    Please post a new beta log collector zip using extract followed by open:
    log collector v2-beta08.zip
    See if it can work with different browsers.
    If it does not open to collect the logs then use the DM log collector:

    1) Please increase the free space on partition C: to 30 - 35 GB or more.
    2) In the left lower corner search type: msinfo32 > allow several minutes for it to fully load > save to desktop as a NFO file > zip > post a link into the thread
    3) Run memtest86+ version 5.01 for at least 8 passes. Memtest86+ - Advanced Memory Diagnostic Tool
    This may take hours so plan to run it overnight.
    a) Please make sure you use the Memtest86+ version 5.01 with the link below.
    Memtest86+ - Advanced Memory Diagnostic Tool
    The testing is done not by time but by passes.
    The more passes the better.
    There are a significant number of false negatives if fewer than 8 passes are made.
    A false negative is a test pass when there is malfunctioning RAM.
    There is 32 GB of RAM on the computer. There is 8 GB on each of 4 DIMM.
    Label each RAM module.
    Remove 2 RAM modules and perform 2 separate tests with 16 GB RAM during each test.
    Perform the testing so that all RAM and all DIMM are tested.
    Testing must be continuous.
    If you have sufficient time to test all RAM modules at the same time (32 GB RAM) that is the best testing as it will test RAM / DIMM / motherboard including multichannel capability.
    The multichannel capability can be checked with 2 RAM modules.
    Memtest86+ version 5.01 testing takes approximately 1 - 2 hours /GB RAM
    Just 1 error is a fail and you can abort testing.
    Then test 1 RAM module at a time in the same DIMM each for 8 or more passes.
    b) When Memtest86+ has completed 8 or more passes use a camera or smart phone camera to take a picture and post an image into the thread.

    Hello,

    sorry for taking so long to reply.
    Here's the msinfo report (file upload doesn't seem to work anymore on the forums): Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

    1. I labeled RAM modules 1 to 4
    2. I removed modules #3 and #4 and started memtest. See result:

    3. I started my computer and it booted fine. Restarted it multiple times with no issues - been working with it for a week, I couldn't continue the time consuming memtest due to work. Today I turned off my computer to see if I can reproduce the issue
    4. I removed the power cable so as to cut power to my computer, then I plugged it back
    5. Turned on my computer and got black screen - no video output. The same boot issue.
    6.1 Removed RAM module #2
    6.2 Turned on my computer, booted fine (got to bitlocker screen)
    6.3 Turned off my computer
    6.4 Put RAM module #2 back to where it was
    6.5 Computer booted fine, and now I'm writing this post

    zbook, there seems to be no point in running more memtest as the two modules that I have now have passed it and I still face the same issue. Please advise.

    Can anyone make sense of this? It'a recurring pattern that once I cut power, it fails to boot until I remove one RAM module. Then it works fine even if I restart it, or turn it off and put all RAM modules back.

    I wonder if that problem lies within your monitor, sometimes as they age or through daily use they sometimes cannot sense the PC / Gfx starting up. It's easy but cumbersome to test with a spare..

    No it's not that.
    1. I have two monitors, both act the same
    2.1 Computer restarts
    2.2 if it does not restart, it acts differently - the keyboard does not light up

    1) RAM modules 1 and 2 passed (16 GB, 10 passes).

    2) The plan now is to test the Drive and then test the drivers.

    3) Once all of the non-Microsoft drivers are tested and do not BSOD the hardware will be tested.

    4) Make a backup image using Macrium: (communicate into the thread once the backup has completed)
    Place the backup image on another drive

    5) Make sure the C: drive has 30 -35 GB or more of free space

    7) Make a brand new restore point (communicate into the thread once it has been completed)

    8) Read these links on Windows driver verifier: (Do not use the tool until it is communicated in the thread)

    a) Driver Verifier-- tracking down a mis-behaving driver. - Microsoft Community

    b) Enable and Disable Driver Verifier in Windows 10 Windows 10 Tutorials

    9) Run HD Tune:
    http://www.hdtune.com/
    Post images into the thread for the test results on these tabs:
    a) Health (SMART)
    b) Benchmark
    c) Full error scan

    10) Update the specs in the "My Computer" section:
    System Specs - Fill in at Ten Forums:
    System Specs - Fill in at Ten Forums Windows 10 Tutorials
    In the left corner below in your post you find 'My System Specs'.
    After clicking it you can find a link a little below that says 'Update your System Spec', click on this link to get to the page where you can fill in your system specs.

    Include PSU. cooler, case, peripherals and anything attached to the computer by wired or wireless (mouse, keyboard, headset, printer, xbox, USB wireless network card, etc.)

    11) Choose one of the temperature monitoring software applications: Speecy, HW monitor, Speed fan:

    Yes

    zbook, not sure I'll manage to start this today, so I'll drop a quick question first. How much driver-wise do windows actually load to get to bitlocker password screen? Could this perhaps help narrow down the search?

    10) The minimum configuration to get into my bootloop issue is with no peripherals. But I still added keyboard, cooler and mouse fields

    For drive performance aim for 20 - 25 % free space.
    Windows will automatically delete Memory dump files when free space is < or = 25 GB.
    Windows upgrade may fail if free space is < 20 GB.

    For a 125 GB drive 25% free space is 31 - 32 GB.
    During the troubleshooting process please maintain free space so that it is 30 - 35 GB or more.

    There are 3 methods to turn off or recover from using Windows driver verifier.
    All methods use the Windows advanced troubleshooting menu.
    1) startup options (not startup repair) > click restart > select #6 safe mode with command prompt > type:
    verifier /reset
    2) command prompt > Administrator X:\Windows\System32\cmd.exe > X:\Sources> type:
    verifier /bootmode resetonbootfail
    3) system restore
    The methods used to turn off Windows driver verifer should be used in the above order. Only advance to the next method if the prior method fails. Using system restore often leads to a loss of the dump file and little progress is made in the troubleshooting.

    When you feel comfortable using the tool and have made a brand new restore point you can start using it.
    For any BSOD > run the beta log collector > post a zip into the thread.
