Need Help with blue screen error 124

Welcome to SF kishanprs :).

I have a question if I may.
All of the bugchecks are 0x124, which are hardware related, and all of them are showing
a generic L2 Cache error. But the intriguing part is that they all occurred in the span
of roughly three hours, what changed recently in you system?

Attachment 303377

Thanks for the added info :).
I recommend starting with some stress tests for the GPU, CPU & RAM.

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

• Power Supply Calculator

Test for thermals and stability:

• Download HWinfo and post a Screenshot of the sensors 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).
  
  
     Note

  It is not mandatory to run both tests simultaneously, although possible as long as the temperatures are under constant monitoring.

Testing the RAM:

Test and Diagnose RAM Issues with Memtest86+:

• RAM - Test with Memtest86+

   Tip

• Pay close attention to part 3 of the tutorial "If you have errors"
• Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

When done with the testing procedure take a picture and upload it here.

This will help you to determine where the issue is origination from (if any):

First run it with all the existing/installed RAM modules. If it comes with no error, all is good.

But if it starts showing errors, Stop testing. Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:
No code has to be inserted here. It is a RAM, a bad RAM.

But if you have got a result like that:
No code has to be inserted here. It is a motherboard issue. The particular slot is bad.

Let us know the results.

Yester days I did a clean re-install on the system, seems to be fine for now. But every time I try to run the Prime95 I get the same Blue screen with 124 error. I have attached the results of other testings.

Power Supply : Coolmaster 750W ( about 2 years old) I set 15% for capacitor aging.

I have done a Asus UEFI memory test and shows no errors.

Thanks for the update :) .

The sources I can see are the PSU (power supply) / Motherboard and CPU although pretty rare
it is a possibility.
Can you borrow or own a PSU you can stress-test the CPU with?

I will look in to it, or what if i disconnect few chassis fan/ dvdroms and run the test?

Lowering the total Wattage draw is a good test but a few fans and an optical drive won't do much I believe, on the other hand the GPU should have a grater impact.
