Semi-random BSOD need help narrowing down the cause

If you are using a program like Ccleaner please stop using it while troubleshooting.
This because programs like Ccleaner remove dump files that are needed to troubleshoot.
Or configure Ccleaner to not remove dump files:



Unfortunately, only 1 minidump is present. 1 dump isn't enough for proper analysis with a 0x124.
All there is in the single minidump is a write error on the level 0 cache of core 2, but this doesn't say much.
Please follow instructions below carefully.

The error is 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 to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 10 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 passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking forzero errors here. Even a single error will indicate RAM failure.

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.

Run chkdsk

• 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.

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.
