GA-78LMT-USB3 random reboots/BSODs with bugcheck 0x124

[rr72]

I recently upgraded a PC that is used for basic tasks and gaming. Unfortunately, the system is randomly rebooting every few days while using Firefox normally. After it boots into Windows, a dialog is shown saying a BSOD has occurred, always with the bugcheck code 0x124: WHEA_UNCORRECTABLE_ERROR. The system is stable in intensive 3D games such as Assassin's Creed IV: Black Flag and in torture tests like Prime95, IntelBurnTest, etc. No components are overclocked. CPU is high 20s C at idle and 42 C at full load, so temperature is not an issue. Voltages shown in BIOS are also acceptable.

System specifications:
- Gigabyte GA-78LMT-USB3 (rev. 5.0, BIOS version FA) -- brand new
- AMD FX-4130 3.8GHz w/ retail heatsink and fan -- brand new
- 8GB (2 x 4GB) G.SKILL Sniper DDR3-1600 -- brand new
- NVIDIA GTX 560 Ti 1GB
- Seagate Barracuda 7200.9 250GB 7200RPM SATA HDD (known good)
- WD Caviar Blue 500GB 7200RPM SATA HDD (known good)
- HGST Deskstar 7K1000.C 1TB 7200RPM SATA HDD (known good)
- Antec Earthwatts 650W PSU (known good)
- Antec Three Hundred ATX Mid Tower
- Windows 7 Home Premium 64-bit

Things tried:
- Tried different known-good DDR3-1333 RAM
- Tried different RAM slots
- Tried different known-good GTX 260 video card
- Tried disabling APM Master Mode in BIOS
- Tried disabling Turbo Core in BIOS

Other people are seeing this same 0x124 code when trying to run certain Steam games on Bulldozer chips (and AMD has acknowledged this in a KB article: http://support.amd.com/en-us/kb-articles/Pages/STEAMGamesonAMDFXplatforms.aspx).. could this be causing the reboots in Firefox I'm experiencing? The article claims I need to upgrade my BIOS, but FA is the latest for my board's revision. Is there a later/beta BIOS that addresses this issue that is perhaps not obvious on Gigabyte's web site?

This is usually heat related, defective hardware, memory or even processor though it is "possible" that it is driver related (rare). I see the brand new parts therefore let me ask you have you performed a fresh install of windows?
That steam article was last updated almost 2 years ago and no longer applies to 99% of systems. Have you downloaded and installed to two patches for your FX processor if not i would do so as they dont come up on windows update that i am aware of.

Update in that order also as 2646060 has to have the top one installed first.

Yes, Windows was reinstalled after the hardware was upgraded.

I came across those Microsoft patches but was under the impression that they were for performance rather than stability. Guess they're worth a try.. as long as Windows doesn't BSOD while installing them.

Resolved. Interestingly, the Firefox BSODs were being caused by the NVIDIA video card driver I was using (331.82 WHQL). I found this thread, which describes the problem: https://forums.geforce.com/default/topic/621899/geforce-drivers/desktop-internet-browser-freeze-thread-w-geforce-460-560-gpus-updated-for-nb-12-5-13-page79-/1. Apparently only 400 and 500 series NVIDIA cards are affected. I upgraded to the 331.93 Beta driver, which has a fix rolled in, and the BSODs disappeared.
