Windows 10 BSOD WHEAA_UNCORRECTABLE when playing embedded videos

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.

The error 0x124 WHEA_UNCORRECTABLE_ERROR (Windows Hardware Error Architecture)
This means that there are problems with your hardware, but this error is also caused by overclocking, faulty drivers or BIOS problems.

STOP 0x124 Troubleshooting

Read carefully before proceeding.

   Warning

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

   Note

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

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

ONE

 CPU 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

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

TWO

 RAM TEST

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

   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.


Addition:
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.

THREE

 HDD 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

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.

FOUR

 GPU TEST

Run Furmark to stress test your GPU. FurMark - GPU Stress Test - Windows 10 Forums

   Note

Run Furmark for around 30 minutes.

   Warning

Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them and abort the test if overheating occurs.

Keep me posted

ow do I know which stick/slot failed?

That is explained in part 3 of the tutorial

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.
