WHEA_UNCORRECTABLE_ERROR BSOD In New System Build

I just completed my first build and am getting frequent WHEA_UNCORRECTABLE_ERROR crashes. They seem to only occur when trying to load/install things having to do with the graphics or other updates. Windows Update reliably crashes, as does trying to launch certain games from Steam (Torchlight II). If I let the CPU sit idle, browse the web, etc. it doesn't cause any problems.

I'm using the default BIOS settings. I've updated all my drivers and the only odd thing is that while Device Manager recognizes my graphics card and says I have the latest drivers, the bundled software from nvidia doesn't fine "compatible hardware". In any event, given that I can complete Windows Update, I'm stuck on the Microsoft troubleshooting steps.

Obviously I'm really hoping that it's a driver issue and not something with hardware. I'm relatively new to this so not sure how to proceed. Any advice is very much appreciated.

Motherboard: ASUS Z87-Plus
CPU: Intel Core i5-4670k
Memory: Corsair Vengeance DDR3 1600MHz (8GBx2)
Storage: Samsung 840 EVO 250GB

  1. -if you put a copy of the memory dump on the cloud with public access (skydrive works) i will look at it with a windows debugger and can tell you what the OS is complaining about.

    - sometimes on a new build you just need to update the BIOS, to get microcode updates to the cpu, better memory timings, better memory and cpu voltage settings. Also, on a new build you will want to get the various chipset driver updates for your hardware. You don't want to depend on the generic files that microsoft puts in the OS.

    Thanks, johnbl. Here's a link to the memory.dmp file on my SkyDrive: https://skydrive.live.com/redir?resid=37C2288459A2F877%21421

    Processor Version Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz
    Processor Voltage 8ch - 1.2V


    CPU generated a fatal error when it attempted to write to CPU cache memory and failed.
    Error on Proc 1 Bank 1

    -would recommend update BIOS to current version to pick up any cpu microcode fixes, and BIOS tuning changes.
    -would recommend picking up updated intel chipset drivers directly from intel download site.

    -if the above is up to date, i would check the processor voltage selection in BIOS

    the win32k memory image is corrupt with 1035 errors in the binary.

    recommend running the command
    cmd.exe as a admin
    then scf.exe /scannow to attempt a repair of the file.
    if no errors are reported, you must find what corrupted the file as it was loaded into memory.

    if the error is not on disk, I would update your intel disk management drivers to the most current version from intel (iastora.sys,...)

  4. I updated the BIOS to the latest version and was then able to successfully complete the native Windows update. I tried to update the intel chipset drivers from the site but their utility could not locate anything to update, so I'm at a bit of a loss there.

    The good news is that I was able to complete the update I couldn't complete previously and load a game that was a reliable source of the crash.

    I also downloaded Driver Booster, the well reviewed utility from CNET. It identified a few out of date drivers, including for the video card, which it updated. So, I'll keep trying a few other programs, but am cautiously optimistic for now.

    Thanks again.
  5. be sure to run the system file checker
    sfc.exe /scannow to confirm that your OS files are not corrupt on your disk drive
    one file was corrupt in your memory image, this can indicate a bad spot in your memory or a bug in a driver or hardware. Windows will load the file in a different memory location on each boot to prevent hacking or virus infection. Because of this, you could still have the same problem and not detect it until you have rebooted many times. (critical kernel structure has to be in the effected memory area before the OS will bugcheck)

    I ran the sfc and it found no integrity violations.

    Your next recommended step was to update the intel disk management drivers. I ran the online utility and it cannot detect the products "The device is unknown or not supported". I can do it manually, but I'm not quite sure what I'm looking for.
  7. try the manual install of Intel® Rapid Storage Technology dirver

    https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=2101&DwnldID=23496&keyword=%22iaStor.sys%22&lang=eng

    using the .exe version.

    cool that your image on disk is ok, not good that it was corrupt in memory, the file is a common attack vector for malware. you might want to run malwarebytes and do a scan just in case.

  8. I'm clean according to Malwarebytes, so that's good. I ran the Intel .exe and it seems to be a utility -- not sure that it installed anything, but in the Current Status window is says that my system is functionally normally and configured to enable advanced SATA features.
