    Arrow DOTA 2 Crashing? Come Here Dota 2 Crash Fix and Fixes to Errors, Freezing, Lagging

    I do not own this, but i find this guide really useful for people having crashes. Source: http://crashfixes.com

    First things first, make sure your PC system meets the minimum requirements for Dota 2. If you’re not sure of your PC specs, check this guide on how to check your PC specs. Make sure you also have a stable broadband connection!! I need to emphasize this!!

    DOTA 2 Minimum System Requirements (unofficial):
    OS: Windows« 7 / Vista / Vista64 / XP
    Processor: Pentium 4 3.0GHz
    Memory: 1 GB for XP / 2GB for Vista
    Graphics: DirectX 9 compatible video card with 128 MB, Shader model 2.0. ATI X800, NVidia 6600 or better
    Hard Drive: At least 2.5 GB of free space
    Sound: DirectX 9.0c compatible sound card

    DOTA 2 Recommended System Requirements (unofficial):

    Processor: Intel core 2 duo 2.4GHz
    Memory: 1 GB for XP / 2GB for Vista
    Graphics: DirectX 9 compatible video card with Shader model 3.0. NVidia 7600, ATI X1600 or better
    Hard Drive: At least 2.5 GB of free space
    Sound: DirectX 9.0c compatible sound card


    Problem #1 Dota 2 Crash Fix – Crash to Desktop When Loading Dota 2

    Follow these steps for a possible fix:

    Go to steamapps/common/dota2 (or dota2 beta)/ and run dota.exe
    Game will start but won’t be connected to the Steam network. This will allow you to change settings
    Change all the video settings to lowest. Set it the game to windowed mode.
    Close game
    Launch game from steam client
    Edit settings back to normal

    Problem #2 Dota 2 Crash Fix – Dota 2 Crashes After Pressing “Start Game”
    Seems to be a problem for those using nVidia graphics or nVidia-based laptops. If Dota 2 is crashing right before starting a game, try this:
    Dota 2 Crash Fix and Fixes to Errors, Freezing, Lagging, CTD, Poor FPS, Black screen, No Sound
    On Steam, go to Launch Options: look for it under Library –> On the left side menu right-click Dota 2 –> Properties –> General Tab –> Launch Options
    Type -nod3d9ex in the Launch Options input field
    Start Dota 2

    Problem #3 Dota 2 Crash Fix – Dota 2 Crashes and Cannot Load Game after getting Party Invite

    Follow these steps for a possible fix:

    Get whoever sent you the invite to restart their client
    Load up Dota 2
    Ask them not to send another invite
    Go to Dota 2 graphic settings
    Change screen ratio from 4:3 to something else

    Problem #4 Dota 2 Crash Fix – Dota 2 Crashes to desktop after MM queue (Finding a game)

    Follow these steps for a possible fix:

    Load game
    Go to Dota 2 graphic settings
    Change screen ratio from 4:3 to something else. Try different ratio options.

    Problem #5 Dota 2 Crash Fix – Crash to Desktop upon Launch / Startup

    If you’re game randomly crashes upon launching the game, ensure or try the following:

    Update your nVidia / ATI graphics drivers. Check our Technical References page for proper and official download links. - http://crashfixes.com/technical-refe...indows-mac-os/
    Turn off SLI / Crossfire then start the game. See if it stabilizes game performance.
    Turn off your anti-virus software before launching the game, but make sure you turn it back on after playing. Make sure Windows Defender is also disabled.
    Try using only one GPU first (turn the other one off via your nVidia / ATI graphics control panel)
    Try running the game in Windowed Mode (frequently works for low-end PCs)
    Disable anti-aliasing and filtering
    Disable V-sync
    Disable background apps, and turn off your anti-virus software
    In Windows 7 right-click the Dota 2 exe file, go to the ‘Compatibility Mode’ tab and check ‘Disable Desktop Composition’
    Run through our list of general fixes, which will most likely resolve your problems

    Problem #6 Dota 2 Crash Fix – Dota 2 Crashes on Intel HD Graphics Card

    Simply do a clean uninstall and reinstall of your Intel Graphics Driver. Check our Technical References page for proper and official downloads.

    Problem #7 Dota 2 Texture Fix – Bad Textures, Texture Breaks, Texture Glitch on gaming laptop

    This is only for gaming laptops, but could work for some PCs. Note that this is an advanced solution, and only try this if other basic solutions such as disabling anti-aliasing and filtering failed for you. If your BIOS has the option, disable ‘Switchable Graphics’. This will remove your laptop PC’s ability to automatically switch between the onboard intel graphics card and the nVidia / ATI graphics chip, thus smoothening out gameplay.

    Problem #8 Dota 2 Crash Fix – For Quad Core and Multi-Core PCs

    If you’re on Quad Core, try this fix to address any crash issues:

    Start the game
    Alt+Tab Out of the game
    Open Task Manager
    Right click on Dota 2.exe
    Set Affinity
    Select core 0 and 1 only. You need to run the game on two CPU’s basically, so to avoid the crash to desktop.

    Problem #9 Dota 2 Controller Fix – Xbox 360 or Other Controller Doesn’t Work

    There are two known possible solutions as of writing for this controller bug:

    Manually download and install any Dota 2 game patch from the official source instead rather than automatically updating via Steam or any similar game client.
    If you haven’t yet, go to your Windows Control Panel and ensure that the Xbox 360 Controller is enabled. Then, in-game, go to Options > Controls > Customize Controls (or similar menu path) and ensure that the proper controller is selected.

    Problem #10 Dota 2 Install Error: “Dota 2 Install Fails, Cannot Install”

    This is a Microsoft C++ bug so the quick fix is to uninstall your C++ files. If you see 2 instances of Microsoft C++, uninstall both of them; and don’t worry, they are easy to reinstall. There are also a couple workarounds online if you don’t want to uninstall them.

    Problem #11 Dota 2 Game Freeze Fix – Game Freezes during the Intro Video

    If you’re using Steam, a quick solution is to verify the integrity of your Steam game cache to resolve the problem. If it persists, ensure that both your graphics drivers and DirectX are updated. Doing both will mostly reduce the occurrences of Dota 2 freezing.

    Problem #12 Dota 2 Crash Fix – Game crashes when launching / upon launch

    This is a typical DirectX problem. Just update to the latest DirectX version and voila. If that doesn’t work, reinstall DirectX completely.

    Problem #13 Dota 2 DirectX Fix – Cannot Install Direct X / Stuck at Direct X Installation

    More often than not, this has been caused by other software drivers such as those from Logitech, Razer, Microsoft, etc, which normally control other minor peripherals such as your webcam, special programs, and sometimes your mouse. Simply shut them off and disable them, and try updating/installing Direct X again.

    Problem #14 Dota 2 Crash Fix – Possible Crash Fix for nVidia users only

    Go to Nvidia control panel by right clicking the icon in the taskbar, then manage 3d settings and set ‘Threaded Optimization’ to on.

    Problem #15 Dota 2 Graphics Fix – Cannot see main menu, Menu crashes, Dual monitor problems

    A common problem when playing on multiple screens. For now, the solution is to unplug other monitors and play on single screen. If that doesn’t work, try playing in windowed mode.

    Problem #16 Dota 2 Crash Fix – nVidia Optimus Crashes the Game

    If you’re using a newer laptop that’s using an nVidia Optimus card, try checking your Optimus settings.

    Open the “nVidia Control Panel” from your start menu.
    On the lefthand side, under “Select a task…”
    Open the “3D Settings” tree, and select “Manage 3D Settings”
    On the righthand panel, click the “Program Settings” tab.
    Under “1. Select a program…”, click “Add”, navigate to your installation folder and navigate to the application / exe file.
    Under “2. Select the preferred graphics…”, choose “High-performance NVIDIA processor”
    Then (VERY IMPORTANT!) click “Apply” in the bottom right.
    Launch the game.

    Problem #17 Dota 2 Launch Fix – Cannot launch the Game

    A common fix is clicking on the Dota 2 exe file straight from the installation folder rather than from any launcher/client.

    Problem #18 Dota 2 Sound / Audio Fix – No sound or weak sound

    For Windows 7 and Vista users:

    First of all, update your sound card drivers. If doing that doesn’t clear up the problem, make sure you have volume set to max for Dota 2 in the volume mixer (click on the little speaker icon in the bottom-right of your screen in the system tray). If you’re in-game, just alt+tab out of the game and check if Dota 2 is set to max in the volume mixer.

    Another tip you could try is to go to Control Panel > Hardware and Sound > Sound > Communications Tab then select the “Do Nothing” radio button to permanently fix this issue.


    For Windows XP users:

    Reduce hardware acceleration, or set your speakers to Stereo.

    Problem #19 Dota 2 Mouse Fix – Reverse / weird mouse acceleration problem

    To quickly fix this, try shutting off your mouse-specific software from Logitech, Microsoft, Razer, and the like. Also try a lower polling rate, sometimes this is switchable on the bottom-side of the gaming mouse.

    Problem #21 Dota 2 FPS Fix – Dota 2 Lags, freezes, or has poor FPS performance
    Try these possible solutions:

    Usually you can prevent Dota 2 from lagging or freezing by disabling vsync and antialiasing on the Dota 2’s exe file via the AMD Vision Engine Control Center (AMD/ATI) or Nvidia Control Panel (nVidia)
    Alternatively you can stop Dota 2 from lagging via your PC task manager. In Windows 7, press CTRL + ALT + DELETE and click on Task Manager, go to Processes, then right-click on Dota 2’s respective exe file and set priority above normal or higher. You must do this every time you play the game.
    In addition, your anti-virus may be the problem here. There are certain anti-virus software that are not ideal for gaming so, check our Technical References page for some suggestions.
    For more advanced users, try enabling/forcing tripple buffering and vsync using the D3DOverrider software. Check our Technical References page to download D3DOverrirder / RivaTuner.
    Finally make sure that your Internet connection is stable. This is a commonly overlooked problem especially for online modes / multiplayer games.
    If the above still do not cut it out for you, check out our tips on reducing lag.


    Problem #22 Dota 2 – Cannot Install Dota 2
    Reinstall the game, but please ensure that you’ve fully uninstalled Dota 2 from your PC, before trying to install again. In some cases, you may have to manually delete the Dota 2 installation folder from the PC in case files remain after uninstalling.

    Just to clarify, those DOTA 2 Recommended System Requirements are total bullshit. You wont get more than 20fps in 640*480 resolution with that rig.

    Pc restarts with no blue screen or crash/error messages during loading

    My pc restarts after accepting to enter a game in Dota 2. After accepting it starts loading but the loading never ends and after 15"-20" the pc restarts. (no blue screen, no error/crash messages)
    Got absolutely no idea of what is wrong. All my drivers are up to date.
    Please if anyone knows something, thank you in advance.
