    Frequent BSOD, ntoskrnl.exe, ntkrnlmp.exe


    Hello,

    since some time I got occasionally BSOD and since this Sunday very frequent.

    Background:
    Last Sunday I start troubleshoot long time pending issue with my USB 3.0 controller (VIA VL800 chipset) that I had since its installation in Dec 2011 (error Code 10: The device cannot start). I found and installed new driver from VIA (V1.90A_WHQL). There was no success, still the same error.
    I also changed SATA mode for my SSD disks from IDE to AHCI, using microsoft procedure and tool from Error message occurs after you change the SATA mode of the boot drive. Since this change USB controller started to work.
    Then I wanted to make backup via Windows embedded Backup & Restore tool and got few seconds after starting backup BSOD. Since then many BSODs (looked like when there was some operation with extenal USB disk), some times not possible to boot, because order of bootable disk has been changed in BIOS (I do not understand how it is possible w/o entering into BIOS)
    So I removed USB controller completely from PC, including deinstallation of driver (controller was in PC ~11 months), I reverted back AHCI to IDE in BIOS (but did not change back value for HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\msahci to 3), but problems with frequent BSOD are still there...
    I googled and read many forums/advices and finally arrived here.

    Can you pls help and give me advice what to do (I want avoid new Win7 install if possible)

    Welcome

    Almost all the BSOD-s were caused by Acronis True Image Snapshot Manager driver also included in Seagate DiscWizard - snapman.sys

    Uninstall to test

    Newer files will be checked

    Code:
    *** WARNING: Unable to verify timestamp for snapman.sys
    *** ERROR: Module load completed but symbols could not be loaded for snapman.sys

    *                                                                             *

    Probably caused by : snapman.sys ( snapman+1ca5f )

    It seems as if your antivirus/firewall program is also causing issues:
    Code:
    fffff880`0331aa28  fffff880`044ae300Unable to load image \SystemRoot\system32\DRIVERS\Epfwndis.sys, Win32 error 0n2
    *** WARNING: Unable to verify timestamp for Epfwndis.sys
    *** ERROR: Module load completed but symbols could not be loaded for Epfwndis.sys
     Epfwndis+0x1300
    ......
    fffff880`0331a5c8  fffff880`038810c0Unable to load image \SystemRoot\system32\DRIVERS\epfwwfp.sys, Win32 error 0n2
    *** WARNING: Unable to verify timestamp for epfwwfp.sys
    *** ERROR: Module load completed but symbols could not be loaded for epfwwfp.sys
     epfwwfp+0x60c0
    Please uninstall with its removal tool.

    Make scans with the following:

    -Kaspersky TDSSKiller

    *Update your network drivers.
    Recommended antivirus program for Windows 7 based on stability compared to others:-


    Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

    Run a full scan with both (separately) once downloaded, installed and updated.

    Run the System File Checker that scans the of all protected Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:

    • Click on the
    • Type CMD on Search
    • Left click and Run as Administrator
    • Type SFC /scannow

    Full tutorial here:

    Run Disk Check on your hard disk for file system errors and bad sectors on it:

    Free up the start-up, nothing except the antivirus is usually needed.

    Hello koolkat77,
    I did some cleaning (partially as you suggested and partially other actions taken), attaching new logs.
    Can you please have a look if you now see still some critical issues that might cause problems?

    I personally still see some issue with : \SystemRoot\SysWow64\Drivers\ANGELNT.SYS has been blocked from loading due to incompatibility with this system. Please contact your software vendor for a compatible version of the driver.
    Wanted to deinstall but I have no idea to what SW/app this driver belongs...

    Note: Since last time no BSOD :)

    Check for an update on the BIOS version:
    Code:
    BIOS Version/Date	American Megatrends Inc. 2203, 08.07.2009
    Reduce items at start up:
