PC Randomly Shutting Down

[LewisJones28]

Hey Guys,

I recently built a computer my first pc about a month and a bit ago and it has been running good ever since. However, this weekend i've had a few issues with it randomly powering off after being on for 20minutes or sometimes a couple of hours.

Sometimes this'll be when it's under a bit more load, playing games, but then also had it when i was just staring at the BIOS screen, and then also surfing the internet watching videos etc.

I was looking at my BIOS today and looking at the monitoring section and looking at the power supplied to the components.

3.3v Voltage: +3.344 V

5v Voltage: +4.520V (sometimes turing red and falling into the +4.4~ area)

12v Voltage: +12.0V

I'm presuming the reason for it shutting off is to do with a failsafe as the 5v isn't receiving enough power to it.

My specs: https://uk.pcpartpicker.com/list/P3s6V6

I believe the PSU is a older one than in the build as I bought it off a friend who hadn't used it (p sure this is the one i actually have currently installed) https://www.corsair.com/us/en/Power/rm-series-config/p/CP-9020056-NA

 

Thanks for any help you can give.

 

edit 1: P.S. wasn't really sure where to put this thread so though this would be the most suitable

Is the motherboard making contact with the case in any way? It could be making it short out and shut down.

5V input should be within 5% of 5V at the very most, so 4.75V to 5.25V. I wouldn't be surprised if that was your issue.

I'm pretty sure i've got it on the standoffs, would'e thought this issue would've been a lot sooner as well rather than just now considering i haven't altered the motherboard at all since build.

yeah it does seem pretty low which is why i thought that of anything. Would this be an issue with the PSU?

It could be either a PSU issue or a motherboard sensor issue. You can buy a PSU tester for cheap online to see that is the problem.

more likely a mobo problem than PSU. could be a bios update fixes it, but I would be scared to do a bios update with a chance of the pc failing during the update. not sure if the tuff has bios recovery or not. have a disliking in Asus since my X99 systems all having some kind of issue. X99 Deluxe board, Rampage V and some other I can't remember costing around $800 Here in RSA

Only reason im favouring PSU aswell is that it was second hand from a mate who claimed it was basically never in use but it is an older model which could effect it? IDK i just don't want it to be mobo as that's a lot of effort to replace lmao

can you borrow a PSU from anyone just to test it out? if it is the PSU your problem should disappear then right? I have a PSU I've been using almost non stop since 2012 / 2011 maybe can't recall. and mine is a much crappier brand than Corsair. But if dust was a lot and the PSU was sitting idle. it might have made a capacitor too hot and it popped. easy to replace for someone like me, not something I'd recommend to someone inexperienced with PSU's & soldering though. Best bet is to try and borrow a PSU from someone. if the problem persists it's likely the Motherboard. One thing I'd recommend doing before going through all this trouble in the first place is just reseating the CPU cooler since it might not make good enough contact with the CPU and that is throttling the CPU and eventually shutting it down.

I'll see what i can do in terms of borrowing a CPU. I feel like the cpu cooler is okay, i've never had performance issues. CPU temps sitting at around 35 degrees with gpu at 45-50 at idle. Which im pretty sure for the spec is pretty normal.
