[SOLVED] Pc shuts down at random

[Nem95]

Not sure if it’s linked to power supply but my pc has been shutting itself down at random and I dunno how to work out what the problem is as I know there could be many factors

Please post specs ?

I think its the PSU

 

[Vic 40]

I agree, with parts like that would you want a good quality psu.

Does it also happen with the RX 5700 XT out?

 

[Brokenthusiast]

I have a corsair cx750m PSU, which is terrible, and was experiencing similar shutdowns. I have an i7-9700k at 4.7ghz, rtx 2070 and corsair vengeance ram at 3.2ghz. PC would work perfectly, no issues AT ALL and then randomly boom! Full power off, followed by a restart. The issue ended up being that, for whatever reason, the automatic voltage control on my MSI mobo was not stable. SO I used a static overclock (not auto) and static voltage. It should be noted that I put slightly more voltage than was required for some at 4.7ghz. I also made sure my ring ratio was optimal, which for some reason it was NOT (was higher than processor clock speed). I lowered my graphics card overclock as well because it crashed 3 weeks after I applied the aforementioned BIOS fix. It has been a month so far, no crashes, gaming great. Hopefully you figure it out. This forum helped massively, even though most threads blamed the PSU, thankfully that wasn't the case.

It’s definitely not the psu as wasted money on a new one and it’s done the same thing freeze and then shut down it ran for about 50 mins before shutting down unfortunately I’m not very smart when it comes to pcs as wouldn’t know what to try next

 

[Vic 40]

Asked already, does it happen with the RX 5700 XT out as well?

The 4x8gb of ram didn't come as one kit. Try and test with two sticks that came together in one set.

Should I test with just graphics card out first or both card and ram

 

[Vic 40]

One at a time, would test 2x8gb ram first, make sure they were from one set.

 

[Brokenthusiast]

Test ram. Once you’ve ruled out the ram and any memory errors, check your BIOS. Seriously. Update your BIOS. Make sure the CPU voltages and clocks are stable. Remove any “auto” settings on cpu voltages and clocks and replace with the correct stock voltage/clock. Check for crashes again. It could easily be that the automatic setting on that mobo isn’t providing stable voltages to that processor regardless of the power supply. After you’ve done all that, and the computer is still rebooting, update your graphics drivers and check for crashes with and without the graphics card.

 

[Nem95]

Ram tested I used memtest 86 no issues with any sticks I suppose next step to test updating bios and check voltages being stable if the fails take the gpu out as suggested by vic 40

How will I know what to turn off from auto and what setting to put on instead of auto Iv updated bios and it still shuts down and how do I know it’s at a steady voltage as I’m not very good with checking all this stuff out 😅

 

[Vic 40]

if the fails take the gpu out as suggested by vic 40

Tried this already?

 

[scout_03]

what is the age of those hdd drive specially the 80 gig on .

 

[Nem95]

Currently trying my old gpu in it and going to see if it stays on as think the amd drivers could be the problem as seeing others experience similar problems

Not entirely sure as was out of another pc my sister had a couple years ago could be quite a few years old tbf

That does not sound like a PSU issue. Did you replace the PSU and the problems went away?

And in what alternate dimension are there people saying that the CX750M is a terrible PSU?

Not the OP but someone with similar problem who wanted to tell how he solved his problems and maybe help the OP with it and if you've read all does he say it wasn't the psu in his case.

Hope for you this will give a solution or at least some insight in the problem.

I know. But he never really even said that he found out the PSU was actually the problem! So how does that help?

He says, "PSU is garbage. Everyone told me it was garbage. I did a bunch of stuff that has absolutely nothing to do with the PSU and now it works."

Come on.

 

[Vic 40]

I know. But he never really even said that he found out the PSU was actually the problem! So how does that help?

Basically does he say that his motherboard was the problem not the psu. Thinks he wants to let the OP know that manually setting voltages and some other things (ring ratio he mentiones) might help.

He says, "PSU is garbage. Everyone told me it was garbage.

Why he says his psu is "terrible" i don't know. Maybe he has read alot of old threads here or someone told him in his own thread (which i guess he had). In some of the old threads from the time the CX was stil green/black the psu got blamed. Whether that was right or wrong is another thing.

We are kinda getting this thread of topic since he is not the OP, if you want to know what he meant maybe PM him?

The OP has a VS650 with an RX 5700XT+ i5 8600K, maybe not the right choice of psu for it although it is technically powerfull enough. Still not sure though if this might be the problem for him, might be as well motherboard. Always hard to say without swapping parts.

Update doesn’t matter if the gpu is out as I put old one in and it stayed on for a while now it’s shut it’s self down probs going to have to take it to a professional to look at it as I’m out of ideas

A professional is going to cost more than a new PSU.

If it's shutting down, it's probably the PSU.

How old is the VS PSU? You didn't list the part number for it.

Is it this one: https://images.frys.com/art/product/big/9510702.01.big.jpg

Or this one: https://www.corsair.com/corsairmedia/sys_master/productcontent/CP-9020172-NA-VS650_PSU_01.png

The psu I replaced is the second one which is not in the system now I’m using a different one now which is this one https://www.amazon.co.uk/gp/aw/d/B01H78DL76?psc=1&ref=ppx_pop_mob_b_asin_title

Sorry. Missed the part where you bought another PSU.

Yeah, the second of the two VS's I listed is the good one.

With this one it stil shuts down?
