Acer Predator Orion 7000 – PO7-640 randomly shuts down. Event ID 41.

Hello. When my pc (predator po7-640) is on for a long time, lets say +7 hours, sometimes it will randomly shut down. When i look at at Event Viewer, it will show me 1 critical error. Event id 41. My GPU temperatures are fine but when i look at CPU temps, some cores will go up to 90° and i assume when it reaches 92°? or something close to that, it will forcefully shut down my PC to prevent any critical damage. I've googled to fix the issue many times and tried a lot of things and yet the problem still remains.

I believe my CPU gets too hot and this is why my PC randomly shut down sometimes, but i am not certain.That is why i am here looking up the manual. I've dissembled some parts to clean my PC as good as possible (although there wasn't much dust to clean after 2 years of usage) as a last resort. Now, i am just a PC noob and am nowhere near knowledgeable about the hardware and stuff like that, but, the only part i didn't trust myself to "inspect" further and clean it to the best of my ability is the CPU and the water cooling system around it. I've done some research and apparently the water does have to get changed every now and then.

Now my question is, could it be that the overheating stuff happens precisely because i didn't change the water for my CPU cooler for 2 years? And thats why my CPU reaches over 90° celcius? Please keep in mind that i am not certain if it really is the CPU temperatures which shutdown my PC. But after trying a lot of different things online and assuming that it can't be the power supply since it is a pre-built PC and i never upgraded/changed anything in the specs, i think the problem lies in the cooling of my CPU. Also, one thing i didnt try was disabling C-STATE in the BIOS settings. I couldn't find the setting to disable it. I've read that disabling C-STATE did wonders for people with the same issue.

Here are some additional information:

Acer Orion 7000 Predator PO7-640Windows 11 23H2 (latest version + checked for updates with the windows update checker)

64-bit operating system, x64-based processor

Correct, Event 41 indicates interruption in the power supply or by a Stop error most probably due to overheating after 7 hours non-stop gaming. To mitigate the overheating of the CPU, take a coffee break once a while and shut down the Desktop (not suspend). Disable Fast Startup and Hibernate in "Change what closing the lid does" and in "Change settings currently unavailable", select Balanced Power Mode in Power & battery settings (see picture). Check in Task Manager what background programs are running (should be around 60) and uninstall all the pre-installed bloatware, freebees, trial versions and 3rd-party browsers/AV programs that are constantly backing up to Cloud.

With Event ID: 4,1, have a look at the Microsoft "Advanced troubleshooting for Event ID 41" guide link that I've provided for a solution, as the reason that you are getting the Event 41 is because the system has rebooted without cleanly shutting down first. This event indicates that some unexpected activity prevented Windows from shutting down correctly. Such a shutdown might be caused by an interruption in the power supply or by a Stop error. If feasible, Windows records any error codes as it shuts down.

You can't change the water-cooling water in your PO7-640 AIO cpu 96mm sealed water cooler, as it’s a sealed unit! To reduce the cpu temps, you need to change the cpu thermal paste with liquid metal paste for a gaming desktop, as its the most efficient paste to use, I suggest using the Thermal Grizzly Conductonaut Extreme liquid metal paste and follow their exact guide of how to apply this paste as if you don't then this liquid metal paste can cause permanent damage to your mainboard and PC, but this liquid metal paste can reduce up to 30C temps of your cpu, so its worth applying it. Good luck and hope this helps you out, and first rectify the ID 41 problem as that is what needs fixing.

You won't get a thermal shutdown until the CPU temp gets over 100C. Prior to that level there will be throttling to help cool things. The event ID 41 doesn't tell you anything other than the system turned itself off.

you have 2 choices…a new 240mm AIO or an air cooler.

i have a 13700K under my Noctua NH-U12A air cooler and in Cinebench r23 it hits 87C on the 30-minute run…..when gaming it sits at 66C using hwinfo64.

so right there you know that cooler is inadequate for the 12900K.

and i say that because the 13700K is more powerful and runs a lot warmer and I'm air cooling it no problem.

so, it's that simple, get a new nice 240mm AIO and it will fit up top or an air cooler.

Hello. Thank you for taking the time to help with my problem.

With +7 hours of uptime i meant that it is just running for +7 hours, but i am not gaming constantly in those +7 hours. Maybe about 3 of those hours are used to play games. The only tasks i have running while gaming is steam, the game i play and that's it. Well, it's not always only these 2 tasks, but for the sake of trying to isolate the issue, i tried only running a very few tasks and see if the issue still occurs. And unfortunately it didn't help. The issue also occurs when i am not gaming at all. I could be writing this very message and my PC could potentially shut down.

Here is a screenshot. This is how it usually looks. Just imagine there is a game running too.

Hello. Thank you for taking your time to help with my problem.

It's good to know that i cannot change the water in my water cooling system. I do not trust myself to perform that task, so i am glad i can exclude this for now. I will look into the troubleshooting link you provided, i haven't seen this one so far. It does look a little complicated for me to understand, so it might take a while until i fully figure out everything stated there and tried the solutions provided.

I am not quite sure how applying a new thermal paste could fix this problem, since my PC even shuts down when i am not playing any games at all. But usually it happens while playing a game. I will consider this once i have fixed the Event ID 41 problem.

Thank you again for helping me.

did you see what i said? replace that 120mm AIO with a 240mm AIO or an air cooler and all your problems will be solved most likely.

billsey

Since we haven't determined if the issue is heat related, changing the cooling system is an extreme step that might not make any difference. With temperatures running in the low 90s at max it's not shutting down due to thermal overrun.

Do you ever see a BSOD or does it just turn off? Are there any entries in Event Viewer just prior to the start of the reboot? Maybe wait five or ten minutes after a shutdown, start it up and look in Event Viewer, there will then be a noticeable gap in the events so you can try to see what was happening just prior to the crash. My guess is that it is a crash rather than thermal, but it would have to be a pretty hard crash to just shut off without a BSOD.

well bill you know more than me BUT we all know acer has an issue with cooling on EVERY desktop pc they make.

that 120mm rad is junk sorry to say but it's the truth and facts.

I'm air cooling a 13700K and having no issues at all with my Noctua NH-U12A.

so, it can only be a few things and i bet its insufficient cooling.

Hello. Yes, i have seen your suggestion. Something i didn't mention is that my cooler fans (don't know about the water cooler) never really go to 100% usage. I tried to manually adjust the fan speed once. And when i tried using 100% fan speed, my PC was very very loud. I never heard my PC getting so loud. In fact, it was so loud that i got a little scared something might break, so i never put them on 100% usage again. So assuming my fans usually never go to 100% usage since my PC never goes this loud, i think my PC never uses my fans at 100% capacity. So i kinda doubt it's a issue with my fans.

Something to also note: While adjusting my fan speed manually, i upped everything in the "curve" the program showed me by roughly 15%. Hoping that my BIOS (or whatever program is controlling my fan speeds) is just misjudging the needed fan usage in order to cool my PC properly. Unfortunately this did not help either. So i am back at letting my BIOS automatically controlling my fan speed.

Thank you for your input. If nothing else will help me fix my issue, i will consider making hardware changes in the future like you suggested.

well, there is a program called predator sense you have to download and use that to adjust the fans.

the BIOS is very limited and has a feature called smart fan.

and yes, that fan on the radiator is LOUD and a 120mm is not enough to cool a 12900K.

Hello. I just answered you before, but for some reason my message is not showing or didn't get through. So i am writing this again, hoping i'm not answering you twice.

No, i do not see a blue screen of death. My issue did not occur since i made this post. So it is kinda hard for me to go with all the solutions everyone provided.

This is what happens when the "crash" happens:
1. Both my monitors turn black.
2. After 5 seconds, the audio from whatever i was doing stops (could be a game, could be Youtube).
3. PC LEDS and fans still working while all this is going on.
4. My PC stays like this until i forcefully reboot it by pressing the power button for a long time. However, i never let my "run" in this state for longer than 1 minute, because i got afraid it could damage my system.
5. Very rarely when this "crash" happens, my PC did restart automatically. But usually i am the one rebooting it.

Also, this also happened when i was only using 1 monitor.

Thank you for providing help with my problem. Like i said, the issue didn't occur since i made this post. I was in the middle of taking apart my PC and cleaning it as best as i could when i was making the post. Although, there wasn't much dust to begin with. But, maybe the unplugging of various cables and plugging them back in did fix the issue for me. Thank you again for all the help.

Yes, i used another third party program to adjust the fan speed. It was called MSI Afterburner. There was a fan curve i could adjust to my liking and i just upped everything up. So instead of using 5% of my fans at 5 degree celsius, i changed it so it would use 20% instead. I don't remember the exact numbers anymore but that's roughly what i did. However, i am back to letting the fans being adjusted automatically, since it didn't resolve my issue.

Hello.

No, i am not getting a blue screen of death. Since i made this post, my PC didn't crash lately so it is kinda hard for me to go with all the solutions everyone provided.

When my PC crashes it happens like this:

Both monitors go black.
Im losing sound from whatever i was doing. (Could be gaming, could be just Youtube)
PC still runs, but i have never let it "run" longer than a minute because i was afraid it could damage my system. So what i usually do is, i press the power button for a long time to forcefully shut it down.
This happened rarely, but sometimes my PC will just automatically restart when that problem occurs.
PC leds and fans still seem to be working properly once this "crash" happens.

Thank you for your help. Like i said, the issue didn't happen since i made this post. I made this post in the midst of taking my PC apart and trying to clean it as best as i could. However, there really wasnt much dust to begin with. Still, maybe plugging various cables out and putting them back in might have fixed the issue.

ok so you have 2 monitors are they both plugged into the GPU or the MB iGPU?

billsey

OK, I'm still not thinking the issue is CPU temperatures. What happens when the CPU goes over the 100C limit is an immediate shutdown of everything, just as if you pulled the power cord out. Since you are seeing an event where the displays go away, followed by audio, and then nothing at all until you long press the power I'm guessing it's either a video driver crash, GPU card overheating or background application crashing. If it were a background app I'd expect it to as often as not give a blue screen. I'd start looking into GPU temperatures. If the GPU overheats it might get into a state where the GPU shuts off, blanking the monitors, followed by some sort of bus lockup which would freeze the rest of the system. When you had it open did you verify the GPU fans were running normally? Do you have a utility that tells you GPU temperatures? It might be worthwhile to reseat that card, though be aware of the latch at the back that needs to be released in order to pull it out.

Hi All,

I signed in for the first time because I can relate to this issue, I had the same thing with my Acer Orion 7000 PO7-640, the issue was happening randomly when I was just going through normal use and then more often when gaming,

after a month or so I discovered that this PC was still running with the original Bios R01-A1, you can find what Bios you're on in system info

I updated to R01-A4 first which resolved my issue and then to the latest above, you can get the drivers from here:

https://www.acer.com/us-en/support/drivers-and-manuals

the installer package runs the Computer restarts and will need to load up new bios, this is the part people usually hold their breath for as if by chance the power goes out and it doesn't load up it can "Brick" your computer, but this did resolve my issue and for others who bought the same desktop from the same shop, something to check out as most of us will usually forget about updating Bios, and the latest Bios comes with system optimization and I know my beast is now purring instead of choking,

I hope this helps :)

P.S. is there any specific 240 AIO that will connect on the existing 140 AIO Fan-pump and fan PWM connectors, I'm looking for a tried and tested with 240 AIO upgrade that works with Predator Sense?

thanks.
