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. -
Turn off SLI / Crossfire then start the game. See if it stabilizes game performance.

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’

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 “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
