  • Crash to desktop midgame with Access Violation minidumps

    Hey, for the last little bit, I'll be playing in matches, and all of a sudden my game will crash to desktop without warning, no prompts or anything. Just closes. It happens randomly from maybe not at all one day, to up to a dozen times a day. I do not know how to open/view/understand the .mdmp files but here's the link to the zip. There are 10 of them in the zip.

    https://drive.google.com/file/d/0B74...ew?usp=sharing

    I have most recent OS updates (Windows 10 64bit), and most recent GPU Drivers (ASUS Radeon R9 280x). I have even tried installing on a new drive, to see if it helped, it has not. It now lives on my gaming SSD, was previously on a WD Black drive.

    Any help would be extremely appreciated, because I am afraid to play ranked games with this striking at any moment.

    Thanks in advance!

    Those are all random DEP errors - check your RAM! (using a bootable usb/dvd with memtest86+ for at least 2-3 loops)
    Dump shows a laptop CPU - this can also be a sign of insufficient cooling/power wear - downclocking/downvoltaging might help with that.

    Note that latest AMD driver is not very stable, you might want to get back to pre-Crimson versions.
    Note that most of the dumps had OBS recording in the background, you might want to adjust it's settings (check their forums) or even close it.

    You should stick with launch options -dx11 -noborder or -nod3d9ex -noborder and for troubleshooting, might add -32bit

      Odd. My CPU is an Intel 2600k, and has not been overclocked at all, I will check the RAM.
      I have suspected maybe OBS + Dota was straining my GPU? But wouldn't think it would being it's not exactly a weak card.

      Thank you for looking at these!

        Alright, I have tried everything you have said.
        Done several different RAM tests, no errors, reverted back to pre-crimson drivers
        tried all of the launch options mentioned

        I have pulled RAM, cables, GPU out of motherboard and reseated everything.
        Tried a fresh install of Windows 10, crashed, and am currently on a fresh install of Windows 7.



        However, I find the crashes only happen when I am streaming to twitch.tv. I have tried multiple streaming software packages (OBS is what I mainly use, tried 64 bit and 32), i have tried AMD Gaming evolved, and also X-Split.

        Here is another link to recent dumps.
        https://drive.google.com/open?id=0B7...XM0OEdkVWR3M0E

        also I have actually had some BSODs during these also. if you would like to take a look and can see something...

        Thanks again for your help

          1. BSODs show problems with your GPU driver and with some core updates missing - make sure your W7 OS is fully updated and you've installed drivers for all your devices (audio specially).
          I hope you realize gettings BSODs is unacceptable and proves your system is not stable enough, and Dota 2 has nothing to do with it!

          2. All dumps lists mssmp3 memory corruption - this is miles sound system codec used by Dota 2. This could very well be linked to 1.

          3. All dumps shows Mumble osd stuff used- it's proven to cause issues so you should disable this feature asap.
          Have you considered switching to a modern app like Discord?

          4. All dumps shows OBS recording - try changing your settings (seek advice on their forums), because the current ones are clearly not optimal (I suspect audio options)
          Since you use game capture, maybe you should check Anti-cheat compatibility hooking under it's properties. OBS settings I use (mostly for YT, I don't stream):
          Audio Encoding: AAC 44.1kHz / Bitrate=96 Channel=Stereo Audio: Desktop boost=1 Mic boost=1 Microphone Noise Gate=[ ]
          Video Encoding: x264 Use CBR=[x], Enable CBR padding=[x], Max Bitrate=3000, Use Custom Buffer=[ ]
          Advanced: Use Multithreaded optimizations=[x], Process Priority Class=Normal, Scene Buffering=1000, x264 CPU Preset=ultrafast, Encoding profile=main, Keyframe=2 for Twitch - 4 for Youtube, Use CFR=[x][/I]

          5. Windows troubleshooting options used for Dota 2 (clear any for both dota2.exe at Properties-Compatibility and Change settings for all users too)

          6. And it appears you're running Crimson edition driver again...

          - boot into Windows Safe Mode and use DDU to cleanup leftovers
          - reboot, then install a pre-Crimson driver i.e. a driver older than 24-11-2015 like 15.11.1
          - reboot again (every time you're asked)
          7. No launch options used on any of the dumps, so it runs with the default d3d9ex, so you need: -nod3d9ex -noborder

            Thank you for your help, through a lot of testing, it turned out to be a bad RAM stick. Luckily not a RAM slot.
            Cheers.
