Computer randomly turns off?

[OfficialZeno]

I have this issue where I boot up the computer like normal, and everything is fine. Then randomly, my monitor goes to no signal, keyboard turns off, and my mouse stays lit. It turn's back on after a minute or two. This is completely random, and I have no idea why its doing this. If you need any info or specs let me know.

 

OS: Windows 10 64 bit Home

 

Thanks.

Might be an overheating issue, just check that all of the fans in your system spin.

All the fans are spinning, temps look fine under 40°C. I'm speculating it's my PS4 controller plugged in? I've had issues when booting up the computer, and the PS4 controller doesn't let it boot past the BIOS screen until I unplug it.

Possibly, try keeping the PS4 controller unplugged and experiment around with that. If that is the problem, you might want to get a different kind of controller if you even need one.

Could you list full system specs? I'm thinking this might be PSU issue.

It's never done this before...

it's the PSU

this is common with PSU's that have s**t capacitors and are unable to send the correct voltage to power the system,

if the PSU is still under warranty, send it back and get a better one

the MB also can be problem

one system i have had both the PSU and MB unable to stay online for more than 2 mins

if you have another PSU, try that with your system and see if the system is stable enough to stay online for at least 24 hrs or more if you can

do the same with your old PSU with a different system and see if it can stay online for at least 24 hrs or more if you can

I don't understand how it could be the PSU when it only happens once? It happens when I turn on the PC for the first time of the day, and it never does it again?

capacitors store energy and can also filter it as well

when they get full they start to flow out excess with a stable flow of power, when they go bad this flow destabilizes and eventually it will act like the capacitor is no longer there

Is there a way I can test that this is the issue instead of just assuming it?

Use another PSU.

without taking apart the PSU and desoldering them, no...

also don't do yourself, it's high voltage and will kill you if you aren't careful!

I just can't imagine it being the PSU because it works fine all day with any interruptions. The computer doesn't fully turn off, it just sometimes basically restarts. It seems to happen when  my PS4 controller isn't plugged in. I've had issues with my PS4 controller causing my computer not to boot past BIOS. Weird.... I guess I could try swapping the PSU.
