i got a odd one for you all

[zenith anvil]

i got a odd one for you all so my main pc that has a rtx 4070 super 64gb ddr4 ram intel i7-14700f cooled with a AIO keeps crashing and sometimes all screens go black and all the fans ramp up to max speed even gpu dose aswell but i have checked all parts outs in another pc and they all work fine and its not a software problem coz i also reset the pc and the problem still happens and i can't figure it out for the life of me

[chilly sleet]

I’m willing to bet your cpu is fucked

Ever updated the bios?

[zenith anvil]

Nope tested in another system

[copper geyser]

When does it crash, is it random or when doing a task?

[chilly sleet]

You’ve just stated all parts work fine and all software works fine. That would mean you have no issue.

When did you last update the bios? This is very important for your CPU

[zenith anvil]

It can be random its crashed while just watching vids or just on the web but mostly when on games

[zenith anvil]

Yes all parts work fine and there is no software problems and I can't remember when I last updated my bois

[chilly sleet]

Then your cpu is fucked if you’ve never updated the bios

[zenith anvil]

I have updated it just don't remember the last time I have

[chilly sleet]

It’s a known issue due to power being supplied to the CPU and voltages go further than what the cpu can handle

If you haven’t updated it recently. You’re killing it still

[zenith anvil]

Well I'm gunna have to see if there is a new update then for it

[chilly sleet]

Damage is done

[zenith anvil]

But it can't be my cpu tho as I have tested it in another system and it works perfectly

[chilly sleet]

Define tested? You dropped it in turned in and then back out again?

I have packed my pc up for now but there’s some people here that can help you diagnose with it. Think @spring basalt is very good with working this one out. But yeah if you’ve let your 14700f just set its own power for 2+ years and not updated (or many times even if you have updated) bios… 99% rest assured you just need to RMA the cpu. Get a new one and update bios

[zenith anvil]

I got another system here and i took each part out put it in my other system stressed testing each part and they came back good so there nothing wrong with them

[chilly sleet]

Tested HOW

Did you run aida? Occt?

[spring basalt]

Screens going black and fans ramping is virtually always the GPU crashing.

Run DDU and then grab the latest driver from Nvidia. https://rtech.support/factoids/ddu/

Their drivers have been quite bad for the last 6 months so if you have still crash try this driver (DDU again): https://www.nvidia.com/en-us/drivers/details/237719/

If it still happens, a faulty GPU would be my main suspect.

[zenith anvil]

I have done this and its a still happened and I put it in another pc did what I normally do and it still works normally so its not a gpu problem

[chilly sleet]

Okay so as you’ve stated everything works fine in another system. No supplied tests on what you did. Replace the motherboard.

Only thing left it can be

[zenith anvil]

I got a spare mobo and tested and its still bugging. This is a really odd case and its doing my head in

[chilly sleet]

Well you’re doing something wrong

[zenith anvil]

I'm not tho that's the problem i have took it to a shop today to see if there is anything I.missed

[frank cosmos]

is the psu enough for the pc?

[zenith anvil]

850w

[frank cosmos]

model?

some are garbage and will fail easily

[zenith anvil]

My psu is a MSI MAG A850GL 850w 80 plus gold fully modular

[frank cosmos]

well thats not the issue

psu calculator says you should be fine

[zenith anvil]

I know

[frank cosmos]

might be malware, have you tried replacing the drive?

if that doesnt work try ram and if that fails i got nothing

[zenith anvil]

Did a full reset on the system

[zenith anvil]

I have also tried new and old ram that I had around

[supple jasper]

undervolt gpu

[zenith anvil]

Already done that

[spring basalt]

@zenith anvil I'm on a different server where we focus on tech support and we made a tool that gathers a bunch of logs from Windows and shows system info. If you want to, we could try running that and see if we find anything. I completely understand not wanting to run random software, but tag me if you want to try it.

[zenith anvil]

I took the pc to a shop yesterday I think it was coz i can't figure it out so I'm hoping the shop has a good shot with it
