    How to find out what caused BSOD?


    I got a BSOD with the message "WHEA uncorrectable error" and nothing else specified
    Then it booted into BIOS repeatedly until I turned off the PC and turned on back again

    Is there a way to check now what caused this?

    Thanks

    As part of the initial BSOD data collection for diagnostics, please perform the following . . .

     BSOD - Initial Data Collection

    [1] Please click the BSOD - Posting Instructions link below.

    • IMPORTANT: Read and follow the Instructions.

    [2] Download and Run the V2 & DM Log Collectors.

    • The log collectors scan necessary files and produce information that will allow us to help you with your issue.

    > BSOD - Posting Instructions

    I am sure that somebody [ @zbook ] will be able to help analyse the output data.

    Thanks.

    Thank you, Chrome blocks the DM logger so I just copied a few Critical and Error logs I see from the same time of the BSOD:

    1) Critical error (There are 4 of them, I guess because of 4 total BSODs so far):

    Also, 1400(yes, thousand+) disk errors in the time before the Critical BSOD happened (like 4 of these identical errors per second)

    Could it be that my NVME is faulty? Or it still can't be determined what's causing the disk to throw errors?

    Hello @mibaup,

    You could check the integrity of the Disk . . .

     Hard Disk Sentinel

    First, check your HDD using the Hard Disk Sentinel Portable Trial Version.

    About HardDiskSentinel:

    HardDiskSentinel is a computer Hard Disk Drive monitoring software for Windows, Linux and DOS operating systems.

    Hard Disk Sentinel [ HDSentinel ] is a multi-OS SSD and HDD monitoring and analysis software. Its goal is to find, test, diagnose and repair hard disk drive problems, report and display SSD and HDD health, performance degradations and failures. Hard Disk Sentinel gives complete textual description, tips and displays/reports the most comprehensive information about the hard disks and Solid State Disks inside the computer and in external enclosures [ USB hard disks / e-SATA hard disks ].

    You can run it directly from a USB, and in my opinion, this gives the best instant report available compared to other software of the same type.

    > Website => Hard Disk Sentinel
    > Download Page => Download Hard Disk Sentinel - Portable

    I hope this helps.

    It's a new Samsung 970 Evo NVME 500GB, does this tool work with NVMEs?

    *Edit: Just saw that it does, will give it a try

    - - - Updated - - -

    Update: Sentinel says my disk is "Perfect"...
    But, still I get those random BSODs and reboot loops into BIOS. And after each BSOD the BIOS does not recognize the NVME. Until a few reboots later it recognizes it again. Is it motherboard hardware issue? BIOS version issue? SSD issue?

    That message does point to some sort of Hardware issue.

    Can you physically check that the RAM is correctly seated. Also, please perform the following . . .

     MemTest86+ - Test RAM

    About MemTest86+:

    MemTest86+ is a diagnostic tool designed to test Random Access Memory (RAM) for faults. MemTest86+ will verify that:
    • RAM will accept and keep random patterns of data sent to it.
    • There are no errors when different parts of memory try to interact.
    • There are no conflicts between memory addresses.

    Memtest86+ runs from bootable media to isolate the RAM from the system, no other components are taken into account during the test.

    I hope this helps.
