Dota 2 is one of the most popular cooperative games and the most popular in the Steam gaming system.
Why is Dota 2 so popular?
Such a keen interest is caused by the fact that each new round can develop in a new way, and it does not have any clearly established plot. But, like with many games, the player may have problems.
Why doesn’t Dota 2 start?
There are many factors that can prevent a game from opening. The most common is the untimely installation of a new Dota 2 launcher. Updating sometimes does not happen automatically, so people simply don’t understand what happened to their game and why it does not start. The solution to this problem is very simple and quick: you just need to manually open your Steam account, then go to the "My Games" tab at the top and, clicking on the Dota 2 game, click "Update." After a not very long update, the game should start functioning again. After that, it would be nice to check the box "Automatic update" on Dota 2. Updating the game from now on is only a Steam system problem.

If this does not help, then you need to restart the Steam program, since it can become a stumbling block. On computers that run Windows XP Steam, it is better to run as administrator. Still not starting Dota 2? You can do some more simple things that can generally help. For example, clear the computer’s cache and restart it completely.
Further actions, if Dota 2 still does not start, are quite predictable. You can completely reinstall the video game and Steam. But do not forget that Dota 2 may not function on computers with an outdated OS, so you need to be extremely careful when downloading a file and look at compatibility.
Very often there are cases when Dota 2 does not start, and instead of the expected game, a blue or black screen crashes - the so-called "death screen", in this case there may be problems with the minimum system requirements, which most likely do not meet the requirements set by the developers of the game.
System requirements
The game has relatively low system requirements for a modern popular project. The project supports Microsoft operating systems: Windows XP / Windows Vista / Windows 7. The computer’s central processor should be at least 2.26 GHz, but with such a CPU, most likely, the FPS of the game will be at a very low level. Also, if Dota 2 does not start, then the reason for this may be a video card that does not meet the requirements. In such cases, a blue screen very often flies out and the computer starts an emergency restart due to an error that occurred in it. The minimum requirements for a video card are 512 Mb, but of course there are no guarantees that FPS will not be squandered in the game.
In many sources, the minimum requirement for computer RAM is 1 GB, but this requirement does not apply to users of Windows Vista. These users must have at least 2 GB of free RAM to play without technical interference.
A good internet connection also determines how comfortable the player will spend time in front of his screen. If this connection is rather low, then the game may regularly end on the loading of the round (in the photo on the left).
Summary
If everything has already been tried, all system requirements coincide with those that are available, then you can contact technical support on the official Dota 2 website, where they will certainly find a solution to the problem as soon as possible. After all the above steps, we can confidently say that the game Dota 2 will turn into a complete pleasure. This project with many diverse heroes and a friendly atmosphere prevailing on the servers will make you immerse yourself in it.
