How to fix BEDaisy.sys BSOD when launching games in Windows?

Issue: Every time I attempt to launch DayZ, I keep getting BSOD, referencing the BEDaisy.sys file. How do I fix this? I can't play the game at all because these crashes just continue. 

Solved Answer

The infamous Blue Screen of Death (BSOD) in Windows is more than just a frustrating interruption. Despite its ominous name, the BSOD actually plays an important role in protecting your system. It signifies a serious issue that has occurred within the operating system, prompting it to halt immediately to prevent potential damage. The error message displayed is intended to provide a clue as to what might have triggered the crash.

One such issue that has been causing headaches for gamers recently is a BSOD related to BEDaisy.sys. When attempting to launch games such as PUBG, Escape from Tarkov, Ark: Survival Evolved, or Mount & Blade II: Bannerlord, among others, they've encountered an unwelcome crash. Typically, the error comes with an associated code like “PAGE_FAULT_IN_NONPAGED_AREA,” which provides a clue about the possible causes.

The BEDaisy.sys file is a driver associated with the Battleye anti-cheat system, which is utilized by a range of online games to prevent cheating and provide a fair gaming environment. But like any software, it's not immune to glitches. In this case, it's causing some Windows systems to crash upon launching these games.

The good news is that there are ways to resolve BEDaisy.sys BSOD. Based on the experiences of various users, several methods have proven to be effective. These include disconnecting external peripherals, reinstalling the game that's causing the crash, and reinstalling Battleye. It's also beneficial to check and fix any corrupted files on your system and reinstall your network drivers. The exact steps for performing these fixes can be found below this article.

5. Reinstall the game and Battleye

Reinstalling the game is one approach to solving BEDaisy.sys-related BSOD issues. Over time, game files can become corrupted or get modified by software updates, which may lead to instability. By reinstalling the game, you're essentially resetting all the game files to their original state, thereby eliminating any potential issues arising from corrupt or outdated files. It's crucial, however, to completely uninstall the game before reinstalling it to ensure a clean setup.

Similarly, reinstalling Battleye can also prove effective. Battleye is an integral part of the games it services, and like any other software, it can sometimes face issues that cause system crashes. Reinstalling the app helps reset its configuration and replace any damaged or missing files, resolving issues that might cause a BSOD. It is always recommended to download the latest version of Battleye from the official website or through the game client to ensure you have the most up-to-date, stable version of this anti-cheat system.

  • Once you're in the BIOS setup, look for an option named “Advanced,” “Configuration,” or something similar. Navigate through these options.

  • Change the setting for Intel Turbo Boost Technology to “Disabled.”
  • Finally, save your changes and exit the BIOS setup. This is often done by pressing F10 but look for a “Save and Exit” option to be sure.
  • Your computer should then restart with the Turbo Boost feature disabled.
