Random BSOD in normal use caused by ntoskrnl.exe

Welcome to SF :) .

A "stop 0x124" is fundamentally different to many other types of bluescreens because it stems from a hardware complaint. Stop 0x124 minidumps contain very little practical information, and it is therefore necessary to approach the problem as a case of hardware in an unknown state of distress. - H2SO4

The generic nature of the 0x124 (Arg1=0) stop code means we would have to take
the trail & error approach.

In this kind of bug check I would like to have a couple more to see if the error is consistent,
the file uploaded only contains one dump file.

The error was a generic memory write error in the L0 CACHE, as I said above one bugcheck is not enough
to establish some sort of pattern.

Code:

What is the make, model and age of your PSU?
Fill out this form and post back the result:

• Power Supply Calculator

Good practice, open up the case and re-seat all types of connection.

• SATA Cables (HDD/SSD/ODD).
• SATA-Power.
• Motherboard 24-pin.
• Motherboard 4/8-pin (CPU).
• Re-seat the RAM.
• Re-seat the GPU.

Make sure that every slot / cable head is free of dust or other obstruction.
Make sure that every connection is seating properly and firmly in-place.


You have an SSD, make sure the following are up to date:

• SSD firmware
• BIOS Version
• Chipset Drivers
• Hard disk controller drivers/SATA drivers
• If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

Test for thermals and stability:

• Download Speccy and post a Screenshot of the summary window, one at idle and another while putting load on the PC using Prime95 for the CPU side and Furmark for the GPU.
  
  • Before running Prime95 make sure to enable Round-off checking (see 1st post under the tutorial).
  
  

Reset the BIOS back to default:

• CLR CMOS

   Note

Write down the current value of the SATA Mode!
Its either AHCI or IDE.
After resetting the CMOS go back and verify the value for SATA Mode is what it was
when the OS was installed.

   Note

If any component is overclocked reset it back to stock speeds!

Thanks for the fast reply!

Power supply calculator said that recommended wattage would be 400W. I have Super Flower Golden Green 550W, so i suppose it's good enough? PSU is 4 months old, just like rest of the components.

Stability should be fine. Pics attached-

I loaded optimal defaults in bios, is that same as resetting it?

I'm unfamiliar with that brand of power supply, I'll ask others about its reliability.

The thermals appear to be in-order, did you follow the tutorial? for how long did you run the tests?
Yes, optimal defaults is the same as resetting to defaults.
Do you have more dump files from previous BSODs to upload?
Did you complete the rest of the suggestions?

Thanks :) , apparently the PSU should suffice in this case.
Apart from the driver (can maybe recall which it was?), can you think of something that was changed
near to when the bug checks began?
I can see that your PC is fairly new, is there an old reused part somewhere in the mix?

I'll be here :) .

You're most welcome :) .
