    Random BSODs, 100% Utilization, and Driver Issues


    Hello everyone. I've had a great experience with this site. The How-Tos and Tutorials have been more than helpful numerous times I've had to diagnose and fix system issues. However, this time, things seem to have got out of hand and are beyond my area of expertise. Instead of breaking something, I have decided it would be best to have more experienced users take a look. I have attached the appropriate information requested, along with the following (which includes memory timings, CPU-Z reports, etc..: Lots of system info via Imgur
    Note I am NOT overclocked. Also included in the attachment is an excerpt from a string dump (produced with process explorer) of ntoskernel.exe that is riddled with errors.

    Symptoms:
    • Seemingly Random BSODs (rare)
    • BSODs able to be reproduced: Format SD card using SDFormatter (near 100% chance)
    • Random intense CPU utilization and subsequent freezes and lock-ups


    Notes:
    • Appears to be driver related.
    • The system never hangs and requires a restart, if I wait it will resolve. Lag spikes are typically 1-2s, a few seconds max.
    • Hamachi Driver reports an error but Hamachi seems to function fine.
    • If it means anything, I have two stuck core temp sensors (DTS) at 56C. I am working on diagnosing and repairing this in a separate thread elsewhere.
    • Process Explorer shows "TID 64, CPU 48.65, CSwitch Delta 458, Start Address 'ntoskrnl.exe!KeAcquireInStackQueuedSpinLockAtDpcLevel+0x1e0'" as the thread which uses large amounts of resources.


    Thanks in advance and I am more than willing to provide any more information if necessary.

    A memory test is called for here.
    http://www.geekstogo.com/forum/topic...ing-memtest86/
    If you pass this test, it is probably a driver, fastfact.sys.
    Right now I think memory is the most likely candidate.

    A few questions.
    I ran a MemTest much earlier in the year overnight and everything checked out. How long do you recommend I run it for this time? Any specific program options or should defaults be fine? Should I test a single module at a time or both? Would it be best to modify any BIOS settings such as loading Optimized Defaults or Fail Safe Defaults prior to the testing or is my current setup fine?

    Run it for at least 8 passes.
    If fails take a good stick and test each slot for 8 passes
    If passes, take a good stick and test each slot for 4 passes
    Thats all you need to do.

    While I'm sure it isn't 100% guaranteed, it looks like my memory is fine. 12 Passes Dual Channel Interleaved. 9 Pass single module #1. 5 Pass Single Module #2 (both were tested in first slot). Will provide screen shots but I don't think it matters all that much since it's passed. Let it run for a while since I had loads of other tasks to tend to today, anyway.

    If your RAM check out ok and you are sure that you did the test correctly:
    Update the driver that was mentioned. If you still have problems, I feel that the BSOD is still memory related.
    YOu have high usage:
    Run a full anti virus scan
    Download and run malwarebytes. Make a full scan and be sure that it is upadated.
    When you have the high usage, bring up task manager (process) and see what is using the resources.

    In response to the above I should be virus & malware free as I have Microsoft Security Essentials and perform regular scans. Before posting here I ran both Kaspersky AV 10 Rescue Disk (updated), MB Anti-Malware, Super Antispyware, and BitDefender Rescue Disk (updated) just to be sure.

    I have brought up Process Explorer and as I stated in the original post, it is PID 4 System: "TID 64, CPU 48.65, CSwitch Delta 458, Start Address 'ntoskrnl.exe!KeAcquireInStackQueuedSpinLockAtDpcLevel+0x1e0'" as the thread which uses large amounts of resources. Image attached.

    As for the fastfat.sys driver, which site(s) do you recommend me to find the most current stable version for Windows 7 Ultimate x64 SP1? A quick search for it results in multitudes of sites with versions for multiple OS, some riddled with advertising and asking for registration, etc.

    Thanks for your assistance, this issue has been frustrating me for quite some time and at least it appears we're making headway.

    Would the 32 bit version fastfat.sys work with a 64 bit computer? I have a 32 Bit Windows 7 Enterprise running SP1 I could copy from but not another SP1 64 bit. The download sites online don't seem to list versions and someone suggested running Reimage Windows Repair but it looked sketchy.

    Any word on the process explorer report?

    Lets start with the easy way first.
    run 3 times if errors are found and are not repaired.
    SFC /SCANNOW Command - System File Checker
    Dont know of a site to get fastfat. Its a MS driver. Since the driver is part of the OS there may be other ways to get it. Try the above first.
