Computer Shutting Off At Random Times

Hello. My computer seems to be shutting off at random times, and I really don't know where start searching for problems. I'd say it happens about once or twice every 2 days. It powers back on, and the last time it happened (today), my screen was stuck on a blinking underscore with a black screen. That was the first time it has happened like that. The case power button would not turn the computer off so I had to flick the actual power supply switch off and on to reboot. Now it had started up properly. I am willing to follow any directions in order to help me get to the bottom of this issue.

I have been using this computer for about 13 months and this has only been happening starting 2 weeks ago. All of the fans appear to be spinning, and nothing seems urgently wrong physically.

  1. Try running your memory at 2133 MHz for a few days and see if the problem clears up. Any speed over 2133MHz is an overclock which may make your computer unstable.

    Other possible problems:

    1. Check your drivers in "Device Manager". Look for yellow warning signs.
    2. Computer virus or malware. Run antivirus scan.
    3. Western Digital HDD is starting to fail. Install Hard Disk Sentinel software to test your drive for bad sectors.
    4. You PSU is starting to fail. That's a difficult thing to test.

    1. Nothing stands out under all categories
    2. A few were found, all 12 were appdata for google chrome, not sure if they could cause my computer to shut down.
    3. Used that program, both drives are perfect according to it.

    How exactly do I limit my memory usage? Could you link me to a guide? All my google searches lead me to limiting specific programs and other non-local stuff.

    Are you asking how to lower the ram clock speed?

    Yes
    Edit:
    Although, I have had this computer for over a year and haven't had this issue until recently so I'm going to assume that wouldn't be the issue. However a PSU getting old and starting to fail seems possible for me.

    One thing I have not done in the ~13 months of owning this computer is replacing the thermal paste on the cpu cooler. Could this be the problem? I tried to download a program recently to see my CPU temperature but I simply don't know how to read the program. Is it even possible to monitor the temperature? lol

    I don't see temperatures listed anywhere in CPU-Z. I prefer to use "Speccy" which shows the temperatures of all your components.

    Okay, using that program now. Temperatures all around seem okay and float at 25C-40C except for the GPU which I believe is supposed to float at ~50C.

    I don't know if this would be useful, but are the Windows events any reliable? I always see "Event ID: 41 Kernel-Power", Does this simply mean the system shut off for X reason, therefore the power was turned off, or is it directly stating that the power unexpectedly turned off (due to the PSU cutting out).

    A memory dump file [or .dmp file] can be useful to look at after a crash. It should be able to tell you what caused the crash.

  8. Here's an update:

    I had only just turned on my computer 10 minutes prior to it crashing (at 8:02 am). The first error that appears is the "Critical" one. Followed by all those other ones. I'm not sure if it's random or actually in proper order, but could this mean something is wrong with the power supply?



    Also, I've noticed that a lot of the time before crashes, this error appears. I've searched it up and it is related to my default motherboard soundcard. I did not state this before because I did not think it was relevant, but I do have a sound card. I installed back in January though. I feel like it might not be relevant because this ATKEX error only appears before half of the crash events, and most of the time hours before. The only reason I felt like it was connected was because I was only 10 minutes into using my PC, opened up YouTube, opened up a new tab for a song and within 3 seconds of listening, the PC crashed.



    At this point I'm thinking I might just buy a new PSU and see if my PC ever crashes for a while. I'd hate for something horrible to happen to my hard drive or something due to an unexpected crash.

    By any chance are there any programs that monitor all your hardware temperatures and also give alerts when one of the components is about to reach maximum temperature?

    If you have even a slight suspicion your problems may be caused by your add-on sound card, just remove it for a few days to see if the problems go away. You can also look at the sound card in Device Manager to see if it has the proper drivers installed.

  10. I guess I shouldn't have even said that considering I get the same error 4 times upon startup. I have noticed that every time I crash, it happens while in Chrome. It could be coincidence, or could not be. I do spend a lot of my PC time in Chrome. I have never crashed while playing a game though.

    I'm going to buy a new PSU and in the meantime try to find a new temperature monitor program that has alerts.

  11. The ATKEX error does not relate to the PSU, it is the software problem, something related to the audio driver(s) like other member said.

    Try run the SFC.exe https://support.microsoft.com/en-us/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system to fix the software problem.

    If it does not work, then try uninstall the audio driver, then use ccleaner to clean system registry files, then reinstall the driver.

    Here are some links about the Event ID 41 Kernel-Power error, see if they help.

  13. Windows Kernel event ID 41 error "The system has rebooted without cleanly shutting down first" in Windows. https://support.microsoft.com/en-us/help/2028504/windows-kernel-event-id-41-error-the-system-has-rebooted-without-clean

    The PC shutting down related to ATKEX error, but no PSU.

  14. I don't think the ATKEX error is related. It happens upon start up 4 times simultaneously. Guessing it's some interference between my sound card and the default motherboard card (ATKEX), which I have had since January. It appears my first crash was October 13 and these 4-time ATKEX errors started happening upon startup since August.

    I did that system chceck and:
    "Verification 100% complete.

    Windows Resource Protection did not find any integrity violations."

    How is kernel power not related to PSU? Those links provided both suggest that it is a possibility.

    Edit: Note that I never said the ATKEX was the reason for the crash, but simply something that I've been getting. So this should NOT eliminate the possibility of a faulty PSU giving out.

  16. From your error logs, you can see the application error and deviceset Ma.. warning, that means either the sound card driver or MB audio driver, even the gtx1070 audio driver too.

    Try uninstall the MB audio driver, just use the sound card and GPU audio driver.

    Kernel ID 41 does related to PSU sometime, like the PSU can not handle the GPU, but from the error log, that error does not show up. But your PSU EVGA SuperNOVA 650 G1 should be able to power the gtx1070, but don't hurt to check it out, go into the BIOS, in hardware monitor or pc health monitor section, check out the +3.3V, +5V, and +12V. You want to see those voltages are within +/- 5%, eg: +3.3V, it should be like +3.1 V to +3.4 V. If it does, the PSU is good, otherwise you need the new PSU.

    Okay I'll just disable it (same thing, no?).

    Restarted after disabling, not getting the error anymore. Now to see if I ever crash again.

  18. Just crashed again while playing a game (but I tabbed out to do something on Chrome). Definitely not the ATKEX thing.

    By any chance does anyone know a way to make an mp3/wav play through .exe? I have this temperature monitor that is able to execute an .exe upon detecting overheating.

    Other than that, I don't know what to say. I have changed my room temperature from 20C to 23C about a month ago, which is during the time these crashes have started happening. Also my tower is on top of a rug. Perhaps I could elevate it if that is the issue.

  19. I disabled hardware acceleration on google chrome while continuing my habits, and everything seems fine so far. If I can go a week without crashing then it was definitely that.

  20. Unfortunately it's been happening again. Installed SpeedFan to see if it's really a temperature issue and apparently AUXTIN1 is hotter than usual. If I'm not mistaken that's the PSU?

    AUXTIN1 would not be your PSU. You should just ignore that number, the same way you ignore -128C. 50C is not very high in any case, i believe if it were one degree lower it would not show any warning at all.

    If you think your PSU might be running hot, just hold your hand behind the exhaust fan to feel how hot the outgoing air is. If it's not too hot for your hand it's not a problem.

  22. At this point I'm certain that it has to be the CPU or GPU. I often hear an intense whirring of the fans before it happens. Also I can feel a bit of warmth on the side of the case when it happens, but only for a couple seconds before it dissipates.

    Is there any way to check which of the two it could be? Both of their fans are functioning properly.
