    BSOD While CPU Under Load

    Hi All,

    I've been bashing my head against the wall trying to figure out this intermittent BSOD issue I have. It seems to mostly happening while the CPU is under intense load, but isn't really consistent. For example I played Destiny 2 pretty heavily for a few days without issue at more or less max settings, but trying to run a video render or even just playing WoW Classic while having Amazon Prime Video open on the other screen causing the system to crash out.

    Typical BSOD analytical tools like WhoCrashed and BlueScreen viewer aren't really pointing to anything other than ntoskrnl.exe and ntkrnlmp.exe as the culprits.

    I've tried running MemTest86+, which returned no errors after 11 passes, Intel's Processor Diagnostic utility, which passed all tests without issue, and FurMark, which also passed with no issue.

    Prime95 however will not run a single test without a failure or system crash. I've run Smallest, Small, Large and Blend tests and they all either BSOD or crash the application itself.

    I'm thinking I might have a bad CPU, but really would like a fresh set of eyes on this before having to put the money down to replace it.

    First thing I noticed is you have a problem with NVIDIA High Definition Audio HDAUDIO\FUNC_01&VEN_10DE&DEV_0082&SUBSYS_38426390&REV_1001\5&BB0E20&0&0001 32.
    Try updating the driver, see if that helps.

    The 9/9 dump indicates a problem with CorsairLink4.exe. This is a program for overclocking ram or something like that, right? Uninstall it, set all values to default so there are no overclock or over/under volt settings and see how things run.

    If that doesn't help then give Driver Verifier a try:

    Run Driver Verifier

    Enable and Disable Driver Verifier in Windows 10

    Following the instructions in the above link will check for problems in all non-Microsoft drivers.

    What we're looking for is a verifier generated BSOD with a mini dump that will tell us what driver caused it. If you get a BSOD, rerun the V2 log collector as soon as possible and upload the resulting zip file. Also see if there is a new C:\Windows \MEMORY.DMP file. If there is, copy it to another location then zip it an upload to a file sharing site like OneDrive and post a link to it here.

    To check if verifier is active, open a Command Prompt and enter:

    verifier /querysettings

    If not active it will respond with

    Verifier Flags: 0x00000000

    Standard Flags:

    [ ] 0x00000001 Special pool.
    [ ] 0x00000002 Force IRQL checking.

    CorsairLink.exe is just a program for managing the H115i CPU cooler. I don't ever mess around with overclocking or adjusting memory voltage so all of that should be the default already. I'll try uninstalling and see if that helps along with updating that nvidia driver and see if that helps.

    - - - Updated - - -

    After updating NVIDIA drivers and uninstalling the Corsair software as suggested, Prime95 did run for a significantly longer time than previously, however in the end still caused the system to crash.

    Will next try driver verifier and use PC as normal.

    Here are the logs from the most recent crash:

    There may be another crash in there from tonight, I had removed my processor to get the warranty information from it, cleaned it up a bit and applied new thermal paste, and ran Prime95 to see if that helped before reading your initial reply, but no dice there.

    Also, please read the documentation that comes with Prime95

    So I've run Driver Verifier for 2 days now with regular usage and no BSOD issues.

    Testing with Prime95 afterwards is still producing system crashes. I've tried to follow the instructions linked by jdc1, but I'm honestly having a hard time following what the author is saying about pretty much anything.

    Here's what I've been able to document at least. I ran each of the tests about 3 times each.

    Running a Blend test BSOD's after about 6 and a half minutes.
    Running Large FFT produces an error in the application which stops the test, also after about 6 and a half minutes.
    Running Small FFT crashes the Prime95 application after about 30 seconds.

    Here are the V2 logs collected after the Prime95 tests and crashes:

    If I'm understanding that link correctly, that seems to point to a CPU issue?

    There are many indications, but I will ask. What temperature does the CPU reach during testing when a crash occurs?

    Had another crash while playing a game and watching a video in the other screen, after doing so for most of today.

    Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

    Didn't catch the temperature for that crash, but ran the Prime95 tests again afterwards and experienced another crash running the Blended test. CPU temp hovered around 70 degrees for both the blended and Large FFT, peaked at 90 degrees for small FFT before the application crashed.

    I swapped out the memory for the system after the initial crash today with brand new sticks and had no change in behavior so I'm leaning to believe that the RAM is not the issue.

    Have you checked if the thermal paste has dried? Have you cleaned the computer of dust (in particular the CPU and its cooling)?

    Instructions for Driver Verifier get sorta complicated due to the many options available.
    In short, the intent is to stress drivers. If a driver is faulty, the system is supposed to give a BSOD (one that is Driver Verifier enabled). And, hopefully, it'll reveal which driver was faulty.
    But, there's lot's of reasons for it not happening - so don't sweat it.

    Have you read this post about Prime95: Prime95
    Scroll down to the DISCUSSION section and start reading there.

    Also try the OCCT tests mentioned there (it's free from here: OCBASE / OCCT )

    In short, Prime 95 tests:
    - RAM
    - CPU cache
    - memory controller (built into the CPU)

    So, it's either your RAM or your CPU (other faults are less likely, but still possible - such as a motherboard problem).
    Can you borrow some RAM to test with? You have G-Skill RAM - which usually comes with a lifetime warranty.
    Maybe contact G-Skill for replacements?
    As for the CPU - do you have another compatible CPU that you can test with?

    You may be able to purchase replacement RAM and/or CPU from a shop that will let you return it (for your money back) if it's not needed. Check BEFORE purchasing though!

    Good luck!
