    PC froze, had to turn off PSU, seems fine now - cause for concern?


    My PC is a few years old and is doing fine (had some issues related to broken RAM partially corrupting the OS but that's fixed now). However, I just had a hopefully one-off incident occur and am not sure if I should take any futher action about it.

    Bullet points for succintness:

    • Sleep, hybrid sleep, and hibernate are all disabled. PC is set to turn off the monitors after 10 minutes of inactivity, which is what I assumed happened until it didn't respond.


    • The PC had been on overnight and had the monitors sleeping for that whole time. It was behaving normally until this occured after ~30min of use after I and the PC woke up. It had been on for about 24 hours in total.


    • Applications running at the time: just Firefox and Sticky Notes, plus my normal background apps (GHub, Razer Synapse, etc) Edit: also the W10 clock, I was running the stopwatch.


    • During the period it was unresponsive, the CPU error light on the motherboard turned on. It's a B450 Tomahawk Max which has apparently had issues with the CPU light erroneously coming on. It's off now after a reboot.


    • Did not respond to peripherials being moved/pressed. Did not respond to hard shut down via power button. I had to turn off the PSU and unplug it from my UPS for a few minutes.


    • Restarted and everything seems fine.
    • W10 (up to date via a recent repair install), Ryzen 3700X using Ryzen Power Plan Balanced.
    • Never had any other issue like this. Usually turns off the monitors and mouse/kbm/etc and wakes up instantly when prompted.


    ... Should I be concerned? Did the CPU have a brain fart this one time? The PC seems to be behaving normally, there are no errors in Event Viewer that I've seen. No data loss, no weird behaviour. It was like it locked up or froze from an application, except it was while the monitor was off and did not respond to the power button.

    There've been no other CPU-related issues. There was an incident yesterday where I accidentally hit 100% RAM consumption with Blender (I subdivided too hard lol) but that's just the RAM.

    Does Reliability History have any entries and/or flags covering the freeze?

    If there is, as I'd expect, a gap in Event logs then the last few entries before the gap might reveal something useful even if they are not 'error' events.
    Event viewer,
    Custom views,
    Administrative events [which means, translated into English, All events].

    If those the last few entries don't point to anything in particular I'd start monitoring temperatures.


    Best of luck,

    I was concerned something was happening with the CPU but hadn't considered it might've overheated. It was at near idle in a 15-20C room and the fans have only a light layer of dust (cleaned when I swapped my RAM a few weeks ago), but I haven't refreshed the paste (NT-H1) since I built it. Definitely something for me to keep in mind.

    Nothing about the freeze itself, just the standard error about Windows not shutting down properly (from when I had to switch off the PSU to restart).



    Side note:
    ASUS Com Service (AtkexComSvc.exe) reports crashes 2-5 times a week -- possibly with each boot as I've been leaving it on for a few days at a time -- without ever having an appreciable effect on the rest of the system, so I've left it alone. It was installed with iCue, which according to what I read, uses it to control motherboard-controlled lighting.

    Over the last few hours I've been looking into it and have found some discussions (ex1, ex2, ex3) about ACS possibly causing hard crashes like the one in question, and disabling it seeming to not affect anything else. Maybe it'd be a good idea to disable it just to eliminate the possibility it caused this hard freeze? It's probably coincidental given the service starts and then stops at boot semi regularly, though.

    While writing this post I went and downloaded Ryzen Master; ambient's about the same as mentioned at the top of this post, 15-20C, and my CPU is currently at 38-41 degrees. I'll start keeping an eye on it to see if it jumps up above e.g 85, especially since both you and Hearsepilot mentioned temps.
    The only recent hardware change is the new RAM, which apparently runs 10 degrees cooler than my previous RAM (A-XMP is also off).

    Event Viewer has suspiciously nothing for the seven hours before the crash happened. Usually I'd expect some more DeviceSetupManager events (they're all 200, 201, 202). The PC was idle from around 5pm as I left it on when I went to bed, but seven hours of no events?

    - Error: 1101, EventLog: Audit events have been dropped by the transport. 0
    - Critical: Event 41, Kernal-Power: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
    - Error: Event 6008, EventLog: The previous system shutdown at 12:47am was unexpected.

    The last error before the crash, buried below a couple dozen more of those warnings, was just from me crashing Blender (3d modelling application) through user error at 2pm.

    Windows 10 is just like any other machine and have it's limit of how long it could stay on, and performance lag will show over a couple of days.

    1. Check what is running in the background
    2. Cut of telemetry and anything you feel that is talking that should not be talking. In fact go find "Shut up Windows 10" ( program with a blow-horn for icon ) and run that to see how many things "you feel" should be shut off
    3. About "file indexing". I would cut that off but that is up to you.
    4. Some browsers ( like Firefox ) reloads pages and does constant writing. This can ware-down a hard-disk-drive, and cause a SSD to die early.
    5. Using crystal Disk mark ( whatever hard drive grade application is a must ). Just let it to a check of your primary drive.
    6. If the ASUS ( whatever brand program ) is not a high level need, then disable the process from running.
    7. Unless you need Windows 10 to be online consider that if you have Automatic updating enabled all sorts of stuff could happen.
    8. Windows Security is another problem maker and that is your decision to turn on or off.
    9. Also a good chance maybe the GPU or another device turned off. Disabling and enabling it might solve the problem temporary.
    10. resmon.msc could check your memory usage and RAMMAP ( third party tool ) could be used to clear some RAM ( again your choice )

    .................................................................................................... .......................................

    I would also run a 3rd party virus tool, and have it sweep for any bugs the computer has or had, or possibly anything that looks odd in your services, task scheduler, or startup ( via taskbar or whatever ). Some virus tools will leave a log you should be able to see.

    .................................................................................................... .......................

    If it is a non SSD it is possible the hard-drive did get over-heated, but even SSD get over-heated. Crystal Disck mark can check this.

    .........................................................

    As long as the heat levels are not in the 100 area you should be okay. Beyond that the primary ( ideal ) heat area is 65.

    Slow downs for me occurs when the GPU disconnects or even CPU switches to a lesser mode. Also remember you can use Taskmanger to assign applications/programs specific processors. Rather then having "Processor number 1" doing most of the calculations. This way processing power is spread across all processors and will actually cause a drop in temperature and free up processes.

    In Reliability History,left click on ---Asus Com Service --- then Right click on it.This should present a report giving information as to why it stopped working
    In any case an uninstall/reinstall of the product can be beneficial.
