Windows 7: BCCode 124 and A4

25 Feb 2010   #1

Windows 7 Professional x64
BCCode 124 and A4

Well, it's been about three weeks since a host of problems came up, so I'll give you a synopsis:

Around Feb 14th, I started having a host of new issues. After uprooting a retro virus through some old files (CMOSKill.d, in particular), I started getting a host of various errors (most of which I could identify were 124). After a few days, I checked out my hard drive, finding a few corrupt sectors (22 and rising), so I bought a new drive and did a fresh install of Windows 7. About a day later, my machine started failing again with a variety of errors (see: ).

Yesterday, I got a few new errors: BCCode 124 and STOP 0x000000A4. 124 is terribly vague as far as errors go, but the 0xA4 really was unusual to me. And this also caught me off guard:

A fatal hardware error has occurred.

Component: AMD Northbridge
Error Source: Machine Check Exception
Error Type: 11
Processor ID: 0

The details view of this entry contains further information.

(See SkyDrive link for detailed view)
The error happened while I was in-game, and the only time I can recall it happening on my new install. It worked similarity to the other errors, causing a sound/graphics lock up followed by the machine shutting off everything except itself, just hanging in what I can describe as a "pre-POST state".

Anywho, down to brass tacks:

Setup (All stock settings):
ASUS M4A77TD PRO Motherboard
AMD Phenom II x2 545 (Callisto), 3.0 GHz/core
HIS ATI RADEON 5770 (Running 10.2 Catalyst drivers)
650 W Corsair PSU

Windows Live SkyDrive

-CPU/Memory voltage/timings/clock stuff
-Five dump files of various errors

(Dump 022410-18018-01.dmp is probably of particular interest; that is where the Machine Check Exception happened.)

I've applied new thermal paste to the heatsink, and nothing seemed damaged externally when looking at the CPU, so, if anything, what could be wrong?
