2. Turn off the firewall in your antivirus software.

Some customers have mentioned that their firewall is interfering with their DotA 2 experience. Another option is to deactivate the Windows 10 Firewall or your antivirus’s firewall.

While this may temporarily solve the problem, you’ll be vulnerable without a firewall to protect you, particularly if you forget to switch it back on after you’ve finished playing.

Rather than deactivating your firewall, try upgrading to an antivirus program with more firewall flexibility, or at the very least, one that is easy to toggle off and on.

3. Check the game cache’s integrity.

  1. Go to Library in your Steam Client.
  2. Select Properties from the right-click menu on DotA 2.

Expert Tip: Some PC problems, such as damaged repositories or missing Windows files, are difficult to resolve. If you’re having problems repairing a mistake, it’s possible that your system is partly broken. Restoro is a tool that will scan your computer and determine the source of the problem. To download and begin mending, go here.

Steam’s integrity checker is another option for repairing broken files.

4. Keep your drivers up to date.

Disk write failures have also been linked to outdated drivers, particularly if the ones controlling your HDD are very old or have never been updated.

Unlike other hardware components, where getting the driver is as simple as going to the manufacturer’s website, these are a little tricky, and it’s better to leave them in the hands of specialised third-party software.

That is why we urge that you try our DriverFix, an almost fully automated program that can detect missing drivers, fix faulty ones, and update older ones in just a few minutes.

Simply run it, let it search your computer for faulty drivers, and then let it download and install them for you.
