    Random NON-BSOD crashes, Event ID 41: Kernel-Power


    Please do not ask me for dump files or anything related to BSODs: My crashes are not related to BSODs. I HAVE NOT GOTTEN ANY BSODs AND THUS DO NOT HAVE ANY DUMP FILES.

    For about the past month and a half, I've been getting random crashes in Windows 7. My computer suddenly turns off and reboots itself. Just a black screen. Sometimes I don't get a crash for five days, sometimes I get one twice in the same day.

    My copy of Windows 7 wasn't genuine. I did a completely clean install of a genuine copy of Windows 8.1 one week ago, just to rule out problems on the OS level. I just got a random restart an hour ago. I only brought over media files from Win7, so I'd say my problem must be hardware related, or something to do with my power socket.

    Thoughts? Unfortunately, I can't change sockets easily, as I would have to move my computer into another room for possibly weeks just to see if the problem reoccurred (it's so rare).

    The event viewer shows that these crashes coincide with Event ID 41: Kernel-Power. The event data is always blank as follows:

    BugcheckCode 0

    BugcheckParameter1 0x0

    BugcheckParameter2 0x0

    BugcheckParameter3 0x0

    BugcheckParameter4 0x0

    SleepInProgress false

    PowerButtonTimestamp 0

    My monitors do not turn off when the computer self-reboots and they are connected to the same surge protector as the computer. Does that pretty much rule out a socket problem?

    My computer specs (nothing is overclocked):

    i5 3570k @ base clock
    Gigabyte Windforce 3X GTX 670 graphics card
    Dell U2312HM (main monitor)
    Dell P2214H (2nd monitor)
    CM Storm "Spawn" mouse
    Corsair K70 mechanical keyboard
    Corsair TX750M PSU
    16GB Corsair Vengeance LP RAM
    MSI Z77MA-G45 mATX motherboard

    Seagate Barracuda ST2000DM001 2TB HDD
    OCZ 120GB Solid 3 SSD

    Things I've tried:

    1. Ruled out overheating: my computer is very well cooled. Prime95 can't push any of my CPU's cores past 50C. My CPU runs @ about 35C during heavy gaming and my GPU doesn't seem to get past 40C.
    2. Run Prime95 for about 14 hours with no errors.
    3. Run Memtest86 to rule out faulty memory. I only did one pass, so I'm guessing I should do more?
    4. Unchecked the "automatically restart" option in advanced system properties. It hasn't had any effect.
    5. Uninstalled my GPU drivers and updated to the latest ones.
    6. Tried to rule out a faulty PSU to no avail. Hardware monitor programs give me crazy voltage readings (8V on my +12V), but voltages seem normal in the BIOS. Should I buy a digital multimeter to test voltages under full load?

    Any and all help would be very much appreciated. This problem seems very hard to solve and I really need outside help at this stage. If you need any more information, dont hesitate to ask.

    Thanks for reading,

    Swift

    Hello Swift,

    Seems more of a power statement than a bsod issue of some form.

    Your system also has the capability of shutting down in the event of some form of MAJOR hardware fault.

    I have this issue several times with servers in the past, most of the it turned out be a fault PSU.

    Have you tried running LinX Stress Tester? with max settings all ram included?

    Cheers

    Just a quick update,

    I can 100% tell you that this "8V on my +12V" is not normal.

    That rail should always be at 12V regardless of load.

    Cheers

    That's why it says "non BSOD crashes" in the title

    I realise that 8V on the +12V rail is NOT normal. But as I said above, in the BIOS voltages are normal. I did research and I'm not the only one to get crazy readings from hardware monitors. I'm not saying it's not the PSU, but if my BIOS shows normal readings, why trust a hardware monitor that gives me crazy readings when my computer is at idle? I don't know if my computer would even function if my +12V rail were at 8V.

    I'll try Linx, cheers.

    Hey,

    Okay well another potential issue to give you is that when the system loads into Windows it generally uses a lot more power than when in the BIOS.

    The BIOS is designed this way to specifically prevent any issues occurring, for example your GPU, CPU, RAM etc... are all at full swing when it goes into the operating system.

    This draws more from your PSU and your RAIL of which here is why your having issues in an operating system rather than the BIOS.

    What PSU do you have?

    Cheers

    Also do you have an SLI on those 670 GPU.

    Is there just 1 card or 2 etc...

    Everything there is exactly what I have. No SLI. My PSU is a Corsair TX750M.

    I see, but does that match up with the sporadicness of my crashes? I've gone weeks without a crash, and I use my computer intensively every day. I've gotten crashes when idle, too. Leave the room and come back to find myself back on the welcome screen.

    Yes,

    I mean i had an EVGA Supernova power supply with the exact same symptoms.

    That power supply was 1500WATT it ran great for over a year then the sudden't power off would happen.

    Eventually it just died.

    I suppose here what you have to look at is the following.

    You've been driving your power supply ( of which i don't know the specs, if you could post the specs i would know more ) every power supply has it's limits and generally once it's been pushed and pushed the voltage issue you are describing comes into play.

    If your system has any form of incorrect voltage whether it's IDLE or in USE, generally and instant power off is performed to prevent hardware damage as unregulated voltages can cause serious damage to your components.

    I would take a guess here, i recon your system turns off more when it's IDLE than it does under load? Would this be correct?

    Cheers

    Event ID 41 crashes are Windows way of saying it doesn't know why it crashed.
    This can be due to hardware problems (to include overheating), to BSOD problems, or even to just shutting the computer off by holding down the power button.

    The reports that you submitted don't include much information on the crashes.
    Please do the following:
    - open Event Viewer (run eventvwr.msc from the "Run" dialog))
    - expand the Custom Views category (left click on the > next to the words "Custom Views")
    - right click on Administrative Events
    - select "Save all Events in Custom View as..."
    - save the file as Admin.evtx
    - zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
    - upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

    While waiting for a reply, please monitor your temps with this free utility: HWMonitor CPUID - System & hardware benchmark, monitoring, reporting
