    Windows 10 BSOD WHEAA_UNCORRECTABLE when playing embedded videos

    This BSOD has been plaguing me for awhile now. It happens in a variety of weird instances.

    • Playing videos embedded in web pages
    • Playing videos in Steam
    • Opening the League of Legends Launcher
    • Most recently, I began playing Overwatch and in game, changed the graphics settings to 'Ultra' and it immediately crashed. Now, even opening the game will crash it. I have deleted and reinstalled the game on a different hard drive, it makes no difference.

    My computer is old with some new hardware added on over time (so I guess its just the hard drives that are old. I installed a new SSD where I installed to OS. The other hard drives are from 2010)

    Hi jadors,

    Welcome to the 10forums :)

    This is a generic post for the 0x124 crash, due to the reason why the CPU reported the crash.
    In all the dumps I've looked in the exact same is shown, an internal unclassified error.
    An internal unclassified error means that the error hasn't been publicly documented so we would have to see the documentation of Intel to find out exactly what happened, however this can be time consuming hence the reason why I post a generic version.

    This means that there are problems with your hardware, but this error is also caused by overclocking, faulty drivers or BIOS problems.

    Read carefully before proceeding.

    warning   Warning
    If you're overclocking your system, revert back to stock clocks now.

    Note   Note
    Test the system once the overclock is removed before continuing with the steps outlined below.

    Part Two: MemTest86+ RAM Diagnostic
    Part Three: Hard Drive Diagnostics
    Part Four: GPU Stress Test



    Run Prime95 and/or IntelBurnTest to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 10 Forums & CPU - Stress Test Using IntelBurnTest - Windows 7 Help Forums

    warning   Warning
    Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.



    Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums

    Note   Note

    MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

    Make a photo of the result and post it please.

    If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
    If errors show up and you see them a lot later, no problem, the errors don't affect the test.



    Run SeaTools to check the integrity of your HDD. SeaTools for DOS and Windows - How to Use - Windows 7 Help Forums
    Run following tests
    1. Short Drive Self Test
    2. Short generic
    3. Long generic

    If the short generic fails, no need for the long generic.

    Note   Note
    Do not run SeaTools on an SSD as the results will be invalid.

    Post screenshots/photos of the test results

    Run chkdsk
    Disk Check - Windows 7 Help Forums

    Run HDTune to
    • scan for errors, no quick scan but full scan
    • check the health,
    • benchmark.

    It may take some time, but please take the time you need to perform it properly.
    Let me know what the results are
    • of the error scan,
    • make a screenshot of the health of every hard drive and post the screenshots,
    • post screenshots with the benchmark of the
      • transfer rate,
      • access time,
      • burst rate,
      • cpu usage.

    Best is to make screenshots/photos of these test results too.

    Ran for 3.5 hours with no errors.

    Alright, sorry for the delay.

    I had to get a USB, then life happened etc...

    Anyways, I ran Memtest86 and an error occurred!

    I have attached a screen shot that I took with my phone.

    I know the next steps say to try different RAM slots; how do I know which stick/slot failed?

    Thanks for the quick reply!

    OK, I switched to the 2 other RAM slots and got the same error message. But the message is a bit cryptic - how do I know what slot failed?

    Is it both sticks of RAM or just one?

    The fields I see are:

    Tst Pass Failing Address Good Bad Err-Bits Count CPU

    I dont see where it indicates which slot/stick of RAM is failing (or both).

    Oh - reading up on other forums - am I supposed to now only do 1 single stick and test it in each slot?

    What you see is about the error detected, but MemTest86+ does NOT show what slot/stick is faulty.

    To find out what slot/stick is faulty you need to switch each stick in each (used) slot and run the test each time until either an error is detected or 8 completed passes have passed. This is explained in part 3 of the tutorial.
