    Tested the memory last night, it passed.
    Good idea re. DEP, just turned it off, no change.
    Can you tell me what software library is a prerequisite? .Net , Visual C++ redistributables?
    I'm about to run some GPU stability test withMSI Kombustor, back later with the results.

    Obviously the OpenAL library--installer in utilities.

    And the microsoft VC++ redistributables (the x86 versions) (2012): http://www.microsoft.com/en-us/downl....aspx?id=30679 One person said he ALSO had to install the 2010 version, which seems a bit odd but it did get him working...

    OK thanks. When I installed W7 on a new hdd for the test a couple of days ago. I'd installed 2012 first, but needed to install 2010 version too.
    I'll repeat that if you like.

    I sent most of today running the MSI Afterburner and playing with the clock speeds. I've established that:
    I can force an immediate crash in RogSys by overclocking the GPU core from 800 Mhz to 820Mhz
    It becomes completely stable if I underclock down to 750Mhz.
    However in other programs, I can push the overclock higher and they're stable.

    Running the MSI Kombustor stress tests, has shown that the CPU and GPU are rock steady at 100%, fans blowing a gale for a good 4 hours.
    Some of the tests specifically target the OpenGL features.
    I've also run GPUTest 0.7.0 from http://www.geeks3d.com/gputest/ which includes a suite of OpenGL render stress tests.
    I'm now happy the graphics card is capable of running an OpenGL based program under high stress loads without crashing.

    So the problem isn't in the OS, HDDs or GPU imho.

    I'm going to look at the mobo bios next, but that may be Monday, as it's Fathers Day in the morning and I doubt if my girls would take kindly to me locking myself away!

    Thanks for the update. From what I've been reading that's the funny thing about this--it hits (seemingly) random nVidia users, and in many different programs--OpenGL and DirectX alike. What's worse, it never seems to have one distinct cause/solution.

    I have to wonder if nVidia recognized a "problem" at some point, and so they added the TDR error to catch it so it wouldn't hang the system? I don't know...

    Becoming stable when under-clocking is interesting. At least it let's us know there's not an issue with the shaders, etc. If there were, the clock-speed wouldn't make a difference--the GPU would choke them regardless.

    Thanks again! Yeah--Angel and my daughters have informed me in no simple terms that I'm not allowed to work on Father's Day, either

    Found a fix.

    I've removed the overclock of the GPU that was set by the factory.
    It's a MSI GSX 580 Twin Frozr II O/C model, so I've just set the core and memory back to stock values and increased the core voltage a bit. http://forums.overclockers.co.uk/sho...php?t=18339671
    I think the more important value in this case, is the core voltage which is now running at 1050mV, up from 1038mV, thus supplying the card with more power.
    The stock value for the core clock is now down to 772MHz, from 800MHz and the memory clock down to 2004MHz, from 2048MHz.

    I'm guessing I could experiment with upping the core and memory speed, but will at some point hit the instability and / or max temps.
    Reading around, there seems to be a variation of figures these cards come out of the factory with and two supposedly identical card models, can in fact be running at different speeds. I know overclocking can be more art than science and this could explain the variation of the nVidia experience .

    Hope this helps others with similar issues and thanks for the suggestions.

    THANK YOU! I will post this in the troubleshooting guide as a potential, interim fix. My hope is that when the planetary shaders are optimized this MIGHT help the situation. The fact that they do work in the front-end though would lead me to believe otherwise.

    From time to time I might give you a shout to try the settings your card came with from the factory to see if any improvement has been made. In the meantime, I can't thank you enough for working through the issue as you did, which may potentially help other nVidia users out!

    If it was an issue at my end, I was confident I'd find it, sooner or later!
    I've always enjoyed the diagnostic hide and seek.
    Although, the solution always seems to be the last thing you try on the list - lol!

    It may be wise to include a warning regarding altering GUI voltages. You know the sort of thing ....

    Hello.
    I have a problem with launch a game. Can you help me? I install the game from Steam. Install newest nVidia drivers. I done all that found in this and some others forums.

    P.S. sorry for my english.
