Frequent BSoD for ntoskrnl.exe, dxgmms1.sys when watching yt, twitch

I've been suffering BSoDs relatively frequently for a while now, in my perception mostly when watching streamed flash video such as from YouTube or Twitch.tv.
Multiple system wipes/fresh installations have not resolved the issue.
RAM replacement seemed to allow me to catch a break at first, but BSoDs returned after few days of calm and I suffered 3 of them during the last 2 days. Western Digital Data Lifeguard Diagnostics and MemTest (ran multiple copies simultaneously for 8 hours) returned no errors.

According to the dump files, BSoDs were caused by a combination of ntoskrnl.exe and dxgmms1.sys.
Again, in my imagination most of them they seem to coincide with streaming flash video via Twitch.tv, which I watch using multiple instances of Google Chrome and Firefox. Although that might be completely unrelated.

As a layman, I'm puzzled, and thus turn to you for your insight and help.

Please start by removing the following programs from your computer:

Code:

Start Menu\Programs\DAEMON Tools Lite

Once Daemon tools is gone please download and run this tool:

DuplexSecure - Downloads

When the tool runs if the uninstall button is grayed out your done and can close the window. If it is not please click it and allow the tool to do its job. DO NOT click the install button it will install a driver known to cause BSODs.

Also uninstall this program it is likely doing more harm than good:

Code:

Start Menu\Programs\TuneUp Utilities 2013

Next please update the following drivers thaey are potentialy problimatic:

Code:

fffff880`0c9fc9c8  fffff880`07308dbf*** WARNING: Unable to verify timestamp for atikmdag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys
 atikmdag+0x7ddbf

Driver Reference Table - atikmdag.sys

update it from here:http://support.amd.com/us/Pages/AMDSupportHub.aspx

Code:

fffff880`02f1a598  fffff880`041a0010Unable to load image \SystemRoot\system32\DRIVERS\Rt64win7.sys, Win32 error 0n2

*** ERROR: Module load completed but symbols could not be loaded for Rt64win7.sys

Driver Reference Table - Rt64win7.sys

Please update this driver from here: Realtek

Tune up utilities, like many other "tune up" software it does things that windows 7 already has built in tools for, or does automatically rendering it utterly useless, further more it also does thing like and I shudder when I say this "cleans the registry" now this is literally the worst possible thing you can do with a program, the program knows less about your registry than you do. In the end it will end up deleting something it shouldn't and then the only option is a re-install of windows. if you want to figure out what conflicts there may begoing on in the system follow this tutorial:

Troubleshoot Application Conflicts by Performing a Clean Startup

Glad I could be of help.

Ok a couple of things to try:

Fist run the system file checker to help clear up any file system corruption

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.

when the program finishes running if it says anything other than no integrity violations found run it twice more.

then from the same command prompt run the following command:

Code:

chkdsk /f /r

and last try updating your BIOS it is very old

Code:

BIOS Release Date             08/05/2009

The BIOS updates should be available from the Motherborad manufacturer on their website.

SFC.EXE /SCANNOW (no integrity violations found) and Chkdsk returned no errors. BIOS has been updated.

Even so, another Blue Screen occurred, again dxgmmms1.sys, again while watching a stream.
WhoCrashed says "This appears to be a typical software driver bug and not likely caused by a hardware problem. [...] Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time."

So far I've wiped the machine and reinstalled Windows, replaced the RAM,
ran multiple instances of MemTest simultaneously for 8 hours as well as Western Digital Data Lifeguard Diagnostics, SFC.EXE /SCANNOW and Chkdsk without them returning errors.
Graphics (amd.com via amddriverdownloader.exe) and
sound driver (realtek.com via ALL_INST_1.12.0022_DASH_20110922_B1) and
BIOS (gigabyte.de via F8/Update AM3 CPU AGESA 3.7.1.0) have been updated. There's a F9b BIOS version from 2012/08/14, but it says "Beta BIOS", so I didn't touch it.
I also disabled all non-Microsoft services in msconfig to see if one of might be the cause.

Odd tthe dump files are still pointing to your Graphics card drivers as the issue, but they are up to date, for testing sake, and to hopefully rule out hardware problems plese do the following:

Run furmark to stress test the Video card, and check for over heating:
FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

FurMark Setup:
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature" (BurnIn test in newer versions).
Click "Go" to start the test
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
- Click "Quit" to exit

please rport your tempeartures prior to starting the test, and when the heat maxes out (if the stress test doesnt cause a crash)
Then run this program to test the dedicated memory on the video card:

This test is very straight forward, no need to change any settings when it runs just let it do its thing for 8-9 passes. Report any errors that occur during the test or if it causes a crash.
