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.


Disagree.
If their computer was running fine previous, and there’s not a huge buildup of dust/dirt (which should be obvious),
It’s the motherboard failing to deliver full power to the CPU when it goes to draw a load.
Motherboard cap’s fail just like PSU’s do.
the fact that their computer was running fine previously does not mean it will run fine until the judgement day. stuff breaks and any stuff that once broke “worked fine” just a second before.
Honestly, I kind of suspect a clogged or failed AIO cooler pump … but I don’t know if OP is even using an AIO cooler.
