WHEA_UNCORRECTABLE_ERROR while playing games

I recently installed Windows 8.1 on my PC.  I've had nine BSOD's so far, all while playing World of Tanks (that's the only game I've been playing).   The blue screen says WHEA_UNCORRECTABLE_ERROR.  I've tried troubleshooting myself, but I can't figure out what the problem is.  What should I do?


Thanks very much for the Kernel!

It's of the WHEA_UNCORRECTABLE_ERROR (124) bug check.

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

If we run an !errrec on the 2nd parameter of the bugcheck (address of the WER structure) we get the following:

Section 0     : Processor Generic
Descriptor    @ ffffe000043df0a8
Section       @ ffffe000043df180
Offset        : 344

^^ Cache Error, let's go further...

Section 2     : x86/x64 MCA

  Address     : 0x000000011a11c900
  Misc.       : 0x0000000000000086

^^ The specific type of error is DCACHEL0_WR_ERR. This implies a L0 Cache Write error.


There is only so much you can do with a bugcheck like this until it comes down to a faulty processor that will need to be replaced. Start from 1 and work downward:

1. Ensure your temperatures are within standard and nothing's overheating. You can use a program such as Speccy if you'd like to monitor temps - http://www.piriform.com/speccy

2. Clear your CMOS (or load optimized BIOS defaults) to ensure there's no improper BIOS setting - http://pcsupport.about.com/od/fixtheproblem/tp/clearcmos.htm

3. Ensure your BIOS is up to date.

4. The only software conflict that can usually cause *124 bugchecks are OS to BIOS utilities from manufacturer's like Asus' AI Suite. If you have something like this software-wise, remove it ASAP.

5. If all of the above fail, the only left to do is replace your processor as it is faulty.
