BSOD with Flash: BCCode 7f

Hi, happy new year!

I am able to consistently induce a BSOD while playing a Flash game (or watching something in a Flash player) in a Firefox browser window. It may be coincidence or a third factor, but so far that's the constant thread. It isn't an immediate crash, but it will crash after not much time.

This problem is new. The hardware is all relatively old, and has been relatively stable for some time (prior to this, obviously). No major software installs that I know, but there is always been the endless streams of updates to Windows, Firefox, Flash, Java, etc. I recently uninstalled several programs to make room for a different program on the SSD drive.

I've tried a few diagnostics/fixing programs to clean this up, but nothing successful thus far. I.e. I've fixed some problems, but the BSOD still happens.

• Spybot S&D
• Microsoft Security Essentials
• Malware Bytes Anti-Malware

This is a pretty typical error:

SF diagnostic grab is attached. Please let me know if there is more information needed to help find & fix this problem.

Some additional info...

System Specs (for convenience) custom build:
Win 7 Pro 64-bit (OEM)
ASUS P8 Z77-V Pro LGA1155 motherboard
Intel Core i5-3550 CPU (3.3 GHz)
GSkill 8 GB RipsawsX DDR3 1600MHz (2 sticks @ 4 GB each)
ASUS ENGTX570 DCII/2DIS/1280MD5
OCZ Agility 3 SSD (120GB) as primary HD
850W NZXT Hale90-850-M PSU

Obviously I still don't know what the problem is, but I've ruled out a few things (at least based on first brush).

It does not appear to be:

• Overclocking - The system is set to factory speeds. It has never been overclocked.
• CPU hardware - I ran an 8 minute stress test using Prime95. Zero errors.
• Temperature - CPU and GPU have been pretty steady near 30 C according to RealTemp. The CPU held steady near 60 C during the stress test, and dropped back down to 30 reasonably soon after ending.
• System memory hardware - I ran the windows memory diagnostic twice. Zero errors.
• SSD hardware - I ran checkdisk twice - once in Windows and once on boot. Zero errors.
• System files - sfc found zero problems.

Perhaps the most interesting thing that's happened so far is running msert.exe (Microsoft Safety Scanner). That program crashed when running a full scan. The quick scan detected zero problems.

I'm not sure Flash is the common factor anymore, as the computer has now crashed twice on me while attempting to create this reply. Third time's the charm...

With my previous failure to find a cause, I reinstalled windows. It was supposed to be a clean install (done without reformatting C: ).

A recent FurMark test revealed a new artifact. It was roughly 200 pixels wide by 50 tall. It looked like snow from an old TV. It wasn't constant, but seemed to jerk in and out. There may have been some minor tearing in the outer pattern as well, it appeared to jump partway through the cycle without a smooth transition.

Will upload an updated zip in the next post.

I really don't even know where to start looking to fix this. There are a lot of things it *could* be, but so far I've narrowed it down to "something in that case is broken." Not a good place to be, and it seems to be getting worse.

Any clues or advice?

An update to current status... While thinking that one of the Blue Screens could have caused a problem with my previous install, I reinstalled windows with a reformat of the primary partition on the SSD.


Current installs include:

• OS Win 7 64 bit with Service Pack 1 (no additional updates)
• NVidia driver 314.22 <-- reported to be one of the most stable drivers, hopefully to eliminate that as a variable
• Chipset and network drivers from the motherboard CD
• USB3 driver as recommended by the Action Center (independent of crashes... crashes happened before, crashes happen now)

These blue screens only seem to happen while browsing the internet. Often it crashes as the browser is being launched, or shortly thereafter. So far, no crashes in Safe Mode. I am posting this from Safe Mode. So far, no problems while using game applications (Diablo II, World of Warcraft tested so far... could test Civ IV and Battlefield 4). I copied several folders to the larger D: to save install time; I know several of these programs work just fine without all the reg files and can be played off of thumb drives.

*Windows is no longer creating minidump files* Not sure why that is, but it isn't. New SF Diagnostic uploaded.

Outside of swapping parts, is there any decent way to narrow down the scope of the problem?
