Pc shuts down and fans go full blast with low hardware temperatures.

[Radeho]

Hello,

I have been struggling with this problem for a few weeks now. It first started when I was playing a game and my pc shut down, screen went black and the fans went 100% speed. The first thought in me was a temperature issue, so I cleaned my whole pc of dust and put new thermal paste on the cpu and the gpu processor. This did the trick for 2 days and it then did the same crash again. I then changed the msi afterburner with a higher fan temperature graph, this worked a few days aswell, but then crashed again. I ordered 2 more fans to put in my case and a new pair of ram, because I thought this may solve the problem if it lied with the ram. Then strangely when I put the ram on xmp profile 1 in the bios, what I think should be duable, the boot of that configuration did the same crash with black screen and fans 100%. As a last solution I put my mhz of the ram to 2500 and it worked for a day until the same crash happened. I immeadiately felt my pc parts and they were not hot or even warm, so I don’t think it is a temperature issue anymore. Now I have no idea what to do and have come here for your help. Do I have to replace some parts, fix some settings or just buy a new pc?

I also should add that whenever it crashes all the lights in the pc stays on and the red error light on the motherboard where it says cpu stays on and red. I think it should be a ram error then?

My pc specs:
I9-9900k
RTX 2070 8g armor
Z390 ud (I have heard that this is not a decent motherboard)
Bios: F10k
Old ram: G.skill tridentz rgb 2x8gb 3000 mhz
New ram bought for replacement: G.skill tridentz rgb 2x8gb 3200 mhz
Cooler master 212 evo
4 fans in case, 2 from nzxt and 2 from be quiet
A 650 w 80+ bronze psu (Don’t know the brand anymore)

Extra info: I have this pc for about 5 years I think and added the i9 in 2021.
I use this pc to game a lot and study on.
Began this year with editing some vids.

Hello More than likely it is your psu , you should have a gold standard psu with at least a 5 to 10 year warranty..

I am going to tag a member for more input..

The RTX2070 wants at least a 650w PSU, with sites like this; https://support.lumion.com/hc/en-us/...y-do-you-need- recommending 800w as they like to give a 150w leeway to cater for all the other power demands of the PC.

And without knowing your PSU brand, it may be a crappy one. It is Bronze so right off the bat, it’s not the best.

Any power supply unit certified 80+ Gold (or better) and offering at least a 7 year warranty (preferably 10), and you can’t go wrong.

For example, ThermalTake ToughPower GF1 or GF3 ranges, Cooler Master, Antec, Corsair RM series.

So, while a better PSU will help, it may also not be your issue, but it’s one of those components you should seriously consider replacing.

Let’s get your complete PC specs.
Get Speccy; Speccy - Download Builds
In Speccy, click File > Publish Snapshot (hit Yes if prompted to proceed with publish) > Copy to Clipboard > Close.
Now you can paste that link into your next post.

Speccy doesn’t show the Power Supply Unit so taking off the side cover and find the sticker on your PSU. Then let us know the brand/make/model.

Is Speccy safe?

Thank you for helping me! I opened up the back of my pc and could read where my psu is from and I made an mistake in the info and will edit that now, I have a Cooler Master MWE 650 Watt 80+ gold Model: MPY-6501 AFAAG. Sorry for the misunderstanding.
I did the speccy part you asked me to, but I have some concerns about revealing some data that is on that link like my IP address and other network information. Is it safe to post that link here? Is there another option without revealing my IP?

I will copy for now everything from specy here:

Let’s see what @phillpower2 thinks about that PSU.
I couldn’t find anything terrible in the Speccy report.

Any chance you can get your hands on another PSU - friend, family, work, neighbour?
And this only occurs playing games?

[Radeho]

I can maybe get the psu from my brothers pc and install it in mine. I am going to try that when I’m home in the afternoon.
The problem occurs after a few hours of gaming, just after 1 hour in google drive where I learn or when I boot up the system with xmp profile 1 or any other higher frequency than the base clock installed (it crashes immeadiately while booting). In short, it varies a lot when it crashes, but for the most time it happens after some time spending on my computer.

When it crashes: I have to hold the powerbutton until it goes off. If I press the power button on after the shut down, the problem occurs immeadiately. I then have to switch of the powerbutton to the psu and unplug the powercable, then I have to reset my CMOS in order to reset my bios. After saving the auto settings in the bios it boots up.

Seasons greetings folks

If still in warranty the PSU spec would be fine for this build, if not in warranty the PSU needs to be replaced as the symptoms described are typical of that which a weak PSU exhibits when overheating internally.
Power Profile
Active power scheme:[COLOR=rgb(184, 49, 47)] High performance

Change the Windows Power Plan to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues and a potentially weak PSU such as the one that you have will get hotter and weaker the more that you use it.

Restore the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" “most stable” or on newer boards “optimized” please note that if you have both the “most stable” and the “optimized” options in the BIOS you should choose the most stable" option as in this instance the “optimized” settings are a form of overclocking that can cause instability.

Save the new settings, exit the BIOS, restart the computer, test by using the computer as you normally would, post back with an update once you have done this.[/COLOR]

[Radeho]

I changed the powerplan to Balanced and Loaded the Optimized Default settings in the bios. There was no option called “most stable”, so I assume the “load optimized default” was the one. I have been gaming for 3 hours now without issues and crashes, I am very greatful to you guys!!! That setting from the active power scheme was done a very long time ago, so I forgot about that. Except know I am gaming on 2133 MTS and that causes a bit of a bottleneck for my performance so should I replace the psu and try xmp profile 1 again with a new one?

[phillpower2]

Leave the system exactly as it is for the next 24hrs at least, the bottleneck you will just have to put up with, better to have that than a PC that you cannot use.

If all is still stable after the 24hrs you should manually OC the RAM to the max that the CPU can handle at stock which is 2666MHz, not a fan of OCing so will just direct you towards the guide here which should give you some pointers.

[Radeho]

Ok very much appreciated! Now I know the cause of the problem and the solutions given worked. I’ve got the help I wanted, so for me this case is solved. I hope you guys have a Merry Christmas and a Happy New Year

[Bruce]

Will close as solved!
