According to the player feedback we have managed to gather across the communities of the game like Discord and Reddit.

Perhaps one of the most well-known workarounds to kickstarting any stuck game is to quickly reboot your system or console. It is one of the oldest tricks in the manual of video game error solutions. Players often tend to do it with multiplayer games that involve notorious glitches and crashes such as Warzone or Apex Legends.

In most cases, the errors that seem to prompt players can stem from the game freezing or repeatedly showing the same error during the login screen. Dayz is quite a huge game that is built solely on server-based matchmaking so there is no doubt you will run into problems that may require restarting the console or PC.

Alternatively, restarting the game can be a viable option too. Playstation users can do it by pressing the “Options” button and pressing the “Close Game” prompt on the menu, as shown in the image above. Meanwhile, PC users can ALT+F4 to close the game instantly or by simply quitting to the desktop.

Run the Game as Administrator

The following method is tailored for the Windows users experiencing the bios error in the game. Running the Dayz game application as admin is one of the few ways to bypass some subroutines of the errors during logging in or inside the game.

Launching the game while having it enabled under admin programming will allow it to access more system and network features for more streamlined communication with the servers and unrestricted system write access.

There are two ways through which you can run the game on administrator options:

  • Locate the Dayz main game directory in your folders, it should be in one of your Steam drives.
  • In the main folder, you will want to right-click on the “.Exe” file which is used to run the game.
  • Select the “Run as Administrator” option and select yes on the next option to confirm the settings.
  • Alternatively, you can click the Properties” option on the bottom after right-clicking on the game.
  • In the compatibility tab, just checkmark the “run this program as an administrator” setting.
  • Apply these changes and check back in the game if the bios error persists.

Verify Integrity of Game Files

PC gamers have the luxury to access a bit of a trick unique to them in the launchers of games like Steam, Battlenet, and Epic Games. It involves a tool that can verify and scan the main directory of games for any missing or corrupted vital files. It is a crucial process if the game shut down abruptly and is misbehaving on startup.

The process itself is not complicated or time-consuming to do at all. Most of the time you will want to do it as some files can get deleted in case of power outages or even random shutdowns of your system.

Since Dayz is available on Valve‘s Steam launcher. We will be looking at a quick procedure on how you can verify the integrity of game files using it. Following are the steps to do the process:

Steam verify integrity

  • Of course, make sure the game is completely turned off and not running on your desktop.
  • Locate the game in your Steam Library and click on the ‘gear’ icon just below it.
  • It will open up the properties menu of the game with various other options.
  • Navigate to the Local Files section and click on the “Verify integrity of game files” option.
  • This is will begin the process and depending on the game size can take up to 5 to 15 minutes.
  • Once it is done, the steam menu will notify you if there were any missing files to be downloaded.
  • Head back into Dayz and confirm if the bios error still occurs.

Check the PSN & Steam Server Status

It is a small chance but on rare occasions, you might find that the Playstation network services or the steam launcher might not work properly. If so, then their servers might be facing some downtime instead of the game which will also no doubt affect it since it is a multiplayer game.

Dayz operates on direct communication with the PSN & Steam regional servers to function accordingly. So it may be that the backend servers of either service can be under some sort of downtime or other issues. However, you can confirm the status of the PlayStation Network services by their Official Server Status website.

Meanwhile, steam users can check the status of Valve’s multiplayer servers on the Steam DB Server Tracker. It is a  dedicated and verified site to track a variety of key aspects related to the Steam game launcher. You can also track game prices across various regions of the launcher.

Improving your Network Connection

The last saving grace against the error might just be to upgrade your internet connectivity. It is by far the best solution when it comes to solving issues like the Bios error in Dayz or any other multiplayer-only game. There are quite a few different ways you can boost your internet speeds to play the game without any interference.

Players of 3rd world countries often are plagued with weak or unstable connections. It will result in poor quality gameplay or disconnections inside the game. In worst-case scenarios, you might encounter the game’s network errors. You will also face lag or high latency which will make the game feel unplayable to an extent.

You will need a minimum of 4MB internet speed to play a multiplayer game such as Dayz. Any frequent loss in bandwidth will hinder your gameplay with minor inconveniences so be wary of that fact.

We highly recommend investing in an ethernet cable connection from a wireless connection as it boosts your speed to be stable and smooth with your router. Speaking of which you should look into implementing a Static IP address and port forwarding of Dayz. We advise contacting your ISP and not doing it manually by yourself.


So far there is no official announcement from the Developers as to how players can prevent the bios error from occurring inside their game. But as of yesterday many outlets and communities improvised that it may just be the servers acting bizarre or under some downtime.

The servers may have come back online but there are still a handful of players who might encounter the error for no apparent reason at all. Thankfully we have listed some of the workarounds that managed to work for some players on the Discord community of the game. We hope they can help you cure the error in the game.

We will be sure to update you with any news regarding future errors in the game that may pose a bigger threat than this one. For now, we shall conclude the guide here.
