    Lenovo K450 Win8 Frequent BSOD

    I have been chasing an issue with my new Lenovo K450 frequently crashing (6-8 times daily) with random errors displayed on the BSOD.

    Lenovo have been zero help thus far after having me re-install Windows from scratch and performing all updates.

    I have dozens of minidump files stored.

    If anyone here can have a look at the included SF DIAG TOOL info and offer assistance, I would be very thankful.

    Please try the below steps.

    1. Uninstall GenesysLogic GeneStor.

    This driver seems to be directly blamed in the last crash dump.

    BugCheck 1000007E, {ffffffffc0000005, fffff8027f2aebe7, fffff88005fc07c8, fffff88005fc0000}
    *** WARNING: Unable to verify timestamp for GeneStor.sys
    *** ERROR: Module load completed but symbols could not be loaded for GeneStor.sys
    Probably caused by : GeneStor.sys ( GeneStor+790b )
    After uninstalling the driver, disconnect the device from USB port.

    2. Update TeamViewer.

    TeamViewerVPN Network Adapter
    Update it from TeamViewer - Free Remote Access and Remote Desktop Sharing over the Internet

    3. Update LAN and Wireless LAN drivers.

    Let's check whether it makes any difference.

    Varying BSOD can be an indication of a hardware issue, especially failing memory modules. Please run a memory diagnostic test using the free tool "Memtest86+".

    Latest version : Memtest86+ - Advanced Memory Diagnostic Tool

    Guide : RAM - Test with Memtest86+ - Windows 7 Help Forums

    This test may take several hours to complete depending on the amount of RAM. Fir an accurate result, a minimum of seven passes is required. More passes will give us better result. You can stop the test even if a single error is found. Otherwise let it complete 7-10 passes and post a clear screenshot (use a cam or cell phone) with next reply.

    All RAM was previously replaced without improvement.
    When was the RAM modules replaced ?. Before or after the blue screens started ?.

    RAM replaced last week, well after BSOD began.

    RAM test running now.

    Although the RAM is new, there is still a chance for memory related issues like a bad memory slot etc. So it is always good to stress test the RAM when in doubt.

    If the RAM test came clean (7 -10 passes) , please do the below steps.

    1. Scan for malwares.

    Malwarebytes free : Malwarebytes Anti-Malware Download (Full scan )

    Kaspersky TDSS killer : TDSSKiller Rootkit Removal Utility Free Download | Kaspersky Lab US ( a quick one minute scan to find rootkits)

    ESET Online Scanner : Using ESET's Online Scanner - MajorGeeks Support Forums (as per the guide).

    2.In your next reply, please include a "Speccy" snapshot of your system along with the memtest screenshot.

    Publish a Snapshot using Speccy - Internet Applications Mini-Guides

    (the web link it displays).

    Please try the below steps.

    1. Reset system BIOS.

    How To Clear CMOS (Reset BIOS)

    After resetting, load "Optimal default values".

    2. Enable "Diver Verifier".

    "Driver Verifier" is a Microsoft's own tool to stress test third party drivers and find faulty ones. Please read instructions from the below link for detailed info.

    Driver Verifier - BSOD related - Sysnative Forums

    After enabling the "Verifier" , system will blue screen if a buggy driver is found and the dump will contain info about the offending driver. After you got two or more blue screens, upload the new crash dumps for inspections. If the "Verifier" enabled dumps are also blaming Windows system files, it is considered as a clear sign of low level hardware issue.
