Understanding the issue

[zakyr]

I've had this problem for quite some time now, and I've been unable to get to the root of it.

Short version: Whenever I play APB with sound, after 30-40 minutes the game crashes. And the only way out of it is hitting the reset button, no ctrl-alt-del'ing out of it. Though it works fine when I disable my sound card (Realtek) in device manager.

The details are as follows. At the bottom are links to the related .xml and .dmp files for those who could read and understand the technical stuff.

I've heard that some games require the audio quality changing for them to even load, try dropping the levels and see if it still happens

A 0x124 dump is WHEA_UNCORRECTABLE_ERROR, which means there was a hardware error the CPU couldn't fix, and Windows was told to halt by the CPU due to this (if you have a hardware error that is *correctible*, Windows will keep running but log an event log entry in the system log under ID 19, a WHEA_CORRECTABLE_ERROR log, fyi).

In looking at the error record from the dump you posted, I see this:

Proc. Info 0  @ fffffa80048cf960
===============================================================================
Section 2	 : x86/x64 MCA
-------------------------------------------------------------------------------
Descriptor    @ fffffa80048cf858
Section	   @ fffffa80048cf9e0
Offset	    : 664
Length	    : 264
Flags		 : 0x00000000
Severity	  : Fatal
Error		 : [b]BUSL0_SRC_ERR_M_NOTIMEOUT_ERR[/b] (Proc 0 Bank 0)
  Status	  : 0xf200004000000800

That error (BUSL0_SRC_ERR_M_NOTIMEOUT_ERR) means the processor sent out a read request to L0 cache, and there was a delay in return (either a cache miss, or invalid data in cache). If !cpuinfo is correct, your system does indeed have a 2.4GHz E4600 Core 2 Duo:

1: kd> !cpuinfo
CP  F/M/S Manufacturer  MHz PRCB Signature    MSR 8B Signature Features
 1  6,15,13 GenuineIntel 2419 000000a300000000				   211b3ffe

Given this part isn't overclocked, that would lend more credence to a cache issue on the CPU itself. You can try to increase voltage to fix it (not guaranteed to do so, though), and that can have some side-effects on the expected length of life of the part, or you can replace the CPU (either under warranty or otherwise). It stinks that this is audio-related, and workarounds might get your system to the point it doesn't crash, but that won't remove the fact you may have a hardware issue here.

Thank you. This certainly puts things in perspective.
