BSOD playing Diablo III (persisting after uninstall), error 0x00000124

A few days ago, I installed Diablo III, and this was the first time I received this error. It occurs seemingly randomly any time from two hours in to six hours in. Although since the uninstall it has happened just whilst web browsing.

Looking through this thread, I am not overclocking anything, all drivers seem to be updated, the machine is custom build and cooled. The GPU maxes out at 60c when playing, I understand that that is fine.

In the zip file of all the BSOD, there is an earlier one, I'm not sure what it's from and it wasn't recurring, so we can ignore that for the purpose of this thread.

Additionally, all the files of this error are the same size except for one that happened a few hours ago, when I was asleep, which has a slightly bigger file. No idea if that is meaningful.

- ASUS P8Z68-V PRO/GEN3 motherboard
- AMD HD 6670 GPU
- Corsair XMS3 8GB (2 * 4gb)
- Windows 7 x64

The system is about six weeks old.

All of them are unanimous: The CPU failed to perform an instruction execute because it could not read from the L0 cache (which is used to store the solitary line of code to execute).

Make sure that no motherboard software is installed, as they tend to manifest these errors. Only install and update to the latest drivers for all items on your motherboard except port interfaces like USB (these "drivers" are actually software in disguise). You do not nor should you need any of the software that comes with a motherboard. They are grotesquely coded and very gimmicky. Also, if you have no updated the BIOS already, you may wanna do so.

Since this is a CPU failure, you will want to confirm that the CPU itself is not overheating. Also, you may need to remove the CPU and inspect the socket as well as the CPU to see if there are any bent or missing pins. If it's immaculate, then we can confirm for a fact that your CPU is bad. As for my suspicion, I have little doubt that we're dealing with a bugged CPU. May wanna get it replaced if at all possible.

Analysts:

Same fatal error for all of them, including running core and bank (obviously the same bank since L0 I believe only has one):

Anything that doesn't relate directly to operating devices in the Windows environment constitutes as software. For example, you may have device drivers for your onboard audio in order for it to work, but they may also provide software to add extra - and often superfluous - features. Likewise, chipset suite drivers may include stuff like drive controller drivers to have your storage devices work properly, but it may also include misc. stuff like temp monitor software and all that jazz. Again, anything that isn't required to get your device to work on your PC is software. Note, again, that USB and other interface "drivers" are unnecessary. Windows standard drivers for these works perfectly, the drivers included with your motherboard software just adds extra junk like faster recharging of devices and whatnot. They are marketing gimmicks and never actually improve anything and only make your system unstable.

As for updating the BIOS, yes, if you have a faulty CPU - which I believe you have - it's probably not the best idea to update the BIOS right now. A bad or old BIOS may be the cause of your problems, but I personally extremely doubt it. Your CPU is mostly at fault here, so you'll want to get it replaced and get things a bit more stable prior to updating the BIOS.

Okay, thanks so much. Speaking with Amazon at the moment.

I really appreciate your help.

Edit: I don't think I have any of that.
