PC is randomly crashing(without a blue screen just shutting down) but the components will stay on and fan speed increases.

[lyoung]

So after putting my components in a new case and getting new fans, my PC will randomly crash.
When it crashes, all components stay on but lose connection to my monitor. Is there some type of fix or do I need to buy another PSU or motherboard? Thanks.

Sorry but you have post on a tech forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Is the computer a custom build or brand name such as Dell or HP, if a brand name, provide the model name or series number (not serial) if a custom build post the brand and model name or number for the CPU, MB, the RAM ( including the amount, number of sticks and speed ) add on video card if one is used and the PSU (power supply unit) providing these details will enable folk to better help you.

Okay sorry about that, I have a custom build with a Ryzen 9 7900x3d, Nvidia 4070ti, two sticks of ddr5 ram that run at 5200mhz, an arous motherboard( basic size for a case), and a corsair aio. I also have eight lian li fans in my system and my psu is a gold-rated corsair with 850 watts. Hope this helps it keeps happening more frequently now, like every 10 minutes.

Also, sometimes the pc runs fine for a while whether that’s gaming or just browsing. What I think the issue is is my psu. All my other components stay very cool and never overheat with my PC being very new as well. The psu is rated gold standard and an 850 watt but I’m not a big fan of corsiar products. All my fans including the GPU go full power when it crashes. Very strange and didn’t happen once when I had my components in a different case. Also id like to mention that I not only go a new motherboard for this build but 8 new lian li fans so maybe I just need a better psu.

What is the the model of the Corsair PSU?

[lyoung]

It’s actually not a corsair it’s a thermal take gold 850w fully modular power supply.

[phillpower2]

What is the exact model of Thermaltake PSU, they haven’t made a decent unit for years and some of their units are so ba you wouldnt trust them as a doorstop.

Regarding the title of your thread, some clarity;
PC is randomly crashing(without a blue screen just shutting down) but the components will stay on and fan speed increases.

Software such as Windows can crash and when it does crash you get a BSOD and when enabled a crash dmp is generated, programs or games when they crash can on occasion close to the desktop but the computer will still be 100% functional.

Hardware failure such as a weak power supply and/or overheating are not software related and when a computer for example suddenly turns off, freezes or the screen goes black etc the behaviour should be described as the “computer shut down unexpectedly” or froze etc and not as having crashed as the latter implies a software issue as opposed to an obvious hardware issue when described properly.

Having the correct info means that helpers will not be looking for a software issue when the problem is clearly hardware related.

Your thread description is typical behaviour of a computers hardware not getting adequate power down to the PSU being too weak and/or overheating and being that Thermaltake PSUs are not the best the two go hand in hand.

Not sure how you got Corsair and Thermaltake mixed up, Corsair are one of the top while Thermaltake are near the bottom.

You have a decent CPU that is capable of high end gaming, suggest that you physically remove the 4070Ti from the PCI-E slot on the MB and hook your screen up to the appropriate video port on the MB and then test the PC by using it as you normally would.

Two things to mention, adding more screens and having the Windows Power Plan set to High or Ultra Performance both cause higher temperatures than normal so when trouble shooting both of these need checking.

Okay, my model of the thermal take I own is the Tough power GF3 850w PSU. Also, I’m sorry for saying it’s more of a crash, it’s exactly what you said it was, more of a random shut down and all my fans start going 100 percent. I believe it could be my power supply as I have never had this problem before and none of my components are old whatsoever and stay cool the entire time.

[phillpower2]

No worries, we have similar with some folk referring to the actual PC as their CPU and that can be real confusing.

Can`t find the results for the 850W version of your PSU but the 1650W version is only rated as – Tier B • Mid-range as are the GF3 range in general here it does have its pros but too many cons if you read the review here

Have you done the test and checks that were suggested.

[lyoung]

Okay thank you very much, I currently am trying a test right now. As of now, my computer runs just fine without the graphics card, with no random shutdowns and the same temps. This leads me to believe even more that it’s a PSU issue as it may not have the capabilities to power my GPU without failing. And as for changing my settings to balanced in windows, that’s not something I really want to do unless it makes no difference what it’s on. I’d be fine with getting a new PSU and can afford one. I just want to know if the issue is being directly caused by my PSU.

[phillpower2]

You are welcome but before 100% writing off the PSU see the below;

Before replacing anything it is always advised to get the GPU checked, this either by swapping in a known good PSU that has the required output and efficiency or by having a local tech test the card.

Regarding the rest of your reply;

Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues and a weak or failing PSU will get hotter and weaker the more that you use it which in turn leads to the sort of behaviour that you describe.

To best power the GPU have you been using the PCI-E 5 cable that shipped with the PSU.

Nothing further from the OP so marking thread as new PSU resolving issue,
