The stop 0x124 problem started out of the blue two days ago and only occurs when im playing games such as WoW or CSGO. Otherwise, when i'm watching videos on youtube or downloading things, theres no blue screen, but after half an hour to an hour into gameplay, I get the 0x124 BSOD. Rebooting my system and restarting my game causes another bluescreen to happen roughly around 10-15 minutes of gameplay.

Thanks alot for your time.

Hi,

WHEA_UNCORRECTABLE_ERROR (124)

A fatal hardware error has occurred. This fatal error displays data from the Windows Hardware Error Architecture (WHEA).

Code: 
===============================================================================
Section 2     : x86/x64 MCA
-------------------------------------------------------------------------------
Descriptor    @ fffffa80071f1138
Section       @ fffffa80071f12c0
Offset        : 664
Length        : 264
Flags         : 0x00000000
Severity      : Fatal

[COLOR=#ff0000]Error         : Internal unclassified (Proc 2 Bank 4)[/COLOR]

Internal unclassified, essentially implying it's not publicly documented.

Likely a hardware problem, mainly CPU. I'd uninstall Daemon Tools and any/all Asus bloatware for starters to eliminate any potential software conflicts.

Hi,
I've tested my cpu using prime95 and it didnt show any issues.. I had daemon tools lite but just uninstalled it and the only asus software I have is a network adapter for a usb wifi adapter from asus.

If the BSODS continues after doing so, how should I proceed?

All the best.
 
We can test RAM before labeling CPU. Even if P95 passes it's not an automatic pass for stability. Most 0x124's are caused by hardware, specifically CPU. Again, given it's an internal unclassified, it's almost impossible to know (especially considering it's a minidump).

Run Memtest for no less than 8 passes to see if your RAM is okay:

Memtest86+:

Download Memtest86+ here:

Memtest86+ - Advanced Memory Diagnostic Tool

Which should I download?

You can either download the pre-compiled .ISO that you would burn to a CD and then boot from the CD, or you can download the auto-installer for the USB key. What this will do is format your USB drive, make it a bootable device, and then install the necessary files. Both do the same job, it's just up to you which you choose, or which you have available (whether it's CD or USB).

Do note that some older generation motherboards do not support USB-based booting, therefore your only option is CD (or Floppy if you really wanted to).

How Memtest works (you don't need to read, it's only for those interested in the specifics):

Memtest uses algorithms (specifically two), namely moving inversion & what is deemed Modulo-X. Essentially, the first algorithm fills the memory with a pattern. Starting at the low address, it checks to see if the pattern was changed (it should not have been), writes the patterns complement, increments the address, and repeats. Starting at the highest address (as opposed to the lowest), it follows the same checklist.

The reason for the second algorithm is due to a few limitations, with the first being that not all adjacent cells are being tested for interaction due to modern chips being 4 to 16 bits wide regarding data storage. With that said, patterns are used to go ahead and ensure that all adjacent cells have at least been written with all possible one and zero combinations.

The second is that caching, buffering and out of order execution will interfere with the moving inversions algorithm. However, the second algorithm used is not affected by this. For starting offsets of 0-20, the algorithm will write every 20th location with a pattern, write all other locations with the patterns complement, repeat the previous one (or more) times, and then check every 20th location for the previously mentioned pattern.

Now that you know how Memtest actually works, it's important to know that the tests it goes through all mean something different. It goes from Test 0 through Test 12, many of which use either one or the other algorithm discussed above, among many other things.

Any other questions, they can most likely be answered by reading this great guide here:

Hi there,

So I've tried reinstalling windows and then running WoW. I get a blue screen about 3 minutes into playing.
Is there anything else besides running memtest I can do to fix my problem?

Thanks.
