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 for zero errors here. Even a single error will indicate RAM failure.

THREE

 HDD TEST

Run SeaTools to check the integrity of your HDD. http://www.sevenforums.com/tutorials...s-how-use.html

   Note

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

Run chkdsk http://www.sevenforums.com/tutorials...isk-check.html

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.

Good stuff, proceed with the other tests at your convenience.
