    Also, do fans spin up fast right before it shuts off? For the “CPU temperature” mentioned by @14th_cylon@lemmy.zip in the comments, too.

    The few ideas what may cause it are:

    - 1. Overheating at some motherboard or PSU itself?
    - 2. The storage drive malfunctions;
    - 3. Memory gets malfunctioned; here, I would tried other RAM and/or try changing the sticks one by one.
    - 4. It may come from the dedicated GPU malfunction, too, of course.

    As mentioned, please do try experimenting with all the devices disconnected from the motherboard except the PSU and memory, since it may come from the peripherals where the motherboard or PSU shuts the whole machine off to prevent further damage.
